    Abstract: A system includes an identification circuit, a grid antenna, a receiver, and a processor. The identification circuit includes resonant circuits formed on a substrate within a perimeter. Identification may be based on a quantity or physical arrangement of detected resonant circuits within the perimeter. One resonant circuit provides a reference signal. Any resonant circuit may be tuned in accordance with the reference signal by the addition or subtraction of reactance formed on the substrate. A capacitance of a first group of capacitors located outside a turn of an inductor is roughly equal to a capacitance of a second group of capacitors located inside the turn. Any resonant circuit may also be tuned by affixing a resonance modifying element, for example a sticker, to the identification circuit. The grid antenna provides antenna field patterns, one for each cell location. The receiver communicates with the identification circuit via the grid antenna. The processor controls the receiver according to a method including: (a) detecting a first signal at a first grid location; (b) determining an offset as a difference between a frequency of the first signal and a predetermined frequency; (c) detecting a second signal at a second grid location; (d) determining an identification in accordance with the first and second locations, the second signal, the offset determined in step (b), and any offset accomplished by a sticker; and (e) determining an orientation in accordance with the first and second grid locations.

    Abstract: An object identification system includes a monitor and a plurality of transceivers that communicate over a common medium. The monitor includes a first transmitter, a first receiver, and a processor. Each transceiver includes a resonant circuit, a transmitter, a receiver, and an antenna coupled to the resonant circuit. The processor performs a method for performing transceiver communication that includes the steps of: (a) transmitting from the first transmitter a first frequency for a first duration; (b) after lapse of the first duration, receiving via the first receiver a response signal from at least one of the resonant circuits; (c) determining a second frequency from the received response signal; and (d) performing transceiver communication using the second frequency. Transceivers of the type having a resonant circuit coupled to an antenna, when operating in close proximity to each other, may interfere with the response from a single transceiver by absorbing the energy intended to be received by the transceiver, absorbing the energy transmitted by the transceiver, or altering the resonant frequency of the resonant circuit. By determining the second frequency for transceiver communication, the monitor may establish communication with the single transceiver at a frequency better suited for transferring operative power to the transceiver, conducting an interrogation protocol for identifying the transceiver, or for data transfer.
