Abstract:

An assembly used to protect the driver or occupant of a motor vehicle, particularly police officers or the like from assailants surreptitiously approaching the automobile, when parked without the knowledge of the vehicle's occupants. The detection assembly comprises a plurality of motion detectors mounted on the exterior of the vehicle and cooperatively disposed relative thereto so as to monitor a surrounding area or perimeter of substantially 360 degrees.

Abstract:

The security detection and location system includes a plurality of monitoring stations that are spaced from each other. Each monitoring station includes its own solar rechargeable battery, a receiver, an alarm circuit and a communications device such as a telephone dialer or a radio frequency (RF) transmitter. The security system operates in conjunction with a plurality of portable transmitters that can be actuated to transmit a distress signal by a person carrying one of the transmitters. When the portable transmitter issues a distress signal, the receiver in a monitoring station issues a command signal which activates two independent circuits, the alarm circuit and the communications circuit. The alarm circuit generates an audible sound in the locale of the monitoring station and the communications circuit sends a signal unique to that monitor to a central response or control unit.
