Object identification system with adaptive transceivers and methods of operation
First Claim
1. An object identification system comprising a transceiver having circuitry which includes:
- a receiver section operable to receive a wireless monitor transmitter signal that includes a monitor identification of a monitor that transmits the wireless monitor transmitter signal, the monitor identification to be stored in a memory of the transceiver; and
a transmitter section operable to transmit wireless transceiver signals which each include an identification associated with said transceiver, said transmitter section being responsive to receipt by said receiver section of said monitor transmitter signal, for including in said wireless transceiver signals, the monitor identification stored in said memory;
wherein said monitor transmitter signal includes a command portion, and wherein said transceiver is responsive to said command portion for effecting a control function within said transceiver.

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.
