Abstract
In accordance with at least one embodiment, a portable data terminal generally comprising a battery: a central controller, a GPS system, and an auxiliary processor. The central controller that has a sleep state wherein at least some of the functionality of the central controller is limited to conserve battery power. The auxiliary processor may be selected based, at least in part, on power draw. In particular, it is desirable for the auxiliary processor to use less power than the central controller when the central controller is fully activated. The auxiliary processor monitors the output of the GPS system and wakes the central controller from a sleep state based on the output of the GPS system.
