Abstract
EL INVENTO SE REFIERE A UN METODO Y UN APARATO PARA DETECTAR UN CODIGO DE BARRAS DE UNA SEÑAL DE CODIGO DE BARRAS QUE FORMA ESENCIALMENTE UNA SECCION TRANSVERSAL DE UN MODELO DE CODIGO DE BARRAS QUE, POR IRRADIACION, EMITE LUMINISCENCIA DESDE EL FONDO DE UN PORTADOR POR ACCION FLUORESCENTE. LA DETECCION SE REALIZA VERIFICANDO LA SEÑAL DE CODIGO DE BARRAS (F) (T) DENTRO DE CADA AREA (ZG1, TIS) DENTRO DE LA CUAL PUEDE ESPERARSE UNA BARRA, CON UN CRITERIO DE BARRAS (THR, MTHR) OBTENIDO POR LA PREDICCION, CON AYUDA DE UNA TABLA DE PREDICCION (TABLA 1), DE UN VALOR DE SEÑAL DE FONDO LOCAL (AGR) DERIVADO LOCALMENTE DE LA SEÑAL DE CODIGO DE BARRAS (F) (T). EN ESTE METODO SE APROVECHA EL HECHO DE QUE, EN PRIMER LUGAR, ENTRE LAS BARRAS PRESENTE INVARIABLEMENTE EL FONDO DEL PORTADOR ESTA, CREANDO UNA APROXIMACION DE FONDO PERIODICA FIABLE DEL VALOR DE LA SEÑAL DE CODIGO DE BARRAS POSIBLE Y, EN SEGUNDO LUGAR, HAY UNA CIERTA CORRELACION ENTRE UN FONDO Y LA CONTRIBUCION DE LA SEÑAL SUMADA EN RESPUESTA ALA LUMINISCENCIA DE LAS BARRAS DEL FONDO BAJO LA IRRADIACION. LA TABLA DE PREDICCION SE COMPILA DE ANTEMANO A PARTIR DE UNA SERIE DE VALORES ION MAXIMA DE LA MISMA Y LA RESPUESTA MINIMA DE BARRAS CORRESPONDIENTE. LAS PROPIEDADES DE LA TINTA UTILIZADA PARA LAS BARRAS Y LOS MEDIOS DE CAPTACION (5, 61) PARA OBTENER LA SEÑAL DE CODIGO DE BARRAS SE EXPRESAN EN ESTOS VALORES. LA VENTAJA ES QUE LA INFLUENCIA DEL FONDO, PRINCIPALMENTE DEBIDO A LA LUMINISCENCIA LOCAL O GLOBAL DEL PROPIO FONDO, NO AFECTA ADVERSAMENTE A LA FIABILIDAD DE UNA DECISION "BARRA / NO BARRA".
