Description:
FIELD OF THE INVENTION 
     The present invention relates to the field of peripheral devices for use with computer hardware. 
     BACKGROUND 
     Computer peripheral devices (“peripherals”) are hardware that extend the capabilities of a computer system without permanently altering its architecture. Peripherals include devices that accept output from the computer, communicate input, and both. 
     Recently, peripherals have emerged that are specialized for use with small, portable computers, such as smartphones, tablets, and other personal digital assistants (collectively, “PDAs”). Some of these devices interact with the PDA through dedicated input/output connectors, such as USB ports, or other data communications ports. However, because many of such ports are various and often proprietary, and peripherals often need to be compatible with a variety of PDAs, peripheral manufacturers are increasingly turning to use of the uniform analog 3.5 millimeter telephone jack (“phone jack”), through which many PDAs can accept, as well as transmit, data. For example, the company Square, Inc. has developed a magnetic strip reader that uses the phone jack to process electronic transactions through a variety of PDAs. Other companies have developed a variety of peripherals including additional and different sensors than the PDA alone, using the phone jack. 
     As another alternative to hard-wired connections, some peripherals utilize local wireless networks to establish communications with a PDA. These may be termed personal area networks (“PAN”), although some definitions of personal area networks may include hard-wired networks. Wireless personal area networks (“PAN”) have been in use at least since the advent of BlueTooth, in 1994, created by Ericsson. 
     It should be understood that the disclosures in this application related to the background of the invention, in, but not limited to this section titled “Background,” do not necessarily set forth prior art or other known aspects exclusively, and may instead include art that was invented concurrently or after the present invention and conception, and details of the inventor&#39;s own discoveries and work and work results. 
     SUMMARY OF THE INVENTION 
     New techniques for establishing communications connections for computer peripheral devices are provided. In some aspects, new forms of Audio-Jack-connecting peripheral devices are disclosed, which permit the continued access to the phone jack of a PDA for purposes other than communication with the peripheral device—such as, for communication with other peripheral devices—while using the Audio Jack as a gripping piece for physical mounting. In some embodiments, a void within a connecting pin or strip permits direct access to at least a part of the PDA&#39;s Audio Jack, minimizing the footprint of the peripheral device, along with additional beveling, shaping and flush-mounting. 
     In other aspects, a new technique for rapidly establishing a uniform, secure wireless peripheral device network for such a peripheral device is provided, permitting it to reduce its profile even further by omitting the mounting pin or strip and, instead, gripping another part of the PDA housing, such as the front with a small overhang. 
     In some embodiments of the invention, the secure peripheral device network is activated by physical docking and/or interlocking, without any use of a wired network connection, based on precise proximity and location information. In other embodiments, a secure, encrypted peripheral device network is established by a system in response to terminating a wired network connection, easing the transition from wired to wireless connection status, and easing the creation of a wireless network, generally.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  is a side view of an exemplary peripheral device system  101  which may access the Audio Jack of a PDA, but which also provides external, additional access to the Audio Jack of the PDA, in accordance with aspects of the present invention. Among other advantages, device  101  maintains a low additional profile when installed onto a PDA, abutting the housing of the PDA on two sides: vertical inward-facing side  103  and horizontal inward-facing side  105 . When device  101  is properly installed on a PDA, each of sides  103  and  105  is preferably pressed at least partially flush against the outer housing of the PDA, and device  101  adds a relatively small additional width over a broad area of the PDA&#39;s outer housing, in most circumstances, next to those flush regions of contact. In other words, device  101  maintains a low profile against the housing of a PDA onto which it is installed. That low additional profile is highlighted in the present, side view, where device  101  is at its thinnest. For example, the width of a main body  104  of device  101  (from the side view, pictured) is preferably no more than ½ of the PDA&#39;s width from a side perspective, and, even more preferably, is no more than ⅓ or ¼ of the PDA&#39;s width. Also preferably, main body  104  is substantially thinner than both the vertical and horizontal width of the remaining sections of the device, by at least the same proportions, and, preferably, an even more differential ratio (although not pictured). 
     To install device  101 , a user may insert interfacing strip or pin  107  into an Audio Jack of a PDA, until device  101  snaps into place, with strip/pin  107  fully inserted into the Audio Jack. Strip/pin  107  preferably guides the installation of device  101  as it inserts into, and interlocks with, an Audio Jack, maintaining the installed state of device  101  until a user disengages it from a PDA. Strip/pin  107  also preferably maintains functional electronic communication between device  101  and the Audio Jack, allowing device  101  and the PDA to maintain input and output communications. However, strip/pin  107  also preferably maintains a hollow void within itself and, preferably, in at least part of the Audio Jack, and, in any event, permits the at least partial insertion of, and enabling communications for the PDA and/or device  101  with, a phone plug (for example, allowing communication with a separate audio device, such as a set of headphones, or other device) though its own auxiliary Audio Jack  108 . Different preferred forms for a strip/pin such as  107  are discussed in greater detail below, in reference to  FIGS. 7-9 . 
     Device  101  includes a main body  104  that may house or otherwise at least partially comprise a variety of different peripheral device components, to extend the capability of the PDA by electrically connecting them to the PDA through the Audio Jack, or otherwise as discussed in this application. Some such device components may be actively powered by the PDA, for example, also through the Audio Jack, or through transmitted, ambient power, while other such device components may have their own, local power source, which may also be within the main body  104 . For example, main body  104  may house an external modem, sensor, display, other actuator, or sets of such components, and connect them to the PDA allowing them to communicate with the PDA, and vice versa. In some variations, the device  101  may be capable of carrying out functions both while connected to the PDA, and when detached, and may variably sync data with the PDA, for example, when installed on the PDA, or at intervals or other selected times. In some such variations, an external power and other function extender and auxiliary protective housing may be variably coupled with the device  101 , when device  101  is not presently installed on a PDA or coupled to another device. Such function extender and auxiliary protective housings are discussed below, in reference to  FIG. 2 . However, even if no such auxiliary protective housing is included, a self-contained variable housing may be included in device  101  itself. For example, variably-extending, force-biased protective tabs  109  may variably deploy from slots variably storing them (not pictured) in main body  104 , when device  101  is uninstalled from a PDA, and surround or at least partially otherwise protect strip/pin  107 . Preferably, force-biasing tends to push protective tabs  109  as shown by force arrows  111 , but, owing to forward-leading slopes  113  (as device  101  is installed onto a PDA), tabs  109  are depressed into the slots within the main body  104  when device  101  is installed, keeping them out of the way for installation, and assisting in holding device  101  in place when installed, with the aid of flat, gripping surfaces  115 , which may at least partially comprise an elastomeric or otherwise gripping surface or texture. The outward surfaces of device  101  are generally sloped, creating a more streamlined and less noticeable profile when installed in the PDA. 
     Although device  101  is shown extending the abilities of a PDA or smartphone (“PDA”) through an Audio Jack, it should be understood that device  101  may be used to extend the abilities of a wide variety of alternative computer and computing device systems and networks, and a wide variety of plugs, pins, jacks and other communications or other receiving terminals, ports and fastening sections may also be used to carry out aspects of the present invention, some, but not all, of which will be discussed in greater detail, below. 
       FIG. 2  is a side view of a function extension component and auxiliary protective housing  201 , which may be variably coupled with a variably connectable peripheral device for a PDA, such as device  101 , discussed above. To install component and auxiliary protective housing  201  onto device  101  (and thereby couple the two) a user may thread component and auxiliary protective housing  201  over strip/pin  107  through Jack  202 . Through that interface, between Jack  202  and strip/pin  107 , device  101  and component and auxiliary protective housing  201  may then communicate via a (preferably) wired connection to accomplish some extension of function, although, in some embodiments, communications may also be achieved by other means, such as with local wireless networks. 
     Among other extensions of function, component and auxiliary housing  201  may provide off-board power for device  101 , for example, via a battery or other power source  203 . In addition, component and auxiliary housing  201  may include computer hardware, such as a central processor  205 , and any number of additional antenna(s), sensor(s), display(s), other actuator(s), or set(s) of such component(s), and connect them to device  101  allowing them to communicate with device  101 , and vice versa. In some embodiments, component and auxiliary housing  201  may be, itself, connected to another computer system (by a wired or wireless communications and/or power delivering connection), and may extend capabilities of that computer system to component and auxiliary housing  201  and/or device  101 . When installed onto (coupled with) device  101 , the outer surface  207  of component and auxiliary housing  201  may variably interlock with or otherwise interface with a structural component of device  101  in addition to surrounding strip/pin  107 , to provide greater rigidity and structural protection of strip/pin  107 . Outer surface  207  may comprise a light-weight, sufficiently strong material to better protect strip/pin  107  from environmental insult. Other functional extensions, and extension-enabling devices, may also be comprised in component and auxiliary protective housing  201 , such as a keychain loop  209 . 
       FIG. 3  is a rear view of a PDA  300  with a peripheral device system  301 , such as the device system discussed with reference to  FIG. 1 , above, installed into and able to communicate with the PDA through its Audio Jack  303 , in accordance with aspects of the present invention. Compared to the viewing angle of  FIG. 1 ,  FIG. 3  has been rotated 90 degrees counter-clockwise, on the downward vertical axis. From this rear view, the device  301  has its largest profile, but is still modestly sized in comparison to the PDA (preferably occupying no more than 75 to 90% of the PDA&#39;s width), and generally lays flat against the side  305  of the outer housing of the PDA that is closest to the viewer (visible, facing the positive Z-axis, out-of-the-page of the figure). In the installed position depicted, device  301 &#39;s Audio Jack-interfacing and mounting strip or pin  307  is mounted into Audio Jack  303 , and maintains electronic communication capabilities between the PDA  300  and the device  301 , as explained with respect to  FIG. 1 , between strip/pin  107  and device  101 . A horizontal inner side of the housing of device  301  (not pictured, but shown as  105  in  FIG. 1 ) abuts the top edge  309  of the PDA, in which Audio Jack  303  is embedded and opens from. One may also see the relative extension of the device  301 / 101 &#39;s own auxiliary Audio Jack  308 , which extends upward from the PDA and the remainder of device  301 / 101 , in order to create the necessary space to receive a phone plug, an example of which is shown as  311 , and to provide discrete, insulated electronic connections for each electronic lead of the phone plug to discrete, insulated electronic contacts of the device  301  and/or the PDA  300 &#39;s Audio Jack  303 . In turn, the strip/pin of device  301  may, itself, provide discrete, insulated electronic connections and discrete electronic leads to discrete, insulated electronic contacts of the PDA Audio Jack  303 . 
     As will be discussed in greater detail below, depending on the tolerances between particular Audio Jacks and phone plugs, the simultaneous insertion of a part of the plug into a strip or pin, such as that shown as  307 , and also within an Audio Jack may be difficult and costly to achieve from a manufacturing standpoint, as a universal approach for a wide variety of PDAs. Nonetheless, options for achieving such space-saving, at least partial simultaneous insertion of  307  and  311  are depicted in  FIGS. 7-9 . In another embodiment, however, discussed immediately below, that simultaneous insertion is not necessary to obtain some objectives of the present invention. 
       FIG. 4  is a rear view of the same PDA as that depicted in  FIG. 3  (now  400 ) with an alternate embodiment of a peripheral device system  401 , installed into and able to communicate with the PDA through its Audio Jack  403 , in accordance with aspects of the present invention. As an alternative also mentioned above, in this embodiment, the at least partially simultaneous insertion of a phone plug, such as the example pictured as  411 , into the inside of both the strip/pin (now  407 ) and Audio Jack (now  403 ) is not necessary. Instead, the device  401  includes an auxiliary jack  408  at a neighboring location, separate from the PDA  400 &#39;s Audio Jack  403 . Nevertheless, auxiliary jack  408  provides discrete, insulated electronic connections for each electronic lead of a phone plug to discrete, insulated electronic contacts of the device  401  and/or the PDA  400 &#39;s Audio Jack  403 , for, example, through more extended wiring or busses than would be necessary in embodiments discussed with reference to earlier figures, above. In turn, a strip/pin of device  401  may, itself, provide discrete, insulated electronic connections and discrete electronic leads to discrete, insulated electronic contacts of the PDA Audio Jack  403 . 
       FIG. 5  is a front view of the same PDA discussed in reference to  FIGS. 3 and 4  (now  500 ) with the same peripheral device system  501  as that shown in  FIG. 4  installed into and able to communicate with the PDA through its Audio Jack, now  503 , in accordance with aspects of the present invention. Compared to the viewing angle of  FIGS. 4 and 5 , device  401  and the PDA have been rotated 180 degrees, on the vertical axis. From this rear view, the device  501  is shown with a much smaller viewable profile, which is almost negligible to a user, but some important additional aspects may still be better understood. For example, a slight gripping overhang  517  of the device  501 &#39;s housing may be seen, which extends an inward-facing horizontal surface of device  501  (discussed previously as inward-facing side  105 ) vertically, downward, to a sufficient length that lateral (horizontal) pulling in of that overhang (into the page, negative Z-axis, from the perspective of the drawing) will result in pinching, gripping force against the edge  519 , and/or front side  521  generally, of the PDA  500 . As will be explained in greater detail below, some embodiments of the invention provide for applying such pinching, gripping force, on multiple sides or other parts of a PDA, to create superior mounting strength, while permitting the adjustment of the device  501  to fit a wide variety of PDA housing widths. 
       FIG. 6  is a side view of another embodiment of an exemplary peripheral device system  601  that may access the Audio Jack of a PDA, yet also provides external, additional access to the Audio Jack of the PDA, in accordance with aspects of the present invention. Device  601  is similar in profile and function to exemplary device  101 , as discussed above. However, in addition, device  601  comprises at least one force-biased telescoping joint  627 , connecting at least two laterally shiftable device sections: (1) a PDA-gripping device section  631  comprising a vertical, inward-gripping wall  605 , and (2) a strip/plug section  633 , comprising the strip/pin that may be variably inserted into an Audio Jack of a PDA. By creating inward-pinching lateral pressure, as shown by force arrows  629 , force-biasing joint  627  may create gripping, mounting and holding pressure between device  601  and a PDA on which it is installed. In addition, although not pictured, a second such lateral force-biasing, inward-gripping joint may also join a third device section (to the right of the other two, from the perspective of the figure), comprising a gripping overhang (such as the overhang discussed with reference to  FIG. 5 , immediately above), to provide additional inward, gripping force on the other side of the PDA (from the side gripped by section  1 / 631 ). As an added advantage, these force-biased joints and sections allow force-biased lateral play outward, as well as inward, between the sections and, as a result, device  601  may grip and hold itself in an installed position on a wide variety of PDA devices, with widely differing widths and profiles. 
       FIG. 7  depicts a side- and partial cutaway view of an exemplary embodiment of a pin or strip  701  of a peripheral device that may aid such a device in variably mounting to, and establishing electronic communications with, a PDA or other portable computing device with a complementary Jack. The exemplary embodiment set forth with reference to this figure is one of several alternative possible embodiments, some of which will also be discussed, subsequent to this figure, but which are not exhaustive of the many different forms that fall within the scope of the invention. For simplicity, in each of these figures, the remainder (other than the pin or strip) of the peripheral device is omitted, but it should be understood that each such pin or strip is physically connected to the remainder of such a peripheral device, and strongly enough bound to it to provide mounting pressure to secure the device to a PDA, when the pin or strip is inserted into the Audio Jack of a PDA. 
     The exterior surface  703  of pin/strip  701  comprises conventional audio plug contacts  705 , and insulating dividers  707  between those contacts. However, the interior of pin/strip  701  includes a partially hollow core  709 , capable of receiving another audio plug (not pictured) optionally by expanding during entry, as necessary based on plug size (which expansion may be facilitated by a longitudinal or other cutaway(s) in pin or strip  701 , and owing to the complementary inner contours of the core, capable of receiving such a plug. In addition, even though hollow core  709  preferably holds such an inserted plug in a position shifted away from the tip  711  of the pin/strip  701 , inner contacts  713  and insulating inner dividers, examples of which are shown as  715 , are placed in the correct position to make insulated, discrete contact with the outer surfaces of another audio plug, inserted in hollow core  709 . In addition, electronic conduits between contacts  713  on the inner surface of hollow core  709  and contacts  705  on the exterior surface  703  of the pin/strip  701  may permit an inserted plug to maintain electronic communication with a PDA in which pin/strip  701  is mounted. At the same time, electrical wires, shown partially comprised within device connection  717  (partially shown and partially cutaway to reveal the relationship and omit unnecessary complication and obstruction by the remainder of the connected device), may flow discretely between the remainder of the peripheral device (not pictured) and any or all of the contacts  705  and/or  713 , to selectively and discretely communicate with the PDA and/or inserted phone plug, as well as selectively relay signals between the phone plug and PDA, with or without further filtering, conditioning or other intermediate treatment of the signal. Alternatively (although not pictured, for simplicity in viewing) contacts  705  and  713  may be insulated from one another, but connected to the remainder of the device, which may so handle relaying and intermediate treatment of signals between the phone plug and PDA. 
       FIG. 8  depicts a perspective view of another exemplary embodiment of a pin or strip  801  of a peripheral device that may aid such a device in variably mounting to, and establishing electronic communications with, a PDA or other portable computing device with a complementary Jack. Pin or strip  801  comprises an at least semi-helical or otherwise wound, thin band with variable contacts and electronic leads, corresponding in position with the electronic contacts of an audio plug  803 , on which it is shown installed. More specifically, contacts  805  of pin/strip  801  are shown pressing against contacts  807  of the audio plug  803 . Insulation layers, such as the examples shown as  809 , electronically isolate contacts (such as contacts  805 ) from other contacts and leads therefrom and may also (depending on the exact type, shape and size of pin or strip  801  and the Audio Jack) prevent direct connection of an audio plug with the contacts of an Audio Jack, into which both pin/strip  801  and/or audio plug  803  may be installed. Preferably, pin/strip  801  may be installed into an Audio Jack with or without a plug, such as  803 , although, in some embodiments, a place-holding plug, or at least approximately phone plug-shaped and -sized filler, may be used in place of an audio plug, to maintain installation of pin/strip  801  into an Audio Jack in the absence of a plug, such as  803 . Pin/strip  801  is preferably thin enough to permit the full insertion (and, therefore, installation) of both an audio plug, such as  803 , and the pin/strip itself, but comprises sufficiently strong materials and structure to maintain installation of the remainder of a peripheral device, whether or not an audio/phone plug is also installed. Again, although a wound structure is shown for pin or strip  801 , it should be understood that a wide variety of alternative thin or otherwise minimally-interfering (with respect to Audio Jack function) structures may, alternatively or in addition, be used to mount and provide communications for a device to a PDA, and otherwise carry out aspects of the present invention. For example, pin or strip  801  may also comprise a lattice or interconnected basket, and other movable barbing or other protrusions to variably fasten a device to a PDA. 
       FIG. 9  depicts a perspective view of another exemplary embodiment of a pin or strip  901  of a peripheral device that may aid such a device in variably mounting to, and establishing electronic communications with, a PDA or other portable computing device with a complementary Jack. Pin/strip  901  comprises a straight, thin band  905  with variable contacts and electronic leads, corresponding in position with the electronic contacts of an audio plug, such as the example shown as  903 , on which it is installed, similar to the thin band discussed with reference to  FIG. 8 , except that it is in a straight, rather than helical, format. While the durability of this straight configuration of pin or strip  901  is desirable, it leads to the potential issue of uncontrolled lateral play when installed without a plug, such as  903  (or placeholder plug, as discussed above). To improve performance in this regard, two exemplary audio jack-interfacing rings are also provided:  907 , which is connected to the band  905  approximately ⅔ rds  of the way down its length, and  906 , which is shown connected with, and forms a part of, an Audio Jack-holding cap  909 , connected to the proximal end of the band  905 , and also connected with electronic lead out-port  911 , which provides a structural and isolated electronic connections (to each contact of band  905 ) to the remainder of the peripheral device (not pictured). Also shown reducing lateral play is a force-biased extension (e.g., springboard)  913 , which maintains a hold via outward pressure, on the inside of an Audio Jack in which it is installed. In some embodiments, additional variable fasteners, which may include grooves or other complementarily-interfacing features, may link pin or strip  901  with plug  903  and/or an Audio Jack. 
       FIG. 10  depicts another embodiment of an exemplary peripheral device system  1001  and its installation onto a PDA  1003  with a specialized wireless docking port  1007 , in accordance with aspects of the present invention. In some aspects of the invention, a local, secure wireless connection may be established between a peripheral device and another computer system (such as PDA  1003 ) by the peripheral device and/or the computer system initiating such a secure network upon detecting relative coordinates and/or physically connections and connection conditions of a precise matching value (the precision of which may be by a variable setting of the system, which may be variably set by the system and/or user). For example, exemplary peripheral device  1001  comprises a securing clamp  1005 , which may itself comprise two arms  1009  and  1011 , linked by a rotary joint  1013 . Clamp joint  1013  may comprise at least one actuator(s) and/or sensor(s) and/or a sensor/motor, and may be electronically connected to, and able to communicate with, a control system  1015 , which may comprise a computer hardware and software control system. An example of such a computer hardware and software control system is provided in reference to  FIG. 13 , below. Control system  1015  may also be electronically connected to, and able to communicate with, an antenna  1017 , such that the control system  1015  may communicate by sending encoded wireless signals, such as those examples shown as radio frequency waves  1019 , over a wireless network, and may also initiate protocols for establishing a local, wireless network. 
     Similarly, PDA  1003 &#39;s docking port  1007  (which may be an integral part or, or variably installed onto a PDA without causing permanent changes to the PDA) may comprise a physical actuator, in communication with a control system (not pictured). More specifically, docking port  1007  may comprise a variably-actuable tab  1020 , which may depress/extend, or be depressed by, a tab  1021  on arm  1011  of the peripheral device  1001 , which itself may be depressible/extendable variably-actuable by control system  1015 . PDA  1003  may have traditional WiFi and other antennas, such as WiFi antennas  1023  and  1025 . However, in addition, PDA  1003  may also comprise dedicated physical connection network antennas  1027 , for establishing shorter-radius (which may be much lower powered) and or narrow directional wireless networks between PDA  1003  and peripheral devices—specifically, peripheral devices that have established an interlocked physical connection with the PDA and/or some physical coordinates of precisely matching values and/or common physical actuation and interaction, required by the PDA and/or peripheral control systems to establish such a wireless connection. Physical connection network antennas  1027  may do more than complete such a wireless connection, however. By including two such antennas, focused on two coordinate axes—as pictured—they may also be used as coordinate rangefinders for the PDA, and thereby assist in establishing the protocols and initial requirements for initiating the physical connection network. In some embodiments, the speed with signals are returned, to each antenna  1027 , itself may be used by a control system to infer the coordinate location of the peripheral device  1001 , and determine whether it is in the coordinate position required to initiate communication (and the protocols for establishing a physically attached peripheral device network (a.k.a. physical connection network). Of course, a wide variety of additional or other positional and tab-actuation sensors and locators may, alternatively, be used to establish that the required docking position of a peripheral device system is present, and thereby triggering the initiation of a secure focused peripheral device network for establishing a secure wireless or otherwise restricted, protected network from intercession or other unauthorized aspects. In some embodiments, positional sensors on or about port  1020  or the PDA  1003  may receive multiple inward-facing position-indicating signals from system  1001  and, preferably, from at least two originating points surrounding the PDA on multiple sides, by directional sensors (or vice versa, with sensors on the system) to confirm the physical location of the peripheral device, triggering the granting of peripheral device network creation and/or access. Such network access may still be maintained with encryption, via protocols carried out by the system  1001  and PDA  1003 , and the standards and other aspects of such protocols and encryption routines (such as passwords) may be briefly exchanged for creation of the peripheral device network only. 
     In some embodiments, both a wireless and wired connection may be maintained between PDA  1003  and peripheral device  1001 , via physical contacts in port  1007  as well as antennas  1027  and  1017 . In still other embodiments, a wireless connection, or a greater strength and constancy or less restricted in direction wireless network (as in a personal area network or WiFi) may be initiated upon decoupling peripheral device  1001  and PDA  1003 . In this embodiment, the encryption key and other initiation and other protocols for creating and/or maintaining the network may be exchanged between the PDA and peripheral device just prior to disengagement, upon detecting initiated disengagement. Electronic contacts that maintain some connection for an amount of time sufficient for that transfer even while undergoing disengagement may be used for that purpose, or the protocols may be shared in advance, or a limited, short (e.g., unencrypted) protocol for that purpose may be exchanged just prior to and after initiation of disengagement, with the remainder of the required secure protocol being exchanged over a temporary, short distance network sufficient to accomplish exchange after disengagement, and, after expiry, the two devices may create the more permanent network using the exchanged protocols. This principle may be applied for the establishment of local networks for any other types of devices that are initially in hardwired communication but, after disengagement, may still require local network connection. Formally setting up such a connection can be painstaking, and users have already established trustworthiness to access the network by being granted permission to hardwire into the network. Thus, this aspect uses the fact of former hardwiring as evidence sufficient to grant encrypted wireless access, without further nuisances. 
       FIG. 11  depicts the front of an exemplary tablet or other computer console  1101 , with an active matrix display screen  1103 , and a specialized network transceiver device  1105  for the establishment of a peripheral device network, in accordance with aspects of the present invention. Device  1105  may include a directional antenna, sensors, or an array of antennas and sensors for establishing, as discussed above with reference to antennas  1027 , positional, device orientation and device physical interrelation triggered peripheral device networks. Once again, device  1105  is capable of determining unique locational information of a precision that is extremely difficult, if not impossible, to replicate with a hacking device, and may trigger and maintain a directionally restricted (in space) network exchange (signal directions emerging from both the console  1101  and any networked provisional device being so directionally restricted. In addition, shielding and reflectors in console  1101  and/or such a peripheral device may prevent leakage of the peripheral device network signals beyond the confines of their housings and serve to further confirm the authorized positioning and state of the peripheral device (not pictured in this figure. 
       FIG. 12  depicts a new form of peripheral device  1201 , which is a variable display overlay for altering the display type or otherwise augmenting the output of a display, such as the display  1103  of console  1101 , in  FIG. 11 . As with other peripheral devices for extending the capabilities of PDAs, consoles and other computer systems, device  1201  may comprise its own on-board CPU  1203  and other computer system aspects, such as an output and/or display driver  1205 , and power source, but may, alternatively, derive power from an ambient source, and/or a connected console (such as  1101 ). To couple device  1201  with a console  1103  which it will serve as a peripheral device, and establish a peripheral device network, a user need only overlay peripheral device  1201  onto the screen (such as  1103 ) of a console  1101 . By virtue of doing this, and, optionally, connecting a fastener (for example, magnetic clamp  1207 ) the console  1101  and/or device  1201  may mutually establish a precise directional collocation and orientation through a routine that excludes external interference (such as the protocols and routines discussed above for so establishing such peripheral device networks). For example, directional signals from two originating points/antennas  1208  and  1210 , may provide the contained, multiple-directional signals required to satisfy directional efference conditions for establishing the peripheral device network, of directional transceiver  1105  and console  1101  (or vice versa). Because  1208  and  1210  may surround console  1101  on multiple sides, their signals may satisfy that exemplary requirement, discussed above, for establishing a peripheral device network. As a result, console  1101  may then authorize and be authorized to drive and control the output of an overlaid display  1209  of device  1201 , and vice versa. 
     For example, device  1201  may create a specialized display output that is easier to read in highly illuminated ambient conditions—such as an e-ink display. Because console  1101  may have an LCD display, by contrast, it may be very difficult to view in such highly illuminated environment. As such, it may be desirable to overlay device  1201  onto console  1101 , creating a peripheral device network between the two, after which point console  1101  may direct (and, optionally, provide power, which may be ambient power, for example, from its illuminated display) device  1201  to display the same information as would be displayed on its own display  1103 , on the device display  1209 . Conversely, device  1201  may instruct console  1101  to power down its display, to avoid wasting power, and perform other such management tasks (in reverse) of the console  1101 . As another example, display  1109  may comprise galvanic resistance or other screen actuation transmitters or sensors, to transmit actuation gestures from a user to a console  1101 . Such a device may, alternatively or in addition, be hardwired to a console  1101  and, in some embodiments, sensors on the inside (opposite the viewer) of display  1209  may instead read, transmit or amplify radiation or information from the screen  1103 , transmitting a similar image through to the other side (facing the viewer of the figure). 
     The peripheral devices specifically discussed herein are exemplary only, and it should be understood that a wide variety of alternative peripheral devices, for virtually unlimited tasks and capabilities extensions may, alternatively or in addition, be used. In some embodiments, multiple peripheral devices may be established in the same peripheral device network or, alternatively, multiple peripheral device networks may be formed. 
       FIG. 13  is a schematic block diagram of some elements of an exemplary control system  1300  that may be used in accordance with aspects of the present invention, such as, but not limited to, actuating sensors, motors, transceivers (including, not limited to, directional antennas and receivers), network protocols, secure encryption variable electrical connections, controlling and powering display and other devices, such as, but not limited to PDAs, and other actuators and/or signal an informational systems. The generic and other components and aspects described herein are not exhaustive of the many different systems and variations, including a number of possible hardware aspects and machine-readable media that might be used, in accordance with the present invention. Rather, the system  1300  is described to make clear how aspects may be implemented. Among other components, the system  1300  includes an input/output device  1301 , a memory device  1303 , storage media and/or hard disk recorder and/or cloud storage port or connection device  1305 , and a processor or processors  1307 . The processor(s)  1307  is (are) capable of receiving, interpreting, processing and manipulating signals and executing instructions for further processing and for output, pre-output or storage in and outside of the system. The processor(s)  1307  may be general or multipurpose, single- or multi-threaded, and may have a single core or several processor cores, including, but not limited to, microprocessors. Among other things, the processor(s)  1307  is/are capable of processing signals and instructions for the input/output device  901 , analog receiver/storage/converter device  1319 , analog in/out device  1321 , and/or analog/digital or other combination apparatus  1323  to cause a display, light-affecting apparatus and/or other user interface with active physical controls, such as a charging station pump (any of which may be comprised or partially comprised in a GUI) to be provided for use by a user on hardware, such as a personal computer monitor or PDA (Personal Digital Assistant) screen (including, but not limited to, monitors or touch- and gesture-actuable displays) or terminal monitor with a mouse and keyboard or other input hardware and presentation and input software (as in a software application GUI), and/or other physical controls. Alternatively, or in addition, the system, using processors  907  and input/output devices  1319 ,  1321  and/or  1323 , may accept and exert passive and other physical (e.g., tactile) user and environmental input and output. 
     For example, and in connection with aspects of the invention discussed in reference to the remaining figures, the system may carry out any aspects of the present invention as necessary with associated hardware and using specialized software, including, but not limited to, controlling secure wireless and hardwired peripheral device networks and other communications, and implementing controls and power effectuated through such network system, and the networked devices or other computer systems. The system may also, among many other things described for control systems in this application, respond to user, sensor and other input (for example, by a user-actuated GUI controlled by computer hardware and software or by another physical control) to activate/deactivate recharging systems and pumps, store batteries and monitor their status in an inventory, exchange batteries and determine net power, capacity and other exchanges with users, or perform any other aspect of the invention requiring or benefiting from use of a control system. The system  1301  may also permit the user and/or system-variation of settings, including but not limited to the affects of user activity on modes of operation of the system, and send external alerts and other communications (for example, to users and administrators) via external communication devices, for any control system aspect that may require or benefit from such external or system-extending communications. 
     The processor  1307  is capable of processing instructions stored in memory devices  1303  and/or  1305  (and/or ROM or RAM), and may communicate with any of these, and/or any other connected component, via system buses  1375 . Input/output device  1301  is capable of input/output operations for the system, and may include/communicate with any number of input and/or output hardware, such as a computer mouse, keyboard, entry pad, actuable display, networked or connected second computer, other GUI aspects, camera(s) or scanner(s), sensor(s), sensor/motor(s), range-finders, GPS systems, receiver(s), transmitter(s), transceiver(s), transflecting transceivers (“transflecters”), antennas, electromagnetic actuator(s), mixing board, reel-to-reel tape recorder, external hard disk recorder (solid state or rotary), additional hardware controls (such as, but not limited to, buttons and switches, and actuators, current or potential applying contacts and other transfer elements, light sources, speakers, additional video and/or sound editing system or gear, filters, computer display screen or touch screen. It is to be understood that the input and output of the system may be in any useable form, including, but not limited to, signals, data, commands/instructions and output for presentation and manipulation by a user in a GUI. Such a GUI hardware unit and other input/output devices could implement a user interface created by machine-readable means, such as software, permitting the user to carry out any of the user settings, commands and input/output discussed above, and elsewhere in this application. 
       1301 ,  1303 ,  1305 ,  1307 ,  1319 ,  1321  and  1323  are connected and able to communicate communications, transmissions and instructions via system busses  1375 . Storage media and/or hard disk recorder and/or cloud storage port or connection device  1305  is capable of providing mass storage for the system, and may be a computer-readable medium, may be a connected mass storage device (e.g., flash drive or other drive connected to a U.S.B. port or Wi-Fi) may use back-end (with or without middle-ware) or cloud storage over a network (e.g., the internet) as either a memory backup for an internal mass storage device or as a primary memory storage means, or may simply be an internal mass storage device, such as a computer hard drive or optical drive. 
     Generally speaking, the system may be implemented as a client/server arrangement, where features of the invention are performed on a remote server, networked to the client and made a client and server by software on both the client computer and server computer. Input and output devices may deliver their input and receive output by any known means of communicating and/or transmitting communications, signals, commands and/or data input/output, including, but not limited to, input through the devices illustrated in examples shown as  1317 , such as  1309 ,  1311 ,  1313 ,  1315 , and  1377  and any other devices, hardware or other input/output generating and receiving aspects. Any phenomenon that may be sensed may be managed, manipulated and distributed and may be taken or converted as input or output through any sensor or carrier known in the art. In addition, directly carried elements (for example a light stream taken by fiber optics from a view of a scene) may be directly managed, manipulated and distributed in whole or in part to enhance output, and whole ambient light or other RF information for an environmental region may be taken by a series of sensors dedicated to angles of detection, or an omnidirectional sensor or series of sensors which record direction as well as the presence of electromagnetic or other radiation. While this example is illustrative, it is understood that any form of electromagnetism, compression wave or other sensory phenomenon may include such sensory directional and 3D locational information, which may also be made possible by multiple locations of sensing, preferably, in a similar, if not identical, time frame. The system may condition, select all or part of, alter and/or generate composites from all or part of such direct or analog image or other sensory transmissions, including physical samples (such as DNA, fingerprints, iris, and other biometric samples or scans) and may combine them with other forms of data, such as image files, dossiers or metadata, if such direct or data encoded sources are used. 
     While the illustrated system example  1300  may be helpful to understand the implementation of aspects of the invention, it is understood that any form of computer system may be used to implement many control system and other aspects of the invention—for example, a simpler computer system containing just a processor (datapath and control) for executing instructions from a memory or transmission source. The aspects or features set forth may be implemented with, and in any combination of, digital electronic circuitry, hardware, software, firmware, or in analog or direct (such as electromagnetic wave-based, physical wave-based or analog electronic, magnetic or direct transmission, without translation and the attendant degradation, of the medium) systems or circuitry or associational storage and transmission, any of which may be aided with enhancing media from external hardware and software, optionally, by wired or wireless networked connection, such as by LAN, WAN or the many connections forming the internet or local networks. The system can be embodied in a tangibly-stored computer program, as by a machine-readable medium and propagated signal, for execution by a programmable processor. The method steps of the embodiments of the present invention also may be performed by such a programmable processor, executing a program of instructions, operating on input and output, and generating output. A computer program includes instructions for a computer to carry out a particular activity to bring about a particular result, and may be written in any programming language, including compiled and uncompiled, interpreted languages, assembly languages and machine language, and can be deployed in any form, including a complete program, module, component, subroutine, or other suitable routine for a computer program.
