Embodiment

Describe illustrative exemplary embodiment in the accompanying drawing below 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 replacement in the spirit that can be included in described embodiment and the scope, revise and be equal to, like that claim limits enclosed.

Below describe the mechanism that can be used to confirm accessories apparatus with respect to the state of the host apparatus that is associated that relates generally to, 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 the capping of this articulated section pivotally.Capping can be around the articulated section along the rotation of direction so that be sealed on and contact electronic installation in the closed configuration basically.Conversely, capping can pivot along another direction around hinge assembly and expose electronic installation to open in the configuration.In one embodiment, when over cap is detected as when being in closed configuration, electronic installation can be done in the closing lid mode; And open when configuration when over cap is detected as to be in, electronic installation can be operated opening under the cover mold formula.Over cap can provide the protection to some aspect (such as display) of electronic installation, promotes the overall appearance and the sensation of electronic installation simultaneously.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 pivot and be connected to capping, and this capping can place on the part that will protect of electronic installation.Over cap can comprise can with the electronic circuit of electronic component in electronic installation cooperation 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 to revise the operation of electronic installation, the electronic circuit of over cap or the operation of other element, or the like.

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 orientation (directional bearing) that is set to indicate the external magnetic field and size.Like this, can infer the orientation (directional heading) of electronic installation with respect to the external magnetic field.For example, when the external magnetic field came down to the magnetic field of the earth, 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 the magnetic element that is used for the attached magnetic element of magnetic and is used to trigger Hall effect (HFX) sensor of electronic installation.In the case, can use plate to carry compass carries the influence detection capping of compass to plate based on magnetic element existence.

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

In one embodiment, electronic installation can have touch sensitive surface, and this touch sensitive surface can be reacted to being attached in the 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, said 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 embedding element in the over cap can be formed by conductive material (metal such as aluminium).Conducting element can ground connection, so that increase the capacitive signals noise ratio by the mutual signal that generates between capacitive touch-sensitive surface and the capacitive character embedding element.

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

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 comes this saturation magnetic field is responded through generating scale-of-two.One of advantage that (beyond the possibility that reduces wrong lid state indication) used the HFX sensor is that the required amount of power of operation HFX sensor is less relatively, therefore can on electronic installation, not cause excessive power consumption.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 use any suitable sensing apparatus to detect the state of over cap with respect to electronic installation.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 responsive more to external magnetic field, therefore will respond through more continuous (simulation) signal that the expression exterior magnetic field is provided, thereby needs bigger amount of power.Therefore, can be through 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 use the data of being sampled to provide magnetic element in the over cap with respect to the relative position of the magnetometer in the electronic installation.

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 the over cap, that is, this position places 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 the 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, under the situation of the part with magnetic element near the HFX sensor of over cap, can make the HFX sensor generate signal from the magnetic field of magnetic element.Then can use this signal that the part that mode of operation changes to electronic installation is capped corresponding to state.For example, when electronic installation comprised display, over cap can be used to cover 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 moved away to when making the position that the HFX sensor no longer responds to the magnetic field of magnetic element, the HFX sensor then can generate another signal.This another signal can cause at least a portion of electronic equipment entering and display not to be capped and can to watch thereby can show corresponding to another different operating states of vision content.

Yet the HFX sensor can be enough to make the saturated magnetic field of HFX sensor to be triggered by any intensity, and the mistake indication to the existence of over cap possibly is 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 trigger event that the indication at HFX sensor place lid is in closed configuration can also make electronic installation inquire 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 a surround lighting) level.In one embodiment, ALS can ambient light.Yet ALS can be configured to respond detecting surround lighting with many modes.For example, ALS can respond through as long as the photosensitive circuit in the ALS detects the amount of ambient light bigger than specific environment light quantity (that is, ambient light intensity) signal just being provided.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 be represented to be in the corresponding to 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 under some situation on (such as daytime) in the bright light environments at electronic installation, the light leak amount maybe be more much higher than the expection light leak amount under darker condition.Therefore, maybe be much bigger along the light leak amount at over cap edge, be in the corresponding to threshold value light quantity of closed configuration with over cap and can increase so that this fact is taken into account.

In another embodiment, threshold quantity can be with consistent by the differential variation of the detected surround lighting of photosensitive circuit among the ALS.For example, be at electronic installation under the situation of bright light environments (such as daytime outdoor), when over cap in fact is closed, also have sizable light leak amount.Yet in order to reduce the uncertainty relevant with how many light leaks are really arranged, ALS can be configured to based on the differential variation by the detected light quantity of photosensitive circuit in the ALS signal is provided.For example, when over cap was opened, ALS can detect by " y 1" light quantity represented of lumen.Yet, when over cap is closed, can be by the detected light quantity of the photosensitive circuit among the ALS from " y 1" lumen becomes " y 2" lumen.Only at poor (that is Δ y=abs (y, of detected light quantity 1-y 2)) under the 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, through depending on the clearly variation of institute's ambient light of definition, can obtain the indication of over cap with respect to the more accurate and robust of the state of electronic installation.

Therefore, through using ALS, electronic installation can confirm the indication to the state of over cap that provided by the HFX sensor.Like this, if ALS is in the consistent indication that confirms from the HFX sensor of closed configuration through detecting amount of ambient light with over cap, then 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, then electronic installation can be inquired another sensor so that obtain to be used to assess another data point from the signal of HFX sensor, perhaps more simply; Can ignore indication fully from the HFX sensor; Overlay electronic device is fully covered in supposition thus, and therefore, the mode of operation of electronic installation will not be modified to being covered corresponding to 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 that the HFX sensor provides is closed about lid.For example, when lid 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 the outdoor of seldom perhaps moonless or other external light source arranged; Or the like) in; Only exterior lighting (such as from display) can be provided for catching the sufficient light (for example, the terminal user on the face) of image for camera.In one embodiment, the image of being caught can use overall lumen value or lumen histogram to characterize, and this can be used for confirming that lid is complete closure or part closure.For example, even lid is closed by fully, 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, only if enough light is arranged on the image capture apparatus in camera, otherwise camera can be based on for example light leak specification and the document image of regulation.Yet; If camera has been caught image, then through assessing the overall lumen value (for example, less than threshold value lumen value) of the image of being caught; 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 that magnetometer that plate carries compass detects and be embedded in the existence that magnetic element in the over cap is positioned at HFX sensor place or near the corresponding to Hard Magnetic skew of correct position.In this embodiment, can utilize the existence of Hard Magnetic skew to confirm indication about the closing lid state from the HFX sensor.On the other hand, electronic installation can utilize not existing of Hard Magnetic skew 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 the magnetic material that comprises in the over cap possibly influence the performance of magnetometer (carrying compass like 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 possibly be modified owing to the existence of magnetic material in over cap.Especially, the motion of over cap possibly carried compass by plate and detected the 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 possibly increase because of the following fact: the magnetic element in the over cap is moving near magnetometer; Therefore cause that plate carries the bigger off-set value of compass reading (certainly, become when opening from closure at the lid state, situation is just opposite).

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

Correspondingly, the accelerometer and the gyroscope that are combined in the electronic installation can be used in combination with compass, assess the dynamic magnetic variation characteristic (signature) of detected external magnetic field.Accelerometer and gyroscope can provide the 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 assessing the possibility (through compass) that lid exists and moving with respect to electronic installation thus.

To open configuration in order being converted to, can to apply release force F capping 202 from closed configuration ReleaseRelease force F ReleaseCan overcome attachment structure 207 and the magnetic attraction between the attachment structure 110 in the board device 100 in the capping 202.Therefore, over cap 200 can be fixed to board device 100, up to capping 202 is applied release force F ReleaseTill.Like this, capping 202 can be used for over cap glass 106.For example, over cap 200 can be attached to board device 100 by magnetic.Capping 202 can place subsequently that magnetic is fixed to cover glass 106 on the cover glass 106 and through the magnetic interaction between magnetic attachment structure 20 and 207.Can be through directly applying release force F to capping 202 ReleaseAnd capping 202 is unclamped from cover glass 106.Release force F ReleaseCan overcome the magnetic attachment between magnetic attachment structure 20 and 207.Therefore, capping 202 can unhinderedly be removed from cover glass 106 subsequently.

Fig. 4 shows the vertical view of a specific embodiment of over cap 200 that form is the lid 300 of segmentation.The lid 300 of segmentation can comprise body 302.Body 302 can have the size and dimension that meets board device 100.Body 302 can be by single-piece collapsible or flexible material form.Body 302 also can be divided into a plurality of sections that are separated from each other through the fold domain.Like this, these sections can be relative to each other folding at the place, fold domain.In one embodiment, body 302 a plurality of material layers that can form rhythmo structure by being attached to one another form.Each layer can adopt the form of from one piece, and this from one piece can have the size and dimension that meets body 302.Each layer only also can have a part of corresponding size and dimension with body 302.For example, can be attached to this section with rigidity or semi-rigid material layer that section has a roughly the same size and dimension or otherwise be associated with this section.

In another example, rigidity or the semi-rigid material layer that has a size and dimension that meets body 302 can be used for providing as a whole with elastic substrates the lid 300 of segmentation.Should be pointed out that these layers all can be formed by the material of the attribute with expectation.For example, the contacted layer of the lid 300 and friable surface such as glass of segmentation can be formed by the soft material that can not damage or destroy this friable surface.In another embodiment, can use the material such as microfibril, it can clean friable surface passively.On the other hand, be exposed to external environment condition the layer can form by more coarse and durable material (like plastics or leather).In another embodiment, capacitive element 208 can be incorporated in the rhythmo structure of cap assemblies 300.

In a specific embodiment, the body 302 of segmentation can be divided into a plurality of sections 304-310, is distributed with narrower foldable portion 312 between these sections 304-310.Among these sections 304-310 each can comprise the one or more emboluss that are placed in one.For example, these sections can comprise the bag zone that wherein can place embolus, perhaps replacedly, embolus can the section of being embedded in (for example, insert moulding (insert molding)).If used bag, then the bag zone can have the size and dimension that holds corresponding embolus.These emboluss can have different shape, but the most typically are shaped as the overall appearance (for example, rectangle) of the body 302 that meets segmentation.Embolus can be used to provide the support structure to the body 302 of segmentation.That is, embolus can provide hardness to cap assemblies.In some cases, embolus can be called as stiffened member (stiffener).Therefore, except outside the narrower foldable area place that does not comprise embolus (for example, allow folding), cap assemblies is relatively harder, makes the more healthy and stronger and operation more easily of lid 300 of segmentation.In one embodiment, section 304,306 and 310 dimension scales with respect to section 308 can be about 0.72 to 1, about 72% of the width of section of this means 304,306 and 310 the width dimensions section of being 308.Like this, can form triangle (that is, be described below, be approximately 75 °, be approximately 11 ° for keyboard base and be used for keyboard region) for the display seat with suitable angle.

Section 306,308 and 310 can comprise embolus 314,316 and 318 (illustrating with the dash line form) respectively.Embolus 314-318 can be by being that body 302 increases flexible rigidity or semi-rigid material forms.The example of operable material comprises plastics, spun glass, carbon fiber composite, metal etc.Section 304 can comprise embolus 320; This embolus 320 also can be formed by resilient material (like plastics); And be set to hold magnetic element 322, some in these magnetic elements 322 can interact with the magnetic element (more specifically being attachment structure 110) in the board device 100.Embolus 314-318 also can hold capacitive element 208, and this capacitive element 208 can be by the responsive part of the MT institute sensing of the display of board device 100.

Because the body 302 of segmentation can fold, more particularly, owing to each section can relative to each other fold, so magnetic interaction take place the active embolus 324 of magnetic that the major part in the magnetic element 322 can be used for and be embedded in the embolus 318.Through active embolus 324 and magnetic element 322 magnetic are bound, can form various supporting structures, some in these supporting structures can be triangular shaped.The triangle supporting structure can help the use of board device 100.For example, can use a triangle supporting structure to come bearing flat plate device 100 in such a way, that is, making can be by with respect to the horizontal plane becoming about 75 ° hope visual angle to present vision content.Yet in order suitably to fold the lid 300 of segmentation, section 308 can be designed to the section of being a bit larger tham 304,306 and 310 (these have same size usually) dimensionally.Like this, these sections can form has two equilateral and triangles than the 3rd long limit, and this triangle has an about interior angle of 75 °.
