     FIELD 
     The described embodiments relate generally to computing device cases and covers. More particularly, the present embodiments relate to cases that can serve as a stand for the computing device and that provide some amount of torsional force for canceling out static and dynamic loads of the computing device when upright, or at least partially upright. 
     BACKGROUND 
     Computing devices have become increasingly portable as a result of advances in component manufacturing that have yielded more compact electronic components. Many of these computing devices include flat screens that allow for viewing digital content in almost any environment. In situations where a user may prefer a computing device to be in a static position for an extended period of time, there may be limited resources for adequately standing the computing device upright for viewing the flat screen. Moreover, certain stands may be limited to a single upright position, thereby limiting the ways a user can interact with the computing device while the computing device is being supported by the stand. 
     SUMMARY 
     This paper describes various embodiments that relate to folio cases for computing devices. In some embodiments, a case for a computing device is described. The case includes cover portions configurable as a stand for the computing device, and a flexible region between the cover portions. The flexible region is configured to provide a torsional force that counteracts at least some force exerted by the computing device when the cover portions are configured as the stand. 
     In other embodiments, a case configurable as a stand for a computing device is set forth. The case can include at least a first cover comprising a first flexible region and at least one cover layer disposed over the first flexible region, and a second cover connected to the first cover by at least a second flexible region. The first flexible region and the second flexible region are configured to provide torsional forces that counteract a weight of the computing device when the first cover and the second cover are arranged as the stand for the computing device. 
     In yet other embodiments, a system is set forth. The system includes at least a device cover configurable as both a stand and a protective cover for a computing device. The system also includes a flexible component disposed within the device cover such that the flexible component provides a torsional spring force that counteracts static and dynamic forces exerted by the computing device when the device cover is configured as the stand. 
     Other aspects and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the described embodiments.

     DETAILED DESCRIPTION 
     In the following detailed description, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments in accordance with the described embodiments. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the described embodiments, it is understood that these examples are not limiting; such that other embodiments may be used, and changes may be made without departing from the spirit and scope of the described embodiments. 
     Computing device cases provide a number of benefits for users who seek to protect their respective computing devices from weather, collisions, and general wear over the lifetime of the computing device. The cases discussed herein are purposed as multi-function cases that can not only protect a computing device from damage, but also provide support for the computing device when the case is operating as a stand. The cases described herein can support the computing device in multiple positions while accounting for the static load (that is, the weight) of the computing device. Further, the cases may support a dynamic load received by the computing device during use. A “dynamic load” may be referred to as a force, or forces, applied exerted on the computing device during use, such as when a user is touching the computing device. For example, in some embodiments, the case includes two cover portions configurable as a stand for the computing device. A flexible region can be connected between the two cover portions. The flexible region can provide a torsional force that counteracts at least some amount of static weight of the computing device when the two cover portions are configured as the stand. 
     When the case is arranged as a stand for the computing device, at least a portion or a majority of a static load of the computing device can be canceled by the case. Additionally, the dynamic loads experienced by the computing device can be at least partially canceled by mechanical features of the case. Such mechanical features can include one or more springs, and/or one or more flexible layers disposed within one or more flexible regions of the case. For example, the case can be attached to a back surface of the computing device, opposite a flat panel display of the computing device. The case can include a flexible region that includes at least one spring and/or at least one flexible layer. The flexible region can act to resist bending of the case and thereby overcome at least some of the static load of the computing device when the case and the computing device are resting on a surface. As an angle of the flexible region is increased or decreased, a torsional load on the flexible region is also increased or decreased, thereby increasing or decreasing a resistive force of the flexible region. In this way, the resistive force can assist in canceling out at least a portion of the static load. As a result, the computing device and the case can be arranged in multiple positions without the static load completely overcoming a force of friction provided by the surface on which the computing device and the case reside. 
     In some embodiments, the case can include a back cover for attaching to the back surface of the computing device opposite the flat panel display, and a front cover that extends around a side of the computing device and at least partially covers the flat panel display. A portion of the back cover of the case can include a first flexible region. Additionally, an area between the front cover and the back cover can include a second flexible region. Furthermore, an inside surface of the front cover, relative to the computing device, can define a surface that can receive a static load of the computing device when the case is arranged as a stand. Each of the first flexible region and the second flexible region can include at least one spring and/or at least one flexible layer. Furthermore, each of the first flexible region and the second flexible region can be arranged to cancel out at least a portion of the dynamic loads experienced by the computing device, while also canceling out a portion of the static load of the computing device. For example, the second flexible region can be arranged to cancel out more of the static load of the computing device than the first flexible region, and the first flexible region can be arranged to cancel out more of the dynamic loads than the second flexible region. Such arrangements can be accomplished by varying the tension of one or more components that make up the first flexible region and the second flexible region. Furthermore, such arrangements can be accomplished by varying an amount of friction at a surface of the case on which the static load of the computing device resides when in a standing position. Additionally, depressions can be formed into areas of the case for an edge of the computing device to rest in when the case is acting as a stand. 
     The flexible region can be disposed between two or more regions of the case and can be debossed at one or more surfaces of the case. In this way, any springs or flexible layers will be hidden from view when the case is enclosing the computing device. Alternatively, one or more surfaces of the case defining the flexible region can remain without a debossed area over the flexible region. The flexible region can include one or more polymer layers, composite layers, and/or metal layers. Furthermore, the flexible region can be arranged to limit creeping or other degradation of the materials of the case over time. In some embodiments, the case is debossed on one side of the case where one or more flexible regions are incorporated in order to preserve a cosmetically smooth surface on a side of the case that is not debossed. Each flexible region can be arranged to have a limited bend radius in order to prevent creases and other blemishes that can occur when bending the material(s) covering the case. For example, when the case is made from leather, imitation leather, polymer, and/or a composite material, creases in the case can become permanent over time thereby making the case weaker and prone to environmental damage. Therefore, limiting the bend radius can mitigate cosmetic artifacts that can eventually compromise the integrity of the case. 
     The case can be attached to the computing device by incorporating one or more rigid or flexible magnets into a region of the computing device that is to be attached the computing device, such as the front surface, the back surface, and/or a region between the front surface and the back surface. In some embodiments, the case can incorporate a rigid frame that wraps at least partially around one or more edges of the computing device in order to maintain the computing device against one or more sides of the case. In yet other embodiments, the case can merely rely on surface friction directly between the case and the computing device to ensure that the computing device remains within the case when the case is at least partially enveloping the computing device. The case can incorporate one or more shims for improving the structural rigidity of the case at the back cover and/or front cover of the case. In some embodiments, the front cover of the case can remain flexible (even without a flexible element), thereby allowing the front cover to fold away, similar to a paperback book cover or magazine cover. The case can include conductive pathways embedded within the case in order to communicate signals to and from the computing device. For example, the case can include a keyboard, speakers, microphone, touch pad, camera, and/or any electrical component suitable for communicating with a computing device. Signals from the electrical components can be relayed through the conductive pathways in the case and arrive at the computing device. Such electrical components can be powered by an external power source relative to the case (e.g., the battery of the computing device attached to the case or a power plug attached to an electrical outlet and the case). Alternatively, the electrical components can be powered by an inductive power source that transmits wireless power signals to an inductor embedded in the case. The inductive power source can be attached to one or more electrical components embedded in the computing device. 
     These and other embodiments are discussed below with reference to  FIGS. 1A-9 . 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. 1A  illustrates a front perspective view a device cover  100  for positioning a computing device  102  into a position suitable for viewing a display  104  of the computing device  102 . The computing device  102  may include a tablet computing device, or a mobile communication device, such as a smartphone. The display  104  is designed to prevent visual information to a user in the form of textual information, still images, and/or video. Also, the display  104  may include a touch-sensitive layer that allows the display  104  to receive touch inputs used to provide a control or command to the display  104 . The computing device  102  may further include an enclosure  106  that receives the display  104  and several internal components (not shown), such as processor circuits, memory circuits, speakers, and batteries, as non-limiting examples. The enclosure  106  may include a metal, such as aluminum. In order to support the computing device  102 , the device cover  100  may include multiple sections. For example, the device cover  100  may include a first back cover  108  and a second back cover  110 . The first back cover  108  and the second back cover  110  may combine to support the computing device  102 . For example, the first back cover  108  and the second back cover  110  can provide support for the computing device  102  when the computing device  102  is receiving a touch input at the display  104 . Also, the device cover  100  may include a front cover  112  positioned below the computing device  102 . The front cover  112  may include a bumper  114  designed to engage the computing device  102 . Due in part of the arrangement of the device cover  100 , the bumper  114  defines the only position that the device cover  100  can be arranged to support the computing device  102  in an upright position, as shown in  FIG. 1A . 
       FIG. 1B  illustrates a rear perspective view of the device cover  100  shown in  FIG. 1A . As shown, the first back cover  108  is pivotally connected to the second back cover  110  such that the first back cover  108  may rotate with respect to the second back cover  110 , and vice versa. Also, the front cover  112  pivotally connected to the second back cover  110  such that the second back cover  110  may rotate with respect to the second back cover  110 , and vice versa. 
     The arrangement of the computing device  102  and the device cover  100  illustrated in  FIGS. 1A and 1B  is the only arrangement where this is possible. For example, if the computing device  102  was not resting against the bumper  114  (shown in  FIG. 1A ), the computing device  102  may tip over and cause both the first back cover  108  and the second back cover  110  to collapse in response to a touch input at the display  104 . This is in part due to a lack of components in the device cover  100  that can create a torsional force and resist static and dynamic loads exhibited by the computing device  102  when the computing device  102  is at least partially upright. 
       FIG. 2A  illustrates a front perspective view of an embodiment of a case  200 , in accordance with some described embodiments. As shown, the case  200  may couple with and support the computing device  102 . Further, the case  200  is designed to resist static loads (such as the weight of the computing device  102 ), as well as dynamic loads (including touch inputs to the display  104 ). Each of these loads may be exerted on the case  200  as a result of the computing device  102  being positioned in an at least partially upright position, as shown in  FIG. 2A . 
     The case  200  can include a front cover  212  that includes an interior surface  214  that can be made from material that provides some amount of friction to resist the movement of an edge of the computing device  102  in contact with the interior surface  214 , as shown in  FIG. 2A . Additionally, the case  200  can include one or more covers that can act as a stand for the computing device  102  when the computing device is arranged in an at least partially upright position. For example, the case  200  can include a first back cover  208  and a second back cover  210  connected with the first back cover  208 , with the first back cover  208  and the second back cover  210  supporting the computing device  102 . 
     The second back cover  210  may be pivotally coupled with the front cover  212 . Although not shown, the front cover  212  is design to rotate with respect to the second back cover  210  such that the front cover  212  can be positioned over the computing device  102 , and in particular, the display  104 . The case  200  may include several flexible elements embedded in the second back cover  210  and the front cover  212 . For example, the case  200  may include a first torsional element  216 , a second torsional element  218 , and a third torsional element  220 . As shown in the enlarged view, the first torsional element  216  may resemble a spring with a first end  222  and a second end  224  embedded in the front cover  212  and the second back cover  210 , respectively. The first torsional element  216  can include springs made from a metal or plastic, and having at least two ends that terminate in a substantially straight orientation. The second torsional element  218  and the third torsional element  220  may include any feature(s) described for the first torsional element. Also, the first torsional element  216 , the second torsional element  218 , and the third torsional element  220  may represent a first flexible region (between the second back cover  210  and the front cover  212 ) of the case  200 . 
     The aforementioned torsional elements may combine to cancel out at least some, and in some cases all, of the static and dynamic loads associated with the computing device  102 . Also, at least a portion of the torsional elements can be disposed within the case  200  such that the torsional elements are hidden from the sight of a user. For example, a layer of material such as leather, imitation leather, composite material, rubber, and/or any other material suitable for attaching to a case (such as the case  200 ) can be disposed around the case  200  to at least partially envelope the case  200 . The layer of material can be attached to the first back cover  208 , the second back cover  210 , and/or the front cover  212 . 
       FIG. 2B  illustrate a rear perspective view of the case  200  shown in  FIG. 2A , showing additional torsional elements of the case  200 . As shown, the case  200  may include torsional elements that extend into the first back cover  208  and the second back cover  210 . For example, the case  200  may include a first torsional element  236 , a second torsional element  238 , and a third torsional element  240 , with each of the torsional elements extending into both the first back cover  208  and the second back cover  210 . Similar to the torsional elements extending into both the second back cover  210  and the front cover  212 , the first torsional element  236 , the second torsional element  238 , and the third torsional element  240  may combine to cancel out at least some, and in some cases all, of the static and dynamic loads associated with the computing device  102 . Also, the layer(s) of material that cover the include the first torsional element  216 , the second torsional element  218 , and the third torsional element  220  may also cover the first torsional element  236 , the second torsional element  238 , and the third torsional element  240 . Also, the first torsional element  236 , the second torsional element  238 , and the third torsional element  240  may represent a second flexible region (between the first back cover  208  and the second back cover  210 ) of the case  200 . 
       FIG. 3A  is a front perspective of an embodiments of a case  300 , in accordance with some described embodiments. The case  300  may include any material(s) or feature(s) previously described for the case  200 , shown in  FIGS. 2A and 2B . As shown, the case  300  may include a first back cover  308 , a second back cover  310 , and a front cover  312 . Further, in order to secure the computing device  102  with the case, the first back cover  308  may include latching elements, such as a first latching element  344  and a second latching element  346 . However, the number of latching elements may vary. Also, the case may include multiple torsional elements that form flexible regions, with the torsional elements designed to support the computing device  102 . This will be discussed below. 
     The case  300  is designed to support the computing device  102 , even when the computing device  102  is at least partially upright, as shown in  FIG. 3A . For instance, a user may provide a touch input that results in a touch force  354  against the computing device  102  and specifically, against the display  104 . At least a portion of the touch force is transferred to the front cover  312  and to each of the first back cover  308  and the second back cover  310 . In order to at least partially or fully cancel the touch force, the case  300  includes a flexible region. As shown in  FIG. 3A , the case  300  includes a first torsional element  316 , a second torsional element  318 , and a third torsional element  320 , each of which may extend into both the second back cover  310  and the front cover  312 . These torsional elements may define in part a joint of a flexible region between the second back cover  310  and the front cover  312 , and may include any material or feature previously described for a torsional element. 
     The case  300  may include an additional flexible region. For example,  FIG. 3B  illustrates a rear isometric view of the case  300  shown in  FIG. 3A , further showing additional torsional elements, such as a first torsional element  336 , a second torsional element  338 , and a third torsional element  340 . These torsional elements may define in part a joint at the additional flexible region between the first back cover  308  and the second back cover  310 , and may include any material or feature previously described for a torsional element. The flexible region between the first back cover  308  and the second back cover  310  create a first torsional force  360  (also shown in  FIG. 3A ) that can cancel out at least a portion of the touch force  354 . Furthermore, when the computing device  102  is at least partially upright, a static force  356  from the weight of the computing device  102  can be transferred to the first back cover  308 , the second back cover  310 , and the front cover  312 . In order to at least partially cancel the static force  356  (also shown in  FIG. 3A ), the flexible region connected at a joint between the front cover  312  and the second back cover  310  can provide a second torsional force  362 . The second torsional force  362  can at least partially or fully cancel the static force  356 , thereby allowing the computing device  102  to be arranged in nearly an unlimited number of angles relative to an interior surface  314  of the front cover  312 . For example, the computing device  102  can be arranged at a 90-, 65-, 45-, and 15-degree angle, as non-limiting examples, relative to the interior surface  314  without the static force  356  overcoming the second torsional force  362  and causing the first back cover  308  and the second back cover  310  to collapse. Furthermore, because the first torsional force  360  cancels out a majority of the touch force  354 , a user can interact with the display  104  (shown in  FIG. 3A ) at any angle of the computing device  102  without having to worry about the computing device  102  falling down. In some embodiments, in order to mitigate any opportunity for the computing device  102  to overcome a force of friction  364  (also shown in  FIG. 3A ) provided by the interior surface  314 , the surface friction of the interior surface  314  can be increased. For example, the surface friction of the interior surface  314  can be higher than an exterior surface friction of the case  300  in order to provide a smoother surface on an exterior of the case  300  compared to the interior surface  314 . 
       FIG. 4A  illustrate a front perspective view of an embodiment of a case  400  that includes alternate flexible regions, in accordance with some described embodiments. As shown, the case  400  may include a first back cover  408  and a second back cover  410 , with a first flexible region  422  defining a joint between the first back cover  408  and the second back cover  410 . The case  400  may include a front cover  412  connected with the second back cover  410 , with a second flexible region  424  defining a joint between the second back cover  410  and the front cover  412 . Each of the first flexible region  422  and the second flexible region  424  can incorporate one or more flexible layers (shown as dotted lines) for supporting the computing device  102  in one or more upright arrangements. For example, the first flexible region  422  can create a first torsional force  466  that at least partially cancels a touch force  454  that can be provided by a user at the display  104 . Additionally, the second flexible region  424  can create a second torsional force  460  that at least partially cancels a static force  456  created in part by a weight of the computing device  102 . In this way, a user is able to fold the case  400  into any suitable arrangement for supporting the computing device  102  in an upright position without having to worry about a touch force  454  or touch gesture causing the computing device  102  to move or collapse. Furthermore, an interior surface  414  of the front cover  412  can include a surface made from a material that creates a force of friction  470  that prevents the computing device  102  from slipping across the interior surface  414 . 
       FIG. 4B  illustrates a rear isometric view of the case  400  shown in  FIG. 4A . As shown, the first flexible region  422  can extend across (and between) the first back cover  408  and the second back cover  410 , while the second flexible region  424  can extend across (and between) the second back cover  410  and the front cover  412 . Although a discrete number of flexible regions is shown, in some embodiments, the case  400  can have more than two flexible regions. For example, the case  400  can have at least two non-parallel flexible regions disposed within the case  40 . Also, in some embodiments, the case  400  includes a magnet  428  disposed within the first back cover  408 . The magnet  428  may be used to secure the computing device  102  with the case  400  by way of magnetic attraction between the magnet  428  and a magnetic element or magnetically attractable material (not shown) disposed in the computing device  102 . Any of the magnets discussed herein can include particles of neodymium, niobium, iron, and/or any other rigid or flexible magnetic material. Also, although not shown, the first back cover  408  may include two or more magnets. Also, although not shown, the second back cover  410  may include a magnet that magnetically couples with a magnetic element or magnetically attractable material (not shown) disposed in the computing device  102 . 
     The case  400  can include one or more layers of leather, imitation leather, microfiber, composite, plastic, rubber, metal, and/or any other material suitable for forming into a case for a computing device. One or more layers of flexible material can be disposed within the case  400  to create the first flexible region  422  and the second flexible region  424 . The first flexible region  422  and/or the second flexible region  424  can be debossed on one or more sides of the case  400  where the first flexible region  422  and/or the second flexible region  424  reside. Further description of the flexible region is described herein, especially respect to  FIG. 5 , which illustrates a cross sectional view of the first flexible region  422  taken from a cross sectional cutaway  426  of the case  400  along the first flexible region  422 . 
       FIGS. 5A-5D  illustrate cross sectional views corresponding to the flexible regions discussed herein. For example, the cross sectional views shown and described in  FIGS. 5A-5D  can correspond to a cross section of the first flexible region  422  identified at the cross sectional cutaway  426  of  FIG. 4B . However, it should be noted that the cross sectional views can correspond to any of the flexible regions, such as the second flexible region  424  (shown in  FIGS. 4A and 4B ), described with respect to any of the cases discussed herein. 
       FIG. 5A  illustrates a cross sectional view of a flexible region  500  of a case. The flexible region  500  can include a first layer  502  that can be made from leather, imitation leather, microfiber, plastic, metal, and/or any other material for forming a case. The flexible region  500  can also include a second layer  504  that can be made from the same material as the first layer  502  or a different material. For example, the first layer  502  can be made from leather or imitation leather, and the second layer  504  can be made from a microfiber or synthetic material. The first layer  502  can correspond to an outer layer that is most visible to a user of a case (such as the case  400  shown in  FIG. 4A ) and a computing device (such as the computing device  102  shown in  FIG. 4A ). The second layer  504  can be a layer that abuts a computing device when the computing device is disposed with the case corresponding to the flexible region  500 . Also, the first layer  502  and the second layer  504  can also include a first embossed portion  506  and a second embossed portion  508 , respectively. The first embossed portion  506  may separate a first panel  510  from a second panel  512  (both used to form a case), while the second embossed portion  508  may separate a third panel  514  from a fourth panel  516  (both used to form a case). Also, the flexible region  500  may further include a flexible component  518 . The flexible component  518  can be made from any material suitable for acting as a spring or flexible joint between two panels. For example, the flexible component  518  can be made from any material that exhibits some amount of tension and can form back into an original shape after experiencing some amount of tension. Such materials can include plastic, rubber, foam, elastomer, metal, and/or any other synthetic or non-synthetic material. In some embodiments, the flexible component  518  can span an entire width of each of the aforementioned panels or only between portions of the panels. In yet other embodiments, the flexible component  518  is not disposed between the panels and is only disposed between the first embossed portion  506  and the second embossed portion  508 . 
       FIG. 5B  illustrates another embodiment of a flexible region  520  that can be included in any of the cases described herein. The embodiment of  FIG. 5B  includes a first layer  522  and a second layer  524 , similar to the first layer  502  and the second layer  504 , respectively, described with respect to  FIG. 5A . However, in  FIG. 5B , only the second layer  524  includes a debossed portion  528 . Additionally, the flexible region  520  includes panels, such as a first panel  530  and a second panel  532 , only between the second layer  524  and a flexible component  538 , which may include any material(s) previously described for the flexible component  518  (shown in  FIG. 5A ). Further, the debossed portion  528  in the second layer  524  may define a hinge between the first panel  530  and the second panel  532 . The first panel  530  and the second panel  532  can be defined by one or more plastic or metal shims disposed within a case (such as the case  400 , shown in  FIG. 4A ). The first panel  530  and the second panel  532  can be adhered or molded to the flexible component  538 . Furthermore, the flexible component  538  can be formed as a single piece with the first panel  530  and the second panel  532 , such that the flexible component  538  is a less thick region compared to the first panel  530  and the second panel  532 . 
       FIG. 5C  illustrates yet another embodiment of a flexible region  540  that can be included in any of the cases described herein. The embodiment of  FIG. 5C  includes a first layer  542  and a second layer  544 , similar to the first layer  502  and the second layer  504 , respectively, described with respect to  FIG. 5A . However, the first layer  542  and the second layer  544  in  FIG. 5C  may not include a debossed portion. In this way, a cosmetically smooth and flat surface can be seen on both sides of the flexible region  540 . Additionally, the flexible region  540  can include a first panel  550  and a second panel  552  that combine (with the first layer  542  and the second layer  544 ) to surround a flexible component  558 . The flexible component  558  can be made from the same material as the flexible component  518  of  FIG. 5A . However, the flexible component  558  can have distal ends that are disposed adjacent to distal ends of the first panel  550  and the second panel  552  in order to create a surface of uniform thickness over the flexible region  540 . Alternatively, the flexible component  558  can be configured to at least partially reside within a portion of the first panel  550  and/or the second panel  552  in order to lock the flexible component  558  in place. 
       FIG. 5D  illustrates another embodiment of a flexible region  560  that can be included in any of the cases described herein. The flexible region  560  may include a first layer  562  and a second layer  564 , similar to the first layer  502  and the second layer  504 , respectively, described with respect to  FIG. 5A . The flexible region  560  may further include a first panel  570  and a second panel  572  that combine (with the first layer  562  and the second layer  564 ) to surround a frictional layer  576  and the flexible component  578 . The flexible component  578  can act as an elastic joint between the first panel  570  and the second panel  572 . The frictional layer  576  can act as a clutch that can bend into any angle and resist deformation out of an angle into which the frictional layer  576  is bent. The frictional layer  576  can be a clutch assembly that includes at least one joint that resists rotation but allows for some amount of rotation. In this way, the flexible region  560  can be deformed or rotated into any angle while still resisting some amount of static and/or dynamic loads exerted by a computing device (such as the computing device  102 , shown in  FIG. 4A ) at any angle of the computing device. In some embodiments, the frictional layer  576  can be made from a plastic, metal, and/or any other material that can bent from a flat position into an angled position, and resist deformation once in the angled position. In this way, the flexible region  560  can be bent into an angled position, such as the position of the first flexible region  422  (shown in  FIG. 4B ), and counteract dynamic loads (e.g., the touch force  454 , shown in  FIG. 4B ), and also be bent into a flat position, such as the position of the front cover  412  of the case  400  ( FIG. 4B ), and resist bending out of the flat position. In some embodiments, when the flexible region  560  is in the angled position and/or in the flat position, a static force of the frictional layer  576  can be greater than a static force of the flexible component  578 . As a result, the flexible region  560  can remain, or tend to remain, in any shape or angle corresponding to the frictional layer  576 . The flexible region  560  can be incorporated into the case  400  (shown  FIGS. 4A and 4B ) at the first flexible region  422  and/or the second flexible region  424 , to assist in counteracting both static and dynamic loads exerted by the computing device  102 . 
       FIG. 6A  illustrates a front perspective view of an embodiment of a case  600  that is attached to a back surface of the computing device  102 , with the back surface opposite the display  104 , in accordance with some described embodiments. The case  600  can include a first portion  608  that includes one or more panels and a second portion  610  that also includes one or more panels. The case  600  may further include a flexible region  620  disposed between the first portion  608  and the second portion  610 . The flexible region  620  can include one or more springs as discussed herein, and/or one or more layers of flexible material that act as a spring embedded between layers that define the first portion  608  and the second portion  610 . 
       FIG. 6B  illustrates a rear isometric view of the case  600  shown in  FIG. 6A . The flexible region  620  can provide a torsional force  662  (also labeled in  FIG. 6A ) that can at least partially cancel a touch force  654  (also labeled in  FIG. 6A ) that is carried through the computing device  102  to the case  600  when a user touches the display  104  (shown in  FIG. 6A ). By canceling out the touch force  654 , a user is able to arrange the case  600  such that the case  600  positions the computing device  102  upright without concern for the computing device  102  tipping over when the user is tapping on the display  104 . Furthermore, the torsional force  662  can at least partially cancel a static force  656  exhibited by the computing device  102  due to the weight of the computing device  102 . In this way, a first frictional force  658  and/or a second frictional force  660  (also labeled in  FIG. 6A ) need not be primarily relied upon for maintaining an angle of the computing device  102  relative to a surface on which the computing device  102  and the case  600  are resting. As a result, the case  600  and the computing device  102  can be placed on nearly any surface and maintain any configuration while receiving reasonable touch input forces from a user. 
       FIG. 7  illustrates a perspective view of an embodiment of a case  700  that can include one or more flexible regions and conductive pathways for operating electrical components embedded in the case  700 , in accordance with some described embodiments. The case  700  can include a first back cover  708  and a second back cover  710 . The case  700  can further include a front cover  712  that acts as a support for the computing device  102  when the computing device  102  is arranged in an at least partially upright position, as shown in  FIG. 7 . The case  700  may further include a first flexible region  722  disposed between the first back cover  708  and the second back cover  710 , as well as second flexible region  724  disposed between the second back cover  710  and the front cover  712 . Each of the first flexible region  722  and the second flexible region  724  can be understood and modified according to any of the embodiments provided herein. 
     The case  700  can also include a conductive pathway  730  created by one or more flexible conductive layers disposed within the case  700 . The conductive pathway  730  can extend through the first flexible region  722  and/or the second flexible region  724 . Additionally, the conductive pathway  730  can connect (which may include an electrical connection) to the computing device  102  at one or more edges of the computing device  102 , or a back surface of the computing device  102 . The case  700  can be adhered to the computing device  102 , magnetically coupled to the computing device  102 , or otherwise attached to the computing device  102  by way of friction between the computing device  102  and the case  700 . Electrical signals traveling through the case  700  can be wirelessly transmitted between inductors located in the computing device  102  and the case  700 . In some embodiments, the case  700  may include a keyboard  732  embedded in the case  700  and electrically coupled to the conductive pathway  730 . In this way, a user can type on the keyboard  732  and control applications executing on the computing device  102  by way of signals traveling via the conductive pathway  730 . The keyboard  732  can receive power by the computing device  102 , by way of an internal power supply (not shown), or battery, within the computing device  102 . Alternatively, the case  700  may include an internal power supply (not shown). Still, as an additional alternative, an auxiliary power supply (not shown) connected to the case  700  and an external power source, such as an outlet or another computing device. In some embodiments, the case  700  can include electrical components in place of or in addition to the keyboard  732 . For example, such electrical components can include a speaker, microphone, wireless transmitter, touch pad, heating pad or cooling pad, camera, processor, radio-frequency identification (RFID) tag, and/or any other electrical component. 
       FIG. 8A  illustrates a front perspective view of an embodiment of a case  800  that includes magnets for creating a magnetic trough in which the computing device  102  can hover above as a result of magnetic repulsion and at least one or more flexible regions of the case  800 . The case  800  can include a panel  802  that is connected to at least a first back cover  808  and/or a second back cover  810  of the case  800 . The case  800  may further include a front cover  812 . The case  800  may further include a first flexible region  822  disposed between the first back cover  808  and the second back cover  810 , as well as second flexible region  824  disposed between the second back cover  810  and the front cover  812 . Also, the front cover  812  may include a first magnetic assembly  830  that includes one or more magnets (shown as dotted lines). The first magnetic assembly  830  will be further discussed below. Also, the first magnetic assembly  830  may be hidden by the front cover  812 . 
       FIG. 8B  illustrates a front perspective view of the case  800  shown in  FIG. 8A , with the computing device  102  removed from the case  800 . Also, a bottom portion of the front cover  812  is removed for purposes of illustration. As shown, the panel  802  can include a second magnetic assembly  832  that includes one or more magnets designed to magnetically repel the magnets of the first magnetic assembly  830  disposed in the front cover  812 . The first magnetic assembly  830  and the second magnetic assembly  832  can be arranged such that their respective external magnetic fields are pointing in substantially the same direction. For example,  FIG. 8B  illustrates a magnetic field view  816  that provides a simplified view of an arrangement of the magnetic fields created by the first magnetic assembly  830  and the second magnetic assembly  832 , when the second magnetic assembly  832  hovers over the first magnetic assembly  830 . The first magnetic assembly  830  can create a first magnetic field  842  and second magnetic assembly  832  can create a second magnetic field  844 . Because the first magnetic field  842  and the second magnetic field  844  are arranged in similar directions (as indicated by the “x,” which is provided to resemble the back of an arrow that points in the direction of the magnetic field vector lines), the first magnetic assembly  830  and the second magnetic assembly  832  will repel each other by way of a magnetic repulsion force  840  (also shown in  FIG. 8A ). Furthermore, because the case  800  includes a first flexible region  822  and a second flexible region  824  that can at least partially cancel out a static load  856  (shown in  FIG. 8A ) created by a weight of the computing device  102 , the magnetic repulsion force  840  will cause the computing device  102  to hover over the first magnetic assembly  830 , which acts as a magnetic trough. The first magnetic assembly  830  can be arranged such that at least two magnets extend parallel to an edge of the computing device  102  nearest the first magnetic assembly  830  when the computing device  102  is arranged over the front cover  812 . In some embodiments, at least three of first magnetic assembly  830  can be arranged within the front cover  812 , and at least two of magnets of the first magnetic assembly  830  can have different size magnetic fields. For example, a magnet of the first magnetic assembly  830  can be arranged between two larger magnets of the first magnetic assembly  830  to create a magnetic trough for an edge of the computing device  102  to reside and hover above. A distance by which the computing device  102  can hover above the front cover can be one or more millimeters, centimeters, or inches in some embodiments. 
       FIG. 9  illustrates a flowchart  900  showing a method for forming a case, in accordance with some described embodiments. In this regard, the case may include any case discussed herein. The method can be performed by a computing device or any apparatus suitable for performing manufacturing operations. Furthermore, the method can be modified according to any of the embodiments discussed herein. The method can include a step  902  of disposing a flexible component between at least two panels. The flexible component can be a spring or flexible layer of material that acts as a spring. The two panels can be set against, adhered to, or formed to the flexible component. 
     The method can further include a step  904  of covering opposing sides of the flexible component and the at least two panels with a cover material. The cover material can include leather, imitation leather, microfiber, rubber, plastic, metal, and/or any other suitable cover material. Furthermore, different types of materials can be connected to different sides of the two panels and the flexible component. 
     The method can also include an optional step  906  of debossing a portion of the cover material where the flexible component resides. Debossing can be performed using pressure and/or heat in order to create depression in the cover material where the flexible component resides. 
     In some embodiments a case is set forth that includes at least two cover portions configurable as a stand for the computing device. The case can also include a flexible region between the at least two cover portions. The flexible region can be configured to provide a torsional force that counteracts at least some amount of static weight of the computing device when the at least two cover portions are configured as the stand. The flexible region can be configured to counteract a static force exerted by the computing device using a torsional force exerted by the flexible region, and the torsional force exerted by the flexible region can increase as the static force exerted by the computing device increases. The static force exerted by the computing device can change based on an angle of the computing device relative to a surface on which the cover portions and the computing device are capable of resting. The flexible region can include one or more springs configured to provide the torsional force. The case can also include a secondary flexible region disposed within a cover portion of the at least two cover portions, wherein the cover portion includes a first cover and a second cover, and the secondary flexible region is disposed between the first cover and the second cover. Furthermore, the secondary flexible region can be configured to provide a secondary torsional force that counteracts dynamic forces associated with a touch input at the computing device when the at least two cover portions are configured as the stand. Additionally, the flexible region can include one or more layers of a flexible elastomer material, and the one or more layers of flexible elastomer material can extend into at least a portion of a cover of the at least two cover portions. The cover can be debossed at a region of the cover that includes the one or more layers of flexible material. The at least two cover portions include at least one of a leather layer, an imitation leather layer, a microfiber layer, a metal layer, and/or a combination thereof. 
     In other embodiments, a case configurable as a stand for a computing device is set forth. The case can include a first cover comprising a first flexible region and at least one cover layer disposed over the first flexible region; and a second cover connected to the first cover by at least a second flexible region. The first flexible region and the second flexible region can be configured to provide torsional forces that counteract a weight of the computing device when the first cover and the second cover are arranged as the stand for the computing device. The first flexible region and/or the second flexible region include an elastic joint configured to counteract the weight of the computing device and a frictional joint configured to counteract dynamic loads exerted by the computing device. The first cover can include one or more magnets for attaching the first cover to the computing device. The at least one cover layer can include at least one debossed region over a portion of the first flexible region. Additionally, the first cover can include at least two panels disposed on opposite sides of the first flexible region. Furthermore, a panel of the at least two panels can be configured to extend away from the computing device when the first cover and the second cover are arranged as the stand for the computing device. A torsional force of the first flexible region can be configured to counteract user input forces at a touch screen of the computing device when the first cover and the second cover are arranged as the stand. The torsional forces can include a first torsional force that acts in a first radial direction, and a second torsional force that acts in a second radial direction opposite the first radial direction. 
     In yet other embodiments a system is set forth. The system can include a device cover configurable as a stand and a protective cover for a computing device; and at least one flexible component disposed within the device cover such that the at least one flexible component provides a torsional spring force that counteracts a standing weight and dynamic mechanical loads of the computing device when the device cover is configured as a stand. The at least one flexible component can include a first flexible component arranged adjacent to an edge of the computing device when the device cover is configured as the protective cover, and a second flexible component arranged over a surface of the computing device when the device cover is configured as the protective cover. The device cover can include at least one single layer of material that conceals and extends over both of the first flexible component and the second flexible component. Furthermore, the first flexible component and the second flexible component can be configured to provide opposing torsional spring forces in opposing radial directions when the device cover is arranged as the stand for the computing device. Additionally, an interior surface of the device cover can be configured to support an edge of the computing device when the device cover is configured as the stand and the computing device is arranged at any angle between 90 and 30 degrees relative to the interior surface.
