Abstract: A system comprising a portable, OBD connectable dongle is in communication with a cellular telephone. The dongle and the cellular telephone are communicatively coupled, allowing the cellular telephone to receive signals from the OBD dongle. The OBD dongle monitors the output signals from the built-in OBD system for a vehicle and relays the signals to the cellular telephone. The cellular telephone is programmatically configured to interpret the signals provided by the OBD system to determine the status of the vehicle and, in certain pre-determined situations, send one or more messages to request assistance or support. The most preferred embodiments of the system are also GSM and GPS enabled, thereby providing GSM and GPS positioning information that can be used in conjunction with the accelerometer data to monitor and detect predetermined events and, based upon the specific nature of the event, generate one or more alerts.

Abstract: A system comprising a portable, hand-held device having an accelerometer controlled by a new protocol which acts to output accurate and rapid communication concerning one or more predetermined events to a monitoring service and to receive input communications through satellite communication and/or other communication means. In another embodiment, an installed device such as an AVL comprises communication means for short burst communication over satellite. The most preferred embodiments of the present system are also GSM and GPS enabled, thereby providing GSM and GPS positioning information that can be used in conjunction with the accelerometer data to monitor and detect predetermined events and, based upon the specific nature of the event, generate one or more alerts.
