Abstract

A battery operated device includes a receiver for receiving a transmission that includes a postamble. A sensor, in a tire, measures a parameter of the tire and outputs data indicative of the parameter. A microprocessor is coupled to the receiver and the sensor. The microprocessor is configured to periodically partially awaken to determine whether the transmission is likely a forward link packet (FLP) by examining the postamble, and to transmit the data in a reverse link packet (RLP) in response to confirming that the transmission is a FLP.
