Abstract

Divers modes de réalisation concernent un appareil électronique et son procédé de fonctionnement. L'appareil électronique comprend : un boîtier pourvu d'une première plaque, d'une seconde plaque orientée dans la direction opposée à la première plaque et d'un élément de surface latéral entourant l'espace entre les première et seconde plaques ; un trou relié à l'espace ; au moins une première bobine conçue pour détecter si un appareil électronique externe devant être couplé à l'appareil électronique par l'intermédiaire du trou est couplé à l'appareil électronique ; un circuit de communication sans fil conçu pour transmettre ou recevoir des données par l'intermédiaire d'une communication sans fil ; et un processeur. Le processeur peut être paramétré pour : sortir un premier signal par l'intermédiaire de la première bobine ; vérifier si l'appareil électronique externe est couplé à l'appareil électronique selon qu'un second signal correspondant au premier signal a ou non été reçu par l'intermédiaire de la première bobine ; et commander la communication sans fil entre l'appareil électronique externe et l'appareil électronique selon que l'appareil électronique externe est ou non couplé à l'appareil électronique. Divers autres modes de réalisation sont également possibles.
