Abstract: A system (10) and apparatus (32) for detecting unauthorized or unsafe movement or crash detection of a moveable object (30) where the system includes a GPS receiver (32), cellular modulator (32), processor (32), pager modem (32), sensor (32) and two-way pager (34). When the system (32) is coupled to a moveable object (30) and is armed via the pager, the sensor is monitored by the processor to determine when a possible theft of the moveable object may be occurring. When the system is coupled to a moveable object and is not armed, the sensor is monitored by the processor to determine when a possible crash detection of the moveable object may be occurring or occurred.

Abstract: A system and apparatus for detecting unauthorized movement of a moveable object where the system includes a GPS receiver, cellular modulator, processor, pager modem, sensor and two-way pager. When the system is coupled to a moveable object and is armed via the pager, the sensor is monitored by the processor to determine when a possible theft of the moveable object may be occurring. In an embodiment, the sensor is a multiple axis accelerometer. In one embodiment the accelerometer is a two axes accelerometer where the sensor detects small movements of the object is two axes. When the sensor is triggered, the processor pages the two-way pager. The processor also determines the system's location via the GPS receiver. The processor generates a message including the system's location and unique system identifier. The processor transmits the message to a monitoring center via a cellular network (and the cellular modulator).
