     BACKGROUND 
     Field of the Invention 
     The present disclosure relates to cases for portable electronic devices. 
     Description of the Related Art 
     Portable electronic devices, such as smartphones, tablets, laptops, and the like are known to sustain damage from impact and from contamination as a result of the ingress of water or other fluids. Such damage may result, for example, in a cracked screen, scratches on a finished surface, lost or damaged buttons or controls, cracked or bent external body components, and/or failed or malfunctioning electrical components. Some types of damage may be merely cosmetic (e.g., scratches). However, other types of damage may ruin or limit the functionality of the device. Such devices often contain sensitive and fragile components (e.g., a screen, a camera lens, processors, storage drives, accelerometers, and sensors). Accidentally dropping the device could render various features unusable. 
     Protective cases can protect portable electronic devices from such damage and other types of damage. Thus there remains a continuing need for new and improved protective cases for portable electronic devices. 
     SUMMARY 
     A hybrid frame sleeve case for a portable electronic device is disclosed herein. The portable electronic device may be a laptop computer, a tablet, or another portable electronic device. The case may include flexible panels, such as neoprene or fabric panels, attached to an elastic polymer frame, such as ethylene vinyl acetate (EVA). The elastic polymer frame extends around a perimeter of the sleeve to provide cushioning or padding for the side edges of the sleeve. A magnetic latch or other latch may be used to secure an opening on one side of the sleeve. 
     A sleeve case may preferably have a rectangular shape, with two longer sides and two shorter sides, and rounded corners. The sleeve may have an opening on one of the shorter sides of the sleeve or alternatively may have an opening on one of the longer sides of the sleeve. This opening may be secured by a magnetic latch. The sleeve may include front and back neoprene panels. These may be attached to an elastic polymer or rubber frame (e.g., EVA frame) by stitching, glue, epoxy, welding, fusing, or another suitable technique. The frame preferably extends along all sides of the sleeve, thereby providing cushioning and protection for the sides of the case. 
     In some embodiments, the elastic polymer frame may be formed by injection molding. 
     In some embodiments, the disclosed case includes: a frame structure including a frame border having an exterior edge and interior edge, where the exterior and interior edges separated by a frame border width, where the frame structure comprises a first material, and where the interior edge surrounds a perimeter of a compartment for the portable electronic device; a first side panel, attached to a first side of the frame border, where the first side panel includes a second material that is different from the first material, where the first material is more shock absorbing than the second material; and a second side panel, attached to a second side of the frame border, where the second panel includes the second material. 
     In some embodiments, the sides of the portable electronic device may be cushioned against side impacts by the first material having a thickness of the frame border width. A thicker frame border will provide greater shock absorbing capability but will also increase the overall size of the case. The first material may be foam rubber. Alternatively, the first material may be ethylene vinyl acetate and the second material may be neoprene. 
     In some embodiments, the case includes an ethylene vinyl acetate (EVA) frame that includes: a first side, a second side, a third side, and a fourth side, where the first side is adjacent to the second and fourth sides, and opposite to the third side, the second side is adjacent to the first and third sides, and opposite to the fourth side, and the second side is longer than the first side. A cross section of the second side includes a first portion extending in a first direction and a second portion extending in a second direction that is transverse to the first direction. The first portion includes an exterior side and an interior side, and the first portion has a first length from a first end to a second end in the first direction. The second portion is attached to the interior side of the first portion at a point between the first and second ends and extends in the second direction away from the first portion a second length. 
     The case includes a compartment, enclosure, or space formed by the first, second, third, and fourth sides, where first and third sides of the compartment are bounded by the first and third sides that extend in the second direction. Second and fourth sides of the compartment are bounded by the second and fourth sides that extend a third direction that is transverse to the second direction. 
     In some embodiments, the case includes a first neoprene panel that is attached (e.g., via stitching or an adhesive) to a first side of the EVA frame. In such embodiments, the case also includes a second neoprene panel that is attached to a second side of the EVA frame. The second side of the EVA frame is opposite to the first side, and the compartment (which will hold the device to be protected by the case) is bounded on opposite sides by the first and second neoprene panels. 
     In various embodiments, the second length is greater than the first length. A cross section of the first side includes a third portion extending in the first direction and a fourth portion extending in a third direction that is transverse to the first direction. The third portion includes an exterior side and an interior side. The fourth portion is attached to the interior side of the third portion at a point between the third and fourth ends, and extends in the third direction away from the third portion a third length. The third length may be greater than the second length. 
     The fourth portion may include a recessed region that may be shaped to hold a magnet. The third portion has a fourth length from a third end to a fourth end in the first direction, and the fourth length may be greater than the first length or, alternatively, the fourth length may be the same as the first length. 
     The compartment is an enclosed space that retains (and protects) a portable electronic device. The case may include a latch that includes a first latch component and a second latch component, where the first latch component may be attached to the second neoprene panel and the second latch component may be attached to the first side of the EVA frame, and where the second latch component is adapted to mate with the first latch component. The second latch component may alternatively be attached to the second side of the EVA frame. An opening to the compartment is open when the first and second latch components are separated. The opening to the compartment is closed when the first and second latch components are latched together. 
     In some embodiments, the latch may be a magnetic latch. A first magnetic latch component is attached to the second neoprene panel. A second magnetic latch component is attached to the EVA frame. An opening to the compartment is open when the first and second magnetic latch components are separated from each other. The opening to the compartment is closed when the first and second magnetic latches are latched together via magnetic attraction. 
     In some embodiments, the first neoprene panel is stitched to the first side of the EVA frame, and the second neoprene panel is stitched to the second side of the EVA frame. 
     A method of protecting a portable electronic device is also disclosed herein. The method includes: providing a frame structure for a portable electronic device having a frame border with an exterior edge and interior edge, where the frame structure is made of a first material; separating the exterior and interior edges by a frame border width; using the interior edge of the frame structure to surround a perimeter of a compartment for the portable electronic device; attaching a first side panel to a first side of the frame border, where the first side panel is made of a second material, different from the first material; and attaching a second side panel to a second side of the frame border, where the second panel is made of the second material, and the first material is more shock absorbing than the second material. The sides of the portable electronic device are cushioned against side impacts by the first material having a thickness that is approximately equal to the frame border width. 
     The disclosed case may be referred to as a sleeve, portfolio, a portable electronic device enclosure, wallet, container, folder, folding case, pocketbook, folding pocketbook, box, jacket, or envelope. The case may include one or more pockets. The pockets may be used to hold pens, pencils, papers, business cards, credit cards, money, accessories for the portable electronic device (e.g., charger, stylus), and so forth. A sleeve, frame, or both as described herein may be referred to as a portable electronic device holder, enclosure, container, or receptacle. 
     In some embodiments, the disclosed case further includes a charging system that includes a battery compartment that houses a rechargeable battery. The front face side panel has a cushioned flexible construction, while the opposing back face side panel has a semi-rigid outer panel construction that defines a battery compartment that houses a rechargeable battery. The rechargeable battery is electrically coupled to a plurality of interfaces that facilitate control and power to and from the battery. The interfaces include one or more internal electrical connectors mounted in the device compartment. The internal connectors are selected and positioned to electrically communicate with the portable electronic device and thereby facilitate charging of the device when the device is inserted in and protected by the case. The inclusion of multiple internal connectors allows for multiple connection points that are capable of connecting to the device when the device is inserted into the case, which for example would be capable of facilitating charging of the device regardless of whether the device is inserted into the case face-up or face-down. The electrical interfaces also include one or more external electrical connectors that are accessibly positioned on the outside of the case and that facilitate charging of one or more electronic devices that are located outside or external to the case as well as charging of the battery from a power source. A connector cable is provided to facilitate charging. A battery charge gauge and an activation button are also provided on the outside of the case to allow monitoring of the charge status of the rechargeable battery and to allow control over power to and from the case. A magnetic latch or other latch is used to secure an opening on one side of the case.

     A sleeve case may preferably have a rectangular shape, with two longer sides and two shorter sides, and rounded corners. The sleeve may have an opening on one of the shorter sides of the sleeve or alternatively may have an opening on one of the longer sides of the sleeve. This opening may be secured by a magnetic latch. The sleeve may include front and back neoprene panels. These may be attached to an elastic polymer or rubber frame (e.g., EVA frame) by stitching, glue, epoxy, welding, fusing, or another suitable technique. The frame preferably extends along all sides of the sleeve, thereby providing cushioning and protection for the sides of the case. 
     In some embodiments, the elastic polymer frame may be formed by injection molding. 
     In some embodiments, the disclosed case includes: a frame structure including a frame border having an exterior edge and interior edge, where the exterior and interior edges separated by a frame border width, where the frame structure comprises a first material, and where the interior edge surrounds a perimeter of a compartment for the portable electronic device; a first side panel, attached to a first side of the frame border, where the first side panel includes a second material that is different from the first material, where the first material is more shock absorbing than the second material; and a second side panel, attached to a second side of the frame border, where the second panel includes the second material. 
     In some embodiments, the sides of the portable electronic device may be cushioned against side impacts by the first material having a thickness of the frame border width. A thicker frame border will provide greater shock absorbing capability but will also increase the overall size of the case. The first material may be foam rubber. Alternatively, the first material may be ethylene vinyl acetate and the second material may be neoprene. 
     In some embodiments, the case includes an ethylene vinyl acetate (EVA) frame that includes: a first side, a second side, a third side, and a fourth side, where the first side is adjacent to the second and fourth sides, and opposite to the third side, the second side is adjacent to the first and third sides, and opposite to the fourth side, and the second side is longer than the first side. A cross section of the second side includes a first portion extending in a first direction and a second portion extending in a second direction that is transverse to the first direction. The first portion includes an exterior side and an interior side, and the first portion has a first length from a first end to a second end in the first direction. The second portion is attached to the interior side of the first portion at a point between the first and second ends and extends in the second direction away from the first portion a second length. 
     The case includes a compartment, enclosure, or space formed by the first, second, third, and fourth sides, where first and third sides of the compartment are bounded by the first and third sides that extend in the second direction. Second and fourth sides of the compartment are bounded by the second and fourth sides that extend a third direction that is transverse to the second direction. 
     In some embodiments, the case includes a first neoprene panel that is attached (e.g., via stitching or an adhesive) to a first side of the EVA frame. In such embodiments, the case also includes a second neoprene panel that is attached to a second side of the EVA frame. The second side of the EVA frame is opposite to the first side, and the compartment (which will hold the device to be protected by the case) is bounded on opposite sides by the first and second neoprene panels. 
     In various embodiments, the second length is greater than the first length. A cross section of the first side includes a third portion extending in the first direction and a fourth portion extending in a third direction that is transverse to the first direction. The third portion includes an exterior side and an interior side. The fourth portion is attached to the interior side of the third portion at a point between the third and fourth ends, and extends in the third direction away from the third portion a third length. The third length may be greater than the second length. 
     The fourth portion may include a recessed region that may be shaped to hold a magnet. The third portion has a fourth length from a third end to a fourth end in the first direction, and the fourth length may be greater than the first length or, alternatively, the fourth length may be the same as the first length.

The case may include a latch that includes a first latch component and a second latch component, where the first latch component may be attached to the second neoprene panel and the second latch component may be attached to the first side of the EVA frame, and where the second latch component is adapted to mate with the first latch component. The second latch component may alternatively be attached to the second side of the EVA frame. An opening to the compartment is open when the first and second latch components are separated. The opening to the compartment is closed when the first and second latch components are latched together. 
     In some embodiments, the latch may be a magnetic latch. A first magnetic latch component is attached to the second neoprene panel. A second magnetic latch component is attached to the EVA frame. An opening to the compartment is open when the first and second magnetic latch components are separated from each other. The opening to the compartment is closed when the first and second magnetic latches are latched together via magnetic attraction. 
     In some embodiments, the first neoprene panel is stitched to the first side of the EVA frame, and the second neoprene panel is stitched to the second side of the EVA frame. 
     A method of protecting a portable electronic device is also disclosed herein. The method includes: providing a frame structure for a portable electronic device having a frame border with an exterior edge and interior edge, where the frame structure is made of a first material; separating the exterior and interior edges by a frame border width; using the interior edge of the frame structure to surround a perimeter of a compartment for the portable electronic device; attaching a first side panel to a first side of the frame border, where the first side panel is made of a second material, different from the first material; and attaching a second side panel to a second side of the frame border, where the second panel is made of the second material, and the first material is more shock absorbing than the second material. The sides of the portable electronic device are cushioned against side impacts by the first material having a thickness that is approximately equal to the frame border width. 
     The disclosed case may be referred to as a sleeve, portfolio, a portable electronic device enclosure, wallet, container, folder, folding case, pocketbook, folding pocketbook, box, jacket, or envelope. The case may include one or more pockets. The pockets may be used to hold pens, pencils, papers, business cards, credit cards, money, accessories for the portable electronic device (e.g., charger, stylus), and so forth. A sleeve, frame, or both as described herein may be referred to as a portable electronic device holder, enclosure, container, or receptacle. 
     In some embodiments, the disclosed case further includes a charging system that includes a battery compartment that houses a rechargeable battery. The front face side panel has a cushioned flexible construction, while the opposing back face side panel has a semi-rigid outer panel construction that defines a battery compartment that houses a rechargeable battery. The rechargeable battery is electrically coupled to a plurality of interfaces that facilitate control and power to and from the battery. The interfaces include one or more internal electrical connectors mounted in the device compartment. The internal connectors are selected and positioned to electrically communicate with the portable electronic device and thereby facilitate charging of the device when the device is inserted in and protected by the case. The inclusion of multiple internal connectors allows for multiple connection points that are capable of connecting to the device when the device is inserted into the case, which for example would be capable of facilitating charging of the device regardless of whether the device is inserted into the case face-up or face-down. The electrical interfaces also include one or more external electrical connectors that are accessibly positioned on the outside of the case and that facilitate charging of one or more electronic devices that are located outside or external to the case as well as charging of the battery from a power source. A connector cable is provided to facilitate charging. A battery charge gauge and an activation button are also provided on the outside of the case to allow monitoring of the charge status of the rechargeable battery and to allow control over power to and from the case. A magnetic latch or other latch is used to secure an opening on one side of the case. 
       FIGS.  1 - 2    show an embodiment of the disclosed hybrid frame sleeve case. The case is a neoprene sleeve for a portable electronic device such as a laptop or tablet. The sleeve includes a neoprene front panel  108  and back panel (not shown), and an ethylene vinyl acetate (EVA) frame  112  along an edge of the sleeve. The EVA frame extends around the perimeter of the sleeve and provides additional protection for the contents of the case. The device slips in from one side of the sleeve, opened by using a tab  116  and closed using a magnetic latch (not shown). 
     The color of the frame may be a neon- or fluorescent-type color, such as a yellow or yellow-green color (alternatively referred to as lumen color). Neon colors for the frame will outline the case in a bright color, which allows the case to be more easily visible in low light or dark conditions. The frame may also be embedded with reflective material or glow-in-the-dark material. This also allows the case to be more easily visible in low light or dark conditions. In a darkened conference room or meeting hall, this may assist a user in locating the case and also help prevent others from stepping on the case. 
       FIG.  3    shows a top view of various sizes of embodiments of the disclosed hybrid frame sleeve case. In various implementations, the sleeve is sized appropriately for laptops and tablets. For example, the hybrid sleeve may have dimensions appropriate for an Apple MacBook® product (e.g., MacBook Pro® or MacBook Air®) or a similar laptop computer. Sleeves  307  and  309  are shown for a MacBook® product with a 13-inch screen size. The hybrid sleeve may alternatively have dimensions appropriate for an Apple iPad® product (e.g., Apple iPad®, iPad Air®, or iPad Mini®) or a similar tablet computer. Sleeves  314  and  316  are shown for an iPad Air® product. 
     The actual dimensions of the device may vary to accommodate different purposes, including the different sizes and dimensions of electronic devices being housed. 
     In other embodiments, the disclosed case is dimensioned to house a tablet computer, tablet PC, or other tablet-type electronic device. 
     A case protects a portable electronic device enclosed therein from scratches, dings, dents, and other damage. The case also provides shock absorption. The case will absorb impacts, preventing shock to the components of the device. The case may also improve a user&#39;s grip on the device and case combination as compared to the device alone. The case may include a texture pattern, may be made from a tacky material, may have a tacky coating, and/or may include a shoulder, wrist, or neck strap. The case may also be waterproof or water resistant. 
     A texture pattern may be incorporated into the panels or frame, or both, of the case. The texture pattern may be for aesthetics or grip, or a combination thereof. For example, the texture pattern may help hide scratches, scuffs, fingerprints, oil, and other imperfections that may occur to a panel or the frame. For neoprene or other woven or fabric panels, the panel will have a woven texture. For other types of panels or for the frame, the texture can be imprinted or molded into the material. 
     In some embodiments, a mold for the frame includes an inverse or reverse texture, which results in the frame bumper (e.g., exterior side surface of the bumper) becoming molded with the texture. The frame bumper texture may be a pebbled pattern or another pattern, which will appear in relief (e.g., raised) on the frame bumper surface. The frame may be textured using other patterns, such as a waffle pattern or tire thread, which results in the pattern appearing debossed, indented, sunken, or carved into the frame bumper surface. 
       FIG.  4    shows side views for two embodiments of the disclosed case. An empty sleeve  409  is shown for a 13-inch MacBook®. A sleeve  413  containing the product is shown for the 13-inch MacBook®. Sleeve  413  is thicker than sleeve  409  because the product is in the sleeve. 
     The dimensions of the sleeve may be less or about the same as the item to be placed into the enclosed or protective space or compartment of the sleeve. The panels of the sleeve and frame can stretch around the item placed inside the sleeve. Typically the panels stretch more than the frame, and the sleeve holds the item (e.g., laptop or tablet) in place in the sleeve by compression. For example, the two panels are positioned on opposite sides of the device and hold the device so that the frame is positioned against the sides of the device. This ensures the sides of device are protected against side impacts by the frame bumper. 
       FIG.  5    shows side views of a hybrid sleeve  505  and a neoprene sleeve  517  which does not have the EVA frame. Both sleeves are empty. The hybrid sleeve is thinner than the neoprene sleeve without the EVA frame. In this particular example, the reduction in thickness is more than 50 percent. 
     The hybrid sleeve also weighs less than the neoprene sleeve without the EVA frame. As an example, a hybrid sleeve with frame for the Apple MacBook® 13-inch weighs about 195 grams (empty) while the neoprene sleeve without the frame for the Apple MacBook® 13-inch weighs about 272 grams (empty). In this particular example, the reduction in weight is more than 25 percent (e.g., about 28 percent). 
       FIG.  6    shows a close-up view of a tab  603  of a hybrid sleeve. This tab is an extension of the neoprene material and is used to open and close the side opening of the sleeve. 
       FIG.  7    shows an opening  704  of the hybrid sleeve. The EVA frame is covered with a material  708 , which covers magnets. On the neoprene side, there is a bar  712 , which is attached to the neoprene material. Underneath bar  712  are a plastic bar and magnets. The magnets under bar  712  align with those under material  708  to hold the sleeve closed. There is a faux fur lining  715  on the inside of the sleeve. 
       FIG.  8    shows a laptop computer  816  (e.g., MacBook®) positioned inside the sleeve. 
       FIG.  9    shows an overview of the features of an embodiment of the disclosed hybrid frame sleeve case.  FIGS.  10 A- 10 C  show the front, side, and back of the hybrid sleeve. The sleeve has neoprene panels on the front  905  and back  1010 . There may optionally be a screen printed logo (not shown) on the front neoprene panel  905 . For example, the logo may indicate the branding or manufacturer of the sleeve. 
     The sleeve has an EVA protective frame  910  that extends around a perimeter of the sleeve. There is a tab cut out  915  in the EVA frame that is positioned opposite a tab  920  of the front neoprene panel. The tab allows easier opening of the front panel, so a user can access the opening in the sleeve by which the device can be inserted or removed. 
     The opening of the hybrid sleeve is a magnetic opening  925 . Magnets are attached to the neoprene sleeve and the frame. These magnets work in conjunction to hold the opening flap closed. For the magnetic latch, both sides (neoprene and EVA sides) may include magnets for the magnetic latch. Alternatively, only a single side (neoprene or EVA side) may have the magnet, while the other side includes a metal plate (e.g., iron sheet) or other magnetic material to attract the magnet. The magnet will be attracted to the metal plate to keep the opening of the hybrid sleeve closed. 
     In the embodiment of  FIGS.  9  and  10 A- 10 C , the front panel (e.g., with the logo) has an opening for inserting a device into the protective compartment, while the back panel (e.g., without a logo) does not have an opening. In other embodiments, the front panel (e.g., with the logo) does not have an opening while the back panel (e.g., without the logo) has an opening. In some embodiments, both the front and back panels have openings; these openings may be on the same side or different sides (e.g., opposite sides) of the case. 
     Further, the opening in  FIGS.  9  and  10 A- 10 C  is shown as being on the shorter side of the case. In other embodiments, such as shown in  FIGS.  13 - 16 F , the opening is on longer side of the case. In some embodiments, a case may have openings on both the shorter and longer sides, such as a shorter side opening for the front panel and a longer side opening for the back panel. 
     In  FIG.  9   , the inner panels that cover the magnets of the frame (e.g., material  708  in  FIG.  7   ) and inner lining (e.g., lining  715  in  FIG.  7   ) of the sleeve are not shown. 
       FIG.  11    shows an exploded view of an embodiment of the hybrid sleeve having a neoprene front panel  1105  and back panel  1110 . The neoprene panels may have an inside lining, such as a faux fur interior. Other lining materials may be used, such as rubber, foams, or other cushioning materials (see below for listing of materials). The neoprene panels may be laminated to the inside lining. The neoprene panel may also have exterior or interior pockets (not shown) to hold additional items. The case may also include rings, loops, eyes, or other attachment mechanisms (not shown) for a strap such as a shoulder strap. 
     In some embodiments, an EVA protective frame  1115  is positioned between the panels. The frame preferably provides 360 degrees of protection. A recess  1120  along the EVA frame holds the neoprene panels in place for stitching. In some embodiments, the neoprene panels are attached to the EVA frame by stitching. The EVA frame has a tab cut out  1128  that is positioned opposite a tab  1129  on the front neoprene panel. 
     On a side for the opening of the sleeve, the EVA frame includes recesses  1130  for magnets  1135 . There may, for example, be three magnets recesses for three magnets. In some embodiments, a polycarbonate (PC) or neoprene (or other fabric or material such as nylon or polyester) panel  1140  may preferably cover the magnet recesses. This panel may be relatively rigid. There may also be a fabric or other material that is attached (not shown) to the panel covering the magnets. This fabric or material may be a lining material that is glued to the panel to help prevents scuffing or scratching of the portable electronic device by the case. 
       FIGS.  12 A- 12 C  show front, side, and bottom views of the EVA frame. The frame has a recess along the EVA frame to hold the neoprene panels in place for stitching. The frame has recesses for magnets. In these embodiments, there are four recesses for up to four magnets. In various embodiments, there may be any number magnets, such as one, two, three, four, or more. 
     Magnets do not need to be placed in every recess. If desired, three magnets may be used in any three of the four recesses shown in  FIG.  12 A . Then one recess would remain empty. Alternatively, two magnets may be used and placed in any two of the four recesses. 
     Further, the number of recesses and magnets or their sizes or areas, or both, may depend on the sleeve or case design, in particular on the size of the opening. For larger or wider contents (e.g., a notebook as compared to a tablet), the side opening of the sleeve opening will generally be larger. As the opening becomes larger or longer, more magnets may be used for magnetic latching of the opening. For example, more magnets will be typically used for an opening along the longer side edge than an opening on the shorter side edge. 
     In some embodiments, sleeves for tablets (e.g., iPad Air® and iPad Mini®) have a total of six magnets, three for the frame and three for the front neoprene panel. Sleeves for notebook computers (e.g., MacBook®) may have a total of eight magnets, four for the frame and four for the front neoprene panel. The frame in  FIG.  12 A  is an example for a notebook while the frame in  FIG.  11    is an example for a tablet. 
     Referring to  FIG.  12 B , a side (e.g., the shorter side) of the sleeve may optionally include a debossed logo (e.g., a debossed leaf logo) to indicate a branding or manufacturer of the sleeve. The logo may alternatively be omitted. 
     In some embodiments, one or more magnetic latches is used to secure the opening. In other embodiments, other types of latches or fasteners may be used to secure the opening. Some examples of other mechanisms include zippers, hinges, snaps, buttons, hooks, bands, spring latches, cam latches, hook and loop (e.g., Velcro™ by Velcro Industries B.V.), and many others. As an example, one side of the latch (e.g., positioned on the frame) may be a hook (or hook strip) while the other side (e.g., positioned on the panel) may be a loop (or loop strip), or vice versa. 
     Additionally, one or more latches may be along a single side of the case, such as the shorter side of the rectangular case, the longer side of the rectangular case, a combination of a shorter side and a longer side, a combination of longer side and portions of two shorter sides, any three sides, or all four sides, or any combination thereof. 
     Referring to  FIG.  12 A , the structure of frame  1205  (which may be referred to as a frame border) has four sides, a first side, second side, third side, and fourth side. The first side is adjacent to the second and fourth sides, and opposite to the third side. The second side is adjacent to the first and third sides, and opposite to the fourth side. The second side is longer than the first side. These sides of the frame border surround an open space  1223  which forms a compartment into which a portable electronic device may be placed. 
       FIG.  12 D  shows a cross section of the frame along a line  1225 - 1225 . Cross sections of the frame along lines  1227 - 1227  and  1229 - 1229  will be similar to the cross section along line  1225 - 1225 . For example, the cross sections along line  1225 - 1225  and  1229 - 1229  will be mirror images of each other. Line  1225 - 1225  is transverse to line  1227 - 1227 . 
     The cross section of the frame is T-shaped, having a first portion  1234  extending in a first direction  1236  and a second portion  1238  extending in a second direction  1240  that is transverse to the first direction. The first portion has an exterior side  1242  (which may be referred to as a bumper) and an interior side  1244 . The first portion has a first length  1247  from a first end  1249  to a second end  1251  in the first direction. 
     The second portion is connected to the interior side of the first portion at a point  1255  between the first and second ends. The second portion extends in the second direction away from the first portion a second length  1257 . A length  1260  of the entire cross section includes length  1257  and a thickness  1263  of the first portion. This length can be also referred to as a frame border width. 
       FIG.  12 D  also shows panels  1105  and  1110  attached to the frame. In some embodiments, panel  1105  is attached to the frame via stitching  1266  on one side of the frame, and panel  1110  is attached to the frame via stitching  1268  on the other side of the frame. The stitching is positioned along length  1260  of the second portion. As discussed above, panels  1105  and  1110  may alternatively be attached to the frame by other techniques. Typically, the attachment means (e.g., glue or adhesive) will also be positioned along length  1260  of the second portion. 
     A distance  1272  between the second portion and end  1251  of the first portion provides a recess for panel  1105 . As such, after panel  1105  is attached to the frame, a top of panel  1105  (e.g., the exterior surface) will be flush or almost flush with end  1251  of the frame. In some embodiments, the top of the panel is slightly below (e.g., slightly lower) or slightly above (e.g., slight higher) end  1251  of the frame. 
     Similarly, the other side of the frame has a recess for panel  1110 . Panel  1110  is typically the same thickness as panel  1105 . As such, a distance between end  1249  and the portion  1238  will be the same as distance  1272 . However, different panel thicknesses may alternatively be used on the two sides. In such embodiments, the distance between an end of the first portion and the second portion may be adjusted to accommodate the panel thickness to ensure the exterior surface of the panel is approximately flush with the end. The distances between the end and the second portion may be different on different sides. 
     An end  1277  of the second portion has a relatively flat surface, rather than a pointed surface. The device placed inside the case will have its sides abutted or placed against end  1277 . The flat surface (e.g., with its relatively larger surface area) avoids formation of a high pressure point (e.g., a sharper point with relatively less surface area) that could damage the device during impact. 
     Instead of a flat surface, the shape of end  1277  may be designed to match the contours of the device for which the case is designed. For example, if the edge of the device is wedge shaped, the shape of end  1277  will be reverse wedge shaped. If the edge of the device is rounded, the shape of end  1277  will be reverse rounded or concave. 
       FIG.  12 E  shows a cross section of the frame along a line  1279 - 1279 . This cross section is for the frame edge that forms the opening for the sleeve. This cross section is similar to the cross section along line  1225 - 1225  in  FIG.  12 D , but the panel  1105  is not fixedly attached to the frame edge by, for example, stitching or glue. 
     Cross section  1279  has a first portion  1281  and a second portion  1283 . Second portion  1283  is different from second portion  1238  because the frame includes a recessed region  1210  which is for a magnet  1135 . Recessed region  1210  is covered by magnet cover  1140  which holds the magnet in place. 
     In some embodiments, to accommodate the magnet, a length  1285  may be longer than length  1257 . A larger magnet having greater surface area will provide more magnetic attractive force to hold the opening closed, especially during impact. 
     In other embodiments, length  1257  may be the same as or longer than length  1285 . For example, length  1257  may be the same as or longer than length  1285 . This will increase the shock absorption capability of the sides having a longer length  1257 . Further, length  1285  may then be shortened to the same or less than length  1257 . A different latching technology may be used so that magnets are not needed so as to allow for a shorter length. Other embodiments may have any combination of lengthening or shortening of length  1257  or  1285 , or both. 
     In some embodiments, a height  1288  of the first portion along the opening side edge is greater than a height  1247  along a side without the opening. This allows a greater recess length  1290  (as compared to length  1272 ) to accommodate the magnetic latch of panel  1105 . Thus, while panel  1105  is magnetically latched to frame  1205 , the surface of panel  1105  at the opening side will be flush or almost flush with an end of the first portion of the frame. 
     In other embodiments, height  1247  may be the same as or greater than height  1288 . Other embodiments may have any combination of increasing or decreasing of height  1247  or  1288 , or both. A greater height accommodates thicker panel material while maintaining a flush profile between the panel and frame edging. Generally greater higher also allows for greater shock absorption since there is more frame material to dissipate impact energy. 
       FIG.  12 F  shows a cross section of a magnetic latch of a panel along a line  1292 - 1292  (see  FIG.  7   ). A magnet  1294  is attached to panel  1105  to form the magnetic latch. There may also be a magnet holder  1295  to position the magnet on panel  1105 . A magnet cover  1296  covers magnet  1294  and holder  1295  and holds the magnet and holder in place on an interior surface of panel  1105 . The magnet may be attached by stitching or an adhesive. To form the pull tab for the opening, a portion  1298  is made longer. 
     Specific methods and techniques are described for making the disclosed case. However, it should be understood that the disclosure is not limited to the specific methods and steps presented. A method may have additional steps (not necessarily described in this application), different steps which replace some of the steps presented, fewer steps or a subset of the steps presented, or steps in a different order than presented, or any combination thereof. Further, the steps in other embodiments may not be exactly the same as the steps presented and may be modified or altered as appropriate for a particular application or based on the data obtained. Below is an example of a method for making a hybrid frame sleeve case. 
     1. An EVA frame, such as shown in  FIG.  11  or  12 A- 12 C , is formed by an injection molding process or other process used to form polymer materials. The frame has a shape that is the shape of the case. In some embodiments, the frame has a rectangular shape, two longer sides and two shorter sides, and rounded corners. The frame may also be referred to as a gasket bumper or bumper frame. 
     2. A rigid polycarbonate or neoprene (or other fabric or material such as nylon or polyester) panel, a cover for the magnets of the frame, is formed. 
     3. Front and back neoprene panels are formed. These may be cut and formed from a larger sheet of neoprene. The patterns for the front and back neoprene panels may be different, such as where the front panel has a tab while the back panel does not. In other embodiments, the panels may use the same pattern. The front and back panels may also be referred to as front and back panel guards. 
     4. Magnets are placed in recesses of the frame. These magnets are secured in place by the magnet cover. The cover may be attached by glue, epoxy, welding, fusing, lamination, or other techniques for attaching polymers. 
     5. Magnets (or metal sheets) are attached to the front panel. A cover (such a piece  712  in  FIG.  7   ) may be placed over the magnets to hold them in place. These magnets or cover, or both, may be attached by stitching, glue, epoxy, welding, fusing, or other techniques. Typically, the number of magnets for the panel is the same as the number of magnets in the frame. 
     6. A lining material may be attached to the front and back panels. In some embodiments, the lining material is a faux fur. The lining material may alternatively be other materials, including foams, that provide cushioning for the inside of the case. 
     7. The front and back panels are attached to recesses in the frame. These panels are attached to the frame along three sides, leaving one of the shorter sides unattached for an opening of the case. The neoprene panels may be attached by stitching (e.g., using thread that goes through the frame), glue, epoxy, welding, fusing, or other techniques for attaching the panels to the frame. 
     As described, in some embodiments, the frame is made from an ethylene vinyl acetate (EVA). EVA is the copolymer of ethylene and vinyl acetate. The weight percent of vinyl acetate usually varies from 10 to 40 percent, with the remainder being ethylene. EVA is often referred to as expanded rubber or foam rubber. 
     EVA is a polymer that is close to elastomeric materials in terms of softness and flexibility, but may still be processed like other thermoplastics. EVA has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to ultraviolet (UV) radiation. EVA provides cushioning or padding for the sides of the hybrid sleeve. 
     In other embodiments, polymers other than EVA may be used instead of or in combination with EVA. For example, the frame may be made of an elastomer, elastic polymer, elastomeric compound, thermoplastic elastomer (TPE), polyvinyl chloride (PVC), polyurethane, polystyrene, rubber, silicone, or other suitable polymers. An elastomer is a polymer with viscoelasticity (or “elasticity”) and generally has a low Young&#39;s modulus and high failure strain compared with other materials. 
     The frame material may be a foam (e.g., polymer or other substance with trapped bubbles) that provides cushioning or padding. Some examples of foam include quantum foam, polyurethane foam (foam rubber), XPS foam, polystyrene, phenolic foam, or other manufactured foams. Other frame materials may include cork, carbonate, polycarbonate, thermoplastics, thermoplastic polyurethane (TPU), or any combination thereof. The frame materials may alternatively not be a foam or elastic like EVA, but instead have a hard or rigid panel to absorb impacts instead of the contents of the case. The hard panel or surface (e.g., polycarbonate) may crack, shatter, or fracture on impact to distribute the energy of the impact. In some embodiments, the cracked panels can be replaced with replacement panels. Alternatively, the entire case can be replaced after the impact-absorbing panels are spent due to an impact. 
     In some embodiments, the front and back panels are made of neoprene. Neoprene, also known as polychloroprene, is a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene provides cushioning and shock absorption for a portable electronic device protected by the disclosed case. 
     In other embodiments, the outer panels are made from other soft materials, such as fabric (e.g., cotton, wool, linen, polyester, microfiber, or fabric blends), ballistic nylon, woven carbon fiber, thermoplastic elastomer (TPE) material via a mold, other polymers, or other suitable materials, in any combination. The fabrics may include fibers that are woven, nonwoven, or knitted. Other materials may be alternatively used, including silicone, rubber, and many other materials. Other examples of materials include vinyl, polyvinyl chloride (PVC), plastic, thermoplastic, cloth, leather, suede, artificial leather, synthetic leather, synthetic leather made of plastic (sometimes referred to as pleather), poromeric imitation leather, koskin, leatherette, carbon fiber, air mesh, polyurethane (PU), welded polyurethane film, nylon, and polyester, in any combination. 
     In some embodiments, the outer panels are made of nylon or polyester fabric that is environmentally friendly. The fabric may have a dope-dyed fiber, where the color originates from the addition of color chips during the process of polymerization. This avoids the dyeing process, which can causes unnecessary pollution and the release of greenhouse gases. A particular brand of dope-dyed fiber fabric is called Ecoya™ from LIBOLON. In some embodiments, the fabric for the panels may have a heathered pattern. 
     In some embodiments, the materials for the front and back panels are less rigid or more elastic than the frame. The soft panels (e.g., neoprene) may adapt or conform (e.g., stretch) to the surface and shape of the contents being held in the sleeve. The frame is less elastic and has less stretch than the panels. The frame provides a structure for absorbing impacts and protecting the contents of the sleeve. 
     In some embodiments, the frame structure is more shock absorbing than the panel material. To absorb shock, kinetic energy such as that generated during the impact against the case is turned into heat and absorbed by the material instead of transferring the impact energy to the device being protected by the case. This frame structure is more rigid than the panel material, which allows it to absorb more shock. The frame may be a foam. In such embodiments, the trapped bubbles in the foam will act like compressible springs to absorb the shock. After the shock has been absorbed, the frame elastically returns to its original shape (e.g., the bubbles in the foam expand back to their original shape). 
     The panel material may also be a foam, but the spring constant (according to Hooke&#39;s Law) for the compressible springs (bubbles) in the panel material is less than that for the frame. Thus, the panel material will not absorb as much kinetic energy as the frame. 
       FIGS.  13 - 15    show another embodiment of a hybrid sleeve case. This embodiment is similar to the hybrid sleeve case described above. However, instead of having an opening on the shorter side edge of the case, the opening for this embodiment is on the longer side edge of the case. This embodiment has a front panel  1320 , back panel  1325 , longer sides  1330  and  1335 , and shorter sides  1340  and  1345 . Longer side  1330  has a tab  1403  and opening  1504 .  FIG.  15    shows opening  1504  in an open position. A user can pull tab  1403  to open the opening. When closed, tab  1403  is inserted into a tab cut out  1508 . 
       FIGS.  16 A- 16 F  show a frame  1605  for the hybrid sleeve case. This frame is similar to frame  1205  described in  FIGS.  12 A- 12 F  above.  FIG.  16 A  shows a first side of the frame and magnet recesses along a longer edge of the frame rather than along the shorter edge of the frame as in  FIG.  12 A .  FIG.  16 B  shows a longer side edge of the frame where the opening is positioned. A tab cut out  1508  is also shown.  FIGS.  16 C- 16 D  shows the shorter side edge of the frame.  FIG.  16 E  shows a longer side edge of the frame that is opposite to the side edge shown in  FIG.  16 B .  FIG.  16 F  shows a second side of the frame. 
       FIGS.  17 - 24    show an embodiment of the disclosed hybrid frame sleeve case. The case has a front  1720 , back  1725 , sides  1730  and  1735 , and sides  1740  and  1745  that are shorter than sides  1730  and  1735 . Shorter side  1740  has a tab and opening.  FIG.  17    shows a top view of the front side.  FIG.  18    shows side  1730 .  FIG.  19    shows a perspective view of the front with side  1740  positioned forward.  FIG.  20    shows a perspective view of the back with side  1735  positioned forward and with tab  2003 .  FIG.  21    shows a perspective view of the front with side  1730  positioned forward.  FIG.  22    shows a perspective view of the back with side  1730  positioned forward and with tab  2003 .  FIG.  23    shows a perspective view of the back with the opening  2304  lifted open and a tab cutout  2308 . 
       FIG.  24    shows an EVA protective frame  2405  for the hybrid sleeve case. Sides  1730 ,  1735 ,  1740 , and  1745  of the hybrid case are formed by the EVA frame. As discussed above, such as for  FIG.  12 A , the frame has recesses  1210  for magnets. Additionally, EVA frame  2405  has reinforced corners  2408 , where an additional layer is added to the EVA at the corner, or the EVA layer is created to have a thicker portion. The additional layer may be EVA or other materials that have been previously discussed for the EVA frame. The reinforced corners of this hybrid are visible in  FIGS.  17 - 23   . The reinforced corner may be referred to as a bumper or corner bumper. The corner bumpers may provide additional protection and cushioning for the corners of the case. 
     In some embodiments, corner bumpers are part of the mold for the EVA frame. In other embodiments, corner bumpers are attached to the EVA frame. The corner bumpers may be attached to the frame, for example, by gluing, fusing, or other methods. 
     In some embodiments, the corner bumpers are made of EVA. In other embodiments, the corner bumpers may also be made of PU, rubber, or other materials. The corner bumper may be made of the same material as the EVA frame. Alternatively, the corner bumper is made of a different material than the EVA frame. 
     While four corner bumpers are shown, there may be more or fewer bumpers. For example, each corner may have two corner bumpers. However, each corner does not have to have the same sized bumpers, the same number of bumpers, or use the same material for the bumpers. 
     In these embodiments, the front and back panels for frame  2405  have raised rails  1765 . Like the corner bumpers, the raised rails  1765  may provide additional protection and cushioning for the case. 
     In some embodiments, the raised rails are attached to only the front panel of the case. In other embodiments, the raised rails are attached to only the back panel of the case. In other embodiments, the raised rails are attached to both front and back panels of the case. 
     The raised rails shown are rectangular prisms that approximately span the shorter side of the case. In other embodiments, the raised rails may be different shapes, such as cylinders and triangles. The raised rails may also be oriented such that they are attached like legs of a table. 
       FIG.  25    shows a cross section of rails of a panel of an embodiment of the disclosed hybrid sleeve case. A rail structure layer  2504  is positioned between an exterior layer  2506  and interior layer  2508 . The rail structure layer provides the rail structure. In some embodiments, the layers are laminated together. In other embodiments, the three layers are attached together by an adhesive. The rail structure may be made from a polymer material such as EVA and the exterior and interior layers may be made from fabric, such as nylon or polyester, or a material such as neoprene. 
       FIGS.  26 - 43    illustrate an embodiment of the disclosed hybrid frame sleeve case  3000  for a portable electronic device  4000 , such as a laptop computer or tablet, where the case includes a charging system. The particular sleeve case illustrated in the drawings is configured for a Macbook Pro®, such as the one shown in  FIG.  42 G . The case  3000  is capable of allowing the user to charge the portable electronic device, with or without a wire, whether the device is inside or outside the case. In addition, the case is capable of charging other devices connected to the electrical interface connectors, which also allows the sleeve case to be charged through outside power sources. 
     In the illustrated embodiment, the case  3000  is rectangular in shape with rounded corners and includes front face, back face, left, right, top and bottom sides  3010 ,  3020 ,  3020 ,  3030 ,  3040 ,  3050 , and  3060  respectively. The shape of the case  3000 , and particularly the device compartment  3600 , generally corresponds to the external shape of the portable electronic device for which the case is configured, which for laptop computers would be determined when the laptop is in the fully closed position such that the screen is closed over the keyboard. 
     The case  3000  is comprised of a frame structure  3100 , a front face panel  3200 , and a back face panel  3300 . The back face panel  3300  houses a rechargeable battery  3325 , which is connected to external and internal electrical interfaces  3421 ,  3422 ,  3431 , and  3432 , respectively, via a printed circuit board (PCB)  3410  that facilitates and controls the charging operations of the rechargeable battery  3325  of the case. The PCB  3410  is secured to the case via a rigid mounting support  3500  that is attached to the back face panel  3300  via mechanical fasteners (e.g., screws, rivets, or the like) and/or adhesive or other suitable methods of attachment. An LED battery charge gauge  3440  is also electrically connected to the PCB and mounted to the case so as to be externally visible to the user. A user activation button  3445  is provided and electrically connected to the PCB and mounted to the case to allow the user to externally engage and activate the charging operations of the case. 
     The front and back face panels  3100  and  3200  are attached to the frame structure  3100  on opposing sides thereto via stitching  3900  and/or other suitable techniques (e.g., glue, epoxy, welding, and/or fusing). When assembled, the front face panel  3200  and the perimeter region of the back face panel  3300  are flush or almost flush with the adjacent region of the exterior edge surface  3001  of the frame structure  3100  so as to provide an integrated and seamless appearance and construction. It should be understood, however, that in some embodiments the front and/or back face panel may be slightly below (e.g., slightly lower) or slightly above (e.g., slight higher) the adjacent regions of the exterior edge  3001  of frame structure  3100 . 
     To provide access to the case, the front face panel  3200  includes an access flap  3201  (best illustrated in  FIG.  42 B ) that bends along a fold line and allows the user to open the sleeve and slide the portable electronic device into and out of the sleeve compartment  3600 . To bias or otherwise keep the access flap  3201  in the closed position, magnetic elements or material (e.g., iron sheet) is incorporated into or otherwise attached to the flap  3201 . The magnetic elements or material in the access flap  3201  are positioned so that they overlie the magnets  3800  when the flap is in the closed position so that the magnetic attraction there-between keeps the flap closed. Opening the access flap  3201  also allows the user to also access a connector cable  3700  that may be employed to connect a portable electronic device to the rechargeable battery  3325  to facilitate charging of the device as, for example, illustrated in  FIG.  42 G . 
     The front face panel  3200  and frame structure  3100  may be formed of any suitable material and construction, as described above. In the illustrated embodiments, the front face panel  3200  is comprised of a multilayered flexible construct that includes a cushion core (such as neoprene or polychloroprene, synthetic rubber, or other cushioning material) overlaid by synthetic or natural fabric on its inner and outer surfaces. The fabric may be laminated or otherwise adhesively attached or adhered to the cushioning core. The fabric laminated on the outside surface of the cushion core layer may be different than the fabric laminated on the inside surface of the cushion core, which may be softer and less abrasive (e.g., a faux fur lining) to protect the outer surfaces of the portable device. Once the multilayered construct of the front face panel  3200  is formed, the construct is cut to size and attached to the frame structure  3100 , by stitching or other techniques as previously described. 
     The frame structure  3100  (best illustrated in  FIGS.  34 ,  37 ,  38 ,  39  and  40   ) is comprised of a frame border having an exterior edge  3101  and interior edge  3102 . The exterior and interior edges are separated by the width  3003  of the frame border. The interior edge surrounds a perimeter of a device compartment  3600 . As best illustrated in  FIG.  39   , the frame structure  3000  has a generally T-shaped cross section and includes a first portion  3104  extending in a first direction  3105  and a second portion  3106  extending in a second direction  3007  that is transverse to the first direction. The first portion  3104  comprises the exterior edge  3101  and the second portion  3106  comprises the interior edge  3102 . The first portion  3104  has a first length  3108  from a first end  3109  (which is located at the back face side  3020 ) to a second end  3110  (which is located at the front face side  3010 ) in the first direction  3105 . The second portion  3106  has a second length  3112  from a third end  3113  to a fourth end  3114  (which is located at the interior edge  3102 ) in a second direction  3107 . The second portion  3106  is coupled to the first portion  3104  at a point  3115  between the first and second ends  3109  and  3110  and extends in the second direction  3107  away from the first portion  3104  a second length  3112 . 
     As best illustrated in  FIGS.  34 ,  37 - 38 , and  40   , the configuration and lengths  3108  and  3112  of the first and second portions  3104  and  3106  respectively vary depending on the location where the cross section is taken. In the illustrated embodiment, the left and right sides  3030  and  3040  of the frame structure  3100  are symmetrical and have a uniform cross-section such as that depicted in  FIG.  39   . The frame structure  3000  at the top end  3050  of the case  3000  has, by contrast, a second portion  3106  that has a substantially longer length  3112  than the second portion  3106  located at the sides  3030  and  3040  of the case  3000  and includes therein internal compartments  3120  for housing magnets  3800  and an internal compartment  3130  that is configured to retentively secure and house the cable  3700  therein. In addition, the second portion  3106  of the frame structure  3100  that resides at the top side  3050  of the case  3000  includes a recessed region  3140  that is configured to receive and be covered, in a flush configuration, by a magnet cover  3850  which assists in maintaining the magnets  3800  in place with their compartments  3120 . The magnet cover  3850  may be attached by glue, epoxy, welding, fusing, lamination, or other techniques for attaching polymers. 
     In some embodiments, the frame structure is formed of injected molded ethylene vinyl acetate (EVA) as a unitary component as described above. Other suitable materials may also be used. The material that forms the cushion core of the front face panel  3200  may be the same or different than the material that forms the frame structure  3100 . In some embodiments, the cushion core of the front face panel  3200  is formed of a neoprene sheet and the frame structure  3100  is formed of injected molded ethylene vinyl acetate (EVA). 
     As best illustrated in  FIGS.  35  and  36   , the back face panel  3300  is comprised of an internal panel  3310  and an outer panel  3320 . The outer panel  3320  defines a battery compartment  3321  that houses a rechargeable battery  3325 . The outer panel  3320  includes a flat perimeter region  3329  that is configured to mate with the perimeter surface of the internal panel  3310 . A rigid battery tray  3327  is included to further protect and support the rechargeable battery  3325 . The outer panel  3320  may be formed of any suitable material. In some embodiments, the outer panel  3320  is formed of a multilayered construct comprising a compression molded EVA sheet core that is laminated on its outer surface with a fabric, the same fabric as that laminated on the outer surface of the front face panel  3200 . Once the multilayered construct is formed, the multilayered construct is molded into shape to define the battery compartment  3321  and cut to size for assembly to the other components. The internal panel  3310  may be formed of a soft or flexible material to serve as a cushion between the rechargeable battery  3325  and the electronic device contained in the device compartment  3600 . In some embodiments, the internal panel  3310  has the same material as that of the front face side panel  3200 . Alternatively, the internal panel  3310  may be formed of other suitable materials such as a thin sheet of rigid plastic or other polymer. The surface of the internal panel  3310  that faces the device compartment  3600  may be lined with a suitable fabric such as faux fur to protect the device. 
     The rechargeable battery  3325  may be comprised of one or more rechargeable batteries or battery banks connected to a PCB  3410 . The PCB  3410  is connected to the rechargeable battery  3325  via connection  3326  (illustrated in the block diagram of  FIG.  41   ) and controls the charging and discharging of the rechargeable battery  3325 . Electrical interfaces  3421 ,  3422 ,  3431 , and  3432  are mounted to the PCB. These electrical interfaces may be any suitable standard or proprietary connector such as a USB connector, a contact connector, an Apple Lightning connector, and/or a magnetically retained connector. 
     The external electrical interfaces  3421  and  3422 , in some embodiments, may be USB type A and USB type C female connectors, respectively, that are adapted to allow for charging into and out from the rechargeable battery  3325 . The internal electrical interfaces  3431  and  3432  are selected and positioned to enable connection with the electrical interface or connector on the portable electronic device when the device is inserted into the case. Thus for example, if the portable electronic device includes a USB type C female connector on one of its sides, the internal electrical interfaces  3431  and/or  3432  would be mating USB type C connectors and positioned to operationally align into connection with the device connector when the device is inserted into the case. Similarly, if for example the portable electronic device includes an Apple Smart connector, then the internal electrical interfaces  3431  and/or  3432  would be of the same type and positioned internally within the sleeve compartment to operationally align with the Apple Smart connector on the device when the device is inserted into the case. Magnetically retained connectors, such as the Apple MagSafe connector and those described in U.S. Pat. No. 7,658,613, which is hereby incorporated by reference in its entirety, may also be used as internal electrical interfaces  3431  and/or  3432  to facilitate alignment and connection to the device. In some embodiments, an electrical adaptor is provided that connects to the portable electronic device connector on one side and provides a magnetic or contact connection on the other side which is adapted to interface with the internal electrical interfaces positioned within the sleeve compartment. 
     The positioning of the internal electrical connectors  3431  and  3432  is determined to correspond with the position of the corresponding electrical connectors on the device. Positioning the internal electrical connectors  3431  and  3432  in the sleeve so that one of the internal electrical connectors is in operational alignment with a corresponding device connector when the device is inserted into the sleeve in a first orientation and a second internal electrical connecter is in operational alignment with a corresponding device connector when the device is inserted in the sleeve in a second orientation allows the case to charge the device when the device is inserted in the sleeve from different sides or upside down. For devices that have multiple charging ports or connectors, a plurality of internal electrical connectors positioned in the sleeve compartment allows the case to charge the device through one or more device connectors simultaneously or in the alternative. 
     In some embodiments, one or more wireless (or inductive) charging components  3350  may be included in the battery compartment  3321 , or other locations in the power sleeve case  3000 , as best shown in  FIG.  43   . The wireless charging components  3350  may include one or more wireless charging receivers and or wireless charging transmitters. The wireless charging components  3350  may be configured to charge one or more wireless charging enabled devices (e.g., phone, tablet, smart watch, etc.) housed in or adjacent to the power sleeve case  3000 . In this configuration, the wireless charging components  3350  include an inductive transmitter that is adapted to wirelessly charge a correspondingly enabled device in sufficient proximity to the transmitter (e.g., housed inside or on top of the power sleeve case  3000 ) by transmitting power from the rechargeable battery  3325  and wirelessly transferring that energy to a wireless receiver of the wireless charging enabled device to thereby power the device and/or recharge the battery of the wireless charging enabled device. 
     In other embodiments, the wireless charging components  3350  may be configured to include an inductive wireless receiver that is capable of receiving charge from an external corresponding wireless transmitter and transmitting that charge to the rechargeable battery  3325  positioned in the power sleeve case  3000 , thereby recharging the battery  3325  wirelessly. Hence, power from an external power source can be transferred to the rechargeable battery  3325  through the wireless charging component  3350 . 
     Further, it should be understood that the wireless charging components  3350  may include both inductive receiver and transmitters to facilitating recharging of the rechargeable battery  3325  and wireless charging of wireless charging enabled devices as described above. The wireless charging components  3350  may be compatible with one or more wireless charging standards (for example, Qi, PMA, AirFuel Alliance standards, etc.). 
     As best illustrated in  FIG.  40   , with reference to the drawings illustrating the fully or partially assembled case  3000 , the rigid mounting support  3500  secures the electrical components  3410 ,  3421 ,  3422 ,  3431 ,  3432 ,  3440 , and  3445  to the back face panel  3310  via an opening  3323  in the outer panel  3320 , a corresponding opening  3311  in the internal panel  3310 , and a corresponding control panel cut out  3151  in the bottom side of the frame structure  3100 . Hence those electrical components are housed within the back panel  3300  and the frame structure  3100 , which surrounds and provides protection and support to the internal and external electrical interfaces  3421 ,  3422 ,  3431 ,  3432 , the PCB  3410 , and the other components thereon.
