Abstract

Système de détection comportant un appareil de détection et un composant pouvant être détecté par cet appareil. Le composant (3) détectable comprend un élément magnétique (4) mobile par rapport à l'appareil de détection, et l'appareil de détection comprend : un oscillateur (10) pour produire un signal d'oscillation ; un composant de détection (20) couplé en vue de recevoir le signal d'oscillation, ce composant présentant une impédance qui varie en fonction du champ magnétique lorsque le signal d'oscillation est transmis au composant de détection ; un capteur (21, 22', 23, 24, 25, 26, 27, 31) pour détecter une variation de l'impédance du composant de détection (20) ; et un dispositif de sortie (34) pour produire un signal de sortie dépendant de la variation de l'impédance détectée par le capteur, et qui résulte du déplacement de l'élément magnétique (4) par rapport à l'appareil de détection. Ce système de détection peut être un jouet ou un jeu, ou constituer une partie de celui-ci.
