    Abstract: An antenna assembly is operative for receiving interrogating radiation at a variable frequency tag and generating a corresponding received signal, and for receiving a signature signal and radiating corresponding response radiation. A logic unit is operative for receiving the received signal and outputting the signature signal in response, the signature signal including a signature code for use in identifying the tag. A voltage controlled oscillator is operative for controlling a rate at which the signature code is output; and a power supply is operative for providing an electrical potential difference for energizing the tag. The voltage controlled oscillator is operable to output the signature code at a rate which is governed by the magnitude of the received signal.

    Abstract: A wireless communication device coupled to a wave antenna that provides greater increased durability and impedance matching. The wave antenna is a conductor that is curved in alternating sections. The wireless communication device is coupled to the wave antenna to provide wireless communication. The wireless communication device and wave antenna may be placed on objects, goods, or other articles of manufacture that are subject to forces such that the wave antenna may be stretched or compressed during the manufacture and/or use of such object, good or article of manufacture. The wave antenna, because of its curved structure, is capable of stretching and compressing more easily than other structures, reducing the wireless communication device's susceptibility to damage or breakage that might render the wireless communication device coupled to the wave antenna unable to properly communicate information wirelessly.

    Abstract: Radio-frequency identification (RFID) apparatus and methodology enable a plurality of or all of the RFID tags in a stack of items such as cartons and boxes—including items that do not have a line of sight to a reader—to be read. An RFID system includes RFID tags and a transmission line. The RFID tags are mountable to items to be read and include an RFID circuit that generates tag energy when activated by activation energy from a reader. The transmission line carries activation energy from the reader and tag energy from the tags. The transmission line is positionable in operative or coupling proximately to a plurality of the tags when the plurality of the tags are mounted to items and when the items are stacked. Accordingly, when carrying activation energy from the reader, the transmission line couples with and thereby enables activation of the plurality of the tags. Further, when the plurality of the tags are activated and generating tag energy, the transmission line couples with and carries the tag energy from the plurality of the tags. The transmission line can be configured as an elongated adhesive tape-like structure that can be adhered across a plurality of RFID tags mounted to a plurality of items. The transmission line can also be disposed on an inter-item reading device that can be positioned between adjacent rows of stacked items.

    Abstract: An RFID-based analyte sensor is provided with an antenna adapted to receive energy from an RF field and produce a signal. A sensing material is electrically connected to the antenna and has an electrical property which varies in the presence of an analyte. An energy storage device is also electrically connected to the antenna and is adapted to receive and store energy from the antenna and selectively discharge the stored energy. An initializing element is electrically connected to the energy storage device and is energized by the stored energy discharged by the energy storage device. When the initializing element is energized, it operates to reduce the analyte content of at least a portion of the sensing material, effectively initializing the sensing material.

    Abstract: An RFID tag or label or device includes an RFID chip and an antenna. The antenna is manufactured by weakening a portion of a foil material, which weakened portion may be in a tessellating pattern. The foil material is then placed in contact with adhesive on a substrate. The foil material and substrate are separated, so as to retain on the substrate the portion of the foil material in contact with the adhesive. The foil material remaining on the substrate defines an antenna, which may subsequently be electrically connected to an RFID chip to provide an RFID tag or label or device.

    Abstract: A portable radio-frequency repeater includes a housing and a transceiver. The transceiver is disposed at least partially within the housing and configured to alternatively operate in a transmitting mode and a sleep mode. The transceiver includes an antenna and a control unit. The control unit is in electrical communication with the antenna. When the transceiver operates in the transmitting mode, the control unit is configured to receive an RFID signal from the antenna, convert the RFID signal into a converted RFID signal, and transmit the converted RFD signal to the antenna. When the transceiver operates in the sleep mode, the control unit is configured to detect an interrogation signal from the antenna and not to transmit any converted RFID signal to the antenna.
