Abstract

LA INVENCION SE REFIERE A UN SENSOR DE ANGULO DE DIRECCION EN DONDE LOS VALORES ANGULARES SE DETERMINAN A PARTIR DE LA POSICION DE UN DISCO DE CODIGO (1) QUE TIENE UNA PISTA INCREMENTAL Y UNA PISTA DE CODIGO. PARA PODER EXPRESAR EN LA PISTA DE CODIGO (3) LA PRECISION DEFINIDA POR PALABRAS DE CODIGO DE OCHO PASOS UTILIZANDO PALABRAS DE CODIGO DE SEIS PASOS, SE SUPLEMENTAN LAS PALABRAS DE CODIGO DE SEIS PASOS CON 2 BITS QUE RESULTAN DEL ESTADO MOMENTANEO DE LA PISTA INCREMENTAL (2) ESCANEADA POR DOS DETECTORES (4, 5).
