Abstract

L'invention concerne un dispositif induisant le sommeil et un système de gestion du sommeil comprenant le dispositif. Le dispositif induisant le sommeil comprend : une unité-logement qui comprend un cadre dont la forme peut être modifiée ; une unité de détection qui est disposée sur une surface de l'unité-logement et qui comprend un capteur de mesure d'ondes cérébrales qui mesure les ondes cérébrales d'un utilisateur ; une unité d'émission qui comprend une première unité d'émission et une seconde unité d'émission, dans lequel la première unité d'émission est située sur un côté de l'unité-logement pour émettre un son ou une source de lumière d'une première fréquence, et la deuxième unité de sortie est située sur un côté opposé de l'unité-logement pour émettre un son ou une source de lumière d'une deuxième fréquence qui est différente de la première fréquence ; et une unité de commande qui calcule le schéma de sommeil de l'utilisateur en fonction du signal d'onde cérébrale mesurée par l'unité de détection et qui modifie le signal d'émission de l'unité d'émission de telle sorte que le schéma de sommeil s'approche d'une valeur prédéterminée.
