Abstract

UN MEDIDOR DE OXIGENO PULSATORIO INCLUYE DOS LUCES (62,64) PROCEDENTES DE DOS DIODOS DE EMISION. CADA LED SE ACTIVA POR UNA SEÑAL DE MODULACION UNICA. LA LUZ PRODUCIDA POR LOS LEDS PASA A TRAVES DEL TISU DE UN SUJETO Y SE DETECTA MEDIANTE UN FOTODIODO (60). LA SEÑAL DEL FOTODIODO SE SEPARA MEDIANTE CIRCUITOS REGLADOS (72,74) RESONANTES EN DOS FRECUENCIAS DE SEÑAL DE MODULACION Y SEÑALES DE INFORMACION FISIOLOGICA QUE SE RECONVIERTEN DESDE LAS SEÑALES SEPARADAS POR LA DEMODULACION DE AMPLITUD (100,102). LA DISPOSICION DEL INVENTO DISPONE DE LA IDENTIFICACION DE LOS LEDS COECTADOS ESPALDA CONTRA ESPALDA Y DE UNA BANDA ESTRECHA QUE FILTRA EL RUIDO.
