Abstract

PRIMERO, UNA TECNICA DE GUIA DE INTERRUPCION PARA MEDIR LA DURACION DEL ESPACIO Y DATO DE CODIGO DE BARRA, DEL CUAL PERMITE A UN MOCROPROCESADOR DECODIFICAR UN PRIMER CUANTO DE DATOS DE CODIGO DE BARRA DURANTE UNA PORCION SUSTANCIAL DE TIEMPO, EN LA CUAL, EN EL MICROPROCESADOR SE ESTA MIDIENDO LA DURACION DEL ESPACIO Y DATOS DE BARRA DE UN SEGUNDO CUANTO DE DATO DE CODIGO DE BARRA. SEGUNDO, UN METODO PARA LOCALIZAR UN MARGEN DE CODIGO DE BARRA Y ELIMINAR TIPOS DE CODIGO DE BARRA PARA SER PROCESADO PARA PROPOSITO DE DECODIFICACION. RAPIDAMENTE, UNA PROPORCION ENTERA DE ESPACIO Y DATO DE DURACION DE BARRA SIGUIENTE SE COMPARA A UN NUMERO PREDETERMINADO Y SE HACE UNA DETERMINACION, SEGUN EL ESPACIO SEA UN MARGEN BASADO EN LA COMPARACION. PREFERIBLEMETE, LAS DOS TECNICAS SON UTILIZADAS EN CONJUNCION PARA ACELERAR LA DISCRIMINACION AUTOMATICA EN APARATOS QUE BARREN UNA PLURALIDAD DE DIFERENTES TIPOS DE CODIGOS DE BARRAS.
