    摘要： An apparatus system, and techniques for detecting temperature change are disclosed. The system includes a temperature sensitive antenna that can be included in an RFID tag device. The antenna is associated with a temperature sensitive material that, upon being exposed to a particular temperature level over a time interval, causes at least one of a change in the resonance frequency of the antenna and change in antenna signal strength (e.g., antenna gain). An RFID reader is also provided that sends commands to the tag device and determines the existence of a temperature change based on a comparison of signal strengths received on different frequencies from the antenna.

    摘要： A method for pipelined processing of access commands to a population of radio frequency identification (RFID) tags is provided. The method includes transmitting a first queued access command to a first tag in the population of RFID tags, transmitting a second queued access command to a second tag in the population of RFID tags, and transmitting a status request command to the first tag. The queued access command causes the first tag to perform an operation and upon completion of the operation, to suspend transaction processing. The second queued access command is transmitted while the first tag is performing the command operation. The status request command causes the first tag to resume normal processing.
