Title: Sliding input device cover

Abstract:
A computing system includes an electronic device, a cover or case for the electronic device, and an input device that is slidably movable yet attached to the cover or case. By positioning the electronic device on top of the input device, rotation of the electronic device which changes its vertical viewing angle also translates the input device. These can provide improved overall possible viewing angle adjustability, increased system stability at high viewing angles, laptop-like opening and closing behavior, lighter weight, and implementation using low-cost components.

Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This is a continuation of U.S. application Ser. No. 16/844,694, filed 9 Apr. 2020, and entitled “SLIDING INPUT DEVICE COVER,” which claims priority to U.S. Provisional Patent Application No. 62/906,572, filed 26 Sep. 2019, and entitled “SLIDING INPUT DEVICE COVER,” the entire disclosures of which are hereby incorporated by reference. 
    
    
     FIELD 
     The present disclosure generally relates to interfaces for electronic devices. In some specific examples, the present embodiments relate to keyboards and covers for touch screen devices. 
     BACKGROUND 
     Many electronic devices have keyboards and related devices to receive input and interaction from users. These electronic devices include computers, such as personal computers, tablet computers, and smartphones, and other “smart” devices, such as media players, video and audio equipment, vehicle consoles, home automation controllers, and related devices. Keyboards and other interface devices are designed with buttons or keys that are pressed by users to generate input signals for a processor or controller. These devices are often designed to provide a controlled amount of resistance to the user&#39;s fingertips in order to give tactile feedback as the user presses a button or key. The feel, sound, cost, and size of each button or key are tightly controlled to efficiently provide a desired user experience. Although some keyboards are “virtual,” such as software keyboards displayed on a touchscreen device, it can be beneficial to provide key travel, or movement of the keys, to help the user more easily feel, see, and hear when and where a key is pressed and to provide an overall more satisfying interaction with the device. 
     Providing this type of key or button can come with costs. Touchscreen devices that do not have a built-in mechanical keyboard can be connected to a peripheral keyboard or a keyboard case or cover, but those devices generally can have keys that are awkwardly sized, can be covered by the touchscreen device, require batteries or internal weights to counterbalance the weight of the touchscreen device, require two hands to operate, and are poorly adjustable. Thus, there are many challenges and areas for improvements in interface devices. 
     SUMMARY 
     One aspect of the present disclosure relates to a computing system comprising an electronic device having a rear surface, a case having a back portion and a bottom portion joined by a hinge, with the back portion being mounted to the rear surface of the electronic device, and an input device in electronic communication with the electronic device and contacting the electronic device and the bottom portion of the case. Rotation of the electronic device relative to the input device can induce lateral translation of the input device relative to the hinge. 
     In some embodiments, the electronic device is rotatable relative to the input device between a first position and a second position, and a center of gravity of the electronic device moves parallel to a direction of translation of the input device upon rotation of the electronic device relative to the input device. The electronic device can also comprise a display, wherein the case and input device are movable relative to each other between an open configuration in which the display is exposed and a closed configuration in which the display is covered by the case or the input device. The electronic device can be selectively attachable to and detachable from the input device. The electronic device can be pivotally mounted to the input device. 
     The position of the input device relative to the hinge can be continuously adjustable within a range of relative positions, the electronic device being stable across an entirety of the range of relative positions. The range of relative positions can include a first position wherein the electronic device is at an about 120-degree angle relative to the input device and a second position wherein the electronic device is at an about 135-degree angle relative to the input device. The input device can be movable between a locked position relative to the bottom portion and an unlocked position relative to the bottom portion as a result of mounting the electronic device to the input device. 
     Another aspect of the disclosure relates to a computer cover comprising a back panel to mount to an electronic device, a bottom panel joined to the back panel by a hinge, with the bottom panel having an inner surface, and an input device mounted to the inner surface of the bottom panel and configured to laterally translate relative to the hinge while mounted to the inner surface. 
     In this cover, the back panel can include a mountable portion to mount to the electronic device and a rotatable portion to connect the mountable portion to the hinge, with the rotatable portion being connected to the mountable portion by a second hinge. The input device can comprise length and width dimensions less than or equal to length and width dimensions of the bottom panel. The input device can comprise a recess in which the electronic device can reside and can be mountable to the bottom panel in at least two different relative positions. The hinge can be a compliant mechanism. The back panel can be movable into a face-to-face orientation with the input device. 
     Yet another aspect of the disclosure relates to an electronic device cover comprising a first panel configured to be mounted to a rear surface of an electronic device, a second panel connected to the first panel at a hinge, and an input device mounted to, positioned over, and translatable relative to the second panel between a first position covering a first proportion of the second panel and a second position covering a second proportion of the second panel, with the second proportion being smaller than the first proportion. 
     In the second position, a portion of the input device can extend laterally away from an edge of the second panel. The input device can be further from the hinge in the second position relative to the first position. The input device can comprise a keyboard and a trackpad surface. The input device can be slidable between the first position and the second position.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims. 
     In the field of tablet computers and related electronic devices, it can be desirable to include a keyboard, track pad, and related input devices in order to give the tablet computer additional user interface functionality similar to a laptop or notebook computer. Conventionally, tablet computers are fitted with cases that include a keyboard or similar feature to protect the tablet in addition to adding such functionality. However, in many cases, using the tablet computer with a keyboard case is awkward and compromising for the user. It can be difficult for the user to find a comfortable viewing angle while the tablet computer is in a typing configuration because the cases only provide a limited number of stable viewing positions. Many do not provide any stability at high viewing angles (e.g., about 120-135 degrees or more relative to a horizontal support surface). For existing cases that provide more adjustability, increasing the viewing angle of the tablet computer tends to make the tablet computer and case assembly increasingly unstable as the tablet computer rotates to greater and greater viewing angles because the center of gravity of the device moves rearward, away from the user, and behind the support surfaces provided by the case. In order to counteract this effect, the cases and keyboards are often required to use heavy or expensive mechanical components such as friction hinges and counterbalance weights. In some cases, functionality and ease of use are sacrificed, such as by removing the track pad or by making the keyboard uncomfortably small, in order to ensure device stability while at high viewing angles. 
     Aspects of the present disclosure relate to a cover or case for an electronic device, such as a tablet computer, wherein the input device is slidably or translatably mounted to a folio (or similar paneled and hinged case or enclosure structure) that mounts to (or that is part of) the electronic device. The electronic device is movable between a stowed or closed position and an opened or viewing position. In the open position, a panel of the case can contact the rear surface of the electronic device, and a bottom edge or bottom surface of electronic device can be supported by and in contact with a top surface of the input device. Rotation of the electronic device while in this configuration can cause sliding or translating movement of the input device relative to the paneled structure. In other words, rotation of the electronic device can apply a horizontal force against the input device that causes it to translate along a panel of the case or cover that is on a support surface. Similarly, application of a horizontal force to the input device can induce rotation of the electronic device due to a connection, attractive force, or contact between the electronic device and the top of the input device. 
     Embodiments of the present disclosure can enable substantially infinite adjustability of the viewing angle of the electronic device (within a range of viewing angle limits or boundaries). In all of those viewing angles, the electronic device can be positioned relative to the input device in a manner that leaves the interactive portions of the input device completely exposed, uncovered, and accessible to the user, even while the device is adjusted. Furthermore, the electronic device and case assembly become more stable as the viewing angle is increased because the center of gravity of the electronic device moves forward as the input device moves forward (i.e., away from the hinge that joins a back panel and bottom panel of the folio). In other words, the center of gravity moves in the same forward direction as the input device translates relative to the bottom portion of the case or cover. Thus, the center of gravity of the electronic device can be described as moving parallel to a direction of translation (and with the same polarity of direction) of the input device upon rotation of the electronic device relative to the input device. For example, if the input device translates in a positive X-direction, the center of gravity of the electronic device also moves parallel to the X-axis in an at least partially positive X-direction (rather than in a negative X-direction) due to having the same polarity as the translation direction of the input device. 
     Therefore, embodiments of the present disclosure can provide laptop-like input device functionality to a tablet computer using relatively inexpensive and lightweight materials. In some embodiments, the keyboard and trackpad can both be provided on the input device without the input device having larger width and length dimensions than the tablet computer itself when the case, computer, and input device are all in a stowed configuration. The input device can be stowed in a safe and compact manner when it is not used. The positioning of the center of gravity of the electronic device over the bottom portion of the case also reduces or eliminates the need for counterbalance weights in the case or friction preload in the hinges of the case. 
     Additionally, moving the tablet computer and input device into a stowed position can be performed using a single-handed closing operation, similar to closing a laptop computer. In other words, when the electronic device is in an open configuration and has its bottom end contacting a retention surface on the top of the input device, a single force applied to the top end of the electronic device (i.e., a force that causes the electronic device to rotate about the bottom surface or about the interface between the electronic device and the input device) can cause the electronic device to rotate in a manner that reduces the viewing angle and, eventually, detaches or dismounts the electronic device from the top surface of the input device (while simultaneously moving the input device rearward into a stowed position) and also moves a front or display surface of the electronic device into the closed position where it faces the input device. Thus, the computing system can be moved into a closed configuration using the same type of arm motion that a user applies to close a laptop computer by turning the display of the laptop down on top of an upward-facing keyboard. 
     In some cases, the sliding input device can be moved between a locked position and an unlocked position relative to the case. In this way, the input device can be prevented from moving (e.g., falling off of or sliding out of the bounds of the length and width dimensions of the closed-configuration case) while it is not being used. Attachment of the electronic device to the input device can cause the input device to unlock relative to the case and to thereby be able to slide and translate. 
     The input device can be made to slide or translate on top of a bottom panel of the folio or case cover while the bottom panel rests on a support surface, or the cover panel can slide beneath the input device while the input device is supporting the assembly on a support surface. The input device can be permanently attached to a back panel of the case, or, in some cases, the input device can be removable from the case panel. For example, the input device can be magnetically held to the case panel and can be non-destructively, reversibly separated from the case panel (while being reattachable thereto without modification of the input device or electronic device or addition of an attaching agent such as an adhesive) to reposition the input device relative to the case panel. 
     Additionally, portions of the case can be attached to each other at hinges. A back panel or back portion can comprise two sub-panels that are joined by a hinge or other connection point. In some cases, the hinge can be designed to have an adjustable connection point between the sub-panels. The back portion of the case can be attached to a bottom portion of the case via a hinge that is a living hinge, and expendable or stretchable hinge, a multi-pivot hinge, or the like. 
     In aspects of this disclosure, the input device can have a wide variety of different types of input reception or output provision, such as, for example, a keyboard, a trackpad, a keyboard plus a trackpad, a supplemental display for the electronic device, or an input device having a dynamic function row or other touchscreen interface. The input device can provide an additional functionality such as storing a trackpad or other small input device inside the input device, providing inductive charging to other accessories, or providing other supplemental features. 
     As used herein, an electronic device is “pivotally mounted” to the input device when the electronic device is pivotable about a pivot axis while in contact with the input device, and the electronic device moves with the input device while the input device translates parallel to a horizontal plane containing the pivot axis. 
     As used herein, the stability of a device or assembly increases (i.e., it becomes more stable) when its center of gravity moves toward its center of width and length dimensions or its center of gravity moves downward. A device or assembly can be considered “stable” in a certain position when, under normal use conditions, a horizontal force applied to a top end of the device tends to make the device slide horizontally on an unobstructed, horizontal support surface rather than rotating (i.e., tipping over). Additionally, modifying the device in some way to increase the amount of force necessary to tip over the device on the horizontal support surface can be referred to as increasing the stability of the device. 
     These and other embodiments are discussed below with reference to the figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting. 
       FIG.  1    illustrates a perspective view of a computing system  100  according to the present disclosure. The computing system  100  can comprise an electronic device  102  having a display  104 . The electronic device  102  can be positioned in a case  106  having a first back portion  108  (i.e., a mountable portion), a second back portion  110  (i.e., a rotatable portion) joined to the first back portion  108  by an upper hinge  112 , and a bottom portion  114  connected to the second back portion  110  by a lower hinge  116 . An input device  118  comprising a keyboard  120  and trackpad  122  or other input surface can be movably mounted to the bottom portion  114 , such as by being slidable or translatable along an axis of translation relative to the bottom portion  114 . For example, the input device  118  can move along the direction shown by the arrow in  FIG.  1   . In other words, the input device  118  can translate along a direction toward or away from the lower hinge  116 . In some embodiments, the input device  118  is simultaneously attached to the bottom portion  114  in a manner preventing vertical movement of the input device  118  relative to the bottom portion  114  (i.e., movement in a direction at least partially normal to the inner surface of the bottom portion  114 ). 
     The electronic device  102  can comprise a tablet computer, a smart phone, a display, similar devices, or combinations thereof that can be used with an input device  118 . Accordingly, the electronic device  102  can include a processor, internal memory, input and output devices, such as a touch screen display, buttons, speakers, haptic feedback generators, related devices, and combinations thereof. Electronic device  102  can beneficially have a substantially planar front surface within which (or on which) the display  104  is positioned. Electronic device  102  can also have a back surface or rear surface that can be generally planar and configured to engage the first back portion  108  of the case  106 . The electronic device  102  can comprise attachment features that help the electronic device  102  stay in engagement with the case  106 , such as internal magnets that attract magnets associated with the case  106 , fasteners, adhesives, related devices, or combinations thereof. In some embodiments, the first back portion  108  is integrally connected to the rear surface of the electronic device  102 , and the case  106  and electronic device  102  are therefore made as a single unit. In this case, the second back portion  110  can still be pivotable relative to the electronic device  102  at an upper hinge  112 . 
     The case  106  can comprise panels in the portions  108 ,  110 ,  114  that are substantially planar and substantially rigid compared to the hinges  112 ,  116 . Accordingly, those panels can provide support to the electronic device  102  and input device  118  when the case  106  is positioned on a support surface below bottom portion  114 . See, e.g., horizontal support surface  200  in  FIG.  2   . The case  106  can comprise a variety of materials, such as leather, a flexible polymer, rubber, an elastomeric material, or other compliant, soft, and bendable materials across its outer surfaces or forming the hinges  112 ,  116 . Accordingly, the hinges  112 ,  116  can be referred to as “living” hinges, wherein the hinges  112 ,  116  are made with a flexible elastic material rather than comprising pivoting, rotating hinges (e.g., a door hinge or pin-in-barrel hinge). In some embodiments, the hinges  112 ,  116  can comprise pivoting hinges instead of, or in addition to, living hinges. 
     The major width and length dimensions of the bottom portion  114  can be substantially equal to the major width and length dimensions of the electronic device  102 . In this manner, the overall size of the computing system  100  can be substantially equal to those major width and length dimensions when the computing system  100  is in a fully stowed configuration. See  FIG.  6   . As used herein, the major width and length dimensions are the largest width and length dimensions of the electronic device  102  and bottom portion  114  and are not the minor thickness dimensions typical to these types of devices. In the electronic device  102 , for example, the major width and length dimensions are measured across the viewing plane through which the display  104  is visible. 
     The input device  118  can include one or more interfaces for receiving input or output from a user. In some embodiments, the input device  118  can be referred to as an interface device or an electronic interface. The keyboard  120  can comprise a set of key switches and key caps used to provide alphanumeric input and other input tasks for the electronic device  102 . The track pad  122  can include a touch-sensitive surface for detecting capacitive or resistive touches such as from a user instrument, e.g., a finger. 
     The input device  118  can have a housing  124  around the keyboard  120  and the trackpad  122 . The housing  124  can have a top surface  126  configured to engage a bottom surface or bottom edge  128  of electronic device  102 . The bottom edge  128  can reside in a groove or depression in the top surface  126 . See  FIGS.  7  and  10   . 
     In some embodiments, the input device  118  can have an electronic connection to the electronic device  102  through a set of conductive pads or other electrical conductors that contact the electronic device  102 . In some cases, the input device  118  can have a wireless connection to the electronic device in addition to, or in place of, a physical or “wired” electronic connection. Such a wireless connection can may be via a wireless communication protocol, e.g., WI-FI®, BLUETOOTH®, similar wireless interfaces, and combinations thereof. Additionally, the input device  118  can have an electrical connection to the electronic device  102  via electrical conductors that pass through the case  106  to the electronic device  102 . For example, the electronic device  102  can have conductive pads on the rear surface of its housing that contact exposed electrical connectors on an inner surface of the first back portion  108  of the case. 
       FIGS.  2 - 6    illustrate side views of the computing system  100  in various configurations and relative component positions.  FIGS.  2 - 5    show the computing system  100  in various open configurations wherein the primary user interface portions of the electronic device  102  and the input device  118  are accessible, viewable, and usable by a user.  FIG.  6    shows a closed configuration wherein the electronic device  102  and the input device  118  are covered by the case  106 , and their primary input or output surfaces are not accessible or viewable. 
     In  FIG.  2   , the viewing angle A 1  defined between the primary surface of the electronic device  102  (i.e., the viewer-facing surface or the display surface) and the top or upward-facing surface of the input device  118  has a relatively high magnitude. In some embodiments, the angle A 1  can have a magnitude of about 135 degrees or more. The distance S indicates the amount of usable area of the input device  118 . Accordingly, even at a high viewing angle, all of the interactive areas of the input device  118  remain accessible and usable by the user. 
     In  FIG.  3   , the viewing angle A 2  is smaller than angle A 1  due to the input device  118  laterally translating relative to the bottom portion  114  and hinge  116 . This lateral translation is also accompanied by rotation of the electronic device  102  about a pivot axis positioned approximately where the electronic device  102  touches the input device  118 . Additionally, an overhang distance D 2  in  FIG.  3   , as measured between the forward-most edge of the input device  118  and the forward-most edge of the bottom portion  114 , is smaller than the overhang distance D 1  in  FIG.  2   . The overhang distances also represent the amount of the input device  118  that overhangs a support surface below the bottom portion  114  or is otherwise not positioned over the bottom portion  114 . The angles between the portions  108 ,  110 ,  114  at the upper and lower hinges  112  and  116  are also greater in magnitude in the orientation of  FIG.  3    as compared to  FIG.  2   . Accordingly, repositioning electronic device  102  in the input device  118  to a smaller viewing angle, such as transitioning from angle A 1  to angle A 2 , can increase the angles at the hinges  112  and  116  while decreasing the overhang distance D 2 . In  FIG.  3   , the amount of usable area of the input device  118  is equal to the distance S shown in  FIG.  2   . Accordingly, changing the viewing angle of the electronic device  102  may not change the amount of the usable input area of the input device  118 . In other words, the usable interactive area of the input device  118  can remain consistent across a spectrum of viewing angles of the electronic device  102 . 
     In  FIG.  4   , the input device  118  translates to a position that is fully retracted, and the input device  118  can be entirely positioned over the bottom portion  114  (or at least with minimal or negligible overhang). The electronic device  102  is at an even more vertical viewing angle, as shown by angle A 3 . In one embodiment, the angle A 3  can be approximately 120 degrees. Additionally, when in the position shown in  FIG.  4   , there is no significant overhang distance (and in some embodiments, no overhang distance at all). The distance S across the accessible and usable portion of the interactive surface of the input device  118 , however, is unchanged. Accordingly, the amount of usable area across distance S remains constant for any viewing angle of the electronic device  102  compared to the input device  118 , at least while the electronic device  102  has its bottom edge  128  on top of the input device  118  in an open configuration. 
       FIG.  5    shows a position wherein the electronic device  102  is closing relative to the input device  118 , as shown by the angle A 4  being smaller in magnitude than the angle A 3 .  FIG.  6    shows a completely closed configuration wherein the front surface of the electronic device  102  is oriented face-to-face with the top surface of the input device  118 , and the portions  108 ,  110 ,  114  of the case  106  protect and sandwich the electronic device  102  and input device  118 . Upon reaching angle A 4 , the electronic device  102  can detach the bottom edge  128  from the input device  118  as the back surface of the electronic device  102  moves into contact with the second back portion  110  and the hinge  112  flattens. Electronic device  102  can be configured to automatically detach bottom edge  128  as a rotating closing force F is applied, for example, to the opposite end of the electronic device  102 . The front outer surface of the electronic device  102  can then close the distance to sit face-to-face with input device  118 . 
     When the computing system  100  is opened from the position shown in  FIG.  6    to the position of  FIG.  5   , the user can pull the electronic device  102  from the input device  118 , thereby pivoting lower hinge  116 , then pivoting the first back portion  108  relative to the second back portion  110  about upper hinge  112  to move the bottom edge  128  of the electronic device  102  into a recess or groove in the input device  118 . In some embodiments, a recess or groove in the input device  118  can be omitted, and the bottom edge  128  can be held against input device  118  using a different mechanism, such as a magnetic latch that attracts the bottom edge  128  to a retention line  130  on the top of the input device  118 . 
     With the bottom edge  128  held at the retention line  130 , the bottom edge  128  (or an axis through the retention line  130 ) can be the pivoting axis for the electronic device  102  relative to the input device  118 . Pivoting the electronic device  102  about that pivoting axis can induce the sliding translation movement of the input device  118  relative to the bottom portion  114 , as illustrated in  FIGS.  2 - 4   . During this rotating movement, the distance S can remain constant, and the entire keyboard  120 , track pad  122 , and any other interfaces of the input device  118  can remain uncovered and usable without moving underneath the electronic device  102 . 
     Furthermore, simultaneous movement of the electronic device  102  and input device  118  can be produced, for example, by manipulating electronic device  102  and case  106  at the top end  132 . In this manner, a user can, with a single-handed operation at the top end  132 , move between open and closed configurations of the computing system  100 . When the computing system  100  is closed by the user, application of the force F can help release the bottom edge  128  from the position of the retention line  130  so that the case  106  can swivel down (about hinges  112  and  116 ) to the position shown in  FIG.  6   . A counteracting force (e.g., a force applied by the user to hold down the input device  118 ) is not required to be applied to the input device  118  or bottom portion  114  to open or close the computing system  100 . 
       FIG.  7    shows a top view of the input device  118 . A recess, trough, or groove  700  is positioned between a rearward edge  702  and the keyboard  120  on the housing  124  and in the top surface  126 . The length of recess or groove  700  can be equivalent to the length of the electronic device  102  that contacts the input device  118 . The groove  700  can extend along the retention line  130  and can be the connection location for the electronic device  102  against the input device  118  at the top surface  126 . The length S can extend from the groove  700  to a front edge of the input device  118 , as shown in  FIG.  7   . The length S can include sufficient space for a standard-sized keyboard  120  and a trackpad  122 . 
       FIGS.  8  and  9    show side section views of an embodiment of the electronic device  802  (which can be, for example, electronic device  102 ) positioned in the groove  700 . The input device  818  and bottom portion  814  are shown below the electronic device  802 . The groove  700  can comprise a rear surface  803  and a bottom surface  804  configured to respectively engage a rear surface  806  and a bottom surface  808  of the electronic device  802 . 
     Magnetic elements  810 ,  812  in the electronic device  802  and in the input device  818 , respectively, can be attracted to each other in a manner that helps to keep the electronic device  802  within the groove  700  while the electronic device  802  is in an open position relative to the input device  818 . The magnetic elements  810 ,  812  can apply a sufficient attractive force to each other to keep the electronic device  802  seated in the groove  700  at relatively high viewing angles, such as when the electronic device  802  is positioned at the angle shown in broken lines in  FIG.  8    and the magnetic elements  810 ,  812  are spaced further apart than in the position shown in solid lines. Accordingly, the magnetic elements  810 ,  812  can keep the electronic device  802  at least partially held in the groove  700  (i.e., the electronic device  802  is at least partially within the recess of the groove  700  and below the adjacent top surface of the input device  818 ) even when the electronic device  802  is not in full contact with the surfaces  803 ,  804  of the groove  700 . The magnetic elements  810 ,  812  can each comprise a permanent magnet, an electromagnet, a ferrous or other magnetically-attracted material, or combinations thereof, provided that at least one of the magnetic elements  810 ,  812  includes a magnetic field generating element configured to attract the other magnetic element. 
     The magnetic attraction between the electronic device  802  and the input device  818  can ensure that a force (e.g., force F) applied to the top end (e.g.,  132 ) of the electronic device  802  can transfer the force and slide the input device  818  relative to the bottom portion  814  of the case as the electronic device  802  rotates at the retention line (e.g.,  130 ) or groove  700 . At sufficiently high (or low) viewing angles, the electronic device  802  can rotate out of the groove  700  enough to sufficiently weaken the attraction between the magnetic elements  810 ,  812  and thereby allow the electronic device  802  to detach from the input device  818 . Alternatively, a user pulling vertically upward on the electronic device  802  or downward on the input device  818  can overcome the magnetic attraction to the input device  818  in a manner that allows disconnection of the electronic device  802  from the input device  818 . 
     Furthermore, as shown in  FIG.  9   , a sufficient reduction in the viewing angle (as indicated in broken lines) can weaken the force of attraction between the magnetic elements  810 ,  812  in a manner that allows the electronic device  802  to be removed from the groove  700 . In some cases, a forward stop  820  (e.g., the side of a ridge) can be positioned on the top surface of the input device  818  or on a front side of the groove  700  in order to help facilitate removal of the electronic device  802  from the groove  700 , as shown in broken lines in  FIG.  9   . When a front bottom edge  822  of the electronic device  802  contacts the forward stop  820 , the forward stop  820  can ensure that the electronic device  802  begins to rotate out of the groove  700  rather than sliding or translating the front bottom edge  822  forward across the top of the input device  818 . The rotation of the device  802  can assist the user in overcoming the magnetic attraction between the magnetic elements  810 ,  812 . 
     In some embodiments, a mechanism can be provided to remove the electronic device  802  from the groove  700 . For example, forward rotation of the electronic device  802  relative to the input device  818  can cause a protrusion within the input device  818  or electronic device  802  to protrude in the groove  700  and to thereby drive the electronic device  802  out of the groove  700 . In this manner, the mechanism can automatically assist the user in moving the electronic device  802  from a position similar to  FIG.  4    to a position similar to  FIG.  5    or from a position similar to the solid-line position of the electronic device  802  in  FIG.  9    to the broken-line position shown in  FIG.  9   . In other words, movement of the protrusion can apply a force to the electronic device  802  to overcome the attractive force of the magnetic elements in the electronic device  802  and the input device  818 . 
     In some embodiments, the input device  818  can have a rotatable structure at the position of the retention line  130 , and the rotatable structure can be configured to engage and retain the electronic device  802  while being capable of simultaneously rotating with the input device  818 . For example, the rotatable structure can cup the bottom of the electronic device  802  in a groove similar to groove  700  and can pivot with the bottom of the electronic device  802  relative to the input device  818 . In this way, the rotatable structure can provide a consistent amount of support for (e.g., can provide consistent magnetic attraction force to) the electronic device  802  within a wide range of viewing angles. 
     In some cases, the input device and the bottom portion can be releasably, positionally lockable to each other. When in a locked configuration, the input device can be prevented from translating relative to the bottom portion, and in an unlocked configuration, the input device can be slidable relative to the bottom portion as usual.  FIG.  10    shows a side view of another embodiment wherein the input device  1018  comprises a receptacle  1040 , and the bottom portion  1014  comprises a movable protrusion  1042 . The protrusion  1042  can extend into the receptacle  1040  and can thereby mechanically prevent movement of the input device  1018  along a horizontal direction (e.g., as shown by the double-sided arrow in  FIG.  10   ) by physical interference between the protrusion  1042  and the receptacle  1040 . This locked configuration can prevent the input device  1018  from sliding out of the case while the computing system (e.g.,  100 ) is in a stowed or closed position (e.g., as shown in  FIG.  6   ) or while the electronic device  1002  is detached from the input device  1018  (e.g., as shown in  FIGS.  5  and  10   ). 
     When the input device  1018  is seated in the groove  1000 , the protrusion  1042  can be moved downward and out of the receptacle  1040 . In some embodiments, magnetic elements  1016 ,  1020  in the electronic device  1002  and the protrusion  1042 , respectively, can repel each other and thereby apply a downward-directed force to the protrusion  1042  that causes it to translate out of the receptacle  1040 . Once this occurs, the input device  1018  can be in an unlocked configuration, and it can slide laterally across the top surface of the bottom portion  1014  of the case. The protrusion  1042  can be biased upward by a biasing member  1044  (e.g., an elastic dome or spring). Therefore, placing the electronic device  1002  against the groove  1000  can overcome the biasing force of the biasing member  1044  to move the protrusion  1042 . Movement of the input device  1018  from a deployed position relative to the bottom portion  1014  (e.g., the position of  FIG.  3   ) to a retracted position (e.g., the position of  FIG.  4   ) can realign the protrusion  1042  and the receptacle  1040 , and removal of the electronic device  1002  from the groove  1000  can allow the protrusion  1042  to return into the receptacle  1040 , thereby locking the input device  1018 . 
     Although magnetic elements  1016 ,  1020  are shown in  FIG.  10   , the protrusion  1042  can be moved using other mechanics or physical forces. For example, inserting the electronic device  1002  into the groove  1000  can cause a linkage or sliding member to move the protrusion  1042  out of the receptacle  1040 . Additionally, although the protrusion  1042  and receptacle  1040  are shown respectively on the input device  1018  and the bottom portion  1014  near the groove  1000 , their positions can be reversed or relocated on either device. If their positions are reversed, the protrusion  1042  can be attracted to the electronic device  1002  (or otherwise moved upward) in order to unlock the input device  1018  from the bottom portion  1014 . 
     In some embodiments, the input device  1018  can be spring-loaded, wherein positioning the electronic device  1002  on the retention line (or in the groove  1000 ) unlocks the input device  1018  relative to the bottom portion  1014  and a biasing device causes the input device  1018  to automatically slide from a retracted, locked position (e.g., as shown in  FIG.  4   ) to an extended, unlocked position (e.g., as shown in  FIG.  3   ). Accordingly, the input device  1018  can automatically be unlocked and simultaneously translate away from the hinge of the case when the electronic device  1002  is mounted to the input device  1018 . This can help the user bring the electronic device  1002  and input device  1018  into a normal viewing or using position more quickly when opening the computing system and can encourage use of the assembly in the unlocked, deployed configuration. 
       FIG.  11    shows a perspective view of other elements of the computing system  1100 . In this view, the electronic device  1102  is mounted to the input device  1118  and case  1106 . The electronic device  1102  is mounted by magnetic elements  1116  associated with the first back portion  1108  and in the electronic device  1102 . The first back portion  1108  is therefore held against the electronic device  1102  by a magnetic attraction force between the parts. 
     A pin-and-slot configuration can guide the movement of the input device  1118  relative to the bottom portion  1114  of the case  1106 . The pins  1120  can be part of the input device  1118 , and the slots  1122  can be part of the bottom portion  1114 , or vice versa. The pins  1120  can be substantially stationary relative to the input device  1118 , and the slots  1122  can be stationary relative to the bottom portion  1114 . Thus, movement of the input device  1118  relative to the bottom portion  1114  can cause the pins  1120  to traverse the slots  1122  within the limits of the ends of the slots  1122 . Furthermore, the pins  1120  and slots  1122  can guide the movement of the input device  1118  so that it is constrained to movement along an axis of motion relative to the bottom portion  1114  (i.e., instead of a within a plane of motion or within a three dimensional range of positions relative to the bottom portion  1114 ). The input device  1118  can be infinitely adjustable relative to the bottom portion  1114  within the range defined by pin movement within the slots. In other words, the input device  1118  can be moved within a range of positions, and the movement within that range can include an infinite number of minute, discrete adjusted positions in which the electronic device  1102  is stably supported. The input device  1118  is therefore not limited to being used in a limited number of different stable positions for the electronic device  1102 . 
       FIG.  11 A  shows a diagrammatic top view of a pin  1120  in a slot  1122 . The pin  1120  can be movable along the slot  1122  to extreme end positions  1124 ,  1126  wherein the pin  1120  contacts the ends of the slot  1122  and therefore limits movement of the input device  1118  relative to the bottom portion  1114  of the case  1106 . In some embodiments, the slot  1122  can comprise one or more detents  1128 ,  1130 , and the pin  1120  can be biased by a biasing member  1132  in a direction toward the side of the slot  1122  having the detents  1128 ,  1130 . In this manner, the pin  1120  can be biased into positions seated in a detent  1128 / 1130 , and the user must provide an increased input force to the electronic device  1102  (e.g., force F) or to the input device  1118  in order to slide the input device  1118  as compared to positions in which the pin  1120  is not in a detent  1130 . In other words, the user can be required to overcome the biasing force to move the pin  1120  from the detent  1128 / 1130 . With this feature, the input device  1118  can be soft-lockable into preferred viewing positions for the electronic device  1102  that correspond to typical viewing angles. For example, the detents  1128 ,  1130  can correspond with typically preferred viewing positions of  FIGS.  2  and  3   . Use of the detents  1128 ,  1130  can limit unwanted or inadvertent viewing angle adjustment of the electronic device  1102  while the pin  1120  is seated therein. 
     Although a pin and slot interface is shown in  FIG.  11   , other types of motion-limiting structures can be used to control lateral translation of the input device  1118  relative to the bottom portion  1114 , such as gears, limited-length springs, ridge-in-groove features, similar structures, and combinations thereof. Therefore, many types of lateral motion constraints can be used to guide movement of the input device  1118  relative to the bottom portion  1114 . Furthermore, features of the input device  1118  and bottom portion  1114  can prevent separation of the input device  1118  from the bottom portion  1114  in a vertical direction (e.g., in a direction parallel to a normal direction extending from the top surface of the input device  1118 ). 
       FIG.  12    shows another configuration wherein the input device  1218  is removable from the bottom portion  1214  of the case  1206 . In this example, the input device  1218  can be releasably mountable to the bottom portion  1214  by connectors such as magnetic elements in the case  1206 , device  1218  or mechanically interlockable parts. The bottom end  1228  of the electronic device  1202  can be configured to contact the inner surface  1230  of the bottom portion  1214  when the input device  1218  is removed. 
     Removal of the input device  1218  can allow the user to reposition the input device  1218  to any preferred position relative to the electronic device  1202 . Additionally, features on the bottom portion  1214  such as an external track pad  1240 , display, or other interface device can be exposed and usable upon removal of the input device  1218  from the bottom portion  1214 . In some embodiments, the input device  1218  can have an interface element  1242  such as a keyboard that is accessible and usable upon attachment of the input device  1218  with its top surface  1226  facing upward, and the interface element  1242  can be moved into a covered, stowed, and protected position by turning over the input device  1218  so that the top surface  1226  faces the surface  1230  of the bottom portion  1214 . In that position, the case  1206  and input device  1218  can be mounted to each other so that the interface element  1242  is hidden or blocked from user interaction. In this manner, the interface element  1242  can be protected from receiving inadvertent or unwanted input or providing unneeded output. For example, the bottom portion  1214  can be rotated about the hinge to be positioned against the back portions  1208 ,  1210 , and the input device  1218  can be stowed in a position that prevents the user from accidentally providing input via the interface element  1242  while it is behind the electronic device  1202 . See also  FIGS.  16 A- 16 B . The input device  1218  can therefore be moved into a face-to-face orientation with the back portions  1208 ,  1210 . 
       FIG.  13    shows a perspective view of an additional embodiment of the computing system  1300 . The input device  1318  is shown with a generic interface area  1320  to illustrate that the input device  1318  can comprise a variety of user interface elements such as a keyboard, display, track pad (e.g., a track pad covering substantially all of the interface area  1320 ), etc. In some embodiments, the input device  1318  can further comprise an auxiliary input device  1322  that is translatable between a stowed position within a recess  1324  of the input device  1318  (or within a recess of the bottom portion  1314 ) and an active or usable position extending from the recess  1324  (as shown in  FIG.  13   ). The auxiliary input device  1322  can comprise a track pad or other interface device described herein. The auxiliary input device  1322  can extend from a front or lateral side surface of the input device  1318 . 
       FIG.  14    shows a side view of another embodiment wherein the electronic device  1402  is mounted to a case  1406  and to an input device  1418  that allows a different type of translation between the parts. Here, the input device  1418  remains stationary relative to a support surface  1450  while the bottom portion  1414  of the case  1406  is slidable between various positions. Accordingly, relative movement of the bottom portion  1414  and the input device  1418  can comprise movement of the input device  1418  or the case  1406  relative to support surface  1450 . Movement of the case  1406  instead of the input device  1418  relative to the support surface  1450  can beneficially keep the input device  1418  still as the electronic device  1402  is rotated, similar to how a keyboard portion of a laptop computer is stationary as the display portion is rotated. Accordingly, the embodiment of  FIG.  14    can provide a user experience that is more similar to a laptop computer user experience by minimizing sliding of the keyboard. 
       FIG.  15    is a side view of another embodiment of a computing system  1500  wherein the first hinge  1512  comprises a slidable, rollable, or otherwise movable connection between the first back portion  1508  and the second back portion  1510  of the case  1506 . Accordingly, the viewing angle R of electronic device  1502  relative to the input device  1518  can increase by movement of the first hinge  1512  relative to the back portion  1508  even if the input device  1518  does not slide. In some embodiments, that hinge  1512  can include a wheel  1520  or other pin or roller that is movable longitudinally along the back portion  1508 , such as within a track  1522  therein. The broken lines in  FIG.  15    indicate an alternate tilted position of electronic device  1502  and back portion  1508 . A properly designed amount of friction or preload in the wheel  1520  and track  1522  interface can limit the amount of unintentional or unwanted movement of the wheel  1520  relative to the track  1522 . 
     In another example embodiment, the back portions  1508 ,  1510  can be slidable relative to each other. Thus, rather than a hinge  1512  having a wheel  1520  and track  1522 , one of the back portions  1508 ,  1510  can be bendable and can have an end that bends to slide across or underneath the other back portion  1510 ,  1508 . For example, an upper end of the back portion  1510  can slide between the other back portion  1508  and the electronic device  1502  as the viewing angle of the electronic device  1502  increases, and that upper end can slide out as the viewing angle decreases. A predetermined amount of friction between the sliding panel and the stationary panel or electronic device  1502  can limit the amount of unintended or unwanted movement of the panels relative to each other. 
       FIGS.  16 A and  16 B  illustrate side views of a case  1606  having an expandable and collapsible hinge  1612 . The hinge  1612  can connect a back portion  1608  that is mounted to an electronic device  1602  to a bottom portion  1614 . In some embodiments, the input device  1618  is removable from the bottom portion  1614 , as discussed in connection with at least  FIG.  12   . Accordingly, the hinge  1612  can accommodate the difference in thickness T between the portions  1608 ,  1614  of the case  1606 . As shown in  FIG.  16 A , the hinge  1612  can comprise three pivots  1615 ,  1617 , and  1619  joining two rotatable panel members  1620  and  1622 . When an input device is not included, the thickness T 1  is reduced as compared to thickness T 2 , so the center pivot  1615  moves laterally outward and away from that electronic device  1602  in order for the bottom portion  1614  to contact the electronic device  1602 . When the input device is included, the pivot  1615  expands and straightens to align the rotatable panel members  1620  and  1622 , thereby accommodating the increased thickness T 2  within the case  1606 . 
     Although a pivoting hinge embodiment is shown in  FIGS.  16 A and  16 B , other types of hinges can be used to obtain the change in the thickness T of the gap between the back portion  1608  and bottom portion  1614  of the case  1606 . For example, the hinge  1612  can instead comprise an elastic material configured to stretch and expand to accommodate the thickness T 2  and to relax and shrink to match thickness T 1 . In that embodiment, the hinge  1612  may not necessarily move laterally outward away from the electronic device  1602  when in a reduced-thickness configuration (e.g., as shown in  FIG.  16 A ). In another embodiment, the hinge  1612  can elastically bend to bulge outward and away from the electronic device  1602  when the thickness T is reduced. 
     To the extent applicable to the present technology, gathering and use of data available from various sources can be used to improve the delivery to users of invitational content or any other content that may be of interest to them. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, TWITTER® ID&#39;s, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to deliver targeted content that is of greater interest to the user. Accordingly, use of such personal information data enables users to calculated control of the delivered content. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of advertisement delivery services, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In another example, users can select not to provide mood-associated data for targeted content delivery services. In yet another example, users can select to limit the length of time mood-associated data is maintained or entirely prohibit the development of a baseline mood profile. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the content delivery services, or publicly available information. 
     The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the described embodiments. However, it will be apparent to one skilled in the art that the specific details are not required in order to practice the described embodiments. Thus, the foregoing descriptions of the specific embodiments described herein are presented for purposes of illustration and description. They are not target to be exhaustive or to limit the embodiments to the precise forms disclosed. It will be apparent to one of ordinary skill in the art that many modifications and variations are possible in view of the above teachings.
