Abstract:
1. A vehicle, comprising: a plurality of components including an interrogator arranged to transmit RF signals and receive responsive RF signals; and at least one RFID assembly, each of said at least one RFID assembly including a sensor and an associated RFID switch that controls wireless transmission of data provided by said sensor, said interrogator being arranged to include in transmissions therefrom an identification of an RFID switch associated with a sensor from which data is sought, said RFID switch being arranged to receive an RF signal from said interrogator and only upon receipt of an RF signal containing its identification, enable said sensor to transmit a sensor signal to said interrogator, said RFID switch thereby precluding transmission of the sensor signal from said sensor to said interrogator when said RFID switch does not receive an RF signal containing its identification, whereby a property being monitored by said sensor is determinable from said sensor signal transmitted from said sensor to said interrogator.
