Abstract
(EN)
An apparatus, system, and method monitors the motion, breathing, heart rate and sleep state of subjects, e.g., humans, in a convenient, non-invasive/non-contact, and low-cost fashion. More particularly, the motion, breathing, and heart rate signals are obtained through processing applied to a raw signal obtained in a non-contact fashion, typically using a radio-frequency sensor. Periods of sleep disturbed respiration, or central apnea can be detected through analysis of the respiratory signal. The mean heart rate, and derived information, such as the presence of cardiac arrhythmias can be determined from the cardiac signal. Motion estimates can be used to recognize disturbed sleep and periodic limb movements. The sleep state may be determined by applying a classifier model to the resulting streams of respiratory, cardiac and motion data. A means for display of the sleep state, respiratory, cardiac, and movement status may also be provided.

L'invention concerne un appareil, un système et un procédé de surveillance du déplacement, de la respiration, du rythme cardiaque et de l'état de sommeil de sujets, par exemple des êtres humains, de manière commode, non invasive, sans contact et peu coûteuse. Plus particulièrement, les signaux de déplacement, de respiration et de rythme cardiaque sont obtenus en appliquant un traitement à un signal brut obtenu sans contact en utilisant typiquement un détecteur à fréquence radio. Les périodes de perturbation de la respiration pendant le sommeil ou d'apnée centrale peuvent être détectées par analyse du signal de respiration. Le rythme cardiaque moyen et les informations qui en sont dérivées, par exemple la présence d'arythmies cardiaques, peuvent être déterminés à partir du signal cardiaque. On peut utiliser des estimations du déplacement pour détecter les perturbations du sommeil et du mouvement périodique des membres. L'état de sommeil peut être déterminé en utilisant un modèle de classement aux flux ainsi obtenus de données de respiration, cardiaques et de mouvement. Un moyen d'affichage de l'état de sommeil, de l'état de la respiration, du cœur et des mouvements peut être également prévu.
