Abstract
The present invention is a portable motion-activated position reporting device. In one embodiment, a controller is coupled with an interrogator component, a position determining component, a wireless communications component, and an initiating component. In one embodiment, the initiating component detects motion of the position reporting device and generates a signal to the controller indicating the motion. The controller, in response to the signal, activates the interrogator component and the position reporting device.
