Abstract: A time-critical automatic, instantaneous and direct (dispatcherless) vehicle to vehicle, auto-routing Police/Emergency Medical Service vehicle, notification and response system that provides interactive and direct communication between a vehicle or individual in need of immediate emergency assistance, and the nearest (primary) mobile P/EMS vehicle that is available to respond to the exigency. Rapid notification and response is achieved by using a conventional Global Positioning System (GPS), a cellular phone optionally having positioning capability for transmitting the emergency signal, and a vehicle fleet management system (FMS). The latter is modified and designed to operate with a flawless vehicle theft and/or accident characterization technology. The central processing unit processes data from the GPS/FMS automatically and routes a distress call to a secondary or tertiary P/EMS vehicle, i.e.

Abstract: A real-time (instantaneous) vehicle anti-theft warning, notification and tracking system is disclosed that eliminates false alarms by comparing a calculated displacement profile representing the characteristics of a measured displacement (or apparent displacement) of a vehicle with predetermined displacement profiles. The present invention employs a displacement sensor with a unique monitoring program that measures the rate-of-change, direction, and/or duration of displacement of a vehicle (e.g., an automobile or aircraft) over time, and accurately characterizes real and virtual displacements based on the comparison of the calculated displacement profile with the predetermined displacement profiles. The invention also may include GPS/cellular indication capability to alert the vehicle owner of a theft event, and may also include a discrimination indicator to alert the vehicle owner that GPS/cellular capability is not available.
