Abstract

L'invention concerne un système comprenant un dispositif comportant une unité fonctionnelle à commander, un tel dispositif, une unité externe à coupler à celui-ci et un procédé de commande de puissance. Afin d'obtenir une possibilité de mise à niveau du système avec une fonctionnalité supplémentaire pendant sa durée utile à de faibles coûts initiaux ou efforts du côté du dispositif comprenant l'unité fonctionnelle, l'unité externe se présente sous la forme d'une unité enfichable, qui reçoit de l'énergie du dispositif et influence une première partie de circuits d'attaque située dans le dispositif en raison de son couplage avec la seconde partie de circuits d'attaque de l'unité externe, qui peut être commandée par le dispositif de commande de l'unité externe. De cette manière, une capacité de communication du dispositif dans le sens de recevoir (ou d'envoyer) des signaux de données pour la commande du dispositif n'est pas du tout nécessaire.
