Abstract

L'invention concerne un dispositif d'habillage (300) pour un appareil, comprenant : - un support (102), prévu pour équiper ledit appareil, et muni d'électrodes de mesure capacitive (108) ; - un revêtement (104), recouvrant ledit support (102), et comprenant une multitude d'éléments d'habillage (106), souples, faisant sailli dudit support (102) ; et - une électronique de détection capacitive (110) configurée pour : ▪polariser au moins une électrode de mesure (108) à un potentiel alternatif de détection (VG), différent d'un potentiel de masse, à une fréquence de détection, et ▪détecter un signal de détection capacitive provenant d'au moins une électrode de mesure (108) ; de sorte à détecter qu'un objet touche, ou s'enfonce dans, ledit revêtement (104), et avant que ledit objet entre en contact avec ledit support (102).The invention relates to a covering device (300) for an appliance, comprising: - a support (102), provided to equip said appliance, and provided with capacitive measurement electrodes (108); - a coating (104), covering said support (102), and comprising a multitude of covering elements (106), flexible, projecting from said support (102); and - a capacitive detection electronics (110) configured to: ▪polarize at least one measuring electrode (108) to an alternating detection potential (VG), different from a ground potential, at a detection frequency, and ▪ detecting a capacitive sense signal from at least one measuring electrode (108); so as to detect that an object touches, or sinks into, said coating (104), and before said object comes into contact with said support (102).
