1. A mobile communication device comprising:
- a processor;
a data acquisition device for acquiring data and providing it to the processor;
a transceiver for transmitting at least some of the acquired data to an external device; and
a low-power clock for counting down a 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 random delay time period so that the processor and transceiver can transmit at least some of the data to the external device while in their active wake modes,

Abstract
A mobile communication device includes a processor; a data acquisition device for acquiring data and providing it to the processor; a transceiver for transmitting at least some of the acquired data to an external device; and a low-power clock. The low-power clock counts down a random delay time period and temporarily shifts the processor and the transceiver from low-power sleep modes to active wake modes so that the processor and transceiver can transmit at least some of the acquired data to the external device while in their active wake modes.

10. A mobile communication device comprising:
-
a processor having a low-power sleep mode and an active wake mode; a data acquisition device for acquiring data and providing it to the processor; a transceiver for transmitting at least some of the acquired data to an external device, the transmitter having a low-power sleep mode and an active wake mode; a low-power clock for counting down a random delay time period and for shifting the processor and the transceiver from their low-power sleep modes to their active wake modes upon countdown of the random delay time period so that the processor and transceiver can transmit at least some of the acquired data to the external device while in their active wake modes; and a low-power wake-up circuit operable to receive a wake signal from the external device and shift the processor and the transceiver to their active wake modes independent of the random delay time period. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of exchanging communications between a central radio and at least one mobile radio, the method comprising:
-
counting down a random delay time in the mobile radio; upon expiration of the random delay time, switching a processor and transceiver in the mobile radio from low-power sleep modes to active wake modes; while the processor and transceiver are in their active wake modes, transmitting data from the mobile radio to the central radio and receiving communications at the mobile radio from the central radio; and switching the processor and the transceiver back to their low-power sleep modes. - View Dependent Claims (18, 19, 20, 21)
