Abstract

REPETIDOR (18) DETECTOR DE RADIACION ELECTROMAGNETICA A UNA PRIMERA FRECUENCIA PREDETERMINADA QUE INCLUYE UN CONDUCTOR AMORFO, MAGNETOSTRICTIVO Y FERROMAGNETICO (19), QUE, CUANDO SE EXCITA POR UNA RADIACION ELECTROMAGNETICA A UNA PRIMERA FRECUENCIA PREDETERMINADA EN PRESENCIA DE UN CAMPO MAGNETICO DC DESVIADO, TRANSMITE RADIACION ELECTROMAGNETICA A UNA SEGUNDA E INFERIOR FRECUENCIA PREDETERMINADA QUE ES EL RESULTADO DE DE DIVIDIR LA PRIMERA PREDETERMINADA FRECUENCIA. EL CONDUCTOR DEL DIVISOR DE FRECUENCIA (19) SE PREPARA POR RECOCIDO RAPIDO DE UN CONDUCTOR AMORFO DE ALEACION FERROMAGNETICA QUE HA SIDO FUNDIDA Y REVENIDA. UN ARTICULO DE USO (20) QUE CONTIENE UN REPETIDOR (18) INCLUYENDO UN DIVISOR DE FRECUENCIA (19) PUEDE SER IDENTIFICADO COMO AUTENTICO EN UN SISTEMA DE DETECCION DE PRESENCIA MEDIANTE: RADIACION ELECTROMAGNETICA (28) DE LA PRIMERA FRECUENCIA PREDETERMINADA QUE SE TRANSMITE DENTRO DE UNA ZONA DE VIGILANCIA (30); UN CIRCUITO DIVISOR (19) QUE DETECTA LA RADIACION TRANSMITIDA(28) CON LA PRIMERA PREDETERMINADA FRECUENCIA Y RESPONDE TRANSMITIENDO RADIACION ELECTROMAGNETICA (32) A UNA SEGUNDA E INFERIOR PREDETERMINADA FRECUENCIA QUE ES EL RESULTADO DE DIVIDIR LA PRIMERA PREDTERMINADA FRECUENCIA; Y UN DETECTOR (24) QUE DETECTA LA RADIACION TRANSMITIDA CON LA SEGUNDA PREDETERMINADA FRECUENCIA. EL REPETIDOR (18) TAMBIEN INCLUYE UN TUBO (21) QUE ALOJA EL CONDUCTOR (19) DENTRO DEL ARTICULO (20), DE FORMA QUE EL CONDUCTOR (19) PUEDA VIBRAR MECANICAMENTE CUANDO ES EXCITADO POR UN CAMPO ELECTROMAGNETICO CON LA PRIMERA PREDETERMINADA FRECUENCIA CARACTERISTICA DEL CODUCTOR.
