Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA MEDICION Y CARACTERIZACION, A ALTA VELOCIDAD, DE MATERIALES MAGNETICOS. EL PROCEDIMIENTO Y DISPOSITIVO PARA LA MEDICION Y CARACTERIZACION, A ALTA VELOCIDAD, DE MATERIALES MAGNETICOS OBJETO DE LA INVENCION, CUYA FINALIDAD ES LA VALIDACION DE DOCUMENTOS QUE INCORPOREN MARCAS CONSISTENTES EN MATERIALES MAGNETICOS, ESTA BASADO EN UN ANALISIS DE SEÑALES SUMINISTRADAS POR LO QUE ESTRUCTURALMENTE SE CONSTITUYE MEDIANTE LA ASOCIACION FUNCIONAL DE UN OSCILADOR (1) QUE GENERA UNA SEÑAL DE BAJA FRECUENCIA QUE ALIMENTA BOBINAS EMISORAS (2), Y UN CONJUNTO DE BOBINAS RECEPTORAS (3), GENERALMENTE EN NUMERO DE DOS (A) Y (B) QUE PUEDEN PRESENTAR DIFERENTES CONFIGURACIONES. LAS BOBINAS RECEPTORAS (3), ESTAN UNIDAS A UN AMPLIFICADOR QUE DISPONE DE DOS SALIDAS (S1) Y (S2), LA SEGUNDA DE LAS CUALES UNA VEZ CONFORMADA, DA LUGAR A UNA SEÑAL (X) QUE SE TOMARA COMO REFERENCIA DE TIEMPOS Y LA PRIMERA, DESPUES DE DIVERSAS TRANSFORMACIONES DA LUGAR A DOS SEÑALES (Y) Y (Z), INTRODUCIENDOSE TODAS ELLAS EN UN MICROPROCESADOR (10) QUE BAJO PROGRAMA Y DATOS DE MARCADORES MAGNETICOS VALIDOS GENERARA SEÑALES (13) DE ACEPTACION O RECHAZO DE DOCUMENTO (14).
