Embodiment

The below describes illustrative exemplary embodiment in accompanying drawing in detail.Should be appreciated that following description is not intended to embodiment is limited to a preferred embodiment.On the contrary, be intended to contain can be included in described embodiment spirit and scope in replacement, revise and be equal to, as defined by the appended claims.

Below describe to relate generally to and can be used for confirming accessories apparatus with respect to the mechanism of the state of the host apparatus that is associated, this host apparatus that is associated has the mode of operation with the state consistency of accessories apparatus.More particularly, when accessories apparatus is when having the over cap of the size and dimension that meets electronic installation, this over cap can have the articulated section and be attached to pivotally the capping of this articulated section.Capping can be around the articulated section along a direction rotation so that be sealed on and basically contact electronic installation in closed configuration.Conversely, capping can be exposed electronic installation along another direction pivotable to open in configuration around hinge assembly.In one embodiment, when over cap is detected as when being in closed configuration, electronic installation can operate under the closing lid pattern; And open when configuration when over cap is detected as to be in, electronic installation can operate opening under the cover mold formula.Over cap can provide the protection to some aspect (such as display) of electronic installation, promotes simultaneously overall appearance and the sensation of electronic installation.Over cap can comprise the articulated section at least.The magnetic attachment structure can be used in the articulated section and magnetic is attached to electronic installation.The articulated section can pivotable be connected to capping, and this capping can be placed on the part that will protect of electronic installation.Over cap can comprise the electronic circuit that can cooperate with the electronic component in electronic installation or other element (passive or active).As the part of this cooperation, signal can transmit between over cap and electronic installation, and these signals can be used for revising operation, the electronic circuit of over cap or the operation of other element of electronic installation, etc.

Electronic installation can comprise the magnetometer circuit, and this magnetometer circuit can be used for detecting the directivity size of external magnetic field.In this, magnetometer can be as the compass of the orientation (directional bearing) that is set to indicate the external magnetic field and size.Like this, can infer that electronic installation is with respect to the orientation (directional heading) of external magnetic field.For example, when the external magnetic field was the magnetic field of the earth in fact, plate carried compass and can provide the indication of electronic installation with respect to the orientation of terrestrial magnetic pole.In one embodiment, over cap comprises the capping with magnetic element.Magnetic element can comprise for the attached magnetic element of magnetic and be used for triggering the magnetic element of Hall effect (HFX) sensor of electronic installation.In the case, can carry compass with plate and based on magnetic element, plate be carried the existence of the impact detection capping of compass.

For example, plate carries compass and can detect capping based on the first static-magnetic skew (also referred to as the Hard Magnetic skew) and be attached to electronic installation by magnetic.The first static-magnetic skew can the capping based on over cap in included being used for trigger the existence of magnetic element of HFX sensor and the existence that is used for the magnetic element of the attached capping of magnetic and electronic installation.In another embodiment, compass can detect when capping dynamic magnetic displacement along with the motion of magnetic element during around the rotation of the pivot of hinge assembly.Can determine whether capping is carried compass with respect to plate and be kept in motion with the dynamic magnetic displacement.In one embodiment, can be according to infer the relative displacement of capping and electronic installation from the data of accelerometer and the real-time reception of gyroscope.Can be relevant with the dimensional orientation of electronic installation from accelerometer and gyrostatic data.Can whether determine magnetic element in capping with respect to the electronic installation motion with these dimensional orientation data with from the magnetic reading that plate carries compass, to provide capping around the indication of the pivot axis rotation of hinge assembly.

In one embodiment, electronic installation can have touch sensitive surface, and this touch sensitive surface can be reacted to being attached in over cap near a plurality of conducting elements at the internal layer place of over cap.When over cap was attached to electronic installation by magnetic, described a plurality of conducting elements can be grounded.In one embodiment, conducting element can be by predetermined thereby be discernible patterned arrangement.Like this, comprise that can be with the mutual element of touch sensitive surface the time, these elements can be arranged by predetermined pattern, detect the current location of over cap to help electronic installation when the internal layer of over cap.For example, in one embodiment, touch sensitive surface can be capacitive in nature, and in this case, the embedded components in over cap can be formed by conductive material (metal such as aluminium).Conducting element can ground connection, in order to increase the capacitive signals noise ratio by the mutual signal that generates between capacitive touch-sensitive surface and capacitive character embedded components.

Magnetic element in capping section can be mutual with the magnetosensitive circuit that is attached in electronic installation.In one embodiment, the magnetosensitive circuit can adopt the form of HFX sensor, and the existence in external (extrinsic) magnetic field that is provided by the magnetic element in over cap can be provided this HFX sensor.But, should be noted that detected magnetic field must make the HFX sensor saturated in order to trigger the HFX sensor.Like this, greatly reduced the HFX sensor possibility that over cap is sealed the mistake indication of electronic installation is provided.For example, triggers so that the HFX sensor is saturated with relative weak magnetic field intensity deficiency that the magnetic field of the earth is associated the mistake of over cap state is indicated.

When the HFX sensor was exposed to saturation magnetic field (that is, having the magnetic field that is enough to make the saturated magnetic field intensity of HFX sensor), the HFX sensor can (that is, ON/OFF) signal responds this saturation magnetic field by generating scale-of-two.One of advantage that (beyond the possibility that reduces wrong lid state indication) uses the HFX sensor is the required electric power amount less of operation HFX sensor, therefore can not cause excessive power consumption on electronic installation.Under any circumstance, when the HFX sensor was exposed to saturation magnetic field, the HFX sensor can send signal.This signal can be received by processing unit, and is used to change the mode of operation of electronic installation.But, should be noted that as the additional of HFX sensor or substitute, can detect over cap with respect to the state of electronic installation with any suitable sensing apparatus.For example, can use magnetometer (its a kind of form can be used as compass) to replace the HFX sensor.Compare with the HFX sensor, magnetometer is more responsive to external magnetic field, therefore will respond by more continuous (simulation) signal that the expression exterior magnetic field is provided, thereby needs larger electric power amount.Therefore, can be by periodically the signal from magnetometer being sampled, the cause magnetometer detects dynamic magnetic activity (for example, the relative motion of indication magnetometer and magnetic source).For example, can provide magnetic element in over cap with respect to the relative position of the magnetometer in electronic installation with the data of sampling.

Therefore, over cap can comprise the magnetic element such as permanent magnet, and the magnetic field of this magnetic element can make the HFX sensor generate signal.Magnetic element can be placed on the such position on over cap, that is, this position is placed on the surface of electronic installation or triggers the HFX sensor during near electronic installation surperficial at lid and generates signal.This signal can indicate over cap to be in precalculated position with respect to electronic installation, and this precalculated position can cause the change of the mode of operation of electronic installation.For example, in the situation that the part with magnetic element of over cap is near the HFX sensor, can make the HFX sensor generate signal from the magnetic field of magnetic element.Then can mode of operation be changed to the state capped consistent with the part of electronic installation with this signal.For example, when electronic installation comprised display, over cap can be used for covering display, therefore display can not be watched, thereby can forbid display.On the other hand, when the part with magnetic element of over cap is removed when making the position that the HFX sensor no longer responds to the magnetic field of magnetic element, the HFX sensor can generate another signal.This another signal can cause electronic equipment to enter capped from least a portion of display and can watch thereby can show another different mode of operation that vision content is consistent.

Yet the HFX sensor can be enough to make HFX sensor saturated magnetic field to be triggered by any intensity, and the mistake indication to the existence of over cap may be provided thus.Therefore, for fear of this wrong indication, when the HFX sensor is triggered, can inquire additional sensor, the over cap that is provided by the HFX sensor for confirmation is in the indication of closed configuration.In one embodiment, the indicating cover at the HFX sensor place trigger event that is in closed configuration can also make electronic installation inquiry another sensor at least, the closed configuration by the indication of HFX sensor for confirmation.

In one embodiment, electronic installation can be inquired ambient light sensor (ALS).ALS can comprise photosensitive circuit (such as photodiode), and this photosensitive circuit can respond to different incident light (typical form is surround lighting) level.In one embodiment, ALS can ambient light.Yet ALS can be configured to respond surround lighting being detected in many ways.For example, ALS can by just providing signal as long as the photosensitive circuit in ALS detects the amount of ambient light larger than specific environment light quantity (that is, ambient light intensity), respond.In other words, the threshold value amount of ambient light can be the threshold level of regulation.For example, the threshold quantity of " x " lumen can represent to be in the consistent amount of ambient light of closed configuration with over cap, and wherein, value " x " has been considered the light that bleeds from the edge of over cap.Certainly, the threshold value amount of ambient light can be set to any suitable amount that is considered to.For example, be in some situation on (such as daytime) in bright light environments at electronic installation, the light leak amount may be more much higher than the expection light leak amount under darker condition.Therefore, may be much bigger along the light leak amount at over cap edge, be in the consistent threshold value light quantity of closed configuration with over cap and can increase that this fact is taken into account.

In another embodiment, threshold quantity can be consistent with the differential variation of the surround lighting that is detected by the photosensitive circuit in ALS.For example, in the situation that electronic installation is in bright light environments (such as daytime outdoor), when over cap in fact is closed, sizable light leak amount may be arranged also.Yet in order to reduce the uncertainty relevant to how many light leaks are really arranged, ALS can be configured to provide signal based on the differential variation of the light quantity that is detected by the photosensitive circuit in ALS.For example, when over cap was opened, ALS can detect by " y ₁" light quantity that represents of lumen.Yet, when over cap is closed, can be from " y by the light quantity that the photosensitive circuit in ALS detects ₁" lumen becomes " y ₂" lumen.Only at poor (that is, the Δ y=abs (y of the light quantity that detects ₁– y ₂)) in situation greater than predetermined value, ALS just can provide the indication over cap to be in the appropriate signals of closed configuration.The advantage of this method is the following fact: the light leak value is difficult to infer, therefore, by depending on the variation of clearly defined institute ambient light, can obtains the indication of over cap with respect to the more accurate and robust of the state of electronic installation.

Therefore, by using ALS, the indication to the state of over cap that provided by the HFX sensor can be provided electronic installation.Like this, if ALS is in the consistent indication that confirms from the HFX sensor of closed configuration by amount of ambient light and over cap being detected, electronic installation can be accepted the indication from the HFX sensor, and correspondingly changes the mode of operation of electronic installation.Yet; if amount of ambient light is inconsistent with the signal that is in closed configuration from the indication over cap of HFX sensor; electronic installation can inquire another sensor will be for assessment of another data point from the signal of HFX sensor in order to obtain; perhaps more simply; can ignore the indication from the HFX sensor fully; overlay electronic device is fully covered in supposition thus, and therefore, the mode of operation of electronic installation will not be modified as being covered consistent mode of operation fully with electronic installation.Yet, if ALS detects the light quantity that has confirmed from the indication of hall effect sensor, electronic installation can accept from the HFX sensor be in the indication of closed configuration about over cap, and can respond accordingly thus.

In another embodiment, camera can be activated, and the type of the image of catching based on camera, and camera can be used for confirming the indication about the cover closure that the HFX sensor provides.For example, when cover was closed, camera can be caught the image of basic black (perhaps low-down lumen value).Yet, if electronic installation is positioned at dark situation (such as dark room, at night and have seldom or moonless or other external light source outdoor, etc.) in, only exterior lighting (such as from display) can be provided for catching for camera the sufficient light (for example, the terminal user on the face) of image.In one embodiment, the image of catching can characterize with overall lumen value or lumen histogram, and this can be used for determining that lid is fully closed or part is closed.For example, even cover is fully closed, also have some light leaks, this can be caught by camera, thereby causes the image of catching of low lumen.Yet in another embodiment, camera can be regulated by this way, that is, unless enough light is arranged on the image capture apparatus in camera, otherwise camera not can based on for example the regulation the light leak specification and document image.Yet; if camera has been caught image, by assessing the overall lumen value (for example, less than threshold value lumen value) of the image of catching; can estimate the position of over cap, and utilize the position of estimated over cap to confirm (or not confirming) from the indication of HFX sensor.

In another embodiment, can type of service be magnetometer that plate carries compass detect be embedded in over cap in magnetic element be positioned at the existence of HFX sensor place or near the consistent Hard Magnetic skew of correct position.The indication about the closing lid state from the HFX sensor is confirmed in the existence that in this embodiment, can utilize Hard Magnetic to be offset.On the other hand, what electronic installation can utilize Hard Magnetic skew does not exist to judge the misregister about the state of over cap from the HFX sensor, thereby can be left in the basket, and perhaps can take other action, such as another sensor of inquiry.

Shall also be noted that magnetic material that over cap comprises may affect the performance of magnetometer (carrying compass as plate).Especially, the plate basic operation (being implemented as the instruction that can be carried out by processor or other appropriate circuitry) of carrying compass may be modified due to the existence of magnetic material in over cap.Especially, the motion of over cap may be carried compass by plate and be detected variation for magnetic field intensity and direction, and this can cause " mistake ", will experience dynamic deflection based on the change in location of over cap because plate carries compass.For example; when lid from opening configuration when becoming closed configuration; the dynamic deflection that plate carries the compass place may increase because of the following fact: the magnetic element in over cap is mobile near magnetometer; therefore cause that plate carries the larger off-set value of compass reading (certainly; become when opening from closure at the lid state, situation is just opposite).

May be caused by the change in location of magnetic element in over cap, the plate difference of carrying peak excursion that compass experiences or compass azimuth is with plate carries the magnetic field that Magnetic Sensor that compass is associated detects when the change in location of over cap amplitude changes and the function of the horizontal intensity of external magnetic field.For to by over cap (more particularly; magnetic element in over cap) skew that motion causes compensates, and plate carries compass and can utilize the maximum that plate is carried the magnetic field amplitude that compass can detect to change this model of function as the variation of covering the position.Like this; by using maximum with magnetic field amplitude to change as the model of the function of lid position and the current estimation of amplitude of using the horizontal component of external magnetic field, electronic installation can be estimated to be changed by over cap the maximum variation of the compass azimuth that causes with respect to the relative position of electronic installation.

Correspondingly, the accelerometer and the gyroscope that are combined in electronic installation can be combined with compass, assess the dynamic magnetic variation characteristic (signature) of detected external magnetic field.Accelerometer and gyroscope can provide locus and the rotation of electronic installation in real time, and compass can provide the indication that changes about the external magnetic field in real time.The reading of accelerometer and gyroscope and compass can use together, and compares with the model of magnetic element with respect to the motion of electronic installation, is used for thus assessing the possibility (passing through compass) that lid exists and moving with respect to electronic installation.

Below with reference to Fig. 1 to 15 discussion these and other embodiment.Yet, one of ordinary skill in the art will readily recognize that the detailed description that provides with reference to these accompanying drawings only is used for task of explanation here, and should not be interpreted as restrictive.For the remainder of this discussion, suitably be configured to respectively magnetic according to described embodiment and be attached to each other the first object and the second object describing.Yet, should be pointed out that object that the quilt of any quantity and type suitably configures can be attached to each other by mode magnetic accurately and repeatably.Especially, for the purpose of simplification and knowing, for the remainder of this discussion, suppose that the first object adopts the form of electronic installation, adopts the form of hand-hold electronic device particularly.

R is that composite magnetic element ME and plate carry the distance between compass 118.

Therefore, in opening configuration, plate carries compass 118 can detect magnetic flux density according to formula (2):

M _Open=B _ME/ R _Open ²Formula (2)

And in closed configuration, plate carries compass 118 can detect magnetic flux density according to formula (3):

M _Closed=B _ME/ R _Closed ²Formula (3)

Yet, because composite magnetic element ME and plate carry changing with angle of pivot Θ apart from r between compass 118, so the variation of carrying the magnetic flux density M that compass 118 detects by plate can provide the estimation of capping 202 around the motion of pivotal axis 211.Like this, by capping 202 is carried out modeling around the motion of pivotal axis 211, can by assess the variation of the magnetic flux density M of the composite magnetic element ME that is detected by compass 118 according to formula (4), infer the motion of capping 202:

M (Θ)=B _ME/ r (Θ) ²Formula (4)

Wherein: 0≤Θ≤π.

Because board device 100 can not direct-detection angle of pivot Θ, so can utilize accelerometer and the gyroscope (not shown) that board device 100 comprises to obtain indirectly to determine.Accelerometer and gyroscope can provide the dimensional orientation of board device 100, and carrying compass 118, plate can detect total magnetic flux density (comprising the magnetic deflection shown in Fig. 6 A and 6B), whether this total magnetic flux density can compare with dynamic model, rotating around pivotal axis 211 to infer capping 202.

Fig. 6 A and 6B with graphical illustration can be carried the various magnetic deflections that compass 118 detects by plate.For example, the magnetic element in magnetic attachment structure 204 can produce magnetic deflection M1.Magnetic deflection M1 can provide the indication that is attached to board device 100 about over cap 200 magnetic.For example, the variation of magnetic flux density detected according to magnetic deflection M1 if plate carries compass 118, plate carries compass 118 corresponding signal can be provided to the processor in board device 100.Processor can with this signal infer over cap 200 magnetic be attached to board device 100.
