| abstract | ABSTRACT OF THE DISCLOSURE A proximity detection system is disclosed including an oscillator circuit which has an electro-magnetic resonator characterized by a hollow metallic chamber, an oscillator having negative resistance charac-teristics fixed in the chamber, and a source of direct current connected in series with the oscillator and the chamber. A radiating iris opening is provided in the chamber of a size and disposition such that oscillation of said oscillator circuit means is damped except in the proximate presence of an object before the iris. A detector responsive to a characteristic change in output in the oscillator circuit produced by the oscillation thereof such as an operational amplifier or comparator produces an output indicative of the presence of an object. |
