Patent ID: 8315563

Claim:
A remote communications device comprising: communication circuitry configured to communicate wireless communication signals; and sensor circuitry configured to sense at least one condition with respect to the remote communications device and to generate data indicative of the at least one sensed condition; wherein the communication circuitry is coupled with the sensor circuitry and is configured to receive and to process some of the wireless communication signals and to output the data generated by the sensor circuitry externally of the remote communications device based on a duty cycle of the remote communication device; and wherein the remote communications device is capable of powering down to conserve energy and capable of powering up in response to an electronic signal, and further includes a second receiver that is configured to screen a radio frequency transmission and provide, on the basis of specific data identified therein, the electronic signal in order to power up the remote communications device, the second receiver being adapted to draw less current than the communication circuitry while awaiting receipt of and listening for a radio frequency transmission.
