Abstract:
Apparatus for achieving remote guarding of an area with adjustable effect on unauthorized entrants, comprising:a) an operator station including a signal receiver with television display, radiant energy selection control and energy level controller;b) first sensor means placed about the area for detecting the presence and movements of entrants to the area, the visual effects of later radiation directed toward them, and generating signals in response thereto;c) a source of radiant energy including at least one transmitter of the energy for broadcasting said energy into the area, upon selection of the type of radiant energy from said selection control, and of a level controlled by said energy level controller, said radiant energy of a nature and intensity capable of varying in strength and duration as to cause different observable effects on intruders present in the area who do not leave the area upon command;d) second sensor means placed about the area for detecting the onset of and intensity of the radiant energy broadcast into the area and generating signals in response thereto;e) first transfer means for transferring said generated signals from said first sensor means and separately transferring said generated signals from said second sensor means to said signal receiver in said operator station to allow the operator real-time observation of the area; and,f) second transfer means for transferring control signals from said operator station to said radiant energy source and transmitter to vary the type and intensity of said radiant energy broadcast into the area to prevent further intrusion into the area.
