Abstract
UN SISTEMA PARA INSPECCIONAR UNA CONDUCCION (18), EXCENTRICA O NO COMPRENDE LOS PASOS PARA DIRIGIR UN RAYO (20) DE UN EXTREMO DEL CONDUCTOR AL OTRO Y DISPONE DE MEDIOS DE DETECCION (24, 158) LOS CUALES SON PROVISTOS CON UN CUERPO RECEPTOR DE LUZ (50, 50) QUE TIENEN UNA SUPERFICIE RECEPTORA DE LUZ (56, 56) PARA RECIBIR EL RAYO Y UNA CAMARA DE TELEVISION (60, 60) PARA TOMAR UNA FOTO DEL CUERPO RECEPTOR DE LUZ, LA CONDUCCION SE MUEVE AXIALMENTE PROCESANDO UNA SEÑAL DE SALIDA DE LA CAMARA DE TELEVISION MIENTRAS MANTIENE LA POSICION DEL CUERPO RECEPTOR DE LUZ PARA TENER UNA PREDETERMINADA RELACION CON LA SUPERFICIE INTERIOR DE LA CONDUCCION E INSPECCIONAR SI LA CONDUCCION ES EXCENTRICA O NO EN LAS BASES DEL RESULTADO DEL PROCESO.
