Abstract

MARCADOR PASIVO QUE INCLUYE UN CIRCUITO SINTONIZADO (10,12) CON UNA INDUCTANCIA Y UNA CAPACITANCIA PORTADAS POR UN PORTADOR (14) ENCERRADO DENTRO DE UNA ESFERA HUECA (16) PARCIALMENTE LLENA CON UN LIQUIDO (18) PARA QUE EL PORTADOR FLOTE LIBREMENTE. LA INDUCTANCIA INCLUYE UNA BOBINA (10) QUE, CUANDO EL PORTADOR (14) ESTA FLOTANDO POSICIONA EL EJE DE LA BOBINA, QUE SE ACERCA MAS A LA VERTICAL QUE A LA HORIZONTAL. EL MARCADOR PASIVO ESTA ENTERRADO EN RELACION A PARTES DE SERVICIOS COMO GAS, TELEFONO, AGUA Y LINEAS ELECTRICAS, PARA UTILIZARSE EN LA LOCALIZACION DE DICHAS PARTES CUANDO SEA NECESARIO.
