Specific embodiment

The representative embodiment illustrated in accompanying drawing is described below in detail.It should be appreciated that following description It is not intended as embodiment being limited to a preferred embodiment.On the contrary, it is intended to cover can be included in Replacement, modification and equivalent in the spirit and scope of described embodiment, such as appended right will Ask what is limited.

Below description relates generally to can be used to confirm that accessories apparatus relative to associated main frame The mechanism of the state of device, the associated host apparatus have the state consistency with accessories apparatus Mode of operation.More specifically, when accessories apparatus be have meet electronic installation size and During the protection cap of shape, the protection cap can have articulated section and be attached pivotally to the articulated section Capping.Capping can in one direction rotate so as to cover base in the closed configuration around articulated section Electronic installation is contacted on this.In turn, capping can be pivoted around hinge assembly along another direction To expose electronic installation in the open configuration.In one embodiment, when protection cap is detected as In closed configuration when, electronic installation can be operated in the case where closed-lid mode is closed；And work as protection cap quilt It is detected as in when opening configuration, electronic installation can be operated in the case where cover mold formula is opened.Protection cap Some aspects to electronic installation can be provided（Such as display）Protection, while lifted electricity The overall appearance and sensation of sub-device.Protection cap can at least include articulated section.Articulated section can be with Using magnetic attachment structure, magnetic is attached to electronic installation.Articulated section is pivotably connected to capping, The capping can be placed in the parts to be protected of electronic installation.Protection cap can include can be with electricity The electronic circuit or other elements of the electronic component cooperation in sub-device（It is passive or active）. Used as a part for the cooperation, signal can be transmitted between protection cap and electronic installation, these Signal can be used for changing operation, the electronic circuit of protection cap or other elements of electronic installation Operation, etc..

Electronic installation can include magnetometer circuit, and it is outside that the magnetometer circuit can be used to detection The directionality size in magnetic field.At this point, magnetometer can serve as being set to indicate that outside magnetic The orientation of field（directional bearing）With the compass of size.As such, it is possible to be inferred to electricity Orientation of the sub-device relative to external magnetic field（directional heading）.For example, outside is worked as When magnetic field is substantially magnetic field of the earth, onboard compass can be provided to electronic installation relative to the earth The instruction in the orientation of magnetic pole.In one embodiment, protection cap includes the envelope with magnetic element Lid.Magnetic element can include for magnetic attachment magnetic element and for triggering electronic installation in Hall effect（HFX）The magnetic element of sensor.In this case, it is possible to using onboard Compass come be based on magnetic element to onboard compass impact detection capping presence.

For example, onboard compass can be based on the first static magnetic deflection（Also referred to as Hard Magnetic skew）Inspection Measure capping and electronic installation is attached to by magnetic.First static magnetic deflection can be based on the envelope of protection cap The included presence for triggering the magnetic element of HFX sensors and attached for magnetic in lid Connect the presence of the magnetic element of capping and electronic installation.In another embodiment, compass can be examined Survey when capping around hinge assembly when pivoting with magnetic element motion dynamic magnetic potential Move.Can determine whether capping is in motion shape relative to onboard compass using dynamic magnetic displacement State.In one embodiment, can be according to the data from accelerometer and gyroscope real-time reception To infer the relative displacement of capping and electronic installation.Data from accelerometer and gyroscope can With relevant with the spatial orientation of electronic installation.Can be using the spatial orientation data and from onboard The magnetic reading of compass to determine capping in magnetic element whether transporting relative to electronic installation It is dynamic, to provide the instruction that capping is rotating around the pivotal line of hinge assembly.

In one embodiment, electronic installation can have touch sensitive surface, and the touch is sensitive Surface can to being attached to protection cap near protection cap internal layer at multiple conducting elements make Reaction.When protection cap is attached to electronic installation by magnetic, the plurality of conducting element can be connect Ground.In one embodiment, conducting element can be by predetermined thus be discernible pattern cloth Put.So, when the internal layer of protection cap includes the element that can be interacted with touch sensitive surface, These elements can be positioned in a pre-determined pattern, to help electronic installation to detect the present bit of protection cap Put.For example, in one embodiment, touch sensitive surface can be in nature it is capacitive, In this case, the embedded components in protection cap can be by conductive material（Such as aluminium etc Metal）Formed.Conducting element can be grounded, so as to increase by capacitive touch-sensitive surface with The capacitive signals noise ratio of the signal that the interaction between capacitive character embedded components is generated.

Magnetic element in closure portion can be interacted with the magnetosensitive circuit being attached in electronic installation. In one embodiment, magnetosensitive circuit can be in the form of HFX sensors, the HFX sensings Device can be detected by the external of the magnetic element offer in protection cap（extrinsic）Magnetic field is deposited .It should be noted, however, that in order to trigger HFX sensors, detected magnetic field must make HFX sensor saturations.So, the offer of HFX sensors is be provided electricity is sealed to protection cap The possibility that the mistake of sub-device is indicated.For example, the relative weak magnetic being associated with magnetic field of the earth Field intensity is insufficient to allow HFX sensors saturation and triggers the mistake to protection cap state and indicate.

When HFX sensors are exposed to saturation magnetic field（That is, with being enough to make HFX sensor saturations Magnetic field intensity magnetic field）When, HFX sensors can be by generating binary system（That is, ON/OFF）Signal to the saturation magnetic field responding.（In the lid state instruction for reducing mistake Possibility beyond,）One of advantage using HFX sensors is needed for operation HFX sensors Amount of power it is relatively small, therefore will not on the electronic device cause excessive power consumption.Any In the case of, when HFX sensors are exposed to saturation magnetic field, HFX sensors can send signal. The signal can be received by processing unit, and be used to change the mode of operation of electronic installation.No Cross, it should be noted that, it is possible to use any suitable as HFX sensors adjunctively or alternatively Sensing device further is detecting state of the protection cap relative to electronic installation.It is, for example possible to use magnetic strength Meter（A kind of its form can serve as compass）To replace HFX sensors.With HFX sensor phases Than, magnetometer is more sensitive to exterior magnetic field, therefore by by providing expression exterior magnetic field more Continuously（Simulation）Signal being responded, so as to need bigger amount of power.Therefore, Can be dynamic by magnetometer detection by periodically sampling to the signal from magnetometer State magnetic acitvity（For example, the relative motion of magnetometer and magnetic source is indicated）.It is, for example possible to use The data sampled to provide protection cap in magnetic element relative to the magnetometer in electronic installation Relative position.

Therefore, protection cap can include the magnetic element of such as permanent magnet, the magnetic of the magnetic element Field can make HFX sensors generate signal.Magnetic element can be placed on this in protection cap The position of sample, i.e. the position is placed on the surface of electronic installation or close electronic installation in lid HFX sensors are triggered during surface and generates signal.The signal can indicate protection cap be in relative to The precalculated position of electronic installation, the precalculated position can cause changing for the mode of operation of electronic installation Become.For example, in the case of the close HFX sensors in the part with magnetic element of protection cap, From the magnetic field of magnetic element HFX sensors can be made to generate signal.Then the letter can be used Number mode of operation is changed to be capped consistent state with a part for electronic installation.Example Such as, when electronic installation includes display, protection cap can be used for covering display, therefore make Display not may be viewed by, such that it is able to disable display.On the other hand, having when protection cap The part of magnetic element is removed and HFX sensors is no longer made to the magnetic field of magnetic element When going out the position of response, HFX sensors can then generate another signal.Another signal can be with Electronic equipment is caused to enter uncovered with least a portion of display and may be viewed by being thus able to Show the consistent another different mode of operation of vision content.

However, HFX sensors can be by any magnetic field for being strong enough that HFX sensor saturations Triggering, the mistake that thus may provide the presence to protection cap is indicated.Therefore, in order to avoid this Plant mistake to indicate, when HFX sensors are triggered, additional sensor can be inquired, so as to Instruction of the protection cap provided by HFX sensors in closed configuration is provided.In one embodiment In, trigger event of the indicating cover at HFX sensors in closed configuration fills can also electronics Put at least another sensor of inquiry, the closed configuration indicated by HFX sensors for confirmation.

In one embodiment, electronic installation can inquire ambient light sensor（ALS）.ALS Photosensitive circuit can be included（Such as photodiode）, the photosensitive circuit can be to different incidence Light（Typical form is ambient light）Level responds.In one embodiment, ALS can To detect ambient light.However, ALS can be configured in many ways to detecting ambient light Responded.For example, as long as ALS can be detected than predetermined by the photosensitive circuit in ALS The big amount of ambient light of amount of ambient light（That is, ambient light intensity）It is provided with signal to be responded. In other words, threshold value amount of ambient light can be the threshold level of regulation.For example, the threshold value of " x " lumen Amount can be represented be in the consistent amount of ambient light of closed configuration with protection cap, wherein, it is worth " x " Take into account the light leak into from the edge of protection cap.Certainly, threshold value amount of ambient light can be set It is considered as suitable amount for any.For example, it is in bright light environments in electronic installation（It is such as white My god）In some cases, light leak amount higher than the expected light leak amount under conditions of darker may be obtained It is many.Therefore, the light leak amount along protection cap edge may be much bigger, matches somebody with somebody in closure with protection cap Putting consistent threshold value light quantity can increase to take into account the fact.

In another embodiment, threshold quantity can be with the ring detected by the photosensitive circuit in ALS The differential variation of border light is consistent.For example, bright light environments are in electronic installation（Such as daytime Outdoor）In the case of, when protection cap is in fact closed, it is also possible to have sizable leakage Light quantity.However, in order to reduce the uncertainty related to real how many light leak, ALS can be with It is configured to provide letter based on the differential variation of the light quantity detected by the photosensitive circuit in ALS Number.For example, when protection cap is opened, ALS can be detected by " y₁" light quantity that represents of lumen. However, when protection cap is closed, the light quantity detected by the photosensitive circuit in ALS can be from " y₁” Lumen is changed into " y₂" lumen.Only in the difference of the light quantity for detecting（That is, Δ y=abs (y₁–y₂)） In the case of predetermined value, ALS can just be provided and be indicated protection cap in the suitable of closed configuration Signal.The advantage of this method is resided in the fact that：Light leak value is difficult to infer, therefore, pass through The change of clearly defined detected ambient light is depended on, can be obtained to protection cap relative to electricity The instruction of the more accurate and robust of the state of sub-device.

Therefore, by using ALS, electronic installation can confirm by HFX sensors provide it is right The instruction of the state of protection cap.So, if ALS is by detecting amount of ambient light and protection cap Consistent in closed configuration and confirm the instruction from HFX sensors, then electronic installation can be with Receive the instruction from HFX sensors, and correspondingly change the mode of operation of electronic installation.So And, if letter of the amount of ambient light with the instruction protection cap from HFX sensors in closed configuration It is number inconsistent, then electronic installation can inquire another sensor so as to obtain to be used to assessing from Another data point of the signal of HFX sensors, or more simply, can completely ignore and From the instruction of HFX sensors, it is hereby assumed that lid is not completely covered electronic installation, therefore, electronics The mode of operation of device will not be changed to be completely covered consistent operation shape with electronic installation State.However, if ALS detects the light quantity for confirming the instruction from hall effect sensor, Then electronic installation can receive from HFX sensors with regard to protection cap in closed configuration Indicate, it is possible to thus responded accordingly.

In another embodiment, camera can be activated, and the image captured based on camera Type, camera can be used to confirm the instruction being closed with regard to lid that HFX sensors are provided.Example Such as, when the cover is closed, camera can capture basic black（Or low-down lumen value） Image.If however, electronic installation is located at dark situation（Such as dark room, at night And there are little or moonless or other external light sources outdoors, etc.）In, it is only Some exterior lightings（Such as from display）Foot for capture images can be provided for camera Enough illuminations（For example, in terminal use on the face）.In one embodiment, the image for being captured Can be characterized with overall lumen value or lumen histogram, it is to close completely that this may be used to determine lid Or part closes.For example, even if lid is fully closed, some light leaks are also had, this can be with It is captured by a camera, so as to cause the capture images of low lumen.However, in another embodiment, Camera can be adjusted by this way, i.e. unless had on the image capture apparatus in camera Enough light, otherwise camera will not be based on the light leak specification of such as regulation and record image.However, If camera captures image, by the overall lumen value for assessing captured image（For example, Less than threshold value lumen value）, the position of protection cap can be estimated, and using estimated protection cap Position is confirming（Or do not confirm）From the instruction of HFX sensors.

In another embodiment, it is possible to use form be onboard compass magnetometer come detect with it is embedding Enter the magnetic element in protection cap to be located at HFX sensors or neighbouring correct position phase one The presence of the Hard Magnetic skew of cause.In this embodiment it is possible to using the presence of Hard Magnetic skew come really Recognize the instruction with regard to closing lid state from HFX sensors.On the other hand, electronic installation can The shape with regard to protection cap from HFX sensors is judged with not existing of being offset using Hard Magnetic The misregister of state, thus can be ignored, or other actions can be taken, such as inquire Another sensor.

It shall also be noted that the magnetic material that protection cap includes may affect magnetometer（It is such as onboard Compass）Performance.Especially, the basic operation of onboard compass（Being implemented as can be by processor Or the instruction that other appropriate circuitries are performed）Because of the magnetic material in protection cap presence and It is modified.Especially, the motion of protection cap may be detected as magnetic field intensity and side by onboard compass To change, this can cause " mistake " because onboard compass will be based on protection cap change in location And experience dynamic deflection.For example, it is onboard when lid is changed into closed configuration from opening configuration Dynamic deflection at compass may increase because of following facts：Magnetic element in protection cap is Magnetometer is moved close to, therefore causes the bigger deviant of onboard compass reading（Certainly, in lid State from closure be changed into open when, situation is just contrary）.

May be by caused by the change in location of magnetic element in protection cap, onboard compass experienced Peak excursion or the difference of compass azimuth be the Magnetic Sensor that is associated with onboard compass in protection The amplitude change in the magnetic field that detects during the change in location of lid and the horizontal intensity of external magnetic field Function.In order to by protection cap（More specifically, the magnetic element in protection cap）Motion The skew for causing is compensated, and onboard compass can utilize the magnetic for being able to detect that onboard compass The maximum change of amplitude is turned to the function of change of lid position this model.So, by making With by the maximum model for becoming the function for being turned to lid position of magnetic field amplitude and using external magnetic field Horizontal component amplitude current estimation, electronic installation can be estimated may be relative by protection cap The maximum change of the compass azimuth caused in the relative position change of electronic installation.

Correspondingly, can be combined with compass with reference to accelerometer in an electronic and gyroscope Use to assess the dynamic magnetic variation characteristic of detected external magnetic field（signature）.Plus Speedometer and gyroscope can in real time provide locus and the rotation of electronic installation, and compass can To provide the instruction with regard to external magnetic field change in real time.Accelerometer and gyroscope and compass Reading can be used together, and the model with magnetic element relative to the motion of electronic installation is carried out Compare, thus there is a possibility that and relative to electronic installation motion for assessing lid（It is logical Cross compass）.
