Abstract

EL DISPOSITIVO ESTA ASOCIADO A UN OBJETO A IDENTIFICAR, TAL COMO UNA CANALIZACION SUBTERRANEA U OTRO OBJETO EMPOTRADO, POR EJEMPLO, EN UNA OBRA DE INGENIERIA CIVIL. ESTE DISPOSITIVO LLEVA ELEMENTOS DE CODIFICACION DETECTABLES A DISTANCIA, QUE CORRESPONDEN DE UNA MANERA UNIVOCA AL OBJETO A IDENTIFICAR. LOS ELEMENTOS DE CODIFICACION SE PRESENTAN EN FORMA DE UNA SUCESION LINEAL DE HOJAS (1, 11) DE PEQUEÑO ESPESOR, DE MATERIAL ELECTROMAGNETICAMENTE ACTIVO, DISPUESTAS SOBRE O EN UN SOPORTE PROTECTOR (9) ELECTRICAMENTE AISLANTE. LAS HOJAS (1, 11), DE DIMENSIONES (L, R) PREDETERMINADAS, ESTAN SEPARADAS UNAS DE OTRAS POR INTERVALOS (D) TAMBIEN DE VALOR PREDETERMINADO PARA DEFINIR UN CODIGO DETECTABLE POR VIA ELECTROMAGNETICA.
