Detailed Description

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

In the description of the present invention, unless explicitly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, and may, for example, be fixedly connected, detachably connected, or integrally formed, mechanically connected, electrically connected, directly connected, indirectly connected through an intervening medium, or in communication between two elements or in an interaction relationship between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

In the present invention, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, as well as the first and second features not being in direct contact but being in contact with each other through additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are orientation or positional relationships based on those shown in the drawings, merely for convenience of description and simplicity of operation, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the invention. Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.

A light pulse device configured to act on the skin of a user may obtain input in contact with the skin of the user via a sensor. For example, the light pulse device may have one or more sensors disposed adjacent to the light exit surface that contacts the skin of the user, the one or more sensors may collect user input and cause the light pulse device to provide pulsed light output. As an example, the light pulse device may comprise a capacitive touch sensor that converts a physical or mechanical quantity when touching the skin into a capacitance change quantity and communicates information to the light pulse device to correlate the output of the pulsed light.

The user may control the output of the pulsed light of the light pulse device through an interactive interface with the electronic device. A user may use the electronic device to operate the display. During operation, a user selects a list of information about interactions and/or associated affordances of the interactive interface of the display (e.g., user finger interactions with a touch surface of the display, which include finger movements and other interactions associated with content displayed by the user). The user input may be used to control a touch output on the display. The electronic device may be used to provide corresponding tactile feedback to the user's finger. For example, haptic feedback may be used to provide a desired sensory change (e.g., vibration) to a user when the user touches an affordance of the interactive interface. Haptic feedback may also be used to produce other haptic effects or visual changing effects (e.g., changes in brightness, transparency, saturation, contrast, or other visual characteristics).

FIG. 1 is a schematic diagram of an exemplary system that may include cosmetic types. As shown in fig. 1, the system includes a plurality of devices, such as an optical pulse device and other electronic devices communicatively coupled to the optical pulse device. The light pulse device may be used to output pulsed light to act on the skin of a user to achieve cosmetic and/or skin care effects, and may be, for example, a depilatory instrument, a skin rejuvenation instrument. Electronic devices in the system may include devices such as laptop computers, computer monitors including embedded computers, tablet computers, desktop computers (e.g., displays on a stand with integrated computer processor and other computer circuitry), cellular telephones, media players, smart watches, or other wearable or miniature devices.

With one exemplary configuration (which may sometimes be described as an example in the text), the light pulse device 500 is a pulsed light output device having the function of effecting illumination of the skin of a user through a light outlet held by the user and located on one side of the device.

The light pulse device 500 and the electronic device 600 may include a control circuit 510 and a control circuit 610. Control circuitry 510 and control circuitry 610 are used to support the storage and processing circuitry of the operation of system 700 (e.g., flash memory or other programmable read-only memory configured to form a solid state drive), volatile memory (e.g., static or dynamic random access memory), etc., and processing circuitry in control circuitry 510 and control circuitry 610 may be used to collect inputs from sensors and other input devices and may be used to control output devices. The processing circuitry may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors and other wireless communication circuits, power management units, audio chips, application specific integrated circuits, and the like.

To support communication between the light pulse device 500 and the electronic device 600 and/or to support communication between equipment in the system 700 and external electronic equipment, the control circuit 510 may communicate using the communication circuit 520 and/or the control circuit 610 may communicate using the communication circuit 620. The control circuitry 510 and/or the control circuitry 610 may include an antenna, radio frequency transceiver circuitry, and other wireless and/or wired communication circuitry. For example, control circuitry 510 and/or control circuitry 610 (which may sometimes be referred to as control circuitry and/or control and communication circuitry) may support two-way wireless communication (e.g., a wireless local area network link, a near field communication link, or other suitable wired or wireless communication link (e.g., a Bluetooth link, a WiFi link, a 60GHz link, or other millimeter wave link, etc.) between light pulse device 500 and electronic device 600 via wireless link 701. The light pulse device 500 and the electronic device 600 may also include power supply circuitry for transmitting and/or wireless power and may include a battery. In configurations supporting wireless power transfer between the light pulse device 500 and the electronic device 600, inductive power transfer coils (exemplary) may be used to support in-band wireless communications.

The optical pulse device 500 and the electronic device 600 may include input-output devices, such as input-output device 530 and input-output device 630. Input-output device 530 and/or input-output device 630 may be used to gather input from a user, to gather information about the user's surroundings, and/or to provide output to the user (e.g., light pulse device 500 gathers input that it is in contact with the user's skin via a capacitive sensor, and electronic device 600 gathers input from the user's finger via a touch-sensitive display). The light pulse device 500 may include a sensor 531 and the electronic device 600 may include a sensor 631. The sensors 531 may include force sensors (e.g., strain gauges, capacitive force sensors, resistive force sensors), touch sensors and/or proximity sensors (such as capacitive sensors), optical sensors (such as optical sensors that emit and detect light), contact sensors, ultrasonic sensors (e.g., ultrasonic sensors for tracking device direction and position and/or for detecting user input such as skin input), and/or other touch sensors and/or proximity sensors, monochrome and color ambient light sensors, image sensors, sensors for detecting position, orientation and/or motion (e.g., accelerometers, magnetic sensors (such as compass sensors, gyroscopes, and/or inertial measurement units that include some or all of these sensors)), optical sensors (such as self-mixing sensors that collect time-of-flight measurements and light detection and ranging (lidar) sensors), optical sensors (such as visual ranging sensors that collect position and/or direction information using images collected in a camera), tracking sensors, infrared and/or visible light sensors with digital image sensors, moisture content, humidity sensors, and/or other sensors. In some arrangements, the light pulse device 500 and/or the electronic device 600 may use the sensor 531 and/or the sensor 631 and/or other input-output devices 530 and/or input-output devices 630 to gather user input (e.g., capacitive sensors may be used to gather contact input to the skin, and touch sensors overlapping the display may be used to gather input to the touch screen).

The input-output devices 530 and/or 630 may include other devices 533 or 633, if desired, such as a display (e.g., to display light output status in the light pulse device 500), status indicators (e.g., light emitting diodes in the light pulse device 500 and/or electronic device 600, and other light-based output devices, which serve as power indicators), speakers, and other audio output devices. The light pulse device 500 and/or the electronic device 600 may also include power transmission and/or reception circuitry configured to transmit and/or receive wired and/or wireless power signals.

In the following discussion, an electronic device including a display and a touch-sensitive surface is described. However, it should be understood that the electronic device optionally includes one or more other physical user interface devices, such as a physical keyboard, mouse, and/or joystick.

The electronic device typically supports various applications such as one or more of a drawing application, a presentation application, a spreadsheet application, a word processing application, and/or a health management program.

The various applications executing on the electronic device optionally use at least one generic physical user interface device, such as a touch-sensitive surface. One or more functions of the touch-sensitive surface and corresponding information displayed on the device are optionally adjusted and/or changed for different applications and/or within the respective applications. In this way, the common physical architecture of the devices (such as the touch-sensitive surface) optionally supports various applications with a user interface that is intuitive and transparent to the user.

Touch sensitive displays of electronic devices are sometimes referred to for convenience as "touch screens" and sometimes referred to as "touch sensitive display systems". The electronic device includes memory, a memory controller, one or more CPUs (Central Processing Unit, processing units), a peripheral interface, RF (Radio Frequency) circuitry, audio circuitry, speakers, microphones, input/output (I/O) systems, other input control devices, and external ports. The electronic device optionally includes one or more detection devices (e.g., a contact sensor for detecting the electronic device's adherence to the skin for use).

It should be understood that the electronic device optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. FIG. 2 illustrates exemplary interactions of an electronic device with a control interface at a user interface, the interaction interface shown in the figures being implemented in hardware, software, or a combination of both, with presentation of the different interfaces being accomplished through contact interactions with a user.

The memory optionally includes high speed random access memory, and optionally also non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid state memory devices. The memory controller optionally controls other components of the electronic device to access the memory.

The peripheral interface may be used to couple input peripherals and output peripherals of the electronic device to the CPU and memory. The one or more processors execute or perform various software programs and/or sets of instructions stored in the memory to perform various functions for the electronic device and process data. In some embodiments, they are optionally implemented on separate chips.

The RF circuit receives and transmits RF signals, also known as electromagnetic signals. The RF circuitry converts/converts electrical signals to/from electromagnetic signals and communicates with a communication network and other communication devices via the electromagnetic signals. The RF circuitry optionally includes well known circuitry for performing these functions including, but not limited to, an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, memory, and the like.

The audio circuit, speaker and microphone provide an audio interface between the user and the electronic device. The audio circuit receives audio data from the peripheral interface, converts the audio data to an electrical signal, and transmits the electrical signal to the speaker. The speaker converts the electrical signal into sound waves that are audible to humans. The audio circuit also receives an electrical signal converted from sound waves by the microphone. The audio circuit converts the electrical signal into audio data and transmits the audio data to the peripheral interface for processing.

Input/output (I/O) systems couple input/output peripheral devices on electronic devices, such as touch screens and other input control devices, to the peripheral device interface. An input/output (I/O) system optionally includes a display controller, an optical sensor controller, a haptic feedback controller, and one or more input controllers for other input or control devices.

The touch screen provides an input interface and an output interface between the electronic device and the user. The display controller receives electrical signals from and/or transmits electrical signals to the touch screen. The touch screen displays visual output to the user. Visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively, "graphics"). In some embodiments, some or all of the visual output optionally remains corresponding to the user interface object.

The touch screen has a touch-sensitive surface, sensors, and sensor groups that accept input from a user based on haptic and/or tactile contact. The touch screen and the display controller detect contacts on the touch screen and convert the detected contacts into interactions with user interface objects displayed on the touch screen. In an exemplary embodiment, the point of contact between the touch screen and the user corresponds to a finger of the user.

In some embodiments, the electronic device optionally includes a touch pad for activating or deactivating specific functions in addition to the touch screen. In some embodiments, the touch pad is a touch sensitive area of the device that, unlike a touch screen, does not display visual output. The touch pad is optionally a touch surface separate from the touch screen or an extension of the touch surface formed by the touch screen.

The electronic device also includes a power system for providing power to the various components. The power system optionally includes a power management system, one or more power sources (e.g., capacitors, ac power, recharging system, power status indicators), and any other components associated with the generation, management, and distribution of power for the electronic device.

In some embodiments, the software components stored in the memory include an operating system, a communication module (or set of instructions), a contact/motion module, a graphics module, a text input module (or set of instructions), a positioning system (or set of instructions), and an application program (or set of instructions).

An operating system (e.g., iOS, android, OS X, windows, or embedded operating systems such as VxWorks) includes various software components and/or drivers for controlling and managing general task systems (e.g., storage management, storage device control, power management, etc.), and facilitates communication between the various hardware components and software components.

The communication module facilitates communication with other devices through one or more external ports and also includes various software components for processing data received by the RF circuitry and/or external ports. External ports (e.g., USB (Universal Serial Bus, universal serial bus), firewire, etc.) are suitable for coupling directly to other devices, or indirectly through a network.

The graphics module includes various known software components for rendering and displaying graphics on a touch screen or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual characteristics) of the displayed graphics. As used herein, the term "graphic" includes any object that may be displayed to a user, including without limitation text, web pages, icons (such as including software user interface objects), digital images, video, animation, and the like.

In some embodiments, the graphics module stores data representing graphics to be used. Each graphic is optionally assigned a corresponding code. The graphics module receives one or more codes for formulating graphics to be displayed from an application program or the like, and if necessary, receives coordinate data together with other graphics data, and then generates screen image data for output to a display.

Examples of other applications optionally stored in memory include other word processing applications, other image editing applications, drawing applications, presentation applications, JAVA-enabled applications, encryption, digital rights management, speech recognition, and speech replication.

As used herein, the term "affordance" refers to a user-interactive graphical user interface object that is optionally displayed on a display of electronic device 100, 200, and/or 500. For example, an image (e.g., an icon), a button, and text (e.g., a description of a human body part) optionally each constitute an affordance.

An exemplary system for an electronic device is shown in fig. 3A. In operation, the electronic device receives user input (e.g., clicks on the "private portion"). In some embodiments, the user input includes a finger touch of the user. Based on the finger's touch, the web server identifies one or more tasks and parameters. For example, a web server interprets a textual representation of the user's input to derive intent and define intent operationality into one or more tasks. In the illustrated embodiment, based on the user clicking on "private parts," the web server identifies the task as finding a list of medical solutions related to "private parts.

In addition, the web server transmits a request for "private parts" input by the user to the identity storage means. The request includes one or more parameters identifying the "private portion". In some embodiments, one or more parameters may specify a naming pattern (e.g., "six pulses"), a light pulse intensity (e.g., "intensity"), and/or an attribute that affects hair thickening (e.g., "hair thickening").

The identity storage device may store data and/or models of a plurality of attributes associated with the user input site affordance (e.g., a "private site"). Attributes that may be stored for the electronic device include, but are not limited to, unique identifiers, light pulse output parameters, body part identifiers, burst interval durations, and the like. For example, the identification storage device may store identifier information associated with the input location affordance "private location", the location affordance "perilabial location", and the associated identifier information may include a private location having a dense hair attribute and a perilabial location having a sparse hair attribute.

The identity store may be implemented via hardware, software, or a combination of both. In some embodiments, the identification storage device may be located on one or more of the light pulse device and the electronic device.

In some embodiments, the location-enabled representation (e.g., a "private location") in the list of schemes is identified based on parameters provided in the request from the network server at the identification store. In some embodiments, the identity store determines whether an electronic device having an entry in the database has an attribute that matches the parameter. In some embodiments, the electronic device receives a request from a user for a location affordance (e.g., a "private location") to identify and provides data matching the identification storage device via the web server. The electronic device responds to receiving the parameters from the web server and provides the combined commands (e.g., including control commands entered at other control pages) to the light pulse device. In the embodiment shown in FIG. 3A, the conjoined command includes the text string "07 01, 11C1 7F". In response to the received combined command, pulsed light (e.g., a six-pulse train) of parameters of the associated site affordance is output at the light pulse device. In some embodiments, for a region affordance that is different body regions but has the same attribute (e.g., different body regions associated with a user each have a characteristic of hair thickening), the electronic device may receive a request from the user's region affordance (e.g., "an axillary region") to identify (the axillary region having at least partially the same light pulse output parameters as the "private region", e.g., "six pulse" output form) and provide parameters matching thereto to an identification storage device via the network server, the identification and other identifications having the same attribute each being operable to instruct the light pulse device to output light at least partially the same parameters (e.g., both the axillary region and the private region may output six pulses of light, or both the perilabial region and the body region may output two pulses of light).

Another exemplary system for an electronic device is shown in fig. 3B. In operation, the electronic device receives user's finger 01 input (e.g., clicks on the "private portion"). In some embodiments, the light pulse electronics may include an identification storage device. At the identity storage, based on a command output (e.g., text string "07 01 11c 17 f") from the electronic device providing an associated site affordance (e.g., a private site), the identity storage determines whether a light pulse device having an entry in the database has an attribute matching a parameter, the light pulse device responsive to receiving the parameter from the identity storage, and outputting pulsed light (e.g., outputting double pulse light, four pulse light, six pulse light, eight pulse light, or ten pulse light) associated with the parameter.

FIG. 2 illustrates exemplary interactions of an electronic device with a control interface at a user interface. In some embodiments, the home page of display 101 provides affordances of list options (e.g., affordance 130a for a "list of solutions" and affordance 130b for a "my plan"), the user accesses the first user interface 110 by touching the affordance for a selection of the list of solutions, in which first user interface 110 electronic device 100 displays affordances corresponding to different parts of the body including, for example, perioral affordance 140a, body part affordance 140b, underarm affordance 140c, and privacy affordance 140d, and provides textual representations 141a-d, respectively, that include representations showing these representative body parts. Since the perilabial and body parts have the property of thin hair, while the underarm and private parts have the property of thick and stiff hair, the corresponding affordances of these parts are each associated with identifying information of their corresponding properties to mark that these parts may be associated with pulse light output functions of different parameters in subsequent secondary interactive interfaces (e.g., the affordances of perilabial and body parts are associated with pulse light output functions of double pulses, and the affordances of the underarm and private parts are associated with pulse light output functions of six pulses). Therefore, the pulse light output functions of different positions can be marked and configured by selecting different position affordances. This provides a more efficient interactive experience for the user to perform the desired functions with the electronic device and/or the light pulse device.

In some embodiments, the user clicks on the private portion affordance 140d and the electronic device 100 detects the first interface input 102 corresponding to a selection of the private portion affordance 140d in the first user interface 110. In fig. 2, the display 101 displays a first control interface 120a. An affordance corresponding to each execution function of the light pulse device is displayed in the first control interface 120a, including a first control affordance 121, where the first control affordance 121 corresponds to an option representation of an associated electronic device having an on/off SHR (Super Hair Removal, super-dehairing) function. The first control affordance 121 includes a first control functional switch representation 1211 that, when illuminated, represents a current on state in the SHR mode (continuous output of multiple pulses, e.g., double, four, six, etc., in one light cycle) and when off, represents a current off state in the SHR mode (only one pulse of light output is provided in one light cycle, with an energy value that is lower than the sum of the multiple pulse energies in the SHR mode). In some embodiments, the user inputs the privacy zone representation 140d via the first user interface 110, the input associated with the second identifying information corresponding to the privacy zone, and the electronic device 100 detects whether the function switch representation 1211 of the first control in the first control affordance 121 is on. In response to detecting the activation of the function switch representation 1211, the electronic device 100 transmits a second function command to the light pulse device associated with the second identification information (e.g., the light pulse device performs a six pulse burst scheme, i.e., a six pulse SHR mode, within one light cycle). In other embodiments, the user inputs the perilabial area representation 140a via the first user interface 110, the input associated with first identification information corresponding to the perilabial area, and the electronic device 100 detects whether the function switch representation 1211 of the first control in the first control affordance 121 is on. In response to detecting the activation of the function switch representation 1211, the electronic device 100 transmits a command to the optical pulse device for a first function associated with the first identification information (e.g., the optical pulse device performs a double pulse burst scheme, i.e., a double pulse SHR mode) within one optical period. Displaying the same control affordance and setting on the same control interface provides a more efficient control interface for different light output control for different body parts. Allowing a user to access a control interface having the same control affordance from the same user interface reduces the cognitive burden on the user. And, the user does not need to open the associated control interface for each part independently in the application program for independent configuration. In addition, the opening and closing of the affordance of the control corresponds to the execution of two different functions, so that a user can more effectively implement operations and controls on the control interface without having to independently operate the affordance of the same type of control (e.g., opening or closing of single and double flashes).

Fig. 4A-4D illustrate exemplary interactions of the first control interface when selecting the privacy zone affordance 140D.

The first control interface 120a is displayed with three states of control affordances.

In fig. 4A, the electronic device 100 displays a first control interface 120a at the display 101, the first control interface 120a displaying a first control affordance 121 corresponding to the SHR function, a second control affordance 122 corresponding to the flash periodicity function, and a third control affordance (123 a, 123 b) corresponding to the energy adjustment function in the light pulse device, while the first control interface 120a also displaying a graphical affordance 142d associated with the privacy zone and a graphical affordance 125 related to dynamic changes in the light pulse device output (e.g., in the out-light state, the graphical affordance 125 has a representation of an out-light diagram; in the no-light state, the graphical affordance 125 has a representation of a still graph). In response to the first control input 103 to the first control affordance 121 (the functional switch representation 1211 of the first control being in an on state), the electronic device 100 transmits a command to the light pulse device for a first function associated with first identification information to execute a six pulse burst scheme within one light cycle.

In fig. 4B, a first control affordance 121 corresponding to a first control affordance for SHR (Super Hair Removal/super-dehairing) functionality in a light pulse device, a second control affordance 122 for a flash periodicity functionality, and a third control affordance (123 a, 123B) for an energy adjustment functionality are displayed in a first control interface 120a, the second control affordance 122 including a function switch representation 1221 of the second control that, when activated, is associated with a display of the text representation "flash" and, when inactive, is associated with a display of the text representation "single flash". In some embodiments, in response to a first control input to the first control affordance 121 (the functional switch representation 1211 of the first control being in an on state) and a second control input 104 of the second control affordance 122 (the functional switch representation 1221 being in an active state), the electronic device 100 transmits to the light pulse device a command of a first function and a command of a third function associated with the first identification information, wherein the command of the third function is to instruct the light pulse device to continuously perform light output in a plurality of light cycles. In some embodiments, the light pulse device includes a touch sensor, and the light pulse device triggers one or more cycles of continuous light output in response to each touch of the touch sensor to the user's skin. In some embodiments, each time the user contacts the light outlet of the light pulse device with the skin, the light pulse device may acknowledge the trigger signal via the contact sensor, thereby enabling the light pulse device to perform a succession of multiple photoperiods to automatically pulse the light output each time the light pulse device contacts the skin of the user multiple times in succession, and to perform one photoperiod of output each time the contact performs (e.g., one photoperiod performs six pulses of pulsed light output, or one photoperiod performs two pulses of pulsed light output).

In fig. 4C, a first control interface 120a displays a first control affordance 121 corresponding to a SHR function, a second control affordance 122 corresponding to a flash periodicity function, and a third control affordance (123 a, 123 b) corresponding to an energy adjustment function in the light pulse device, the third control affordance including a third control affordance 123a for energy downshifting and a third control affordance 123b for energy upshifting, both of which are separately adjustable output parameters (e.g., pulse power and/or pulse width) of the pulsed light in response to user input to the third control affordance, and the display 101 displays a text representation 124 of an energy shift at the first control interface 120 a. In some embodiments, in response to a first control input to the first control affordance 121 (the function switch representation 1211 of the first control is in an off state), a second control input to the second control affordance 122 (the function switch representation 1221 of the second control is in an inactive single flash state), and a third control input 105 of the third control affordance (the text representation 124 of energy gear 3), the electronic device 100 outputs a command of the second function, a command of the third function (single flash), and a command of the fourth function (energy value 3) to the light pulse device in association with the second identification information.

In fig. 4D, a first control interface 120a displays a third control affordance (123 a, 123 b) corresponding to a first control affordance 121, a second control affordance 122, and a third control affordance (123 a, 123 b) of a flash periodicity function for an SHR function in the light pulse device, the third control affordance including a third control affordance 123a of an energy downshift and a third control affordance 123b of an energy upshift. In response to the first control input to the first control affordance 121 (the functional switch representation 1211 of the first control being in an on state), the second control input 104 of the second control affordance 122 (the functional switch representation 1222 of the first control being in an inactive, single flash state), and the third control input 105 of the third control affordance (the text representation 124 of energy gear 1), the electronic device 100 outputs to the light pulse device a command (six pulses of pulsed light output) of the second function, a command (single flash) of the third function, and a command (energy value 1) of the fourth function associated with the second identification information.

The electronic device has another list interface between interactions of the user interface and the control interface to provide a more thorough planning scheme for the user.

FIG. 4E illustrates a list interface of the electronic device during interaction of the user interface with the control interface. In some embodiments, the user first jumps to list interface 120b by touching the affordance of the selection scheme list, displaying a programmatic list indication corresponding to the affordance of the location in list interface 120 b. In some embodiments, the user enters the private portion affordance 140d and then enters the list interface 120b, and the list interface 120b displays a plurality and/or sets of affordances with time period plans associated with the private portion affordance 140d, including one or more completed affordances 150a, one or more to-do affordances 150b, and one or more incomplete affordances 150c. In some embodiments, after each execution of the pulsed light output by the user, the electronic device 100 and/or the light pulse device stores execution information for the current pulsed light output, including data and/or models and related information for one or more attributes associated with the location (e.g., the private location), and after the user next touches and selects the location affordance (e.g., private location affordance 140 d) associated with the execution information, an update interface corresponding to the planned list indication of the associated private location affordance 140d is displayed in the list interface 120b, including one or more completed affordances 150a, one or more to-do affordances 150b, and one or more unfinished affordances 150c. In some embodiments, the completed affordance 150a is associated with a display of a graphical affordance 151a (e.g., the execution scheme has been completed, the graphical affordance 151a has an identification of a "v" graphic), a display of a textual representation 152a (e.g., the text "privacy therapy 1") accompanied by a display of an execution status textual representation 153a (e.g., the text "completed"), a display of a to-do affordance 150b associated with a graphical affordance 151b (e.g., the graphic with "lock" open), a display of a textual representation 152b (e.g., the text "privacy therapy 2") accompanied by a display of an execution status textual representation 153b (e.g., the text "to complete"), and a display of an incomplete affordance 150c associated with a graphical affordance 151c (e.g., the graphic with "lock" closed), a textual representation 152c (e.g., the text "privacy therapy 3") accompanied by a display of an execution status textual representation 153c (e.g., the text "not unlocked"). In some embodiments, the incomplete affordance 150c in the unoccluded state has a different visual impact display (e.g., brightness, transparency, saturation, contrast, or other visual characteristic) than the completed affordance 150a, the to-be-completed affordance 150 b.

Fig. 5 illustrates an exemplary interaction of the electronic device with the second control interface at the first user interface, and fig. 6 illustrates an interaction interface of the second control interface 120c when the user selects the body part affordance 143 b. In some embodiments, the home page of the display 101 provides affordances of list options (e.g., affordance 130a for a "project list" and affordance 130b for a "my project" for example), and the user enters these lists into the first user interface 110 by touching them, where the electronic device 100 displays affordances corresponding to different parts of the body involved and displays affordances with free choice for indicating that the user can freely select and light output for any part of the body without having to individually perform each part-associated control input across one or more interactive interfaces by the user, simplifying user interaction with the interface so that the operation of the parts and controls can be accomplished at one interface rather than having to follow the operations of each part in FIG. 4E that require sequential unlocking through the various project-planning list indications, or such as in FIG. 2 that the control can be accomplished after selection. The two types of affordances (the type of affordance for each part of the body and the type of affordance that can be freely selected) are displayed on the same user interface, providing a user with a higher degree of freedom in use and interactive experience.

In some embodiments, the user clicks on the free-choice affordance 140e, the electronic device 100 detects a second interface input 106 corresponding to a selection of the free-choice affordance 140e in the first user interface 110, and the display 101 displays a second control interface 120c. In the second control interface 120c, the electronic device 100 displays affordances corresponding to different parts of the body (e.g., perilabial part affordance 143a, body part affordance 143b, underarm part affordance 143c, and/or privacy part affordance 143 d) in the scene portion 126, and provides text and graphic representations including representations showing these representative body parts (e.g., body part affordance 143b has associated body part graphical representation 1431 and body part text representation 1432), respectively. The affordances of these different sites can represent data and/or models and related information having attributes corresponding to their associated sites, including, but not limited to, unique identifiers, light pulse output parameters, body-site identifiers, pulse-train interval durations, and the like. In the second control interface 120c, the electronic device 100 displays affordances corresponding to the respective execution functions of the light pulse device at the function selection portion 127, including a first control affordance 121, a second control affordance 122, and a third control affordance. The first control affordance 121 corresponds to an option representation of an associated electronic device having an on/off SHR function. The first control affordance 121 includes a first control's functional switch representation 1211 that when illuminated, represents a current on state and when extinguished, represents a current off state of the functional switch representation 1211. The second control affordance 122 includes a functional switch representation 1221 of the second control that has associated therewith a display of the text representation "flash" when the functional switch representation 1221 is active and a display of the text representation "single flash" when it is inactive. The third control affordance includes a third control affordance 123a for energy downshifts and a third control affordance 123b for energy upshifts, both of which can each adjust an output parameter (e.g., pulse power and/or pulse width) of the pulsed light as corresponding to user input.

In some embodiments, the electronic device 100 is responsive to user input of the part affordance (e.g., a body part) at the second control interface 120c and displays the body part affordance 143b as a different visual change effect (e.g., a change in brightness, transparency, saturation, contrast, or other visual characteristic) at the display 101 than the other part affordances to inform the user of the correct representation of the input. The electronic device 100 takes input of the body part affordance 143b and refreshes the pulse light output parameters (e.g., double or six pulses, continuous or single flashes, pulse power and/or pulse width) corresponding to the plurality of functional switch representations (e.g., the first control affordance 121, the second control affordance 122, and the third control affordance) associated with the functional selection text representation 127. Subsequently, the user makes touch inputs (e.g., touches the display 101 to input the function switch representation 1211 of the first control, the function switch representation 1221 of the second control, the third control affordances (123 a, 123 b)) in accordance with the display states of the plurality of function switch representations. The control interface is convenient, free and efficient for a user, and the user does not need to select functional schemes corresponding to different body parts through a plurality of hierarchical interfaces, so that the cognitive burden and the operation complexity of the user are reduced.

Fig. 7 illustrates an exemplary interaction of the electronic device with the first control interface 120a at the second user interface 111. In some embodiments, the home page of the display 101 provides affordances of list options (e.g., affordance 130a for a "list of solutions" and affordance 130b for a "my plan"), the affordance 130b for user touch input "my plan" entering into the second user interface 111, the second user interface 111 comprising a first location information representation and a second location information representation, the first location information representation representing commands associated with each transmission of an executed command to the controllable external light pulse device as a first function, the second location information representation representing commands associated with each transmission of an executed command to the controllable external light pulse device as a second function different from the first function, a second user interface input 107 responsive to either selection of the first location information representation and the second location information representation, and the first control interface 120a is displayed on the display device in accordance with the second user interface input 107.

In some embodiments, the second user interface 111 includes planning information associated with a plurality of body parts that can provide the user with a schedule of progress regarding treatment of each part in order to provide more efficient interface interactions. For example, the second user interface 111 includes location information representations 144a-144b associated with respective locations to indicate information affordances 144a1-144d1 associated with the location information representations, the information affordances 144a1-144d1 for providing a user with an indication of completion of a pulsed light execution plan for the respective locations (e.g., having a text representation "rest" to tell that light operation is not being performed for the location today, and/or a text representation "to do" to tell that light operation is being selectively entered and completed today, and/or a text representation "done" to tell that light operation has been performed today), and progress affordances 144a1-144d1 (e.g., text representation "done 3/10 times") to indicate, respectively, that the progress affordances 144a1-144d1 store the current execution record each time the user has a pulsed light output, and update the display of the progress affordances 144a1-144d1 upon the next user entering the second user interface 111. Through the interaction of the second user interface 111 and entering the first control interface 120a, a richer way of performing the interaction by the pulsed light is provided for the user, and the interaction is convenient for the user equipment to store the plan or set the plan to perform the pulsed light output of each time, so that a more flexible and more efficient use experience is provided for the user.

8A-8B illustrate an exemplary control interface according to some embodiments. The user interfaces in these figures are used to illustrate the processes hereinafter.

Fig. 8A shows an electronic device 200 with a display device 201. In some embodiments, the display device 201 displays a second control interface 210. At the second control interface 210, the electronic device 200 displays affordances corresponding to different parts of the body (e.g., perioral part affordances 220a (partially shown), body part affordances 220b, armpit part affordances 220c, and privacy part affordances 220d (partially shown)), which can be manipulated by a user by sliding the touch screen of the display device 201 to control the appearance and operation of the affordances of the respective different parts. The affordances of these locations are freely selectable and provide a targeted light output to the user. The affordances of these different sites can represent data and/or models and related information having attributes corresponding to their associated sites, including, but not limited to, unique identifiers, light pulse output parameters, body-site identifiers, pulse-train interval durations, and the like. The second control interface 210 also displays a first control affordance 230, a second control affordance 240, and a third control affordance. The first control affordance 230 corresponds to an option representation of an associated electronic device having an on/off SHR function. The first control affordance 230 includes a functional switch representation 231 of the first control that, when illuminated, represents a current on state in SHR mode and, when extinguished, represents a current off state in SHR mode, the light pulse device can only output a single pulse. The second control affordance 240 includes a functional switch representation 241 of the second control that has associated therewith a display of the text representation "flash" when the functional switch representation 241 is activated and a display of the text representation "single flash" when it is inactive. The third control affordance includes a third control affordance 250a for energy downshifts and a third control affordance 250b for energy upshifts, both of which can each adjust an output parameter (e.g., pulse power and/or pulse width) of the pulsed light upon user input.

In some embodiments, the electronic device 200 is responsive to user input of the part affordance (e.g., an underarm part) at the second control interface 210 and displays the body part affordance 220c as a different visual change effect (e.g., change in brightness, transparency, saturation, contrast, or other visual characteristic) at the display device 201 than the other part affordances to inform the user of the correct representation of the input. The electronic device 200 obtains the input 108 of the body part affordance 220c and refreshes the pulsed light parameters (e.g., double or six pulse, continuous or single flash, pulsed power, and/or pulse width) corresponding to the associated plurality of functional switch affordances (e.g., the first control affordance 230, the second control affordance 240, and the third control affordance). Subsequently, the user makes touch inputs (e.g., inputs the function switch representation 231 of the first control, the function switch representation 241 of the second control, the third control affordance (250 a, 250 b)) at the display device 201 according to the display states of the plurality of function switch representations. The control interface is more convenient, free and effective for the user, and the user does not need to select the functional schemes corresponding to different body parts through interaction of a plurality of hierarchical interfaces, so that the cognitive burden and the operation complexity of the user are reduced. And is applied to miniaturized electronic equipment (such as a watch), thereby being more convenient for improving the interaction convenience of users.

Fig. 8B shows yet another example of an electronic device 200 with a display device 201, the electronic device 200 being communicatively connected to a light pulse device 300. Unlike the previous embodiment, at the display device 201, the electronic device 200 obtains input of the body-part affordance 220b at the second control interface 210, the body-part affordance 220b also having associated therewith a display of a graphical affordance 220b1 and a textual representation 220b2 of the body-part. Meanwhile, the functional switch representation 231 of the first control is in the SHR off state and the functional switch representation 241 of the second control is in the flash state.

In some embodiments, the light pulsing device 300 instantaneously releases high energy light through an internal xenon lamp and transmits the light energy through a light transmissive crystal to the skin for epilation and/or skin care purposes.

Fig. 9 shows a partial structural example of an optical pulse device having a light-transmitting crystal. The light pulse device 300 is provided with one or more sensors 320 located at the peripheral side of its light outlet, the sensors 320 being configured to be inside the housing surface 311 or at least partially exposed to the outside, and when a user holds the light pulse device 300 in hand and contacts the skin, the sensors 320 acquire a contact signal and feed back to the processor of the light pulse device 300. In some embodiments, the light pulse device 300 automatically performs one or more photoperiod of pulsed light according to the contact signal, e.g., the light pulse device outputs one photoperiod of pulsed light and stops outputting after receiving the contact signal until the user lifts the device and outputs again after the next detection of the contact signal.

Fig. 10A shows a schematic of the sensor 320 located inside the housing surface 311, and fig. 10B shows a schematic of the sensor 320 at least partially exposed. In some embodiments, the light emitted by the light source irradiates the skin of the user through the light-emitting surface 331 of the transparent crystal 330. The light emitting surface 331 is slightly protruded from the housing surface 311, so as to ensure that the light emitting surface 331 is in a close contact state for sufficiently pressing the skin of the user when the electronic device obtains a contact signal through the sensor 320. In some embodiments, the light emitting surface 331 protrudes 1mm from the surface of the housing.

In some embodiments, the light pulse device 300 may include a capacitive touch sensor that converts a physical or mechanical quantity when in contact with the skin into a capacitance change quantity and communicates information to the light pulse device to correlate the output of the pulsed light. The sensors 320 may include force sensors (e.g., strain gauges, capacitive force sensors, resistive force sensors), touch sensors and/or proximity sensors (such as capacitive sensors), optical sensors (such as optical sensors that emit and detect light), contact sensors, ultrasonic sensors (e.g., ultrasonic sensors for tracking device direction and position and/or for detecting user input such as skin input), and/or other touch sensors and/or proximity sensors, monochrome and color ambient light sensors, image sensors, sensors for detecting position, orientation and/or motion (e.g., accelerometers, magnetic sensors (such as compass sensors, gyroscopes, and/or inertial measurement units that include some or all of these sensors)), optical sensors (such as self-mixing sensors that collect time-of-flight measurements and light detection and ranging (lidar) sensors), optical sensors (such as visual ranging sensors that collect position and/or direction information using images collected in a camera), tracking sensors, infrared and/or visible light sensors with digital image sensors, moisture content, humidity sensors, and/or other sensors.

In some embodiments, the sensor 320 is arranged as a touch sensor, and the light pulse device 300 triggers one or more periods of continuous light output in response to each touch of the touch sensor on the user's skin. In some embodiments, the user may perform a plurality of photoperiod continuous light outputs each time the light outlet of the light pulse device is contacted with the skin and the trigger signal is confirmed by the contact sensor 320, thereby realizing that the light pulse device continuously contacts the skin of the user a plurality of times, and perform one photoperiod output each time (e.g., one photoperiod performs six pulses of light output or one photoperiod performs two pulses of light output). In some embodiments, the housing surface of the light pulse device is configured with a confirmation physical key that pulses light to perform. Under the application scene of triggering continuous light emitting of a photoperiod, the light emitting port contacts the skin, the light pulse equipment receives a contact signal, at the moment, the light pulse equipment does not emit light, and after a user presses a physical key, the pulse light of a photoperiod is output and stops outputting, until the user removes the equipment and repeats the operation mode after the light emitting port contacts the skin next time. In an application scene of triggering continuous light output of a plurality of photoperiods, the light outlet contacts the skin, the light pulse equipment receives a contact signal, at the moment, according to the contact signal, the light pulse equipment executes pulse light output of one photoperiod, after the light pulse equipment stops, a user moves away the equipment, and as the user moves away the equipment, the light pulse equipment breaks the received contact signal, the light pulse equipment does not emit light until the contact signal is received again, and executes pulse light output of a subsequent photoperiod, and the light pulse equipment is continuously executed repeatedly for a plurality of times.

In the following discussion, a method of outputting an optical pulse device is described.

The light pulse device is provided with a sensor for acquiring a contact signal generated when a user touches the skin, and meanwhile, pulse light matched with the contact signal is correspondingly output after the contact signal is determined based on a light-emitting scheme stored by the light pulse device and/or a light-emitting scheme stored by an electronic device in communication connection with the light pulse device. In some embodiments, the light source provides the light described above using, for example, a xenon lamp, which upon excitation by a high voltage, instantaneously releases pulsed light energy to act upon the target tissue. In some embodiments, the light is released with a light pulse train (i.e., consisting of a plurality of pulses) as a light cycle, and the configured light pulse train acts on the target tissue and achieves the desired light effect.

In the prior art, the optical pulse train within one photoperiod has a form configured as a sub-pulse consisting of two pulse energy values that are incremented. The pulse energy value of each sub-pulse is determined by the pulse power and the time (i.e. pulse width), and the user releases energy to the skin through the pulse light, so that the energy can penetrate the epidermis and reach the target tissue, and the aim of dehairing and/or skin rejuvenation is achieved by applying the energy to the target tissue. With the release of energy in each photoperiod, a higher pulse energy value means that the user's body feel is more pronounced (e.g., warmth, tingling and/or burning), with no or warmth being desired. The energy release of the double pulse sets the desired burst energy value to two sub-pulses with increasing gradients, achieves the desired preheating after the target tissue is acted upon by the first sub-pulse, and releases the second sub-pulse with a higher pulse energy value again after the desired pulse interval is stopped, which allows the user to accept release with increasing energy gradients in one photoperiod, thereby resulting in optimization in the sensation of motion (e.g., reduced tingling and/or burning sensation). But this arrangement ignores the problem of variability of the target tissue in different areas. For example, the light pulse device is an epilator, since the human body has skin properties and/or hair properties that vary greatly in various parts (e.g. hairs around lips are relatively sparse and soft and hairs under armpits are relatively thicker), the pulse energy values of the second sub-pulse are often configured higher for the purpose of achieving the epilation for e.g. the hair thickness properties, or the first sub-pulse and the second sub-pulse are each configured to a higher level for pulse energy values, to ensure that the total pulse energy value meets the epilation purpose, or neither the first sub-pulse nor the second sub-pulse has a higher pulse energy value for ensuring comfort, which makes it necessary for the user to perform multiple pulse light outputs to the same area. It is apparent that, in whatever way, any one of the sub-pulses provides the pulsed light of higher pulse energy to the target tissue, it may cause the user's skin to have an unexpected negative effect (e.g., tingling and/or burning) due to the pulsed light of high pulse energy value, or the user may not be able to achieve the desired hair removal without contacting the skin at one time. As another example, fig. 11 shows a schematic diagram of performing double pulses in one photoperiod in the prior art, fig. 11. The double pulse is configured to have a pulse width of 0.3ms and to perform a pulse light energy release of a second sub-pulse having a pulse width of 6ms after a pulse interval of 0.6s, which configuration has proved to be effective for hair properties with sparse characteristics, but since the energy superposition value is low and the energy of the second sub-pulse cannot provide an untimely higher energy, once designed to provide, it may lead to the skin having an intolerable tingling and/or burning sensation, so that the double pulse cannot effectively cope with hair regions having coarse hard properties. To this end, the following provides an improvement in the configuration of the light pulse trains and provides a light output pattern to target differential light energy release at different areas of the user's skin.

Specifically, in one optical pulse train, the optical pulse train is configured to continuously output N sub-pulse trains, each of which has M sub-pulses therein and each of which has a preset pulse energy value, which can be determined by a pulse power and a pulse width definition, N and M being each configured as integers greater than or equal to 2, in the N-1 th sub-pulse train, the M-th sub-pulse has a first pulse energy value integral J1, in the N-th sub-pulse train, the M-th sub-pulse has a second pulse energy value integral J2, wherein J1< J2. The effective energy value superposition for a light pulse train released in a light cycle is often more dependent on the energy release of the last sub-pulse train for the target tissue, i.e. in the early phase of the last sub-pulse train release, the other sub-pulse trains can be regarded as superposition of energy bases to make the skin adapt to the discomfort caused by the energy superposition, or the other sub-pulse trains provide energy accumulation values for the last released sub-pulse train for more ideal reaching to the target tissue temperature.

It should be noted that, it is easy to think that the energy is sequentially superimposed by a plurality of optical pulse trains or by a plurality of sub-pulses, and therefore the focus of the following discussion is not focused on this. Further, in one optical burst, what needs to be demonstrated is the association of the N-1 th sub-burst with the N-th sub-burst and the benefits provided by each other.

In some embodiments, both N and M are configured to be 2, i.e., the optical pulse train within one photoperiod may be referred to as a "four pulse," which is configured to continuously output 2 sub-pulse trains, each having 2 sub-pulses. It should be noted that the four sub-pulses consisting of two sub-pulse trains are not to be understood as simply the output of a continuous pulse of light formed by the four sub-pulses, since the present application provides a limitation that the energy value of the mth sub-pulse at the N-1 th sub-pulse train is smaller than the energy value of the mth sub-pulse of the nth sub-pulse train. In other words, in a four-pulse embodiment, the energy value of the second sub-pulse is defined to be smaller than the energy value of the fourth sub-pulse, which allows the first sub-pulse train to have a less noticeable energy difference from the third sub-pulse after the energy is released, which has proved to be beneficial for the somatosensory differences of the user.

Fig. 12 shows a pulse diagram in which "six pulses" are performed in one photoperiod. In the illustration, N is 2 and m is 3, which is configured to output two sub-bursts in succession, each having three sub-pulses therein, wherein the third sub-pulse has an energy value that is less than the energy value of the sixth sub-pulse. In some embodiments, the six pulses have pulse widths of 0.4ms, 0.5ms, 2ms, 0.4ms, 0.5ms, and 6ms in sequence, with the pulse spacing in the first sub-pulse train 810 being 0.5s and 0.6s, respectively, and the pulse spacing in the second sub-pulse train 820 being 0.5s and 0.6s, respectively. It is noted that the definition of these sub-pulses as a plurality of sub-bursts is due to the sub-burst interval being provided between two adjacent sub-bursts, the sub-burst interval having a duration which is more significantly different from the pulse interval, which is not a negligible difference from the pulse interval of the six sub-pulse succession. In particular, a more pronounced sub-burst interval may be used to provide a user with a greater duration of reduction in skin temperature after undergoing the energy release of the first sub-burst to ensure that the skin temperature is always within the skin damage threshold, while the target tissue temperature may still remain at a relatively desirable cumulative value, which allows the target tissue to achieve a desired temperature after energy integration through multiple sub-bursts while also remaining below the desirable temperature, resulting in a better non-inductive use experience. In some embodiments, the sub-burst interval is greater than 1s in duration. More importantly, based on the usage habits of the user and the effects of the user, it is more desirable for such light pulse devices to achieve the desired hair removal and/or skin rejuvenation purposes in one light cycle, which places more stringent design requirements on the use of the device where the energy is released at one time and the user is less felt.

The benefits of the duration of the sub-burst interval, and the benefits of the energy value of the mth sub-pulse of the N-1 th sub-burst being less than the energy value of the mth sub-pulse of the N-th sub-burst, are more fully described below.

Fig. 13 shows a graph comparing the temperature profile of a single pulse used in the prior art with that of six pulses of the present application for the purpose of achieving the same target tissue temperature. Before interpreting the temperature profile versus the graph, it is necessary to first understand the concept that medical cosmetology involves "TRT (Thermal Relaxation Time )", which refers to the time required for the target tissue to dissipate half of its own absorbed heat, in theory, the pulse width of each sub-pulse and the pulse interval between two adjacent sub-pulses in the optical pulse train need to be greater than the skin TRT and less than the target tissue TRT, so as to ensure that the output energy is fully absorbed by the target tissue without dissipating heat outwards, and that the skin has enough time to dissipate heat to avoid negative body sensations (e.g., stinging and/or burning) caused by heat accumulation. Therefore, based on the concept of TRT and the above-mentioned requirement for more stringent design for the disposable and less sensitive use of energy, a scheme of setting a plurality of optical pulse trains in one optical period and having a sub-pulse train interval with a preset duration is proposed.

It can be seen in the illustration that a single pulse can cause the target tissue temperature to rise to the desired target temperature after a single pulse of pulsed light of all desired energy values is released at once, but accompanied by a linear rise in skin temperature and eventually exceeding the skin damage threshold. Generally, when the ambient temperature approaches the human body temperature (36-37 ℃), the skin is slightly stuffy or sticky, low-temperature scalding is likely to occur when the contacted heat source exceeds 44 ℃, progressive tissue damage is caused when the contact is performed for a long time in the temperature range of 45-60 ℃, and skin damage (such as red swelling, stinging and the like) is caused when the contact is performed for a short time above 50 ℃. Thus, the form of pulsed light release by a single pulse, or providing one sub-pulse with high energy in one pulse train, is not acceptable here.

As an improvement to address the increase in skin temperature in single pulse applications, the illustration provides that the six pulse embodiment can provide an energy accumulation of the target tissue temperature after the first sub-pulse train is released and ensure that the skin temperature is within the skin damage threshold, further providing a sub-pulse train interval having a duration of T2 (T2 >1 s) after the energy of the first sub-pulse train is released, the duration T2 of the sub-pulse train interval being significantly greater than the duration T1 of the pulse interval between sub-pulses, which provides a longer skin temperature cool down time for entering the next sub-pulse train. Since the target tissue temperature also decreases with the duration of T2, the energy value of the Mth sub-pulse defining the N-1 th sub-pulse train is less than the Mth sub-pulse energy value of the N-th sub-pulse train, which allows the desired target tissue temperature to be achieved by the temperature increase of the N-th sub-pulse train energy release even after the N-1 th sub-pulse train experiences a target tissue temperature decrease of T2 duration. More specifically, the skin temperature has a faster cool down rate than the target tissue temperature during the same interval period, and thus, during the T2 period of the sub-burst interval, the skin temperature may be expected to have more temperature loss and the target tissue temperature may have relatively less temperature loss.

As a comparative example, fig. 14A provides a comparative illustration of the third sub-pulse and sixth sub-pulse energy values approaching in "six pulses". It can be seen that when the third sub-pulse 803 has an energy value close to that of the sixth sub-pulse 806, and after the first sub-pulse is released, the skin temperature is already accompanied by the high energy of the third sub-pulse exceeding or being critical to the skin damage threshold, and in the actual use experience, the user will accompany the abnormality of the temperature body sensation (for example, the skin has uncomfortable heating sensation) in the middle of one photoperiod, and further, the target tissue temperature can reach the expected target value based on the energy accumulation of the first sub-pulse after the release of the second sub-pulse is completed, and the skin temperature further exceeds the skin damage threshold. This is an undesirable use experience.

Fig. 14B provides a comparative illustration of an excessively long burst interval duration of a "six pulse" neutron. As can be seen, the sub-burst interval duration T2 experienced is much greater than 1s after the first sub-burst is released, which results in a longer cooling duration for both the epidermis temperature and the target tissue temperature, and after the second sub-burst is released, the target tissue temperature is likewise reduced, although the epidermis temperature is within the skin damage threshold, and does not reach the desired temperature value. In the actual use experience, the user cannot easily perceive the abnormality of the skin body feeling in one light period, and the effectiveness of the light energy release is not ensured as well. Thus, in some embodiments, the sub-burst interval is set to 1 s≤T2≤1.5 s, i.e., T2 is set within a range that ensures the effectiveness of the light energy release.

Fig. 14C provides a comparative illustration of a "six pulse" neutron burst interval that is too short in duration. It can be seen that the sub-burst interval duration T2 experienced is much less than 1s after the first sub-burst is released, which results in a shorter cooling duration for both the skin temperature and the target tissue temperature, and after the second sub-burst is released, either the skin temperature or the target tissue temperature exceeds the desired value. In a practical use experience, the user may experience a tingling or burning sensation of the skin at the end of a light cycle.

In addition, according to the six pulse illustrations in fig. 12, 14A to 14C in order, four energy release patterns of the underarm portion were provided to six subjects by the light pulse device, respectively, and the results shown in fig. 15 were obtained. As shown in fig. 15, with the pulsed light embodiments according to fig. 12, 14A and 14C, the subjects were each provided an effective target tissue temperature (shown as v), but schemes 2 and 4, respectively, of fig. 14A and 14C, had more negative usage feedback, such as significant discomfort and intolerable pain. Scheme 3, which corresponds to fig. 14B, while having good feedback of more user's body feel, fails to reach the target tissue's desired temperature, which is considered an ineffective or inefficient energy release. The effectiveness of the user's body sensation or the target tissue temperature in accordance with scheme 1 is relatively well evaluated, and since the individual skin sensation is a subjective evaluation, the subject does not have a theoretically completely consistent evaluation result.

It will be appreciated that the number of sub-bursts may be increased or decreased depending on the superimposed value of the actual pulse energy requirement, and may be two sub-bursts or three or four sub-bursts, which allows a single photoperiod consisting of multiple sub-bursts to have a more flexible and variable energy release pattern. In some embodiments, the greater the number of sub-bursts, the smaller the corresponding amount of energy provided by each sub-burst can be accommodated, thereby bringing about a more energy gradient. For example, for a rough and hard skin area of hair, an embodiment may be performed in which three or even four sub-bursts are provided in one photoperiod, by increasing the energy gradient of the sub-bursts, on the one hand the effect of accumulating the target tissue temperature by energy superposition may be achieved, and on the other hand the user may be made more adaptable to changes by temperature increases, providing a comfortable use experience, but this may not be preferred in that the pulsed light output of one photoperiod has a perceptible extension, which also means that the number of sub-pulses and the number of sub-bursts need to be limited.

In some embodiments, in each sub-pulse train, there is a pulse interval T≥500 ms between the first sub-pulse and the second sub-pulse, and the duration T1 for charging in the pulse interval is≤300 ms. This means that the pulse intervals need not all be used to provide charging of the capacitance of the light pulse device, and that this embodiment may further optimize the charging and discharging pattern, thereby extending the lifetime of the capacitance, due to the multiple pulse light intervals in one photoperiod.

In some embodiments, the M-th sub-pulse of the N-1-th sub-pulse train has a first pulse energy value J1. Ltoreq.Mth sub-pulse of the N-th sub-pulse train has half the second pulse energy value J2, meaning J1 has a variation value of smaller energy gradient than the first sub-pulse of the N-th sub-pulse train, which may provide a more comfortable use experience for the user in light energy release.

In some embodiments, the sub-pulse interval T1 of two adjacent sub-pulses in each sub-pulse train satisfies 500 ms≤T1≤600ms, which provides a reasonable charging time for the capacitance of the light pulse device.

In some embodiments, the pulse energy value of the mth sub-pulse in each sub-pulse train is significantly greater than the pulse energy values of the other sub-pulses, which allows for the provision of a transition energy release at the end of each sub-pulse train, facilitating a temperature hold of the target tissue temperature in a short time without being released by an easy pulse interval.
