Abstract

PROCESO Y DISPOSITIVO PARA DETECTAR EL DESPLAZAMIENTO DE DOS ELEMENTOS. EL DISPOSITIVO COMPRENDE UN CIRCUITO MAGNETICO REMANENTE EN DOS PARTES (3A, 3B) CADA UNA DE LAS CUALES TIENE UNA POSICION ASOCIADA A LA DE UN ELEMENTO. MIENTRAS QUE ESTE CIRCUITO ES MAGNETIZADO, DESMAGNETIZADO Y REMAGNETIZADO, SUS CAMBIOS DE ESTADO SON DETECTADOS Y PERMITEN REVELAR, INCLUSO A POSTERIORI, CUALQUIER EVENTUAL DESPLAZAMIENTO RELATIVO DE LOS ELEMENTOS (1 Y 2).
