CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation-in-part of and claims priority from U.S. patent application Ser. No. 13/177,465, titled “Connectivity Sled for Electronic Pairing and Physical Cooperation Between a Mobile Device and Associated Peripheral Devices” as filed on Jul. 6, 2011, the entirety of which is hereby incorporated by reference. 
     
    
     1. FIELD OF THE INVENTION 
       [0002]    The present invention relates to a method for operative physical cooperation between a mobile phone or PDA and an associated peripheral device, and improved methods for both physically combining the above and for electronically connecting the same. 
       2. DISCUSSION OF THE RELATED ART 
       [0003]    Recently, mobile terminal such as mobile phones, smart phones and/or PDAs are becoming widely used as more than mere communication or media devices. There are a variety of applications for such mobile terminals that strive to amplify the abilities of such terminals for additional purposes that may be achieved through the use of special purpose peripherals that can be connected thereto. 
         [0004]    However, when the mobile terminal 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 given 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. 
         [0005]    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. Moreover, certain peripheral devices such as handheld barcode scanning devices and Magnetic Strip Readers (MSRs) currently are not easily associated or connected with mobile terminals such as mobile telephonic devices. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention relates to a mobile device and peripheral device consolidation system 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 terminal to be readily and conveniently paired with a peripheral device, including bar code readers and MSRs that substantially obviates one or more problems due to limitations and disadvantages of the related art. 
         [0007]    The proposed invention therefore relates to a novel approach to augmenting the use of PDAs, mobile phones and smart phones with peripheral add-on devices such as compact bar code scanners and magnetic strip readers (MSRs) and virtually any other manner of compact peripheral device. When a peripheral device (such as the illustrative handheld barcode scanning device and/or MSR) needs to be used and with a PDA, mobile phone or smart phone, the present invention thusly provides a physical and electronic platform or “sled” that can physically attach any of the aforementioned to each other in a convenient, modular fashion. In doing so, the present inventive approach utilizes a plastic housing that can house a handheld barcode scanning device and/or a MSR in a streamlined, consolidated fashion for ready attachment to the back of a mobile device, with an electronic communication being afforded 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. 
         [0008]    Furthermore, in one optional instantiation, provision of such means that a user can easily employ a hands-free trigger connected to the handheld barcode scanning device or other apparatus while the same is currently connected via a Bluetooth®-protocol based connection to the other aforementioned devices. The inventive approach is therefore especially valuable in that permits usage of mobile phones, smart phones and PDAs with a handheld barcode scanning device, a MSR, or other peripheral apparatus in a wireless, physically compact and consolidated fashion that requires little or no set up and integration, and which can furthermore be employed in a hands-free mode, if required. 
         [0009]    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 device and a peripheral device through: (1) provision of a “sled” that comprises a physical smart phone/cell phone cover that can provide for convenient, durable physical attachment between the same and peripheral devices; (2) provision of optional side scan button utilizing a hands free trigger technology; (3) provision of said sled with physical capacity for insertion of optional peripheral device such as a compact bar code reader and/or a MSR; (4) inherent modularity for connection of each of the above-referenced devices, whereby the sled may be used to connect the peripheral device (bar code reader and/or MSR, etc.) with the smart phone/cell phone via a wireless connection such as a Bluetooth®-type connection, without the need for use of a physical electronic connector (cable); (5) enabling a user, through the inventive architecture, to change smart phones/cell phones (as well as peripherals such as the compact bar code reader and/or MSR) periodically, without replacing the inventive sled; (6) provision of a supplemental battery pack within the sled that allows a user to charge the smart phone/cell phone using a sled battery pack contained within the sled; (7) provision of a wireless port, such as an illustrative dual Bluetooth® port which offers a first port which can wirelessly connect the sled with the smart phone/cell phone, and a second port which can wirelessly connect the sled and other Bluetooth® devices, such as Bluetooth® based printer. 
         [0010]    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 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. 
         [0011]    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. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

This version, which is intended to be used within the meaning of attachment means  20  as a custom engagement structure, rather than as part of a native mobile device casement engagement structure, includes integral lateral rails  234  which slidingly engage and lock or otherwise frictionally secure a mobile device (not pictured) laterally along the length of integrated sled  225 . It should be noted that, although integrated sled  225  is depicted as including both a barcode and MSR, integral lateral rails  234  are intended to be within the meaning of attachment means  20  for use with other peripheral devices by themselves (e.g., with just a compact barcode scanner, with just an MSR, with just an IC reader, just at least one of the biometric verification modules, just at least one of the multi-threat monitors or other peripheral devices), or in conjunction with each other. In any case, as seen this device may feature aspects such as the illustrative barcode scan engine (1D laser or 2D imager)  220 , trigger button  221 , 233 , Up/Down (scroll) button  222 , 8-pin micro USB connector for both sled and mobile device charging  223 , MSR module  224 ,  230 , power switch  231 , and status LED  232 . 
         [0043]      FIG. 7E  depicts an schematic view of a variant of an illustrative attachment accomplished via a universal engagement structure for attachment of a peripheral device to a mobile device, which is also intended to be used within the meaning of attachment means  20 .

As can be appreciate, this variant engagement structure of the sled allows for virtually any type of mobile device to be readily combined with almost any manner of peripheral device in a secure physical fashion. 
         [0044]      FIG. 8  illustrates an example of a block diagram representing portions of the overall of the connectivity of the various inventive aspects that can be implemented with peripheral devices such as an illustrative compact bar code scanner, MSR with MSR controller and a charging base according to one embodiment of the present invention. As seen therein, the sled may be comprised, among other things, of Barcode Base board  300  which may offer features such as status LEDs, scan, scroll and power buttons, as well as different types of USB and micro USB ports, as depicted therein for operational control and connectivity with other components of the overall system. Barcode base/MSR base/Charging base connector  301  will connect, in one embodiment, MSR Base  310  and Charging Base  320  with Barcode Base  300 . To that end, MSR Base  310  may include features such as an MSR Header Controller, MSR module, and pin connectors. An MSR controller board  330  for an MSR independent system may be connected via a special pin connector at  302  to MSR Base  310 . Similarly, Charging Base  320 , which may include features such as a power switch, status LEDs, a 7 pin dip switch and a micro USB connector is connected via Barcode base/MSR base/Charging base connector  301  to Barcode Base board  300  and/or MSR Base  310 . Note that where Charging Base  320  is provided as an optional peripheral device, it can also be used to charge mobile device  11 . 
         [0045]    As it pertains to the provision of the charging base as peripheral aspect of the inventive sled, circuitry may be provided for both the charging of a peripheral such as the compact barcode reader, again illustratively shown as the KDC®400 or a KDC®400-type unit as well as for the charging of the mobile device itself. In describing this circuitry, reference will also be made for use of the optional peripheral device trigger therein. Specifically, one USB port (e.g., an 8-pin micro USB, as depicted in  FIG. 9 ) may be provided for the above uses wherein: (i) GND and USB_VBUS pins are utilized to charge the KDC®400 or a KDC®400-type unit; (ii) the USB_DP and USB_DM signals are used to communication with another USB device, such as the mobile device (or another peripheral device); (iii) use is made of FINGER_TRIGGER# and GND signals to allow external trigger mechanism such as the peripheral trigger and/or trigger gun handle; (iv) use is made of GND, USB_VBUS_EXT, USB_DM_EXT, USB_DP_EXT signals to charge the mobile device. Thereafter, a custom cable may be developed in accordance with the above in order to connect 8-pin USB connector on the KDC®400 or a KDC®400-type unit with the mobile device (or another peripheral device). Provision of the above charging circuitry within the illustrative the KDC®400 eliminates the need for use of multiple USB ports for charging. The signal schematic grid for the above signals and operative charging elements (e.g. as achieved through the 8-pin micro USB PIN assignment arrangement discussed above) may be depicted by virtue of the below chart:

         [0046]    When provided as described herein, the inventive system will support various charging logic, including but not limited to, the standard USB charging and mobile device-specific charging logic such as that found in iPhone® specific charging logic. In doing so, any exemplary compact barcode reader-type peripheral, such as the aforementioned KDC400 type unit can select the matching charging logic depending on a specific user selection, which can be selecting by provision of: (i) an internal DIP Switch (as shown in  FIG. 8  and elsewhere herein); (ii) a mobile device configuration utility; and/or (iii) scanning of a special barcode, if integrated with the described barcode base  300 . These choices can also be illustratively implemented as a separate menu in the exemplary KDC®400 or a KDC®400-type unit can automatically select the charging logic depends on the exact user selection of the specific Bluetooth® profile, thereby supporting proprietary mobile device circuitry, such as an iPhone®-specific charging circuit if a given user selects an iPhone® Bluetooth connection method. 
         [0047]    As previously mentioned, peripheral device  10  of the modular sled 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, or RF ID tag readers. In one alternative embodiment, peripheral device  10  of the modular sled may be of any type of at least one of the following peripheral devices comprising: biometric verification modules or multi-threat monitors. Specifically, portable, wireless biometric verification modules, when employed as peripheral devices, may include at least one of the following of iris readers, fingerprint readers, facial recognition readers, and the like, although other possible embodiments related thereto may be included herein. One such illustrative portable, wireless device might be something akin to the HIIDE™ device, available from L-1 Identity Solutions of Billerica, Mass., or the like as may be known. As for multi-threat monitors, such monitors may include gas detection monitors, radiation monitors, man-down monitors, volatile organic compound monitors, and the like, each having integrated wireless functionality. Non-limiting, illustrative examples of such devices might include: MultiRAE™ portable multi-threat monitors, available commercially from RAE systems of San Jose, Calif.; Instadose™ dosimeters available from Global Dosimetry of Irvine, Calif. One other alternative monitor intended to be included within the aforementioned multi-threat monitors grouping may include available technology currently known as Citizen&#39;s Dosimeter (the details of which are disclosed in U.S. Pat. No. 7,781,747 to Klemic, Issued Aug. 24, 2010, the entirety of which is hereby incorporated by reference herein), available from the U.S. Department of Homeland Security, which is a radiation-sensitive material similar to a credit card in size, which could be read with a card reader such as a StorCard® reader available from StorCard, Inc. of Carmel, Calif. 
         [0048]    Similarly, mobile device  11  may be of the type chosen from the groups comprising mobile phones, smart phones, PDAs, etc. and will generally include a display for implementing interactivity with a user. Such displays often have a “soft keyboard” that is frequently used by a user in order to input data. By way of just one illustration, the example utilized herein will be a compact bar code scanner that has a configurable key for controlling the soft keyboard of the mobile device, such as that found in the illustrative KDC® 400 type unit, available from KoamTac® Inc., of Princeton, N.J., and includes a relatively smaller display for interactivity with a user, and may provide the user with different menu screens for the various functions described herein. Other menu images can be implemented on the display as necessary, and provision is also made for the configurable key therein to control mobile devices without soft keyboards. Similarly, multifunction keys, such as those found in the KDC® 400 can also be provided for various operations, including but not limited to: power ON/OFF buttons, scan buttons on both sides, and up/down (scroll) control buttons. 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 scanning unit with programming capability, or the ability to function with KTSync® type software downloaded therein, in order to provide the configuration options on any configurable keys (e.g., toggle key, menu, etc.). Accordingly, provision can be made for auto reconnection and toggling, a feature that is most useful in cases where it is found that a Bluetooth® connected device can often be abnormally disconnected due to unexpected noise in the 2.4G range Bluetooth® spectrum or for other reasons known in the art of wireless connectivity. In accordance with the above, the illustrative KDC®400 can be reconnected to the host computer automatically by pressing the side up button, while the down button can be defined as Bluetooth® disconnection key or soft keyboard toggling key when in HID mode. 
         [0049]    As it relates to provision of Bluetooth® profile selection, in cases where the illustrative KDC® 400 is employed as, say, a compact barcode reader within the overall inventive modular sled system, it is worth noting that three different Bluetooth® connection modes can be supported, depending on the mobile device that is desired to be connected thereto. An SPP mode may be used to connect host devices supporting SPP or RFCOMM profiles such as Android®, Blackberry® and Microsoft Windows® that may be found on various mobile devices. As those skilled in the art will appreciate, RFCOMM profiles offer a socket-based client-server paradigm for providing services, and are typically employed where a user desires to create a client-server based application using Bluetooth®. Similarly, a Serial Port Profile (SPP) defines the requirements for Bluetooth® devices that are necessary for setting up emulated serial cable connections using RFCOMM between two peer devices, and are requirements that are expressed both in terms of services provided to applications, and by defining the features and procedures that are required for interoperability between Bluetooth® devices. Essentially, the Serial Port Profile defines the protocols and procedures that shall be used by devices using Bluetooth® for RS232 (or similar) serial cable emulation, and can even be employed with legacy applications that are using Bluetooth as a cable replacement through a virtual serial port abstraction. In one specific example, a proprietary mobile device such as an iPhone® will use an iPhone® mode to connect to iOS® devices such as iPhone®, iPad® and iPod® touch. In a separate example, an HID mode can be used to connect a host device that supports HID profiles. In any case, these various Bluetooth profiles can be configured from a native mobile device configuration utility or through the use of scanning of special barcodes. 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. Alternatively, a unit such as an illustrative KDC® 200 or KDC® 300 type unit (also available from KoamTac® Inc., of Princeton, N.J.) already has specialized built in Bluetooth® management software (such as that found in KTSync®), may also be utilized. 
         [0050]    As it relates to provision of Bluetooth® pairing and connection procedures, in cases where the illustrative KDC® 400 is employed as a compact barcode reader within the overall inventive modular sled system, the several different approaches are supported. Specifically: (i) a user can set up the illustrative KDC® 400 to enter pairing mode automatically upon powering on; (ii) a user can set up the illustrative KDC® 400 to enter pairing mode upon powering on and by pressing certain combination of KDC® 400 buttons; (iii) the illustrative KDC® 400 can be programmed to exit the pairing and connection mode if a pairing and connection status is successfully achieved, or if otherwise timed out; and/or (iv) a user also can abort the pairing and connection procedure by simply pressing certain combination of KDC® 400 buttons. It is noted, in accordance with the disclosure elsewhere herein, a dual (Bluetooth®) port can be provided for the above-referenced connectivity aspects, with a first port connecting the sled and the mobile device, and a second port connecting the sled and other peripheral Bluetooth® devices described herein, as well as physically separate peripheral devices such as Bluetooth® connected printers and the like. 
         [0051]    Within the aforementioned schemes, specific additional features may further be utilized according to the present invention within the sled as a feature of a peripheral such as the illustrative KDC®400. For example, status LEDs (of different colors), vibrators, or beepers/buzzers may be provided in order to let users know operational statuses such as: (i) scan success or failure; (ii) Bluetooth® pairing and connection; (iii) Bluetooth® profile; and/or (iv) battery charging or low battery. Although not meant to be limiting in any way as it pertains to the disclosure and coverage of the invention, one might employ the following status signifiers shown in the table below for possible KDC®400 (or other peripheral device) settings in the modular sled:
