Abstract

L'invention concerne un procédé selon lequel collectivement, le(s) signal/signaux électrique(s) et le(s) signal/signaux associé(s) à la force générés par des capteurs du dispositif est/sont traité(s) par un sous-système informatique avec des circuits électroniques et une architecture configurés pour la fusion de capteurs et l'extraction de caractéristiques composites indicatives d'états de santé cardiovasculaire. Selon au moins un mode de réalisation, le dispositif génère des signaux d'électrocardiogramme (ECG), des signaux de pléthysmogramme d'impédance (IPG), des signaux de ballistocardiogramme (BCG), et des mesures de poids à travers une interface avec les pieds d'un utilisateur. Des composants de sous-système informatique fusionnent les données ECG, IPG et BCG pour générer efficacement des analyses de santé cardiovasculaire de l'utilisateur, par rapport à divers paramètres associés à des composantes temporelles de phases cardiaques, de paramètres associés à la force et au volume, et d'autres paramètres pertinents. Les paramètres sont régulièrement collectés et analysés pour surveiller la santé cardiovasculaire de l'utilisateur et déclencher des interventions de santé préventive.
