     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to docking connectors for mobile electronic devices. In particular, embodiments of the present invention relate to docking connectors disposed on a largest-surface-area surface of the electronic devices. 
         [0004]    2. Discussion of Related Art 
         [0005]    Mobile electronic devices often comprise docking connectors, which enable the mobile electronic devices to temporarily attach to multiple external docking accessories, such as speakers and batteries, generally further enabling power and data transmission between the mobile electronic device and the docking accessories. Docking connectors are generally housed on one of the edges of the mobile electronic device, as opposed to one of the two major faces of a typical mobile electronic device, wherein the front face is generally designated by the location of a screen, should the device house a screen, and the back face is designated as the face opposite the front face. For example, the smartphone shown in  FIG. 1A  (Prior Art) has two major faces and four relatively narrow edges, with a docking connector housed on the bottom edge. A shortfall of housing a docking connector on the edge of a mobile electronic device is that when the device is attached to docking accessories, the resultant system is generally inconvenient for transport. If the docking accessories attach by a flexible cable to the docking connector as shown in  FIG. 1A , the resultant system comprises two or more independently moving bodies, connected by the flexible cable, and is thus inconvenient for transport. If the docking accessories attach in a rigid fashion to the docking connector, the resultant system generally increases the effective magnitude of at least one of the dimensions of the mobile electronic device to a degree that renders the resultant system inconvenient for transport. This is due to the fact that the edges of mobile electronic devices generally have a relatively small surface area compared to the front and back faces of the devices; thus, to accommodate the volume of a docking accessory that is rigidly attached to such an edge, the resultant system generally extends significantly in directions away from the docking connector edge. See for example  FIG. 1B  (Prior Art). 
         [0006]    To address the preceding docking-system transport problem, some docking accessories, such as certain supplemental batteries, are manufactured as parts of mobile electronic device cases. The resultant “docking cases” attach to mobile electronic devices, both at their docking connectors (as standard docking accessories attach) and around their various edges (as standard mobile electronic device cases attach), to enable the docking accessories to be transported securely against the back faces of the mobile electronic devices. See for example  FIG. 1C  (Prior Art). In a similar vein, some docking accessories are manufactured as parts of docking “sleeves” (or “jackets”), which attach to compatible mobile electronic devices at their side edges and at their docking connectors (some docking sleeves are themselves operable to form detachable attachments to independent docking accessories). See for example  FIG. 1D  (Prior Art). Docking cases and sleeves enable the majority of the volume of docking accessories to be distributed in a generally even manner across the relatively large back faces of mobile electronic devices, with the aim of minimizing effective increases in magnitude to any single dimension of the mobile electronic device and thus enabling the resultant systems to be transported in a convenient fashion. While going some way to mitigate the increase in effective size of mobile electronic devices to which docking cases and sleeves are attached, the main shortfall with this method for addressing the docking-system transport problem is that docking cases and sleeves nevertheless can increase the effective size of the corresponding mobile electronic device, both in the dimension perpendicular to the back face of the mobile electronic device and in the dimension perpendicular to the face of the edge that houses the docking connector. 
         [0007]    A second method for addressing the docking-system transport problem is to (i) recess a portion of a selected edge of a mobile electronic device to form a rectangular cavity that is open both at the selected edge and at the backside of the mobile electronic device; (ii) form a docking connector on the recessed edge; and (iii) form rails (or tracks) on the two cavity edges perpendicular to the recessed edge. See for example  FIG. 1E  (Prior Art). The rails serve to guide docking accessories as they are inserted into the rectangular cavity through the opening on the selected edge and to help fix the positions of the docking accessories when they are in their docked states. The rectangular cavity enables docking accessories to attach to the mobile electronic device without increasing its effective carrying size. For certain designs, the initial formation of the cavity may lead to an increase in the initial carrying size of the mobile device by taking up space that could otherwise be used for internal components of the device; still, the cavity enables docking accessories to attach to the device without further increasing its effective carrying size and without altering its overall contour. This method thus avoids the main shortfall with the preceding method. Nevertheless, it has several shortfalls of its own. One shortfall with this method is that its rail system requires the corresponding accessory cavity to be open at one edge of the mobile device. This is disadvantageous, as edge openings reduce available space for mobile-device features that are ideally located on an edge of the device (for instance, volume buttons, power buttons, built-in speakers, and built-in sensors) and, if the selected edge is tapered, as is common to create the perception that the device is only as thick as its outermost edges, the tapered boundary of the corresponding accessory cavity places adverse constraints on the design of compatible docking accessories. Another shortfall with this method is that, by fixing the positions of the outer edges of attached accessories through its rail system, it presents design obstacles for a broad range of accessories whose functionality improves with the ability to expand away from, and rotate at various angles to, the backsides of the mobile electronic devices to which they are attached (for instance, speakers, electrophysiology sensors, massage paddles, hand-pump chargers, and ultrasound transducers). Another shortfall with this method is that accessories whose attachment does not increase the effective carrying size of the mobile device must have a certain rectangular shape and size to mate with the rail system (and those accessories that protrude beyond the boundaries of the rectangular cavity must have a base of a certain rectangular shape and size to mate with the rail system). Different docking accessories have different ideal shapes and sizes, however. For instance, whereas certain camera lenses, speakers, and electrophysiology sensors might ideally be circular and relatively small, certain game controllers, external keyboards, and solar panels might ideally be elongated and relatively large. 
         [0008]    What is needed is a docking platform that is housed on the back face of a mobile electronic device to enable multiple docking accessories of various shapes and sizes to simultaneously and independently attach to the mobile electronic device with the optional freedom to expand away from, and rotate at various angles to, the back face of the mobile device, and with at most a nominal increase to the effective magnitude of any one dimension of the mobile device. Furthermore, the docking platform should not require openings on the edges of the mobile device. 
       SUMMARY OF THE INVENTION 
     Cavity-Recessed Accessory Embodiments 
       [0009]    Some embodiments of the present invention, as shown herein, are directed to mobile electronic devices having docking connectors. One of these embodiments of the device includes a docking platform formed at one of the largest-surface-area surfaces, i.e., a selected surface, of the mobile electronic device. In the present embodiment, the selected surface is the back surface of the device. In a separate embodiment, the selected surface may be the front, screen supporting surface. The docking platform is formed with a docking connection system which includes one or more docking connectors generally disposed in a recessed docking accessory cavity. The docking connection system is configured to enable the recessed docking accessory cavity to be open only at the selected surface. 
         [0010]    In some embodiments, the recessed docking accessory cavity enables one or more docking accessories to be attached to the docking connectors without significantly increasing the effective carrying size of the mobile electronic device. Docking accessories are manufactured to couple with the recessed docking accessory cavity such that, when the docking accessory is in at least one mode of operation, the outer surface of the docking accessory is generally co-planar with the selected surface of the mobile device. 
         [0011]    In one embodiment, the docking connection system is formed to accommodate a broad range of docking accessories. In the same or separate embodiment, the docking connection system is operable to form a detachable attachment to multiple independent docking accessories simultaneously. In the same or separate embodiment, the docking connection system is operable to form a detachable attachment to one docking accessory via two or more recessed docking accessory cavities. In the same or separate embodiment, the docking connection system may be operable to form a detachable attachment radially inward from the outer edges of a circular accessory, to allow the body of the accessory to temporarily expand away from the docking platform by way of an expandable conical accordion mechanism, whereby the foot, or narrowest part of the accordion, which is located radially inward from the edges of the accordion, forms the attachment point to the docking connection system, and the mouth, or widest part of the accordion, forms an attachment to the body of the accessory. The range of docking accessories that may cooperate with the docking platform includes, by way of example, batteries, solar panels, game controls, LED lights, hand-crank chargers, weather sensors, camera flashes, camera lenses, electrophysiology sensors, memory cards, keyboards, massage paddles, glucose monitors, body fat monitors, breathalyzers, ultrasound transducers, and pulse oximeters. This list of possible docking accessories in not meant to be limiting in any way, but is merely meant to demonstrate the wide range of possible devices and technologies that may functionally cooperate with the present docking platform. 
         [0012]    In one or more embodiments, the docking platform is integrally formed with the body of the mobile electronic device. In a related embodiment, the docking platform is integrally formed with one aspect of the mobile electronic device, e.g., the back cover. The docking platform may be formed with an accessory cavity that has a generally oval shape. In one embodiment, the generally oval or capsule shaped accessory cavity (herein after, “oval shaped accessory cavity”) supports two circular cavities formed at opposing ends of the oval shaped accessory cavity. Optionally, a depressed region constituting the middle portion of the oval cavity may be formed between the two circular cavities. Each of the two circular cavities may include a docking connector, for example, an annular docking connector disposed at its center. A docking connector may be formed with a connection mechanism, electrical contacts for communication one or both of data and power, and an optional alignment mechanism. For example, in the annular docking connector embodiment, each docking connector may be formed with (i) an annular female snap-fit feature, for attaching docking accessories securely to the docking platform; (ii) 30 electrical contacts disposed evenly around the inner edge of the female snap-fit feature, for transmission of power and data to and from docking accessories; and (iii) a male index key, to ensure that the electrical contacts on a docked accessory mate with the appropriate contacts on the docking connectors. The electrical contacts are formed of gold-plated nickel-plated copper, with copper pads, and the remainder of the platform is formed of the same hard material as the rest of the body of the mobile electronic device. Other connection mechanisms, electrical contacts for communication one or both of data and power, and alignment mechanism may be used without departing from the scope herein. 
         [0013]    One skilled in the art will appreciate other possible embodiments, which vary in (i) shape of platform; (ii) size of platform; (iii) number of docking accessory cavities; (iv) shape of docking accessory cavities; (v) size of docking accessory cavities; (vi) number of docking connectors; (vii) shape of docking connectors; (viii) size of docking connectors; (ix) mode of attachment of docking connectors to docking accessories; (x) configuration of electrical contacts; (xi) number of electrical contacts (including zero); (xii) mode of attachment of platform to the body of the mobile electronic device; and (xiii) materials of the platform and its components.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0149]    One advantage of the present invention is that it allows multiple docking accessories to attach simultaneously and independently to the mobile electronic device. Some docking accessories, such as supplemental camera lenses and flashes, stereo speakers, and electrophysiology sensors, naturally work together in pairs. As such the present invention fulfills the need for a method that enables multiple docking accessories to attach simultaneously to the mobile electronic device. Furthermore, different circumstances might call for one and the same accessory to be paired with different partner accessories. For instance, a daytime circumstance might call for a supplemental camera lens accessory to be combined with a supplemental battery accessory, whereas a nighttime circumstance might call for the same camera lens to be combined instead with a supplemental flash accessory. The present invention fulfills the need for a method that enables multiple docking accessories to attach both simultaneously and independently to the mobile electronic device. 
         [0150]      FIGS. 2A-C  illustrate one embodiment of docking connectors  4 .  FIGS. 3A and 3B  illustrate one possible alternative embodiment of docking connectors  5 . In both embodiments a plurality of electrical contacts  19  are arranged in a circular pattern about the docking connectors. It will be appreciated that other patterns, shapes, and numbers of connectors may be used without departing from the scope herein. By way of example, pins of a docking connector are arranged as shown in Table 1. The same contacts could be arranged in various circular patterns to form, for example, the connector patterns as shown in  FIGS. 2A-C  and  FIG. 3A-B . Depending on the specific docking connector configuration of the mobile electronic device and what accessory is to be used, various pins are connected and active.

         [0229]      FIG. 35  shows a flowchart  210  illustrating an embodiment of a software and logical interface method between docking platform  2 ,  102  or mobile electronic device  1 ,  101 , and compatible docking accessories. At step  200 , method  210  determines if a wired and/or wireless docking accessory is physically docked to a compatible docking platform, such as docking platform  2 ,  102 ,  102 A-E. If a docking accessory is physically docked, method  210  moves to step  201 , otherwise method  210  moves to step  202 . 
         [0230]    At step  201 , method  210  determines if the docking accessory is electrically connected to an electrical contact-compatible docking platform. In one example, docking platform  2 ,  102  or mobile electronic device  1 ,  101  determines that camera accessory  142  is electrically connected. If method  210  determines that there is no electrical contact made, method  210  moves to step  202 . 
         [0231]    At step  202 , method  210  determines if the docking accessory is a docking accessory that supports one or more of wireless communication and wireless power transfer. In one example, docking platform  2 ,  102  or mobile electronic device  1 ,  101  determines that camera accessory  142  is a wireless camera accessory. If in step  202 , method  210  determines the docking accessory is not a wireless accessory, method  210  moves to step  204 , where no data or power link is formed and no further action is taken. If in step  202 , method  210  determines that the docking accessory is a wireless docking accessory, step  202  moves to step  203 . 
         [0232]    At step  203 , method  210  attempts to establish an authenticated communication link with the docking accessory. If no link can be established, method  210  moves to step  204 , and no further action takes place, otherwise, once linked, method  210  moves to step  205 . 
         [0233]    At step  205 , method  210 , a determination is made regarding the type and configuration of the linked docking accessory. In one example, docking platform  2 ,  102  or mobile electronic device  1 ,  101  determines that a docking accessory is one type of camera accessory  142 , wherein the lens of camera accessory  142  is a 28 mm F/1.8 lens that does not include an integrated flash. The type and configuration of the linked docking accessory, in one embodiment, is determined by message passing between the docking accessory and mobile electronic device  1 . Method  205  then moves to step  206 . 
         [0234]    At step  206 , method  210  determines, for example by using additional message passing, the types and level of cooperation/operability supported by docking platform  2 ,  102  or mobile electronic device  1 ,  101  and one or more docking accessories. In one example, docking platform  2 ,  102  or mobile electronic device  1 ,  101  determines that a docking accessory supports one or more interoperability modes, for example a camera accessory  142  that interoperates with a flash accessory  143 . In another example, docking platform  2 ,  102  or mobile electronic device  1 ,  101  determines that a docked speaker accessory  148  can interoperate with another docked speaker accessory  148  to form a left and right stereo speaker pair or a bass and treble speaker pair. In still another example, docking platform  2 ,  102  or mobile electronic device  1 ,  101  determines the docking accessory is a single docking accessory that utilizes two or more docking connectors, like game controller accessory  158 , battery accessory  146 , or solar charger accessory  147 . Method  210  then moves to step  207 . 
         [0235]    At step  207 , method  210  performs one or more functions, dependent on the number, type, configuration, and operability mode(s) of one or more currently docked docking accessories. As an example, docking platform  2 ,  102  or mobile electronic device  1 ,  101  may include provision to enable speaker accessories  148  to cooperate to receive left and right channel amplified signals so as to function as a stereo speaker system, as depicted in  FIG. 33 . In another example, docking platform  2 ,  102  or mobile electronic device  1 ,  101  may include provision to enable camera accessory  142  and flash accessory  143  to coordinate such that a flash is delivered under low light conditions when an image capture event is signaled, as depicted in  FIG. 32 . In still another example, a wireless link is established at step  203 , and a wireless scale may operate, in one embodiment, independently of any docked accessories.
