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.

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.
