Abstract

L'invention porte sur un appareil qui dans un exemple comprend un capteur de proximité et un contrôleur. Le capteur de proximité sert à indiquer la présence d'un objet vivant à une certaine distance présélectionnée d'une prise électrique. Le contrôleur exécute une action de commande présélectionnée agissant sur le fonctionnement de la prise s'il détermine qu'un l'objet vivant se trouve à l'intérieur de ladite distance.
