DETAILED DESCRIPTION
[0016] As utilized herein the terms "circuits" and "circuitry" refer to physical electronic components (i.e. hardware) and any software and/or firmware ("code") which may configure the hardware, be executed by the hardware, and or otherwise be associated with the hardware. As utilized herein, "and/or" means any one or more of the items in the list joined by "and/or". As an example, "x and/or y" means any element of the three- element set {(x), (y), (x, y)}. As another example, "x, y, and/or z" means any element of the seven-element set {(x), (y), (z), (x, y), (x, z), (y, z), (x, y, z)}. As utilized herein, the terms "block" and "module" refer to functions than can be performed by one or more circuits. As utilized herein, the term "example" means serving as a non-limiting example, instance, or illustration. As utilized herein, the term "e.g.," introduces a list of one or more non-limiting examples, instances, or illustrations.
[0017] FIG. 1 depicts an example protective case with integrated wireless adaptor for a handheld electronic device. Referring to FIG. 1, the example case 100 comprises walls 102a-102e to encase a handheld device. The walls 102a-102d of this example implementation are arranged such that a handheld device mounts to the case 100 by sliding in from the top (as indicated by arrow 120) and, once the handheld is mounted, the arrange may be as follows: an inner surface of wall 102a faces a front side (e.g., screen and/or bezel) of the handheld device; an inner surface of the wall 102b faces a right side of the handheld device; an inner surface of the wall 102c faces a left side of the handheld device; an inner surface of the wall 102d faces a back side of the handheld device; and an inner surface of the wall 102e faces the bottom of the handheld device.
Thus, the example case 100 substantially encases the mounted handheld device such that: the device is secured in the case 100 and does not inadvertently fall out of the case 100, the device is protected from scratches, and/or the handheld device is protected from damage in the event that it is dropped. The dimensions of the handheld device plus case
100 when the device is mounted may be substantially similar to the dimensions of the handheld device when it is not mounted in the case 100. For example, each of the walls 102a-102d may be on the order of millimeters in thickness and the wall 102e may be on the order of tens of millimeters in thickness.
[0018] In the example case 100, the walls 102a-102e may be made of rubber or plastic (or other suitable material). The wall 102a has a cut-out to allow access to a touchscreen of the mounted handheld device. The wall 102d has an antenna 110 embedded in it. The wall 102e has cutouts 104a and 104b to enable access to features (e.g., speakers) of the handheld device, has a cutout 104c to enable connection (e.g., via a USB cable) to a device (e.g., a laptop or desktop computer) that is not mounted in the case 100, and has a module 112 embedded in it (and is thus thicker than walls 102a-102d to accommodate the module 112).
[0019] FIG. 2 depicts an example module of the case shown in FIG. 1. The example module 112 may function as a wireless adaptor and comprises a CPU 212, memory 214, input/output (I/O) module 216, radio module 218, connector 220, and connector 222.
[0020] The CPU 212 may be operable to control operation of the wireless case 100. The CPU 212 may, for example, execute an operating system, and/or other programs (e.g., programs that implement one or more layers of a network protocol stack) to, for example, process data, manage transfers of data, and/or control operation of the various modules of the case 100.
[0021] The memory module 214 may comprise, for example, RAM, configuration registers, and/or mass storage (e.g., a hard drive and/or flash memory). The memory module 210 may comprise program memory that may store code to be executed by the
CPU 212, run-time data that may be generated as a result of the CPU 212 executing code, parameters which configure one or more of the modules of the case 100, and/or data received via the busses 224a and 224b. The case 100 may support a mode of operation in which a device to which the case 100 is mounted can use memory 214 as a mass storage device (e.g., a USB mass storage device).
[0022] The I/O module 216 may be operable to manage or facilitate transfers over and/or among data busses 226, 224a and 224b. In an example implementation, I/O module 216 may perform packet-based switching or routing among data busses 226, 224, and 224b. In an example implementation, protocols used on the busses 226, 224a, and 224b may comprise, for example, one or more of USB, IEEE 1394, Ethernet, PCMCIA, PCI-X, and/or any other suitable protocol(s). In an example implementation, the I/O module 216 may operate as a passthrough such that the connector 222 is (or appears to devices connected to connector 222 and connector 220 as if it is) directly connected (i.e. "wired") to the connector 220. In an example implementation, the I/O module 216 may operate a selective passthrough such that sometimes, and/or for some devices, the connector 220 and connector 222 are (or appear to be) wired together and sometimes, and/or for some devices, are not (or appear not to be) wired together.
[0023] For transmission, the radio 218 may be operable to receive data via the bus 226, packetize the data, encode the data, convert the data to analog, modulate the data onto one or more carriers, and/or otherwise process the data to prepare it for transmission via antenna 110 in accordance with one or more wireless protocols. For reception, the radio 218 may be operable to receive data RF signals via antenna 110, downconvert, demodulate, decode, convert to digital, and/or otherwise process the received signals to recover data contained therein, and make the data available to the bus 226. In an example implementation, the radio 218 may support one or more wireless communication protocols not supported by a handheld device with which the case 100 is designed to interface. Example wireless communication protocols which may be supported by the radio 218 include the ISO 18000-7 standard, and protocols described in United States patent applications having serial numbers 13/267,640 ("Method and Apparatus for Adaptive Searching of Distributed Datasets") and 13/267,621 ("Method and Apparatus for Low-Power, Long-Range Networking"), which are incorporated herein by reference as set forth above.
[0024] The antenna 110 may be operable to transmit and receive electromagnetic signals in one or more frequency bands. In an embodiment of the invention, the antenna 110 may be operable to transmit and receive signals in the ISM frequency band centered at 433.92 MHz.
[0025] The connector 220 may enable electrical connection of the case 100 to a handheld electronic device 300 mounted in the case 100. The connector 220 may comprise pins suitable for carrying the protocol(s) utilized on the bus 224a. In an example implementation, the connector 220 may be a male connector.
[0026] The connector 222 may enable electrical connection of an electronic device (e.g., a computer) to the case 100 while a handheld device is mounted in the case 100 and/or to the handheld electronic device mounted in the case 100. The connector 222 may comprise pins suitable for carrying the protocol(s) utilized on the bus 224b which may comprise, for example, USB, IEEE 1394, Ethernet, and/or any other suitable protocol. In an example implementation, the connector 222 may be a female connector.
[0027] FIG. 3 depicts an example handheld electronic device that is operable to interface with the case with integrated wireless adaptor described with reference to FIGS. 1 and 2. The example device 300 comprises a CPU 312, a memory 304, an I/O module 306, a radio 308, and a connector 310. The handheld device 300 may be, for example, a tablet computer or smartphone.
[0028] The CPU 302 may be operable to control operation of the handheld wireless device 300. The CPU 302 may, for example, execute an operating system, and/or other programs (e.g., programs that implement one or more layers of a network protocol stack) to, for example, process data, manage transfers of data, and/or control operation of the various modules of the handheld device 300.
[0029] The memory module 304 may comprise, for example, RAM, configuration registers, and/or mass storage (e.g., a hard drive and/or flash memory). The memory module 304 may be comprise program memory that may store code to be executed by the CPU 302, run-time data that may be generated as a result of the CPU 212 executing code, parameters which configure one or more of the modules of the case 100, and/or data received via the bus 312.
[0030] The I/O module 306 may be operable to manage or facilitate transfers over and/or between data busses 312 and 314. In an example implementation, protocols used on the busses 314 and 314 may comprise, for example, one or more of USB, IEEE 1394, Ethernet, PCMCIA, PCI-X, and/or any other suitable protocol(s).
[0031] For transmission, the radio 308 may be operable to receive data via the bus 226, packetize the data, encode the data, convert the data to analog, modulate the data onto one or more carriers, and/or otherwise process the data to prepare it for transmission via antenna 316 in accordance with one or more wireless protocols. For reception, the radio 308 may be operable to receive data RF signals via antenna 316, downconvert, demodulate, decode, convert to digital, and/or otherwise process the received signals to recover data contained therein, and make the data available to the bus 314. In an example implementation, the radio 308 may support, cellular protocols, Wi-Fi, WiMAX, Bluetooth, and/or other wireless communication protocols but may not support one or more wireless communication protocols supported by the case 100. Example wireless communication protocols which may be supported by the radio 218 include the ISO 18000-7 standard, and protocols described in United States patent applications having serial numbers 13/267,640 ("Method and Apparatus for Adaptive Searching of Distributed Datasets") and 13/267,621 ("Method and Apparatus for Low-Power, Long- Range Networking"), which are incorporated by reference above.
[0032] The antenna 316 may be operable to transmit and receive electromagnetic signals in one or more frequency bands. In an embodiment of the invention, the antenna 316 may be operable to transmit and receive signals in frequency bands utilized by cellular, Wi-Fi, and/or Bluetooth protocols.
[0033] The connector 310 may enable electrical connection of the handheld device 300 to other devices. The connector 310 may comprise pins suitable for carrying the protocol(s) utilized on the bus 312. In an example implementation, the connector 310 may be a female connector.
[0034] FIG. 4 is a flowchart illustrating communication by a system comprising a smartphone and a protective case with integrated wireless adaptor. The example steps begin with step 402 in which the case 100 is mounted to the handheld device 300. In step 404, information is exchanged, via bus 224a, connector 220, connector 310, and bus 312, between the case 100 and the device 300 to establish a connection between the device 300 and case 100. In step 406, the device 300 generates data to be transmitted and outputs the data to the connector 300. In step 408, the case 100 receives, via connector 220, the data generated in step 406. In step 410, the case 100 processes the data (e.g., based on commands received along with the data) and transmits the data via the radio.
[0035] In step 412, the case may receive data via the radio 218. The data may be, for example, a response to the data transmitted in step 410. In this regard, the communications via the radio 218 may be part of an adaptive search as described in
Unites States Patent Application serial number 13/267,640, which is incorporated by reference above. In step 414, the case 100 may output the data to the connector 220. In step 416, the device 300 may receive the received data via connector 310. In step 418, the device 300 may process the data and present it, and/or related information to a user. [0036] FIG. 5 is a flowchart illustrating messaging operations performed by a system comprising a smartphone and a protective case with integrated wireless adaptor. The example steps begin with step 502 in which the case 100 is mounted to the handheld device 300. In step 504, information is exchanged, via bus 224a, connector 220, connector 310, and bus 312, between the case 100 and the device 300 to establish a connection between the device 300 and case 100. In step 506, a user of the device 300 launches a messaging application, creates a message to be sent to a another device (e.g., a device like the device 300 that is mounted to a case like the case 100) which may be reachable via some unique identifier (e.g., phone number, voice mail, IP address, etc.), and clicks "send." In step 508, the device 300 informs the case 100 of the message to be sent and the case 100 determines whether the other device can be reached via the radio 218. If so, then in step 512 the message is transmitted via the radio 218. If not, then in step 510 the message is transmitted via radio 308. In an example implementation, the message may be an SMS (short messaging service) or MMS (multimedia messaging service) message. Accordingly, when the other device is in range of the radio 218 the SMS or MMS message may be converted to a format suitable for the radio 218 and transmitted via the radio 218 rather than via a cellular transmitter of the device 300. In an example implementation, the radio 218 may be lower power and/or lower cost. Sending the message via the radio 218 may be lower cost because, for example, the frequencies over which the radio 218 communicates may not require a license in the location in which the message is being transmitted, and or the license required is less expensive than the cost to send an MMS or SMS message via a cellular carrier associated with the radio 308.
[0037] FIG. 6 is a flowchart illustrating social network operations performed by a system comprising a smartphone and a protective case with integrated wireless adaptor. The example steps begin with step 602 in which the case 100 is mounted to the handheld device 300. In step 604, information is exchanged, via bus 224a, connectors 220, connector 310, and bus 312, between the case 100 and the device 300 to establish a connection between the device 300 and case 100. In step 606, a user configures (e.g., via a graphical user interface (GUI) running on the device 300) profile information (e.g., the user's "likes" and "dislikes," the user's affiliations, products the user is using/carrying/wearing, the user's online URLs/handles/identifiers, etc.) that the user wishes to share with other that are in-range of the radio 218. In step 608, the device 300 may store the profile information to the memory 214 and the profile information may then be broadcast (e.g., periodically) via the radio 218.
[0038] FIG. 7 is a flowchart illustrating connection initialization operations performed by a system comprising a smartphone and a protective case with integrated wireless adaptor. The example steps begin with step 702 in which the case 100 is mounted to the handheld device 300. In describing the steps of FIG. 7, it is assumed that the radio 308 supports a first wireless protocol such as, for example, Bluetooth, which has a shorter range than the second wireless protocol(s) supported by the radio 218.
[0039] In step 704, information is exchanged, via bus 224a, connectors 220, connector 310, and bus 312, between the case 100 and the device 300 to establish a connection between the device 300 and case 100. In step 706, the case 100 determines (e.g., via transmission and/or reception of beacons, probes, and/or other messages via the radio 218) that the it and the device 300 mounted to it are approaching a another device which has one or more radios that support the first wireless protocol (e.g., Bluetooth) and the second wireless protocol (e.g., protocols described in United States patent applications having serial numbers 13/267,640 ("Method and Apparatus for Adaptive Searching of Distributed Datasets") and 13/267,621 ("Method and Apparatus for Low- Power, Long-Range Networking"), which are incorporated herein by reference as set forth above. [0040] In step 708, the case 100 communicates with the other device via the radio 218 to exchange information for setting up a connection between the radio 308 and the second device, in anticipation of the other device coming within range of the radio 308. In step 710, the other device becomes in-range of the radio 308 and the information exchanged in step 708 is utilized to quickly establish a connection between the radio 308 and the other device. In this manner, the radio 218 enables out-of-band setup (or at least partial setup) of a network connection between the radio 308 and the other device while the other device is out-of-range of the radio 308.
[0041] FIG. 8 is a flowchart illustrating determining location in a system comprising a smartphone and a protective case with integrated wireless adaptor. The example steps begin with step 802 in which the case 100 is mounted to the handheld device 300. In step 804, information is exchanged, via bus 224a, connector 220, connector 310, and bus 312, between the case 100 and the device 300 to establish a connection between the device 300 and case 100. In step 806, the device 300 requests location information from the case 100. In step 808, the case 100 searches for tags (e.g., ISO 18000-7 compliant tags) and/or other devices which are in range of the radio 218. The search may, for example, be performed as described in United States patent application serial number 13/267,640 ("Method and Apparatus for Adaptive Searching of Distributed Datasets"), which is incorporated herein by reference as set forth above. In step 810, the case 100 may determine its location based on responses received in step 808. For example, the case 100 may triangulate is location based on the number of responses received, the identity of devices or tags from which responses were received, and/or the timing with which the responses were received. The determination of location may comprise consulting a local and/or remote database which stores the location of tags and/or devices. In step 812 the case 100 may convey the determined location to the device 300. [0042] Other implementations may provide a non-transitory computer readable medium and/or storage medium, and/or a non-transitory machine readable medium and/or storage medium, having stored thereon, a machine code and/or a computer program having at least one code section executable by a machine and/or a computer, thereby causing the machine and/or computer to perform the steps as described herein for using a device case with integrated wireless adaptor.
[0043] Accordingly, the present method and/or apparatus may be realized in hardware, software, or a combination of hardware and software. The present method and/or apparatus may be realized in a centralized fashion in at least one computing system, or in a distributed fashion where different elements are spread across several interconnected computing systems.
