Abstract

APARATO Y METODO PARA VIGILAR LA PRESENCIA, O CAMBIOS DE VALOR, DE TENSIONES ELECTRICAS. CONSTA DE UN CONDENSADOR; DE UN CIRCUITO DE CARGA PARA EL CONDENSADOR, QUE COMPRENDE UNA PRIMERA RESISTENCIA CONECTADA A UNA PRIMERA TENSION; DE UN CIRCUITO DE DESCARGA PARA DICHO CONDENSADOR, QUE COMPRENDE UNA IMPEDANCIA ENTRE CUYOS EXTREMOS PUEDE APARECER, O APLICARSE, UNA SEGUNDA TENSION Y UNA SEGUNDA RESISTENCIA EN SERIE CON LA MISMA; DE UN CIRCUITO OSCILADOR QUE COMPRENDE UN TRANSISTOR MONOUNION PROGRAMABLE QUE FUNCIONA EN REGIMEN OSCILATORIO; DE MEDIOS PARA APLICAR AL CIRCUITO ANODO-PUERTA DEL TRANSISTOR MONOUNION PROGRAMABLE, UNA TENSION RELACIONADA CON LA TENSION EXISTENTE ENTRE LOS EXTREMOS DEL MENCIONADO CONDENSADOR; Y DE MEDIOS PARA VIGILAR LA PRESENCIA DE OSCILACIONES EN EL MENCIONADO CIRCUITO OSCILADOR.
