Abstract: A surveillance system is disclosed for preventing violence which may occur during attempts of armed robberies or acts of terrorism, thereby improving the security of persons within public buildings, governmental and industrial facilities. The system utilizes one or more optical imaging device(s) strategically located throughout the facility under surveillance, and in particular the entry ways therein for detecting potentially armed individuals or intruders entering or moving about the facility. The optical imaging devices operate in conjunction with a computor system having one or more databases containing information indicative of the presence of weapons and representing the types thereof which may be brandished by one or more persons entering the area under surveillance, and data indicative of the spectrum of human pre-aggressive movements, postures and gestures. The databases enable the system to differentiate between law enforcement personnel and their weapons from potential intruders and their weapons.

Abstract: An arrangement was devised for the delivery of stereophonic soundwaves through the mastoid bone structure of the human skull. The system allows for the partial bypassing of the use of the auditory canals, and for the conduction of audio output signals generated in a stereo radio, tape player or other audio device, leaving the auditory canals unobstructed and able to receive airborne sound waves. The system includes one or more accoustical transducers applied to the sides of a person's head adjacent each of his ear canals and in accoustical conduction with the mastoid bone structure thereat.

Abstract: A countersteering system is disclosed for a road vehicle including sensors arranged to sense the speed of steerable wheels in response to changes in road surface texture, the lateral movement of the wheels in response to skid movement, and the rotational motion of the steering wheel for the vehicle, and to produce respective signals according therewith. A control system is devised to receive these signals and to produce a control signal in accordance therewith as a corrective routine and to impress this control signal in a force producing mechanism to impart movement of the steerable wheels for corrective purposes. The control system is devised to differentiate time lags between occurrances of repetitive sequences of at least one of the signal in its production of the control signal.

Abstract: A passive optical system (POS) is disclosed for detecting the presence of an object, such as a vehicle, in one or more areas of surveillance. The system includes one or more sensor tubes, each having one or more photosensitive devices arranged interiorly at one end and an opening in a wall at the other end, capable of focusing light rays emanating from a specific area of surveillance. Variations in the light rays caused by an object moving into or out of the area of surveillance cause corresponding fluctuations of the light rays impinging on the photosensitive devices, which, in turn, produce variation in a signal. The signal may be utilized to inform the driver of the host vehicle of a nearby vehicle or, when the POS is connected into a cruise control system, to manipulate the host vehicle, accordingly.
