摘要： The location of unmodified wireless assets in a wireless communication network may be identified using time differences of arrivals of a communication sequence at different network receivers. Time-stamping devices may include correlator circuits in parallel with signal decoders to time-stamp communication sequences. Cellular wireless networks may be frequency-multiplexed to increase spatial time-stamping density. Tags may be attached to passive assets to provide location identification information to network devices. Locations of assets broadcasting standard 802.11 radio frequency structures may be identified. Noise inherent in correlating a communication sequence may be reduced by using a selected correlation function.

摘要： The present disclosure describes a system, methods and apparatus for determining a direction of motion of an RFID tag. An RFID reader is provided that includes an antenna that is tilted at a tilt angle with respect to a detection path. Response signals from the RFID tag are received at the antenna at different times, and an RSSI sample of each response signal is measured. Based on the RSSI samples, an RSSI/time data point is generated for each of the RSSI samples. Each RSSI/time data point defines a measured RSSI value for a particular RSSI sample versus a time that particular RSSI sample was measured. Based on the plurality of RSSI/time data points, the direction of motion of the RFID tag can be determined.

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.

The receiver receives radio frequency signals generated according to a predetermined wireless communication protocol. The envelope detection arrangement screens the radio frequency signals for a predetermined signal which utilizes the predetermined wireless communication protocol and has a predetermined envelope sequence. Upon detection of the predetermined signal, the arrangement transmits a further signal to a computing device coupled thereto. The further signal is an instruction for the computing device to execute a predetermined action.

摘要： Systems and methods for saving power in a distributed RFID system are provided. One RFID reader includes a RFID radio, a data communication radio, and a controller. The controller is configured to compare a current list of RFID tags responding to a current interrogation signal and a previous list of RFID tags responding to a previous interrogation signal to determine if there has been a change in RFID tags responding to the interrogation signals. The controller is also configured to command the data communication radio to transmit a signal to an external computing device if there has been the change in RFID tags, the signal indicative of the change, or not transmit the signal if there has not been a change. An RFID system includes a central computing device, multiple RFID tags, and multiple RFID readers similar to the above RFID reader.
