Abstract

La présente invention comprend un capteur capacitif sans contact permettant de détecter la vitesse de déplacement d'un utilisateur et de contrôler la vitesse de transport d'un tapis selon ladite vitesse de déplacement. L'invention permet d'améliorer le confort et la sécurité de l'utilisateur en commandant la vitesse de déplacement du tapis qui est adaptée aux conditions de déplacement de l'utilisateur. De même, un changement de la vitesse de déplacement de l'utilisateur pour chaque position de l'utilisateur est déterminé, et l'accélération du tapis est contrôlée de façon à améliorer le confort et la sécurité de l'utilisateur par un contrôle automatique de la vitesse de transport du tapis, pendant l'entraînement réalisé par l'utilisateur. Etant donné que l'utilisateur ne s'adapte pas à la vitesse du tapis mais que la vitesse du tapis peut être contrôlée selon la vitesse de l'utilisateur, l'utilisateur peut s'entraîner librement tout en contrôlant la vitesse sur le tapis roulant comme s'il était sur une piste. De même, si la vitesse de marche ou la vitesse de déplacement de l'utilisateur diminue brusquement, la vitesse du tapis peut être automatiquement diminuée, et il est donc possible d'éviter un accident, par exemple lorsque l'utilisateur trébuche ou tombe du tapis.
