Abstract

The circuit (1) comprises a portable generator (7) for generating a predetermined signal and has an output connected to a first transducer (8) for transmitting the signal to a first body (3). A processing mechanism (4) analyses a signal picked up by a second transducer (11) on a second operator (5) and detects the significant presence of the predetermined signal. The transmitter circuit (2) comprises an oscillator (7) producing an alternating square wave of a predetermined frequency in the audio frequency band sufficiently greater than the mains frequency.
