The one or more computer processors 104/124 may include, without limitation: a central processing unit (CPU), a digital signal processor (DSP), a reduced instruction set computer (RISC), a complex instruction set computer (CISC), a microprocessor, a microcontroller, a field programmable gate array (FPGA), or any combination thereof. The user devices 102 may also include a chipset (not shown) for controlling communications between the one or more processors 104/124 and one or more of the other components of the user device 102. In certain embodiments, the user device 102 may be based on an Intel® architecture or an ARM® architecture, and the processor(s) and chipset may be from a family of Intel® processors and chipsets. The one or more processors 104 may also include one or more application-specific integrated circuits (ASICs) or application-specific standard products (ASSPs) for handling specific data processing functions or tasks.
The memory 106/126 may comprise one or more computer-readable storage media (CRSM). In some embodiments, the memory 106/126 may include non-transitory media such as random access memory (RAM), flash RAM, magnetic media, optical media, solid-state media, and so forth. The memory 106 may be volatile (in that information is retained while providing power) or non-volatile (in that information is retained without providing power). Additional embodiments may also be provided as a computer program product including a transitory machine-readable signal (in compressed or uncompressed form). Examples of machine-readable signals include, but are not limited to, signals carried by the Internet or other networks. For example, distribution of software via the Internet may include a transitory machine-readable signal. Additionally, the memory 106/126 may store an operating system that includes a plurality of computer-executable instructions that may be implemented by the computer processor 104/124 to perform a variety of tasks to operate the interface(s) and any other hardware installed on the user device 102. The memory 106/126 may also store content that may be displayed by the user device 102 or transferred to other devices (e.g., headphones) to be displayed or played by the other devices. The memory 106/126 may also store content received from the other devices. The content from the other devices may be displayed, played, or used by the user device 102 to perform any necessary tasks or operations that may be implemented by the computer processor 104/124 or other components in the user device 102 and/or base station 122.
The network and I/O interfaces 114/134 may also comprise one or more communication interfaces or network interface devices to provide for the transfer of data between the user device 102 and another device (e.g., network server) via a network (not shown). The communication interfaces may include, but are not limited to: personal area networks (PANs), wired local area networks (LANs), wireless local area networks (WLANs), wireless wide area networks (WWANs), and so forth. The user device 102 may be coupled to the network via a wired connection. However, the wireless system interfaces may include the hardware and software to broadcast and receive messages either using the Wi-Fi Direct Standard (see Wi-Fi Direct specification published in October 2010) and/or the IEEE 802.11 wireless standard (see IEEE 802.11-2012, published Mar. 29, 2012), the Bluetooth standard, or any other wireless standard and/or a combination thereof. The wireless system (not shown) may include a transmitter and a receiver or a transceiver capable of operating in a broad range of operating frequencies governed by the IEEE 802.11 wireless standards. The communication interfaces may utilize acoustic, radio frequency, optical, or other signals to exchange data between the user device 102 and another device such as an access point, a host computer, a server, a router, a reader device, and the like. The network 120 may include, but is not limited to: the Internet, a private network, a virtual private network, a wireless wide area network, a local area network, a metropolitan area network, a telephone network, and so forth.
The display 116/134 may include, but is not limited to, a liquid crystal display, a light-emitting diode display, or an E-Ink™ display as made by E Ink Corp. of Cambridge, Mass. The display may be used to show content to a user in the form of text, images, or video. In certain instances, the display may also operate as a touch screen display that may enable the user to initiate commands or operations by touching the screen using certain finger or hand gestures.
Broadly, a radio connection between a user device 102 and a base station 122 may be automatically established upon the user device 102 entering within a certain proximity of the base station 122. For example, the proximity reader 130 included in the base station 122 may be configured to emit a magnetic field. In certain embodiments, the magnetic field may be emitted in an approximately spherical shape around the base station 122. Furthermore, the range of the magnetic field may be a radius of approximately 1.5 meters to 2 meters. To this end, the proximity transponder 112 in the user device 102 may be configured to receive and/or detect the magnetic field when the user device 102 (or the proximity transponder 112) enters within range of the magnetic field. Upon detecting and/or otherwise determining the magnetic field, the proximity transponder 112 may be configured to transmit, to the base station 122 (e.g., the proximity reader 130), identification information associated with the user device 102.
For instance,
In certain embodiments, as a result of being energized by the magnetic field, one or more of the inductive coils 204/206/208 may provide power to the proximity transponder 112. The proximity may then use the power to transmit identification information associated with the user device 102 to the base station 122. In this manner, identification information may be transmitted to the base station 122 without requiring any power on the part of the user device 102. For instance, the user device 102 may be a mobile phone having a battery (not illustrated), and the base station may be a wireless display device. To this end, the mobile phone may be configured to transmit identification information, via the proximity transponder 112, without draining and/or otherwise using the power from the battery. Instead, the proximity transponder 112 may be energized and/or powered (e.g., via its inductive coils 204/206/208) upon entering the 3D magnetic filed emitted by the proximity reader 130 of the base station 122. It will be appreciated that while
Referring back now to
In some implementations, upon receiving the identification information from the user device (e.g., from the proximity transponder 112), the base station 122 may determine whether the identification information is valid. For instance, the base station 122 may determine whether the identification information matches one or more identifiers and/or credential information. Such information may be stored in memory 126, a database (not pictured), and/or any other storage location both local and/or remote to the base station 122. If the base station 122 determines that the identification information is valid, the base station 122 may transmit a verification of the identification information back to the user device 102. On other hand, if the base station 122 determines that the identification information is invalid, then the base station 122 may notify the user device 102 of the invalidity.
According to one or more embodiments, the proximity transponder 112 may be configured to perform additional operations upon detecting and/or receiving the magnetic field from the base station 122 (e.g., emitted by the proximity reader 130). For example, the proximity transponder 112 may transmit radio communication information to the proximity reader 130 of the base station 122. The radio communication information may include any type of data that facilitates the establishment of a radio connection between the user device 102 and the base station 122. For example, the radio communication information may include a network address identifier (e.g., a media access control (MAC) address), a pairing key, and/or the like associated with the radio transceiver 110 of the user device 102. In certain implementations, the radio communication information may be stored on the user device 102, such as in memory 106. Alternatively, the radio communication information may be stored in any storage location, both local and/or remote to the user device 102. Upon receiving the radio communication information from the proximity transponder 112, the proximity reader 130 may provide the radio communication information to the base station radio transceiver 128 of the base station 122.
According to certain embodiments, base station radio transceiver 128 may establish, based at least in part on the received radio communication information, a radio connection with the radio transceiver 110 of the user device 102. For instance, as discussed above, the radio communication information may include a MAC address and/or pairing key associated with the radio transceiver 110. To this end, the base station radio transceiver 128 may pair and/or otherwise connect with the radio transceiver 110 of the user device 102 using the MAC address and/or pairing key. In some implementations, a communication application 108 in the user device 102 may be used to facilitate the establishment of the radio connection with the base station 122 as well as facilitate further communication with the base station 122 once the radio connection has been created.
In certain embodiments, upon establishing a radio connection between the base station radio transceiver 128 and the radio transceiver 110, the base station 122 may instruct the proximity reader 130 to cease emitting the magnetic field. Furthermore, if the base station 122 determines that the radio connection with the user device 122 has been broken, lost, and/or otherwise disconnected, the base station 122 may instruct the proximity reader 130 to begin emitting the magnetic field once again.
It will be appreciated that numerous types of radio connections may be established between the user device 102 and the base station 122. For example, the base station 122 may include and/or may be coupled to a wireless display device, and the radio connection may include a streaming wireless display connection. To this end, the base station radio transceiver 128 may be configured to transmit wireless display connection information to the radio transceiver 110 of the user device 102. The wireless display connection information may include any type data that may facilitate a streaming wireless display connection between the user device 102 and the base station 122. For instance, the wireless display connection information may include a wireless display identifier and/or a personal identification number (PIN) associated with the base station 122. Upon receipt of the wireless display connection by the radio transceiver 110, a streaming wireless display connection may be established between the user device 102 and the base station 122.
As another example, the radio connection may include a wireless gigabit radio connection (e.g., a WiGig connection) for transmitting data between the user device 102 and the base station 122. In yet other implementations, the radio connection may include “check-in” type communication, in which the base station 122 may determine the presence of a particular user upon the user device 102 entering the magnetic field (e.g., boarding an airplane, ticketing for a sports event or other event, etc.). In some implementations, the radio connection may include a media streaming connection between the user device and a vehicle infotainment system. As such, the radio connection may facilitate communicating various types of information such as direction routing information, video data, audio data, and/or the like.
Moreover, it will be appreciated that the proximity transponder 112 and the proximity reader 130 described herein may include radio frequency identification (RFID) technology. For example, the proximity transponder 112 may be an RFID tag (e.g., a passive tag, though active tags are also contemplated), and the proximity reader 130 may be an RFID reader. Additionally, in certain implementations, the proximity transponder 112 and the proximity reader 130 may communicate in a relatively low frequency band, such as an approximate range of 120 KHz to 150 KHz, although other ranges are also possible. In other implementations, the proximity transponder 112 and/or the proximity reader 130 may utilize other wireless communication technology (e.g., Bluetooth, Bluetooth Low-Energy, Wi-Fi, Long Term Evolution, Long Term Evolution-Advanced, and/or the like).

In block 330, the user device 102 may be receive, from the base station 122, a verification of the identification information. The verification may indicate that the base station 122 determined the identification information to be valid. In block 340, the user device 102 may establish, by the radio transceiver 110 based at least in part on the verification, a radio connection with the base station 122.
Referring now to
In block 430, the base station 122 may be configured to determine whether the identification information is valid (e.g., in order to verify whether a radio connection may be established). To this end, in block 440, the base station 122 may be configured to establish, by the radio transceiver 128 upon determination that the identification information is valid, a radio connection with the user device 102.
