Abstract
MEJORAS EN METODOS DE DETECCION NO INVASIVOS PARA GLUCOSA Y OTROS CONSTITUYENTES DE INTERES EN UNA MUESTRA. EL APARATO Y METODOS DE LA INVENCION PROPORCIONAN UN ANALOGO DE PERCEPCION DE COLOR DE LA VISION HUMANA, PREFERIBLEMENTE EN LA REGION CASI INFRARROJA, REEMPLAZANDO LOS ESPECTROFOTOMETROS Y FUENTES DE BANDA ESTRECHA UTILIZADOS EN OTROS METODOS DE DETECCION CASI INFRARROJA NO INVASIVOS. SE UTILIZAN UNA PLURALIDAD DE UNIDADES DETECTORAS CUBRIENDO CADA UNA UNA REGION AMPLIA Y SUPERPUESTA DEL ESPECTRO DETECTADO EN PARALELO A LA PERCEPCION DE COLOR Y A LA COLORIMETRIA. LAS MEJORAS CONCIERNEN PRINCIPALMENTE LA MEJORA DEL INDICE DE SEÑAL-A-FONDO (O RUIDO), DE MANERA QUE EL FLUJO DE DATOS TAMBIEN MEJORE. ESTAS MEJORAS UTILIZAN MUESTRAS CONGRUENTES, LA COMPARACION DE DISTINTOS FLUJOS DE DATOS DE DISTINTOS SEGMENTOS DE MUESTRAS DE CONJUNTOS DE FILTRO, UTILIZANDO UN SISTEMA DE INTERROGACION CON SUFICIENTE VELOCIDAD PARA PERMITIR LA PRUEBA DE SANGRE ARTERIAL, Y UTILIZANDO UN FILTRO CON UNA ESTRUCTURA ESPECTRAL. EN ALGUNAS CIRCUNSTANCIAS, SE UTILIZA UNA RED NEURAL PARA EL ANALISIS, PERMITIENDO APRENDER AL SISTEMA. TAMBIEN SE DESCRIBE UN METODO NUEVO PARA LA DISCRIMINACION DE FONDO.
