53193504, Jun 7, 1994

Filed:

Dec 29, 1992

Appl. No.:

7/990982

Inventors:

Frank DeMarco - Coral Springs FL
Dennis DeMarco - Margate FL

International Classification:

B60R 2510

US Classification:

340435

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. The occupants of the vehicle are warned by an alarm assembly which provides both audible and visible communication indicating that motion has been detected within the monitored external area surrounding the vehicle. In a preferred embodiment the plurality of motion detectors each comprise a microwave and passive infrared detector structure.

Appl. No.:

7/025051

Inventors:

Frank G. DeMarco - Coral Springs FL
Dennis D. DeMarco - Margate FL

International Classification:

G08B 2500

US Classification:

340574

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.

International Classification:

G03B 1100

US Classification:

Abstract:

A camera system creates special effect images in the out-of-focus highlights of a photographic image by inserting a transparent image cell between the objective lens and focal plane of the camera. The image cell can be a transparency bearing the desired special effect image. Alternatively, the image cell can be a transparent liquid crystal display (LCD) to provide either still or animated special effect images. The special effect image appears in any out-of-focus highlights (e. g. , background street lights or headlights) in the photographic image, but does not otherwise affect the appearance of the photograph. The image cell is held by a tubular housing having connectors at each end to removably engage the standard connectors on the camera body and objective lens. The image cell can be held in a fixed optical position within the housing, for example, by means of a slide or a gate with spring clips. Alternatively, the image cell housing can include an image cell holder that allows rotation or translation of the image cell along the optical axis between the objective lens and camera.
