Abstract

UN DETECTOR DE METALES QUE TIENE UN RESPONDEDOR A SEÑAL RECIBIDA PARA DETECTAR OBJETOS METALICOS Y QUE TIENE UN PANEL (139) DE REPRESENTACION QUE PUEDE SIMULTANEAMENTE REPRESENTAR UNA PLURALIDAD DE ANGULOS DE FASE (205) SOBRE UNA ESCALA ASOCIADA CON LA SEÑAL RECIBIDA. ADICIONALMENTE, EL PANEL DE REPRESENTACION PUEDE REPRESENTAR SIMULTANEAMENTE SOBRE LA OTRA ESCALA (210) UNA SEGUNDA VARIABLE ASOCIADA CON LA SEÑAL RECIBIDA EN CADA ANGULO DE FASE PARTICULAR. LA SEGUNDA VARIABLE ES SELECCIONABLE POR EL USUARIO Y PUEDE SER O (1) UN CONTADOR DEL NUMERO DE VECES EN QUE LA AMPLITUD DE LA SEÑAL EXCEDE UN NIVEL UMBRAL PREDETERMINADO EN UN ANGULO DE FASE PARTICULAR, O (2) DE LA AMPLITUD DE SEÑAL CUANDO LA SEÑAL ESTA EN UN ANGULO DE FASE PARTICULAR.
