Abstract

L'invention concerne un dispositif d'entretien de vêtement (100) comprenant un capteur (101) permettant de générer un signal de sortie caractérisant un mouvement dudit dispositif d'entretien de vêtement. Le capteur (101) est un accéléromètre. L'unité de commande (102) est couplée au capteur (101). L'unité de commande (102) est conçue pour identifier et comparer des caractéristiques dudit signal de sortie à des caractéristiques d'un modèle de déplacement prédéfini. Le modèle de déplacement prédéfini correspond à la quantité d'un déplacement linéaire le long d'une direction donnée du dispositif d'entretien de vêtement. L'unité de commande (102) est conçue pour ajuster au moins un paramètre de fonctionnement du dispositif d'entretien de vêtement sur la base du résultat de la comparaison entre des caractéristiques dudit signal de sortie et des caractéristiques dudit modèle de déplacement prédéfini.
