Abstract

DETECTOR DE METALES CON TRANSDUCTORES ELECTROMAGNETICOS FALSEADOS Y CIRCUITO CORRECTOR DE LAS DESUNIFORMIDADES, DISPUESTO PARA INDICAR EL PASO DE MASAS METALICAS Y EN PARTICULAR DE ARMAS, A TRAVES DE ACCESOS CONTROLADOS. CONSISTE EN DOS TRANSDUCTORES TX Y RX, CADA UNO FORMADO, AL MENOS, POR DOS ENVOLTURAS ENTRE ELLOS FALSEADOS EN ALTURA Y EN UN CIRCUITO ELECTRONICO MEDIANTE EL CUAL LAS SEÑALES EN RECEPCION SON ANALIZADAS, DESPUES CONFRONTADAS ENTRE SI Y CON LOS VALORES MEMORIZADOS EN UN CUADRO PARA DEDUCIR EL COEFICIENTE CORRECTIVO, CON EL CUAL, LA SEÑAL PREDETERMINADA, ENTRE AQUELLAS RECIBIDAS, DEBE SER AMPLIFICADA PARA COMPENSAR, Y POR TANTO, CORREGIR LA DESUNIFORMIDAD DE REVELACION EN ALTURA DEL PAVIMENTO DEL DETECTOR DE METALES.METAL DETECTOR WITH FALSE ELECTROMAGNETIC TRANSDUCERS AND CORRECTIVE CIRCUIT OF MALFUNCTIONS, ARRANGED TO INDICATE THE PASSAGE OF METAL MASSES AND IN PARTICULAR OF WEAPONS, THROUGH CONTROLLED ACCESSES. IT CONSISTS OF TWO TX AND RX TRANSDUCERS, EACH FORMED, AT LEAST, BY TWO WRAPS BETWEEN THEM FALSE IN HEIGHT AND IN AN ELECTRONIC CIRCUIT THROUGH WHICH THE SIGNALS IN RECEPTION ARE ANALYZED, THEN CONFRONTED BETWEEN YES AND WITH MEMORIZED VALUES TO DEDUCT THE CORRECTIVE COEFFICIENT, WITH WHICH, THE DEFAULT SIGNAL, AMONG THOSE RECEIVED, MUST BE AMPLIFIED TO COMPENSATE, AND THEREFORE, CORRECT THE DISUNIFORMITY OF REVELATION AT THE HEIGHT OF THE METAL DETECTOR FLOOR.
