Abstract:
1. A portable electronic tracking device to monitor location coordinates of one or more individuals and objects, the device comprising: transceiver circuitry to receive at least one portion of a receive communication signal comprising location coordinates information; accelerometer circuitry to measure displacements of the portable electronic tracking device, wherein the displacements comprise movements of an object or individual associated with the device; a battery power monitor configured to activate and deactivate at least one portion of signaling circuitry in response to the accelerometer circuitry detecting a substantially stationary position of the electronic tracking device since last known location coordinate measurement; and processor circuitry configured to process the displacements, to associate the displacements with a specified pattern, and to generate an alert message in response to the specified pattern.
