    摘要: A wearable mobile computer communicates with a headset worn by an operator using a communication channel established between the computer and a radio frequency identification (“RFID”) tag located in the headset. The headset may be configured for receive only (voice travels only from the computer to the headset) or configured for two-way voice communication. For two-way communication backscatter from the RFID tag is used to carry voice signals.

    摘要: An RFID portal is enhanced to provide communication capability to RFID communication enabled devices. Such devices include cameras, PDAs, voice communicator, keyboards, displays, indicators, storage devices, etc. Devices are made RFID communication enabled by providing them with an RFID interface and an RFID tag “front end”. Such an enhanced device communicates with an enhanced portal via an RFID reader/interrogator associated with the portal. The portal may have connection to other communication channels, such as an Ethernet tie to a network, a landline phone connection, a cellular interface, an 802.11 connection, a Bluetooth channel, etc. Such connections allow an RFID communication enabled device to communicate beyond the enhanced portal to the outside world.

    摘要: Methods, systems, and apparatuses for RFID devices, such as reader antennas, are described. A reader antenna includes a quadrature hybrid coupler, a termination element, and an antenna, such as a patch antenna. The quadrature hybrid coupler has first, second, third, and fourth ports. The first port receives an input radio frequency RF signal. The second port outputs a first RF output signal. The third port outputs a second RF output signal. The second RF output signal is shifted in phase by 90 degrees relative to the first RF output signal. The fourth port is coupled to the termination element. The patch antenna has a first point coupled to the first RF output signal and a second point coupled to the second RF output signal. The patch antenna radiates a circularly polarized RF signal due to the received first and second RF output signals. The circularly polarized RF signal may be used to interrogate tags. Furthermore, the reader antenna is integrated into a ruggedized structure that provides environmental protection for the antenna, including providing shock absorption for impacts to the antenna.

    摘要: Methods and apparatus are provided to locate a terminal within a workspace. Radio frequency identification (RFID) tags are provided in known locations, preferably in, on or adjacent the light fixtures or other workspace infrastructure. The terminal comprises an RFID tag interrogation transceiver, processor and memory. The transceiver interrogates the tags which respond with information correlatable with their unique locations. The terminal determines its locations relative to the known locations of responding tags by, for example, varying its transmit power and/or receiver sensitivity and/or by trilateration using, for example, phase or time difference of arrival measurements on the tag response signals. Once it has determined its own location it may transmit or otherwise announce its location as desired by the user. In a preferred embodiment, the natural electromagnetic radiation and/or RADAR cross section backscatter from fluorescent type fixtures, modulated with their position information, acts as the RFID infrastructure beacon.
