Abstract

DISPOSITIVO ELECTRONICO DE DETECCION DE ANOMALIAS EN UNA ZONA. UN OSCILADOR-RECEPTOR (4) EMITE UNA ONDA ALTERNA QUE, AMPLIFICADA POR UN AMPLIFICADOR (7), RECORRE UNA LINEA (1), DE FORMA QUE CREA UN CAMPO ELECTROMAGNETICO EN LA ZONA A CONTROLAR, Y VUELVE AL OSCILADOR-RECEPTOR (4) DESPUES DE PASAR POR UN ATENUADOR (10). CUANDO UN OBJETO O SER SE INTRODUCE EN LA ZONA CONTROLADA, VARIA LOCALMENTE LA IMPEDANCIA, LO QUE AFECTA A LA ONDA Y EL OSCILADOR-RECEPTOR (4), AL DETECTARLO, DISPARA UN DISPOSITIVO DE ALARMA (12).
