Abstract

UN MONTAJE SENSIBLE PARA UN SISTEMA DE CONTROL DE INVENTARIO DE ARTICULOS QUE EMPLEA VARIOS SENSORES PARA LA DETECCION DE MARCADORES SENSIBILIZADOS FIJOS A LOS ARTICULOS INVENTARIADOS. PROCESANDO SEÑALES DE CADA UNO DE LOS SENSORES, SE PROPORCIONA UN PATRON DE DETECCION PARA DETERMINAR SI HAY CERO, UNO O MAS DE LOS MARCADORES DENTRO DE LA ZONA DE SENSIBILIDAD.
