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.

Power management apparatus and methods for portable data terminals

A data collection system including a portable data terminal and a base for receiving the portable data terminal. The portable data terminal having a first interface for receiving power and a second interface for connecting to a communication link. The base having a housing adapted to receive and support the portable data terminal, a power supply receiving power from an external power source and upon insertion of the portable data terminal into the housing supplying power to the first interface on the portable data terminal, a communication link adapted to interface with the portable data terminal, and a location determination device, such as a GPS receiver, connected to the communication link and supplying the portable data terminal with location data via the communication link.
