No. 62/102,022, titled “Mobile Device Sled With Novel Port Usage and Standing Configuration for Ready Pairing Between a Mobile Device and Associated Peripheral Devices as filed on Jan. 10, 2015, the entirety of which is hereby incorporated by reference. 
    
    
     1. FIELD OF THE INVENTION 
     The present invention relates to an apparatus and method for operative physical cooperation between a mobile phone, tablet or the like, and an associated peripheral device such as barcode scanners and payment terminals, and improved methods for both physically combining the above and for electronically connecting the same, and for providing ports and mechanical structures which improve user ergodynamics. 
     2. DISCUSSION OF THE RELATED ART 
     Mobile devices or terminals such as smart phones, tablets and the like are becoming widely used as more than mere communication or media devices. There are a variety of field applications for such mobile devices that may be advantageously effectuated through the use of peripherals that can be connected thereto. 
     Despite such advantages, when a given mobile device is connected to certain peripheral devices, effective operation between the same is often limited by the fact that it is difficult to use the devices at the same time, especially given the need to maintain proximate electronic connectivity ranges and also because of the physical limitations inherent in trying to manually hold or manipulate all of the above at the same time during the course of operation by an end user. 
     Because of the above challenges, current approaches for using any of the above devices have been hitherto limited to employment of awkward physical and electronic connections required for the simultaneous use and connection of the peripheral devices that a user may wish to associate therewith. Additionally, certain special purpose peripheral devices such as handheld barcode scanning devices and/or payment terminals currently are particularly difficult to use with tablets and mobile phones, thereby limiting their effective field deployment in industries such as retail, logistics, medical institutions, warehousing, transportation, entertainment and sporting venues. Additionally, such devices often do not have effective ports for connections, nor do the user ergodynamics provide for ease of use, particularly across a variety of field environments, including but not limited to retail, office, warehouse, transportation and medical environments, and the like. 
     SUMMARY OF THE INVENTION 
     The present invention is, in one embodiment, directed to a mobile device and peripheral device consolidation system and method for providing improved interoperability between a mobile device and a peripheral device. More particularly, the present invention is directed to a system and method for providing both a physical and electronic approach to enabling a mobile device such as a mobile phone or tablet, to be readily and conveniently paired with a peripheral devices such as bar code readers and payment terminals in a way that substantially obviates one or more problems due to limitations and disadvantages of the related art. 
     Additionally, the proposed invention pertains to a novel approach to physically attaching any of the aforementioned to each other in a convenient, modular fashion that can be used in a standing configuration. In doing so, the present inventive approach utilizes a plastic or metal structure or housing that can readily attach to the back of a mobile device, yet can also house or readily accept a peripheral device as an attachment thereto, yet during usage extends out as stabilizer leg in order to provide a standing configuration for ease of use. Perhaps more importantly, though, in one optional instantiation, devices. The inventive approach is therefore especially valuable in that permits usage of mobile phone (e.g., smart phones) and tablets or the like with a handheld barcode scanning device, a payment terminal (MSR, chip reader, etc.), or other peripheral apparatus in a wireless, physically compact and consolidated fashion that requires little or no set up and integration or configuration, and furthermore, offer the ability to effectuate operation of such peripheral devices through either their native operation button situated thereon or, for ease of access when mounted on the inventive sled, through an external sled operation button. This special feature, it might be noted, is afforded through native USB connections by novel provision of a special purpose programmed circuit in the sled that contains a smart multiplexer logic core that can accept a configuration from either external software or scanning operation, processed from a peripheral device CPU, and as accessed via the aforementioned native USB connections. 
     Accordingly, the present invention offers for the following beneficial advances relating to providing a mobile device and peripheral device consolidation system for providing improved interoperability between a mobile electronic device and a peripheral device through: (1) provision of a “sled” that includes a novel attachment and detachment structure that permits standalone peripheral devices such as barcode scanners and payment terminals to be physically consolidated with all types of mobile electronic devices, including smart phones and larger size devices such as tablets in a convenient, stream lined, user-friendly way; (2) provision of a sled with modular physical capacity for ready attachment and detachment of the aforementioned bar code readers (scanners) and/or a payment terminals as desired; (3) a sled with an upright standing configuration option; (4) a sled that provides users with the option to seamlessly use either the native operation (e.g., scan) button existing on a barcode reader, or an external operation or scan button on the sled that readily controls the aforementioned bar code reader, and furthermore, does so without conflict between the existing circuitry relating to the native button; (5) a sled that provides for the innovative use of USB connections for leveraging the same in order to provide display-free configuration of the aforementioned scan button options; (6) provision of an improved swing-out USB connection; (7) provision of a modular payment terminal rotating connection which provides for automatic rotation of the display of a payment terminal through at least 180 degrees of rotation in order to maximize the usability when attached to the sled, as well as when detached from the sled; (8) enabling a user, through the inventive modular architecture, to change smart phones/cell phones (as well as peripherals such as the compact bar code reader and/or payment terminal) periodically, without replacing the inventive sled. 
     Technical subject matters to be realized by embodiments of the present invention are not limited to the following technical subject matters, and other technical subject matters not mentioned in the following description may be easily appreciated by those skilled in the art to which the present invention pertains, without difficulty. Accordingly, additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following may be learned from practice of the invention.

No. 8,832,323, titled “Connectivity Sled for Electronic Pairing and Physical Cooperation Between a Mobile Device and Associated Peripheral Devices”, Issued Sep. 9, 2014, and pending U.S. patent application Ser. No. 14/219,920, titled “Mobile Device With Improved Charging Capability and Casement Structure”, filed Mar. 19, 2014, and pending U.S. patent application Ser. No. 14/153,006, titled “modular Payment Terminal Sled with Automatic Identification Capability”, all of which are hereby incorporated by reference in their entirety. 
     Reference will now be made in detail to the illustrative embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Constituent components and operations of the present invention shown in the drawings will be disclosed only for illustrative purposes of the present invention, such that technical spirit, important constructions and operations of the present invention are not limited to only the following embodiments, and can also be applied to other embodiments. 
       FIGS. 1A-1E  illustrate an example of one illustrative embodiment of the inventive mobile device and peripheral device consolidation system  1  with one embodiment of a standing configuration for providing improved interoperability between a mobile device and a peripheral device.  FIG. 1A , for example, details an illustrative configuration showing the novel modularity of mobile device and peripheral device consolidation system  1 , wherein a peripheral device such as barcode scanner  110  may be wholly detachable from modular sled  100 , and peripheral devices such as payment terminal  120 , attachable via a sliding guide  140  and also potentially releasable by pressing of a release button  105  or the like so as to activate a spring loaded latch, may perform a dual function as a standing leg (foldable standing configuration member) for propping up mobile the entirety of device and peripheral device consolidation system  1  in such a way so as to offer novel, improved user ergodynamics as a standing configuration  130 , as also seen in  FIG. 1B , if not completely detached therefrom. The additional novelty of improved ports provisioning is illustratively seen in  FIG. 1C , wherein a hardwired (as opposed to optional wireless) connectivity is shown, that of USB male connector  160  and female USB connector slot  162  for connecting a peripheral such as barcode scanner  110  to modular sled  100 . Optionally, a protective cap  190 , as illustratively shown in  FIG. 1D  may provide ruggedized structure for delicate peripherals such as barcode scanner  110 , a simple but important feature for certain rough environments, but one which is not found in known devices.  FIG. 1E  further shows an optional locking mechanism  192  for securing peripheral devices, also a simple but heretofore novel feature for mobility purposes and usage of mobile device and peripheral device consolidation system  1  in rugged environments. As depicted collectively therein, an inherent part of modular sled  100  portion of the present invention comprises (at least one) peripheral device (illustratively indicated as barcode scanner  110  and/or payment terminal  120 ) physically consolidated or connected with mobile device  171  via an attachment means (at least part of modular sled  100 , also termed sled  100 ) having a port  161 , the attachment means for attaching the at least one peripheral device to mobile device  171 , as well as provides for electronic connection between the respective devices, as described hereafter. The peripheral devices that may be attached to modular sled  100  may be of any type of at least one of the following peripheral devices comprising: compact bar code readers, MSRs, charging bases, IC card readers, peripheral device triggers, RFID tag readers, biometric verification modules, and/or multi-threat monitors, but for purposes of illustration in this particular example, a compact bar code reader  110  is shown in  FIGS. 1A-1E . Those skilled in the art will appreciate that various modifications, additions and substitutions are possible from this description, but in general, mobile device  171  is of the type chosen from the groups comprising mobile phones, smart phones, tablets, PDAs, and the like. In any case, mobile device  171  may be connected in a wired fashion (having physical wired contacts or connections, not depicted), or alternatively, in a wireless fashion to the peripheral device connected to the inventive sled through a protocol such as the illustrative Bluetooth® protocol. 
     With further, more detailed reference to  FIG. 1 , note that sled  100  (also termed herein modular sled  100 ), is indicated as an illustrative variant of the present invention which supports attachment of both detachable barcode scanner and detachable payment terminal to tablets. Although this is equally applicable to smaller frames, such as found in smart phones, the tablet is illustrated herein because tablets are normally larger than say 8 inches, and are difficult to use with attachments, so the novel approach to attaching the barcode scanner and payment terminal herein is described as such so as to show its novel structural versatility across various devices. Sled  100  supports barcode scanner  110 , as well as payment terminal  120 , wherein Payment terminal  120  has an LCD screen with a secure touch sensor as required according to PCI (Payment Card Industry) security standards, and IC Card  170 , MSR  180  and Near Field Communication (NFC)  195 . Payment terminal  120  would be inserted into payment terminal slot  125  (or other member) and can be unfolded to support standing configuration  130 . Payment terminal  125  can be folded to be used as mobile configuration. As illustrated, the folding and unfolding of payment terminal  125  member is one illustrative example of the novel standing configuration for use when an upright device orientation is desired, and for better access of peripheral device functionality in the field. As can be appreciated, the novel standing configuration can utilize other parts (members) of the sled structure instead of, or in addition to, the illustrative payment terminal  125 . Also, the novel standing configuration is part of the innovative ergodynamics described herein, and can be aided with use of a hinge and/or spring and/or locking mechanisms for (foldable) opening and closing. Credit cards having magnetic strips would be read by MSR  180  upon passing through MSR Sliding Guide  140 . Barcode scanner  110  would be activated by pressing scan buttons  150  and  151  on each side. In other embodiments, barcode scanner  110  and/or payment terminal  120  can be attached to sled  100  using following optional methods: (i) where sled  100  is configured with a pocket, sliding engagement arrangement, or slot for retention of Barcode scanner  110  and/or payment terminal  120 ; (ii) sled  100  has a USB Type “A” female connector, and securely holds Barcode scanner  110  and/or payment terminal  120  through engagement with built-in USB Type “A” male connector; (iii) sled  100  has a locking mechanism, such as a hood or magnetic to hold Barcode scanner  110  and/or payment terminal  120  securely. Alternatively, sled  100  may be provided with a locking mechanism with a release button  105 , supported by an internal spring. in such a configuration, payment terminal  120  would therefore be locked automatically upon inserting into sled pocket  125  for payment terminal  120 , and whereby payment terminal  120  would be released upon pressing push button  105 , although this aspect may be dispensed with in some embodiments, or replaced with other attach/detach approaches as required. Additionally, barcode scanner  110  may be optionally enclosed by a water protection cap or protective cap  190  in order to provide water and/or dust proof configuration. 
     Broadly speaking, the inventive modular approach therefore may use three component parts as an independent system and/or as a compact barcode reader by itself with or without an MSR. This modularity can facilitate ongoing use of the system with little to no modifications or configurations in the case of where a user desires to switch or replace a given mobile device. Moreover, the actual design of the modular sled is such that it can be used on all types of mobile devices, without blocking the mobile device communications and/or charging ports, and also supports all manner of native services, even those from specialized smart devices, such as iTunes®-type devices made by from Apple, Inc. of Cupertino, Calif. To this end, the present invention overcomes the aforementioned and other disadvantages inherent in the prior art. In doing so, all of the above permits for electronic communication between all devices in a variety of ways, including according to wireless communication means, such as a connection via a Bluetooth®-protocol based connection available from the Bluetooth SIG Inc., of Kirkland, Wash. 
       FIG. 2  shows an illustrative electronic schematic of the scan button selection of barcode scanner  110  in one embodiment. As depicted therein, USB  230  has Ground, 5V, and two communication signals—D− and D+. Normally, USB  230  cannot support a scan button on barcode scanner  110  and external scan buttons  150 ,  151  on sled  100 . However, the innovative approach as described herein overcomes this limitation to provide unexpected functionality. Scan buttons  150 ,  151  have switches  210 ,  220  inside and are connected to USB D-signal  370 . Button selection multiplexer (MUX) logic  240  decides the configuration of USB  230  as the standard USB port, or as proprietary logic external scan buttons  210  and  220  according to internal logic therein. 
       FIG. 3  depicts an illustrative electronic schematic of the USB and external button selection MUX in one embodiment. This illustrative embodiment shows one example of a detailed circuit diagram of USB and external button selection MUX logic. External switches  210  and  220  are connected to USB_DM_BUTTON signal  310 . SAM7_PPR#_MUX selection signal  320  is generated by barcode scanner  110  CPU. SAM7_PPR#_MUX selection signal  320  can be programmed by scanning special barcode using barcode scanner  110 , programmed by a sequence of barcode scanner  110  native buttons or by using an external software program that controls barcode scanner  110 . USB_DM_BUTTON signal  310  would be treated as a regular USB_DM signal  350  if the USB configuration is selected. Conversely, USB_DM_BUTTON signal  310  would be treated as KEY_SCAN# signal  340   l  if the external button configuration is selected by the user. KEY_SCAN# signal  340  in barcode scanner  110  would be generated by pressing either switches  210  or  220 , if SAM7_PPR#_MUX selection signal  320  is configured as external button configuration. This process is also described in a high-level flow diagram fashion, from beginning to end, in  FIG. 5 , specifically detailing at least some of the following illustrative steps of: (i) ascertaining whether instructions for executing button configuration selections been received at special purpose CPU, at step  502 ; (ii) load the special purpose CPU with instructions for executing button configuration selections, at step  504 ; (iii) transmitting instructions for executing button configuration selections to a special purpose multiplexer, at step  506 ; (iv) carrying out instructions for executing button configuration selections at special purpose multiplexer, at step  508 ; and (v) Utilize instructions for executing button configuration selections to utilize a USB port as a communications port when instructions indicate an External Button selection or as a regular USB port when instructions indicate a Native Button selection, at step  510 . 
     Further to the preceding paragraph, mobile device  171  may be of the type chosen from the groups comprising mobile phones, smart phones, tablets, PDAs, etc. and will generally include a display for implementing interactivity with a user, while illustratively, the compact bar code scanner  110  described herein may be any one of various types, such as that found in the illustrative KDC®  550  type unit, available from KoamTac® Inc., of Princeton, N.J. It is worth noting, that, when choosing a compact bar code scanner as peripheral device  10 , one generally would need to employ a bar code scanner  110  with programming capability activated through a specific “button selector” barcode (as further discussed below), or the ability to function with KTSync® type software downloaded therein, in order to provide the configuration options that enable a user to choose between employment of a native operation (scan) button, or the external sled operations (scan) button. Accordingly, a user may choose between employment of a native operation (scan) button, or the external sled operations (scan) button by, in one embodiment, employing the bar code scanning unit with programming capability activated through a specific “button selector” barcode as mentioned above. In such an embodiment, two illustrative bar codes may be employed, one customized “external button” bar code to be read for effectuating usage of the external sled button (while contemporaneously altering the functionality of the natural USB ports to accept the signals depicted in  FIG. 2 ), and another customized “native button” bar code to be read for continued usage of the external sled button and maintenance of regular USB port functionality. In this operative approach, known herein as “customized bar code-based button effectuation”, the logic for discerning between the aforementioned customized bar codes as scanned, and thereafter, executing the respective steps to carry out the desired approach to operational button usage by the user, are accomplished through the use of special purpose logic that resides in (special purpose) CPU  239 . When provided in this manner, the operational button, as part of a special purpose machine, transforms a physical push on the given selection by a user into a useful result relating to either a connection based upon a standard USB port usage; or as a proprietary external scan usage, and thereafter, an industrial application as described herein. Ensuing usage of the same means that results such as native scans or external scans yield respective bar code sequences from reflected laser light upon visually printed or displayed indicia as desired through a selected unit. Alternatively, the user can, by utilizing the same CPU and cooperative elements associated therewith as described, utilize KTSync® type software downloaded therein, in order to provide the configuration options that enable a user to chose which button (native or external) configuration he desires. Either way, the output from this process causes barcode scanner  110  to output, store and as needed, transmit a barcode sequence output that is then correlated to effectuation of industrial physicalities, namely practical applications such as product stock levels when used in logistics and warehousing applications, medical records and therapeutic administrations when used in medical applications, product inquiries and subsequently with usage of payment terminal  120 , purchases when used in the retail field of applications, running an assembly line in manufacturing applications, access controls for items and/or individuals when used in security applications, etc. At its highest level then, it may be said that for one embodiment, instructions (in one embodiment including configuration instructions) are received from the aforementioned special purpose CPU  239 , wherein the further include the step of causing an output, received from a barcode scanner  110  via said USB port, of a barcode sequence output, said output then effectuating at least one industrial application, such as one of the above as listed, or potentially others. As can be appreciated, such industrial applications are legion and the above is not meant to be limiting in any regards. 
     Considering the above, one particular point of novelty in the present invention therefore pertains to the ability to configure the sled  100  and attached peripherals (barcode scanner  110 , payment terminal  120 , etc.) without the use of a display. For instance, electronic operability between all such devices requires configuration. Configuration of interconnected devices of any kind in general requires connecting to a PC or the like, and often necessitates the use of a screen and user input devices in order to configure the same, something which can be tiresome and inconvenient. In the novel amalgamation of devices described herein, this need for display-based configuration is no different, but the present invention provides, in one embodiment, for a novel display-free configuration through configuration instructions. As referenced above, this can be accomplished by configuring according to either usage of a native mobile device configuration utility or through the use of scanning of special barcodes. External scan button is provided on the sled in order enhance the scanning convenience because the native operation (scanning) button may not be readily accessible when attached to sled  100 . The configuration of this External scan button is provided through the already-existing USB connection and ports, and in one embodiment, without the need for additional, specialized circuitry beyond that which is also disclosed herein, as the USB circuitry is used to transmit the External button configuration signals per  FIG. 3 , in addition to supporting normal USB communication signals. It is therefore quite novel that one USB port can support both external scan buttons, as well as USB communication. Accordingly, the USB/External button selection logic  310  is novel and a desired selection signal can be programmed by scanning a special barcode, and/or through novel internal/external programming supplied natively. Note that this logic, just like the special purpose CPU  239  and the special purpose MUX logic core, are, in one embodiment, all situated within barcode scanner  110 . By contrast, in another embodiment, one could place the MUX logic core within sled  100 , outside barcode scanner  110 , in wireless communication therewith, however, such an approach may be less efficient that the former approach. Additionally, special Bluetooth® management software such as the KTSync® software, also available from KoamTac® Inc., of Princeton, N.J. may also be employed to effectuate provision of the above as further described herein. 
     As seen in  FIGS. 4A-4B , Payment terminal  120  has, in one embodiment, a Barcode, MSR, Chip and PIN and NFC features. MSR header  420  may be positioned at the bottom of Payment terminal  120  so that users can swipe the card while the payment module is attached inventive sled  100  and put on top of a table or other flat surface  130  in (foldable) standing configuration for ease of use. IC Card reader  430  would be positioned at the top of Payment terminal  120  so that users can insert their credit card through  440  while the payment module is attached to inventive sled  110  and put on the top of table in standing configuration  130 . Payment terminal  120  would have Power  450 , Ground, TxD and RxD signals and mounting holes  460  for Barcode Module  470 . It is sometimes easier to read the magnetic strip from the top of Payment Terminal  120  and IC card from the bottom of Payment Terminal  120  if detached and used separately (perhaps with wireless communication option as described above), and as depicted herein, is offered in one embodiment as readily detachable, and thereafter, readily (re)attachable together with sled  100 . 
     Accordingly, while the illustrative sled supports detachable payment terminal  120 , but this beneficial feature is compromised by the structural fact that which payment terminal  120  is left with limited orientation due to the standing configuration  130  option. Therefore, a novel feature of the present invention overcomes this shortcoming by providing for payment terminal  120  to rotate the display by 180 degrees in order to maximize the usability between the different resulting viewability when attached to the sled and detached from the sled, as seen in  FIG. 4  which shows the different configurations of novel payment terminal  120  across the 180 degree transition of the viewing screen. In one embodiment, payment terminal  120  may be chosen from the group comprising an illustrative KDC 550 unit, available from Koamtac, Inc. of Princeton N.J. In such a novel payment terminal  120  as found illustratively in the KDC 550 unit, it recognizes detachment from (tablet variant of) sled  100  by internal proximity sensor or payment terminal  120  connector for sled  100 . Alternatively, payment terminal  120  can detect the connection via motion sensors, power connector, USB connector, magnetic sensors, proximity sensors. Once detachment is sensed, payment terminal  120 , through its automatic logic built therein, it can reverse the display upon detection of the detachment from sled  100 . Thus, payment terminal  120  would rotate the screen 180 degrees once detached from the sled  100  so that user can swipe the magnetic strip from the top and read IC card from the bottom. Similarly, payment terminal  120  with its optional display, returns to its original orientation upon connecting (placed back) to sled  100 . When provisioned as such, payment terminal  120  is configurable through at least one of the following of: via a USB connector when attached to sled  100 ; via a native configuration when not attached to sled  100 ; or via a simple power connection, such as a pogo pins or the like. 
     Having described the basic concept of the invention, it will be apparent to those skilled in the art that the foregoing detailed disclosure is intended to be presented by way of example only, and is not limiting. Various alterations, improvements, and modifications are intended to be suggested and are within the scope and spirit of the present invention. Additionally, the recited order of the elements or sequences, or the use of numbers, letters or other designations therefore, is not intended to limit the claimed processes to any order except as may be specified in the claims.
