Description

The present invention relates to an interactive aerosol delivery system.

background

The "Background" description provided herein is intended to present the contents of this disclosure as a whole. The work of the inventors named herein to the extent described in this Background section, as well as aspects of this description that may not otherwise qualify as prior art at the time of filing, are not admitted explicitly or by implication as prior art to this disclosure.

Aerosol delivery systems are popular among users because they allow convenient, on-demand delivery of an active ingredient (such as nicotine) to the user.

As an example of an aerosol delivery system, an electronic cigarette (e-cigarette) generally contains a reservoir of feedstock liquid, typically containing a formulation including nicotine, from which an aerosol is generated, for example by thermal evaporation. Thus, an aerosol source for an aerosol delivery system may comprise a heater having a heating element arranged to receive the feedstock liquid from the reservoir, for example by wicking/capillary action. Similarly, other raw materials, such as botanicals or gels containing active ingredients and/or flavorings, may be heated to produce an aerosol. Thus, more generally, an e-cigarette may be considered to contain or receive a payload for thermal evaporation.

When a user inhales on the device, power is applied to a heating element, vaporizing an aerosol source (a portion of the payload) adjacent the heating element to generate an aerosol for inhalation by the user. Such devices typically include one or more air inlet holes located away from the mouthpiece end of the system. When a user inhales on a mouthpiece connected to the mouthpiece end of the system, air is drawn through the inlet holes and over the aerosol source. A flow path connects the aerosol source to an opening in the mouthpiece, such that air drawn over the aerosol source travels along the flow path to the mouthpiece opening, entraining a portion of the aerosol from the aerosol source. The air carrying the aerosol exits the aerosol delivery system through the mouthpiece opening and is inhaled by the user.

Typically, when a user inhales/puffs on the device, current is supplied to the heater, e.g., a resistive heating element. Typically, current is supplied to the heater, e.g., in response to activation of an airflow sensor along the flow path as the user inhales/puffs/puffs, or in response to activation of a button by the user. Heat generated by the heating element is used to vaporize the formulation. The released vapor mixes with air drawn through the device by the puffing consumer to form an aerosol. Alternatively or additionally, the heating element is used to heat, typically non-combustibly, a botanical substance such as tobacco, to release its active ingredient as a vapor/aerosol.

Reliable, efficient, and/or timely operation of such aerosol delivery systems can benefit from appropriately responding to the manner in which a user interacts with such systems.

The present invention emerged from this context.

Description of the embodiments

An interactive aerosol delivery system is disclosed. In the following description, a number of specific details are presented to provide a thorough understanding of the embodiments of the present disclosure. However, it will be apparent to one of ordinary skill in the art that these specific details are not required to practice the embodiments of the present disclosure. Conversely, specific details known to one of ordinary skill in the art are omitted for purposes of clarity.

The term "interactive aerosol delivery system" or, similarly, "delivery device" can encompass systems that deliver at least one substance to a user, including non-combustion aerosol delivery systems that release compounds from aerosol-generating materials without burning the aerosol-generating materials, such as electronic cigarettes, tobacco heating products, and combination systems that use a combination of aerosol-generating materials to generate an aerosol, as well as non-aerosol delivery systems that deliver at least one substance to a user orally, nasally, transdermally, or otherwise, without forming an aerosol, including, but not limited to, oral products such as lozenges, gums, patches, articles containing inhalable powders, and oral tobacco, including snus or snuff, where the at least one substance may or may not contain nicotine.

The substance to be delivered may be an aerosol-generating material or a material that is not intended to be aerosolized. Where appropriate, either material may include one or more active ingredients, one or more flavorings, one or more aerosol-forming materials, and/or one or more other functional materials.

Currently, the most common example of such a delivery device or aerosol delivery system (e.g., a non-combustion aerosol delivery system) is an electronic vapor delivery system (EVPS), such as an e-cigarette. Throughout the following description, the term "e-cigarette" is sometimes used, but this term can be used interchangeably with delivery device or aerosol delivery system, unless otherwise noted or the context indicates otherwise. Similarly, the terms "vapor" and "aerosol" are referred to interchangeably herein.

Generally, the electronic vapor/aerosol delivery system may be an electronic cigarette, also known as a vaping device or electronic nicotine delivery device (END), although it should be noted that the presence of nicotine in the aerosol-generating (e.g., aerosolizable) material is not a requirement. In some embodiments, the non-combustion aerosol delivery system is a tobacco heating system, also known as a non-combustion heating system. One example of such a system is a tobacco heating system. In some embodiments, the non-combustion aerosol delivery system is a combined system that generates an aerosol using a combination of aerosol-generating materials, one or more of which may be heated. Each of the aerosol-generating materials may be, for example, in solid, liquid, or gel form, and may or may not include nicotine. In some embodiments, the combined system includes a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material may include, for example, tobacco or a non-tobacco product. Meanwhile, in some embodiments, the non-combustion aerosol delivery system generates a vapor/aerosol from one or more such aerosol-generating materials.

Typically, a non-combustion aerosol delivery system may comprise a non-combustion aerosol delivery device and an article (otherwise referred to as a consumable) for use with the non-combustion aerosol delivery system. However, it is envisioned that an article with a means for powering an aerosol generating component (e.g., an aerosol generator such as a heater, a vibrating mesh, etc.) may itself form a non-combustion aerosol delivery system. In one embodiment, the non-combustion aerosol delivery device may comprise a power source and a controller. The power source may be a power source or a heat generating power source. In one embodiment, the heat generating power source comprises a carbon substrate, where electricity may be applied to the carbon substrate to disperse power in the form of heat to an aerosolizable or heat transfer material in proximity to the heat generating power source. In one embodiment, a power source, such as a heat generating power source, is provided within the article to form a non-combustion aerosol delivery. In one embodiment, an article for use with a non-combustion aerosol delivery device may include an aerosolizable material.

In some embodiments, the aerosol generating component is a heater capable of interacting with the aerosolizable material to liberate one or more volatile substances from the aerosolizable material to form an aerosol. In one embodiment, the aerosol generating component is capable of generating an aerosol from the aerosolizable material without applying heat. For example, the aerosol generating component may be capable of generating an aerosol from the aerosolizable material without applying heat to the aerosolizable material, e.g., via one or more of vibrational, mechanical, pressurized, or electrostatic means.

In some embodiments, the aerosolizable material can include an active material, an aerosol-forming material, and optionally one or more functional materials. The active material can include nicotine (optionally included in tobacco or a tobacco derivative), or one or more other non-olfactory bioactive materials. A non-olfactory bioactive material is a material included in the aerosolizable material to achieve a physiological response other than olfactory perception. The aerosol-forming material can include one or more of glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, mesoerythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixture, benzyl benzoate, benzyl phenylacetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. The one or more functional materials may include one or more of a fragrance, a carrier, a pH adjuster, a stabilizer, and/or an antioxidant.

In some embodiments, an article for use with a non-combustion aerosol delivery device can include an aerosolizable material or an area for receiving an aerosolizable material. In one embodiment, an article for use with a non-combustion aerosol delivery device can include a mouthpiece. The area for receiving an aerosolizable material can be a storage area for storing the aerosolizable material. For example, the storage area can be a reservoir. In one embodiment, the area for receiving an aerosolizable material can be separate from the aerosol generation area or can be combined with the aerosol generation area.

Referring now to the drawings, in which like reference numbers refer to identical or corresponding parts throughout the several views, FIG. 1 is a schematic diagram of a vapor/aerosol delivery system, such as an e-cigarette 10 (not to scale), providing a non-limiting example of a delivery device according to several embodiments of the present disclosure.

The e-cigarette has a generally cylindrical shape, extends along a longitudinal axis indicated by dashed line LA, and comprises two main components: a body 20 and a cartomizer 30. The cartomizer includes an internal chamber that contains a reservoir of payload, such as a liquid containing nicotine, a vaporizer (e.g., a heater), and a mouthpiece 35. Hereinafter, references to "nicotine" are understood to be merely exemplary and can be replaced with any suitable active ingredient. Hereinafter, references to "liquid" as the payload are understood to be merely exemplary and can be replaced with any suitable payload, such as botanical matter (e.g., tobacco that is heated in a non-combustible manner) or a gel containing an active ingredient and/or flavoring. The reservoir can be a foam matrix or any other structure for holding the liquid until the time required for delivery to the vaporizer. In the case of a liquid/flowing payload, the vaporizer is for vaporizing the liquid, and the cartomizer 30 can further include a wick or similar mechanism for transporting a small amount of liquid from the reservoir to the vaporizer or a nearby point of evaporation. Below, a heater is used as a specific example of a vaporizer. However, it will be understood that other forms of vaporizers (e.g., those that utilize ultrasound) can also be used, and that the type of vaporizer used can depend on the type of payload to be vaporized.

The body 20 includes a rechargeable cell or battery for providing power to the e-cigarette 10 and a circuit board for generally controlling the e-cigarette. When the heater receives power from the battery, as controlled by the circuit board, it vaporizes the liquid, and the vapor is then inhaled by the user through the mouthpiece 35. In some specific embodiments, the body further includes a manual activation device 265, such as a button, switch, or touch sensor, located on the exterior of the body.

Although the body 20 and the cartomizer 30 can be removable from each other by separating them in a direction parallel to the longitudinal axis LA shown in FIG. 1, when the device 10 is in use, they are joined together by connections shown diagrammatically as 25A and 25B in FIG. 1 to provide mechanical and electrical connectivity between the body 20 and the cartomizer 30. The electrical connector 25B of the body 20 used to connect to the cartomizer 30 also serves as a socket for connecting a charging device (not shown) when the body 20 is removed from the cartomizer 30. The other end of the charging device can be plugged into a USB socket to recharge the battery in the body 20 of the e-cigarette 10. In other implementations, a cable can be provided for direct connection between the electrical connector 25B of the body 20 and the USB socket.

The e-cigarette 10 includes one or more holes (not shown in FIG. 1) for air inlet. These holes connect to an air passageway that passes through the e-cigarette 10 and leads to the mouthpiece 35. When the user inhales through the mouthpiece 35, air is drawn into this air passageway through one or more air inlet holes suitably located on the exterior of the e-cigarette. When the heater is activated to vaporize the nicotine from the cartridge, the airflow passes through and mixes with the generated vapor, and the combination of airflow and generated vapor then exits the mouthpiece 35 for inhalation by the user. Except for one-time use devices, when the liquid supply is exhausted, the cartomizer 30 can be removed from the body 20 and disposed of (or replaced with another cartomizer, if desired).

It will be appreciated that the e-cigarette 10 shown in FIG. 1 is presented as an example, and various other implementations may be employed. For example, in some embodiments, the cartomizer 30 is provided as two separable components: a cartridge with a liquid reservoir and a mouthpiece (which can be replaced when the liquid from the reservoir is depleted), and a vaporizer with a heater (which is generally retained). As another example, the charging mechanism may be connected to an additional or alternative power source, such as a car cigarette lighter.

2 is a schematic (simplified) diagram of the body 20 of the e-cigarette 10 of FIG. 1 according to some embodiments of the present disclosure. FIG. 2 can generally be considered to be a cross-section in a plane passing through the longitudinal axis LA of the e-cigarette 10. It should be noted that various components and details of the body, such as wiring and more complex shapes, have been omitted from FIG. 2 for reasons of clarity.

The main body 20 includes a battery or cell 210 for powering the e-cigarette 10 in response to activation by a user of the device. In addition, the main body 20 includes a control unit 205, for example a chip such as an application specific integrated circuit (ASIC) or microcontroller, for controlling the e-cigarette 10. The microcontroller or ASIC includes a CPU or microprocessor. The operation of the CPU and other electronic components is generally controlled, at least in part, by a software program running on the CPU (or other components). Such software programs can be stored in non-volatile memory such as ROM, which can be integrated into the microcontroller itself or can be provided as a separate component. The CPU can access the ROM to load and execute individual software programs as needed. The microcontroller also contains appropriate communication interfaces (and control software) for communicating with other devices in the main body 10 as appropriate.

The body 20 further includes a cap 225 for sealing and protecting the distal end of the e-cigarette 10. Typically, an air inlet hole is provided in or near the cap 225 to allow air to enter the body 20 when the user inhales on the mouthpiece 35. The control unit or ASIC may be located at or near one end of the battery 210. In some embodiments, the ASIC is attached to a sensor unit 215 (or alternatively, the ASIC itself may include a sensor unit 215) to detect inhalations on the mouthpiece 35. An air path is provided from the air inlet through the e-cigarette, past the airflow sensor 215 and the heater (in the vaporizer or cartomizer 30) to the mouthpiece 35. Thus, when the user inhales on the mouthpiece of the e-cigarette, the CPU detects such inhalations based on information from the airflow sensor 215.

At the end of the body 20 opposite the cap 225, a connector 25B is provided for joining the body 20 to the cartomizer 30. The connector 25B provides mechanical and electrical connectivity between the body 20 and the cartomizer 30. The connector 25B includes a body connector 240 made of metal (in some embodiments, silver plated) to serve as one terminal for electrical connection (positive or negative) to the cartomizer 30. The connector 25B further includes an electrical contact 250 that provides a second terminal for electrical connection to the cartomizer 30 with the opposite polarity to the first terminal, i.e., the body connector 240. The electrical contact 250 is attached to a coil spring 255. When the body 20 is attached to the cartomizer 30, the connector 25A on the cartomizer 30 is pressed against the electrical contact 250 in such a way as to compress the coil spring axially, i.e., parallel to (aligned with) the longitudinal axis LA. Given the resilience of the spring 255, this compression biases the spring 255 to expand, which has the effect of pressing the electrical contact 250 firmly against the connector 25A of the cartomizer 30, thereby helping to ensure good electrical connectivity between the body 20 and the cartomizer 30. The body connector 240 and the electrical contact 250 are separated by a trestle 260 made of a non-conductor (such as plastic) to provide good insulation between these two electrical terminals. The trestle 260 is shaped to aid in the mutual mechanical engagement of the connectors 25A and 25B.

As mentioned above, a button 265 representative of the form of a manual activation device 265 may be located on the outer housing of the body 20. The button 265 may be implemented using any suitable mechanism operable to be manually activated by a user, such as, for example, a mechanical button or switch, a capacitive or resistive touch sensor, etc. It will also be appreciated that the manual activation device 265 may be located on the outer housing of the cartomizer 30 rather than on the outer housing of the body 20, in which case the manual activation device 265 may be attached to the ASIC via connections 25A, 25B. The button 265 may also be located on the end of the body 20 instead of (or in addition to) the cap 225.

3 is a schematic diagram of the cartomizer 30 of the e-cigarette 10 of FIG. 1 according to some embodiments of the present disclosure. FIG. 3 can be generally considered to be a cross-section in a plane passing through the longitudinal axis LA of the e-cigarette 10. It should be noted that various components and details of the cartomizer 30, such as wiring and more complex shapes, have been omitted from FIG. 3 for reasons of clarity.

The cartomizer 30 includes an air passage 355 that extends from the mouthpiece 35 to the connector 25A along the central (longitudinal) axis of the cartomizer 30 for joining the cartomizer 30 to the main body 20. A liquid reservoir 360 is provided around the air passage 335. The reservoir 360 can be implemented, for example, by providing cotton or foam soaked in liquid. The cartomizer 30 also includes a heater 365 that heats liquid from the reservoir 360 to produce vapor that exits the mouthpiece 35 through the air passage 355 in response to a user's puff on the e-cigarette 10. The heater 365 is powered through lines 366 and 367, which are connected to the opposite polarities (positive and negative, or vice versa) of the battery 210 of the main body 20 via the connector 25A (the wiring details between the power lines 366 and 367 and the connector 25A have been omitted from FIG. 3).

Connector 25A includes an inner electrode 375, which may be silver plated or made from any other suitable metal or conductive material. When cartomizer 30 is connected to body 20, inner electrode 375 contacts electrical contact 250 of body 20 to provide a first electrical path between cartomizer 30 and body 20. In particular, when connectors 25A and 25B are engaged, inner electrode 375 presses against electrical contact 250, compressing coil spring 255 and thereby helping to ensure good electrical contact between inner electrode 375 and electrical contact 250.

The inner electrode 375 is surrounded by an insulating ring 372, which can be made of plastic, rubber, silicone, or any other suitable material. The insulating ring is surrounded by a cartomizer connector 370, which can be silver plated or made of any other suitable metal or conductive material. When the cartomizer 30 is connected to the body 20, the cartomizer connector 370 contacts the body connector 240 of the body 20 to provide a second electrical path between the cartomizer 30 and the body 20. In other words, the inner electrode 375 and the cartomizer connector 370 act as positive and negative terminals (or vice versa) for appropriately supplying power from the battery 210 in the body 20 to the heater 365 in the cartomizer 30 via the supply lines 366 and 367.

The cartomizer connector 370 comprises two lugs or tabs 380A, 380B extending in opposite directions away from the longitudinal axis of the e-cigarette 10. These tabs are used to provide a bayonet fit with the body connector 240 for connecting the cartomizer 30 to the body 20. This bayonet fit provides a secure and robust connection between the cartomizer 30 and the body 20, such that the cartomizer and the body are held in a fixed position relative to each other with minimal rocking or bending, and the possibility of any accidental disconnection is very small. At the same time, the bayonet fit provides easy and rapid connection and disconnection by rotation after insertion for connection and removal after rotation (in the opposite direction) for disconnection. It will be appreciated that in other embodiments, different forms of connection can be used between the body 20 and the cartomizer 30, such as a snap fit or a threaded connection.

4 is a schematic diagram of certain details of the connector 25B at the end of the body 20 according to some embodiments of the present disclosure (although for clarity, most of the internal structure of the connector shown in FIG. 2, such as the trestle 260, is omitted). In particular, FIG. 4 shows the outer housing 201 of the body 20 having a generally cylindrical tube form. This outer housing 201 may comprise, for example, a metal inner tube and may have an outer covering, such as paper. The outer housing 201 may also comprise a manual activation device 265 (not shown in FIG. 4), such that the manual activation device 265 is easily accessible to a user.

The body connector 240 extends from this outer housing 201 of the body 20. The body connector 240 shown in FIG. 4 comprises two main parts: a shaft portion 241 in the shape of a hollow cylindrical tube sized to fit snugly inside the outer housing 201 of the body 20, and a lip portion 242 oriented radially outwardly away from the main longitudinal axis (LA) of the e-cigarette. If the shaft portion does not overlap the outer housing 201, a collar or sleeve 290 is provided to surround the shaft portion 241 of the body connector 240, the collar or sleeve 290 also being in the shape of a cylindrical tube. The collar 290 is held between the lip portion 242 of the body connector 240 and the outer housing 201 of the body, which together prevent movement of the collar 290 in the axial direction (i.e. parallel to the axis LA). However, the collar 290 is free to rotate around the shaft portion 241 (and thus also around the axis LA).

As mentioned above, the cap 225 includes an air inlet hole that allows air to flow when the user inhales on the mouthpiece 35. However, in some embodiments, the majority of the air that enters the device when the user inhales flows through the collar 290 and the body connector 240, as shown by the two arrows in FIG. 4.

5, an e-cigarette 10 (or, more generally, any delivery device described elsewhere herein) can operate within a broader delivery ecosystem 1, in which multiple devices can communicate with each other directly (as indicated by solid arrows) or indirectly (as indicated by dashed arrows).

5, an exemplary delivery device is shown in which an e-cigarette 10 can communicate directly (e.g., using Bluetooth® or Wifi Direct®) with one or more other classes of devices, including, but not limited to, a smartphone 100, a dock 200 (e.g., a home refilling and/or charging station), a vending machine 300, or a wearable 400. As noted above, these devices can cooperate in any suitable configuration to form a delivery system.

Alternatively or additionally, a delivery device, such as the e-cigarette 10, may indirectly communicate with one or more of these classes of devices via a network, such as the Internet 500, using, for example, Wi-Fi, short-range communications, wired links, or integrated mobile data methods. Again, as described above, these devices may thus cooperate in any suitable configuration to form a delivery system.

Alternatively or additionally, a delivery device, such as e-cigarette 10, can indirectly communicate with server 1000 via a network such as the Internet 500, itself by using e.g. WiFi, or via another device in the delivery ecosystem, for example by using Bluetooth or WiFi Direct to communicate with smartphone 100, dock 200, vending machine 300, or wearable 400, which then communicates with the server to relay the e-cigarette's communications or to report its communications with e-cigarette 10. Optionally, therefore, other devices in the delivery ecosystem, such as smartphones, docks, or point-of-sale/vending machines, can act as hubs for one or more delivery devices that only have short-range transmission capabilities. Such hubs can therefore extend the battery life of delivery devices that do not need to maintain ongoing WiFi or mobile data links. It will also be appreciated that different types of data may be transmitted at different levels of priority, for example data related to a user feedback system (such as user factor data or feedback behavior data as discussed herein) may be transmitted at a higher priority than more general usage statistics, or similarly, some user factor data related to shorter term variables (such as current physiological data) may be transmitted at a higher priority than user factor data related to longer term variables (such as current weather or day of the week). A non-limiting exemplary transmission scheme that allows for higher and lower priority transmission is LoRaWAN.

However, other classes of devices in the ecosystem, such as smartphones, docks, vending machines (or any other point of sale system), and/or wearables, may also communicate indirectly with the server 1000 via a network such as the Internet 500 to fulfill aspects of their own functionality or in lieu of a delivery system (e.g., as a relay or simultaneous processing unit). These devices may also communicate directly or indirectly with each other.

It will be appreciated that a delivery ecosystem may comprise multiple delivery devices (10), at least in part because, for example, a single user may own multiple devices (e.g., to easily switch between different active ingredients or fragrances) or because multiple users share the same delivery ecosystem (e.g., multiple users living in the same home may have their own phones or wearables while sharing a single charging dock). Optionally, such devices may also communicate, directly or indirectly, with each other and/or with devices in a shared delivery ecosystem and/or server.

6, in which features similar to those of FIG. 1 are similarly labeled, the aerosol delivery device can then comprise at least one wireless receiver 610 configured to receive wireless communication signals. This can comprise a Bluetooth® or Wifi® receiver operable to communicate with a companion device, such as a charging hub or indeed a user's phone or smartwatch, e.g., a closely associated device in the delivery ecosystem.

Alternatively, the receiver may be the same receiver as described above operating in a different mode, or may be a separate receiver.

As an alternative or in addition to at least one wireless receiver 610 in the aerosol delivery device, optionally at least one such wireless receiver 610 can be provided in a companion device in the delivery ecosystem, typically a device that would also accompany the user, such as a phone or smartwatch.

Thus, it will be appreciated that an aerosol delivery system (e.g., an aerosol delivery device, optionally operating in conjunction with one or more other devices in a delivery ecosystem, such as a phone or smartwatch) can receive wireless communication signals for use as follows:

Accordingly, in the embodiment of the present description, the aerosol delivery system 1 comprises an aerosol delivery device 10 and a wireless signal receiver 610 configured to receive a wireless communication signal.

The aerosol delivery system 1 also includes an identification processor (e.g., control unit 205) configured (e.g., by suitable software instructions) to store characterization data for identifying the received return wireless communication signal.

Similarly, the aerosol delivery system 1 also includes a correlation processor (e.g., control unit 205) configured (e.g., by suitable software instructions) to correlate a user behavior with identified recurrent wireless communication signals received within a predetermined time window for that user behavior, and a control processor (e.g., control unit 205) configured (e.g., by suitable software instructions) to modify one or more operating parameters of the aerosol delivery device related to the user behavior when one or more wireless communication signals previously correlated by the correlation processor with a particular user behavior are subsequently received by the wireless signal receiver and identified by the identification processor.

It will thus be appreciated that the aerosol delivery system correlates recurrent signals in the wireless environment with user behavior (e.g., in terms of interaction with and/or use of the delivery device) such that when one or more such signals are encountered again, the system can alter one or more aspects of its functionality in preparation for the expected correlated user behavior, thereby making the system more responsive to the user and more intuitive to use.

Optionally, in addition to the aerosol delivery device itself, the aerosol delivery system may include a companion device, such as the user's mobile phone or smartwatch, or any other device in the broader delivery ecosystem, such as a docking port.

In this case, the companion device may then optionally be equipped with a wireless signal receiver (in this case in addition to the wireless transceiver typically used to communicate with the aerosol delivery device itself, or such a transceiver operating in an alternative mode).

Similarly, the companion device may comprise one or more of the identification processor, correlation processor, and control processor, or any of these roles may be shared to any suitable degree between the aerosol delivery device and the companion device.

Thus, a correlation processor, which may have to perform cross-correlation between, for example, stored samples of the radio signal and the received radio signal, or the access identification or other metadata within the radio signal, may be based on the user's mobile phone, which is likely to have a larger battery and more powerful processor than the delivery device itself.

Similarly, the wireless signal receiver (which in practice may comprise a series of different wireless signal receivers) may be capable of receiving a wider number of types of wireless signals than the delivery device on a mobile phone, or in other words the delivery device may be made simpler (e.g. using only low energy Bluetooth) if it is able to utilise the existing wide range of wireless reception capabilities of a companion device such as a mobile phone.

In either case, the wireless capability range may include, for example, one or more of Wi-Fi, Bluetooth, short-range transmission (such as those used in contactless payment systems, card keys, etc.), inductive chargers (such as those used for wireless charging), radio frequency identification transmission (such as those found at security barriers in stores), digitally enhanced cordless telecommunications (e.g., cordless telephone signals), and picocells (e.g., indoor mobile cells).

Similarly, the wireless capabilities may optionally include conventional cellular signals. These may be easily detected by a companion device such as a telephone, but may also be detected by a suitable delivery device, e.g., a device equipped with a wireless data modem, for purposes of communicating with one or more remote services (such as those that may be provided by server 1000).

For a given wireless communication signal, the characterization data may include address data extracted from the received wireless communication signal (e.g., WiFi access point data, Bluetooth beacon, or handshake data, etc.). Similarly, the characterization data may include the transmission protocol of one or more received wireless communication signals (e.g., from a DECT phone or an inductive charger), the frequency of one or more received wireless communication signals (e.g., a carrier frequency such as 2.4 GHz or 5 GHz), and the variant of one or more received wireless communication signals.

Similarly, environmental effects on the wireless signal itself may form characterization data, e.g., the relative signal strength of one or more received wireless communication signals may indicate the layout of the current wireless environment and the user's location therein. Similarly, one or more delay propagation characteristics received in the communication signal (e.g., multiple reception paths due to reflections) may also be indicative of this environment. In particular, such reflections may indicate whether the device is indoors or outdoors (as well as any other characterization data, e.g., the presence of a particular device, such as a wireless printer, that may be expected to be indoors), and thus the control processor may optionally be configured to estimate whether the aerosol delivery device is indoors or outdoors based on the received wireless communication signals, and to modify one or more operating parameters of the aerosol delivery device in response thereto.

Optionally, the identification processor and/or correlation processor may ignore characterization signals that are common throughout the day or across multiple locations, as these are unlikely to correlate strongly with distinctive behavior. For example, during detection, while an inductive charger may indicate that a user is preparing to stop using the delivery device and therefore behave in a particular way, the Bluetooth signal itself may be ubiquitous and therefore not correlate strongly with a particular user behavior. In contrast, distinctive devices identified by Bluetooth signals may actually have a strong correlation with behavior, e.g., a wireless speaker at home may correlate strongly with a user who is relaxing and preparing to use the delivery device, and a wireless printer at work may correlate strongly with a user who does not interact with the delivery device at all.

As a result, the wireless communication signal may thus include a signal from a pre-associated device (e.g., a device that broadcasts identifying information as part of the wireless communication signal and can therefore be identified again), and the control processor may be configured to modify the operation of the aerosol delivery device in either the presence or absence of one or more such pre-associated devices. It is clear that this can be implemented as described above, i.e., using a correlation processor, with a clear and strong correlation between associated devices and user behavior. Alternatively or additionally, when an associated device is detected, a rule may be recorded by or for the control processor to simply implement the associated change(s) to one or more operating parameters.

Such a rule can be recorded when a correlation between the presence of an associated device and user behavior reaches a threshold level. The control processor can then refer to the rules list first to determine whether and how to make any changes in response to a detected wireless communication signal, and can revert to using the correlation processor only if a rule is not available.

The correlation processor itself may include any suitable correlation scheme. A common example of a correlation scheme is a machine learning system such as a neural network. In general, a suitable correlation scheme would take as input characterization data, described below, for identifying received return wireless communication signals, and target user behaviors, either directly sensed by the delivery device or other devices in the delivery ecosystem (e.g., detecting touch or changes in device orientation, which may be actions taken prior to use), or, by proxy, in terms of changes in the operating parameters of the aerosol delivery device caused by those user behaviors (e.g., when blowing on the delivery device, changing its settings, or interacting with the UI, or similar).

In practice, the input and target can occur contemporaneously or can be separated by a predetermined period of time, such as ±1, 5, or 10 minutes.

The wireless communication signal feature data is then input into the correlation system, which outputs values corresponding to expected targets. These can be used directly to vary one or more operating parameters (if the correlation system has been trained on such operating parameters as described above), or can be used to classify user behavior and vary one or more operating parameters in response to the classified user behavior.

As described elsewhere herein, optionally the location of the wireless signal may be important for correlation with user behavior, either in terms of absolute location or whether the wireless signal is associated with a location.

Accordingly, the aerosol delivery system may optionally be equipped with a location determining unit, for example a GPS location unit, which may be found in a companion device such as a mobile phone, but may also be integrated within the aerosol delivery device.

As described elsewhere herein, the resulting location information can be used to determine whether a given characterization data of a wireless communication signal is ubiquitous or rare, and therefore whether the correlation is low or high in significance for purposes of determining whether to modify the operating parameters of the aerosol delivery device if that characterization data occurs again.

It will also be apparent that the resulting location information can optionally be used in conjunction with the characterization data to make the correlation of wireless communication signals at that location substantially more significant.

Optionally, the control processor may also be configured to associate the received wireless communication signals with one or more determined locations, and thus only associate one or more user behaviors/uses of the aerosol delivery device with the determined locations. Thus, for example, if a user activates a wireless speaker at home periodically, but not all the time, the system may associate certain user behaviors with powering on the wireless speaker, but may optionally associate those certain user behaviors with the same location as the wireless speaker, even if the wireless speaker is not powered on.

It will be appreciated that similar multiple correlations can be implemented between wireless communication signal characterization data and time and/or date.

If a position determination unit is available, optionally the aerosol delivery system is configured to modify one or more operating parameters of the aerosol delivery system in response to the newly determined position.

In this case, the operating parameters may relate to going into a general default dormant or standby mode, or a default ready mode, provided that no uncorrelated wireless communication signals can be expected to be present at the new location. Alternatively or additionally, the operating parameters may relate to the situational awareness of the aerosol delivery system, particularly reception of wireless communication signals, for example, optionally increasing gain for one or more wireless reception modes to increase sensitivity to wireless signals, or transmitting a polling signal to prompt transmission of signals from nearby devices.

Similarly, the aerosol delivery system may be configured to modify one or more operating parameters of the aerosol delivery system in response to a newly encountered wireless environment. In other words, if a wireless signal or combination of wireless signals is new and there is no apparent pre-existing correlation between one or more signals and, for example, user behavior or changing parameters above a predefined threshold (e.g., if the correlator output does not strongly indicate user behavior or parameter changes in response to the detected signals), the system may similarly revert to a default dormant or standby mode, or a default ready mode, and/or similarly modify the situational awareness of the aerosol delivery system to, for example, query for new wireless communication signals (e.g., reply to a polling or handshake signal to obtain identification information, or increase gain to improve a wireless communication signal when received).

In response to one or more received return wireless communication signals, or one or more sets thereof, the control processor may be operable to optionally set a first activity state or a second activity state. The first activity state may be associated with a current or anticipated release by a user of the aerosol delivery device, and the second activity state may be associated with a current or anticipated engagement by a user of the aerosol activity device, the aerosol activity device optionally being of a specific type. These states may be considered to be respective classifications of one or more settings for one or more operating parameters of the aerosol delivery system.

Thus, generally, when compared to the second activity state, the first activity state has one or more of lower power requirements, fewer active functions, lower power settings for one or more functions, and alternative functions (e.g., typically lower alternative power and/or less intrusive functions, e.g., quieter alerts) compared to those for the second activity state.

For example, the first activity state may include one or more selected from the list consisting of displaying a first set of information, displaying a first level of information detail, lower duty cycle or lower power data transmission, lower duty cycle or lower power preheating, lower duty cycle or lower power lighting, and lower duty cycle or lower power situational awareness, where "lower" is lower than the second state. In contrast, for example, the second activity state may include one or more selected from the list consisting of displaying a second set of information (distinct from the first set of information or a superset of the first set of information), displaying a second higher level of information detail, higher duty cycle or higher power data transmission, higher duty cycle or higher power heating, higher duty cycle or higher power lighting, and higher duty cycle or higher power situational awareness, where "higher" is higher than the first state.

Thus, optionally, the first activity state may be characterized as one or more of a lower power state, a lower situational awareness state, a lower notification (e.g., notification to a user or companion device) state, a lower wakefulness state, a lower UI information state, a quieter state, a cooler state, etc., relative to the second state.

In the above example, a lower situational awareness state could mean a slower duty cycle for radio scanning, or less complex data analysis for the identification process or correlation processor, etc.

The first and second sets of information and levels of information detail, on the other hand, may relate to information related to different states and possible levels of user engagement with the device at that time.

Thus, for example, in a first state, the delivery device may appear completely off, or may only display (or periodically report to a companion device) its battery and payload status (e.g., e-liquid level), e.g., without backlighting. Meanwhile, in a second state, the delivery device may backlight the display and may include other more detailed information in the UI, such as the current payload flavor or strength, the current mode of operation, and may optionally preheat the heater to a pre-vaporization temperature and indicate that this has been achieved. Alternatively, operations such as preheating the heater (using a relatively large amount of power) may be performed only as part of a third state initiated by the user to directly physically interact with the delivery device, optionally in a manner specific to immediate use. Optionally, if such a third state is included, functionality in the second state may include active sensing for indicators of the third state.

Thus, optionally, the first state may be characterized as an inactive or standby state, the second state as an awake or ready state, and an optional third state as a ready or pre-use state.

The functionality distinguished by the first and second states may vary depending on the particular delivery device and/or any companion devices, the strength of the correlation between the received wireless communication signal and the user behavior and/or operational parameters, the type of user behavior and/or operational parameters associated with the received wireless communication signal, etc.

Thus, for example, a user behavior corresponding to playing with the aerosol delivery device may prompt one type of second activity state in which the user interface of the delivery device is backlit to provide more information, and a user behavior involving use of the aerosol delivery device may prompt another type of second activity state involving pre-heating the heater.

Referring now also to FIG. 7, a corresponding method of operating an aerosol delivery system includes:
A step s710 of receiving a wireless communication signal;
a step s720 of storing characterization data for identifying the received return wireless communication signal;
a step s730 of correlating the user behavior with identified recurring wireless communication signals received within a predefined time window for that user behavior (e.g., usage);
and when one or more wireless communication signals pre-correlated with a particular user behavior are then received and identified by the wireless signal receiver, step s740 of modifying one or more operating parameters of the aerosol delivery device related to that user behavior.

It will be apparent to one of ordinary skill in the art that variations of the above methods corresponding to the operation of the various embodiments of the apparatus described and claimed herein are considered to be within the scope of the present invention.

Conversely, such methods may be implemented in suitably configured conventional hardware, either by software instructions or by inclusion or substitution of dedicated hardware, an example of which is the delivery device of Figures 2 and 6, where it will be appreciated that the control unit 205 (or alternatively or additionally one or more processors within a broader delivery ecosystem) operates under suitable software instructions.

The required configuration of the existing parts of the conventional equivalent device may thus be implemented in the form of a computer program product including processor-implementable instructions stored on a non-transitory machine-readable medium, such as a floppy disk, optical disk, hard disk, solid-state disk, PROM, RAM, flash memory, or any combination of these or other storage media, or may be realized in hardware as an ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array), or other configurable circuit suitable for use in configuring the conventional equivalent device. Alternatively, such a computer program may be transmitted via data signals over a network, such as an Ethernet, a wireless network, the Internet, or any combination of these or other networks.

The above discussion discloses and describes merely exemplary embodiments of the present invention. As will be understood by those skilled in the art, the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Accordingly, the disclosure of the present invention is intended to be illustrative and not limiting of the scope of the present invention and other claims. The disclosure, including all readily discernible variations of the teachings herein, in part defines the scope of the claim terminology so as not to provide the subject matter of the invention to the public.
