Abstract

PROCEDIMIENTO Y DISPOSITIVO DE PROTECCION DE LOCALES CONTRA LA INTRUSION. CONSISTE EN EMITIR UNA ONDA ACUSTICA CONSTITUIDA POR TRENES DE IMPULSOS MODULADOS LINEALMENTE EN FRECUENCIA EN UNA BANDA (B) COMPRENDIDA ENTRE 500 HZ Y 5 KHZ DURANTE UN TIEMPO LIMITADO (T) COMPRENDIDO ENTRE 5 Y 20 MILISEGUNDOS CON UN PERIODO DE RECURRENCIA DEL TIEMPO DE REVERBERACION DEL LOCAL A PROTEGER. EL DISPOSITIVO COMPRENDE: UN EMISOR (10) Y UN DETECTOR (20) DE SEÑALES ACUSTICAS; UN GENERADOR (12) DE TRENES DE IMPULSOS MODULADOS LINEALMENTE EN FRECUENCIA DE UN ALTAVOZ OMNIDIRECCIONAL (11) PARA DIFUNDIR EN EL LOCAL LOS TRENES DE IMPULSOS, COMPRENDIENDO EL DETECTOR (20) UN MICROFONO (21) Y MEDIOS (22) DE ACCIONAMIENTO DE LAS SEÑALES RECIBIDAS POR EL MICROFONO.
