1. A control device responsive to RF signals transmitted by an RF transmitter, the RF transmitter adapted to transmit a number of consecutive packets at a predetermined transmission rate during a given transmission event, each of the consecutive packets characterized by a packet length, the control device comprising:
an RF receiver adapted to receive packets from the RF transmitter, the RF receiver configured to be periodically enabled for a sample time period to determine if the RF transmitter is transmitting one of the consecutive packets, the RF receiver configured to enter a sleep mode for a sleep time period between consecutive sample time periods if the RF receiver determines that the RF transmitter is not transmitting one of the consecutive packets during the sample time period; and
a controller operatively coupled to the RF receiver, wherein after determining that the RF transmitter is transmitting one of the consecutive packets during the sample time period, the controller is configured to receive a subsequent packet;
wherein the sleep time period of the RF receiver is longer than the packet length of each of the consecutive packets, and the sample time period and the sleep time period between sample time periods are sized such that the sample time period coincides with at least one of the predetermined number of consecutive packets in the transmission event.
