Abstract

Dispositif d'analyse en fonction du temps du spectre de puissance d'un signal physiologique modulé par le système neurovégétatif. Ce dispositif comprend un capteur (102) servant à capter un signal physiologique modulé par le système neurovégétatif, ainsi qu'un appareil de sélection de fréquence (122) servant à sélectionner au moins une fréquence inhérente au signal. Ce dispositif comprend, de plus, un processeur d'analyse de temps-fréquence (104) à fenêtre sélective servant à déterminer le spectre de puissance du signal physiologique à l'intérieur d'une fenêtre le long du signal, pour ladite fréquence, ainsi qu'un dispositif de sortie (154) servant à fournir les informations associées au fonctionnement du système neurovégétatif, telles qu'elles sont transmises par le spectre de puissance du signal physiologique.
