    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 antenna for using within an allocated bandwidth having a nominal center frequency includes a support member, a first antenna structure, and a second antenna structure. The first antenna structure has a return loss maximized at a first optimal frequency. The second antenna structure has a return loss maximized at a second optimal. The difference between the first optimal frequency and the second optimal frequency is more than 10% of the allocated bandwidth but less than 100% of the allocated bandwidth.

    摘要: The present invention is directed to systems that use frequency selective surfaces (FSS) to aid in the operation of radio frequency identification (RFID) devices and products. In one embodiment, a system for interrogating radio frequency identification (RFID) tags includes a conveyor belt and an RFID reader. The conveyor belt has a first surface and a second surface. The first surface is configured to receive an item to which an RFID tag is affixed and the second surface is configured to slide on a metal slide plate. The RFID reader is configured to transmit instructions embodied in a radio frequency (RF) signal to the RFID tag, wherein the metal slide plate is positioned between the RFID reader and the RFID tag and comprises a frequency selective surface that is substantially transparent to the RF signal.

    摘要: Methods, systems, and apparatuses for a reader transceiver circuit are described. The reader transceiver circuit incorporates a frequency generator, such as a surface acoustic wave (SAW) oscillator. A reader incorporating the reader transceiver circuit is configured to read a tag at very close range, including while being in contact with the tag. The transceiver can be coupled to various host devices in a variety of ways, including being located in a RFID reader (e.g., mobile or fixed position), a computing device, a barcode reader, etc. The transceiver can be located in an RFID module that is attachable to a host device, can be configured in the host device, or can be configured to communicate with the host device over a distance. The RFID module may include one or more antennas, such as a first antenna configured to receive a magnetic field component of an electromagnetic wave and a second antenna configured to receive an electric field component of an electromagnetic wave. The RFID module may include a detector that is configured to determine if the RFID module is positioned in proximity to an object, such as a RFID tag. The detector may operate as a trigger for the RFID module, to enable or trigger a function of the RFID module.

    摘要: Described is a device including a processor, a wireless arrangement including an antenna, and a memory arrangement storing first data and second data. The first data includes predetermined antenna characteristics and the second data includes predetermined triggering characteristics for triggering a function of the device. When third data fails to match the first data, the processor compares the third data to the second data, the third data being indicative of characteristics changes of the antenna. The processor triggers a corresponding function of the device as a function of the third data and the second data.
