Abstract
METODO Y APARATO PARA LA EXPLORACION DE CODIGOS DE BARRAS A VELOCIDAD VARIABLE. SE MUESTRA UN METODO Y APARATO PARA ESCANEAR UN CODIGO QUE SE PUEDA LEER OPTICAMENTE, COMO POR EJEMPLO UN CODIGO DE BARRAS (20) A UNA VELOCIDAD VARIABLE DE LECTURA. TAL VELOCIDAD VARIABLE DE LECTURA TIENE EL EFECTO DE NORMALIZAR LA DENSIDAD DE LOS ELEMENTOS DEL CODIGO (21) QUE DEBEN SER LEIDOS, Y POR LO TANTO ELIMINA LA NECESIDAD DE QUE EL OPERADOR DEL SCANNER TENGA QUE DECODIFICAR DURANTE EL CURSO DEL CODIGO DE BARRAS (20) PARA VARIAR LA DISTANCIA ENTRE EL SCANNER (10) Y EL CODIGO OPTICO (20) PARA UNA ESCALA PREDETERMINADA DE DENSIDADES DE ELEMENTOS (21) DEL CODIGO.
