Abstract: A covert surveillance system for viewing images from a remote location is provided. The surveillance system provides a mirror, lens and camera arrangement within a small enclosure that allows full 360 degree pan, tilt, zoom, focus and iris control from a remote location. The system receives control commands such as rotate left, zoom out and tilt down via a radio receiver, and controls the camera accordingly. Images viewed by the camera are transmitted to a remote receiver for display on a monitor, or for recording. Continuous camera rotation is achieved by use of a specialized conductive drum that provides continuous electrical contact between camera signals and camera control. In one embodiment, the surveillance system is mounted in place of a photo detector in a street lamp, making the camera virtually undetectable. In addition, a rotatable directional antenna is included in the surveillance system to allow surveillance at great distances from the system.

Abstract: A radio beacon for a nautical emergency rescue system includes a flotation housing containing an antenna in an upper portion, a ground plane and a transmitter in a central portion, and batteries in a lower portion. When placed in the water, the lower section is submerged and the central section is at surface level, enabling contact between the ground plane and the water via conductors that pass through the housing. The upper portion projects above the water to permit efficient radiation from the antenna, which consists of a vertical rod and a coaxial cylindrical can that is open at the bottom end. The upper end of the rod is attached to the center of the can closed end. The radio transmitter is frequency modulated in a distinctive pattern, and operates with a duty cycle that permits detection and direction finding of multiple such beacons.
