Patent ID: 8255011

Claim:
A mobile communication device comprising: a processor; a data acquisition device for acquiring data and providing it to the processor; a transceiver for communicating with a central radio and a secondary communications device; a first timer for counting down a first random delay time period and for temporarily shifting the processor and the transceiver from low-power sleep modes to active wake modes upon countdown of the first random delay time period so that the processor and transceiver can transmit at least some of the data to the central radio while in their active wake modes, wherein the first random delay time period is received from the central radio via the transceiver; and a second timer for counting down a second random delay time period and for temporarily shifting the processor and the transceiver from low-power sleep modes to active wake modes upon countdown of the second random delay time period so that the processor and transceiver can communicate with the secondary communications device while in their active wake modes.
