Title (EN) MAGNETIC SHIELD FOR USE IN A LOCATION SENSING SYSTEM
(FR) ECRAN MAGNÉTIQUE DESTINÉ À SERVIR DANS UN SYSTÈME DE DÉTECTION DE LOCALISATION
Abstract:
(EN) An energy transfer apparatus with a magnetic shield is configured to magnetically couple energy from a fixed location to a mobile or moveable device within a field-activated space of the energy transfer apparatus. Apparatuses include a location sensing surface and a drive coil arranged in relation to a periphery of the location sensing surface. A magnetic shield plate is disposed below the location sensing surface and the drive coil. The shield plate includes a number of radially oriented slots originating at, and distributed about, a periphery of the shield plate.
(FR) Un appareil de transfert d'énergie équipé d'un écran magnétique est configuré pour coupler magnétiquement l'énergie provenant d'un emplacement fixe à un dispositif mobile ou déplaçable à l'intérieur d'un espace activé par un champ de l'appareil de transfert d'énergie. Les appareils comprennent une surface de détection d'emplacement et une bobine d'excitation positionnée en relation avec une périphérie de la surface de détection d'emplacement. Une plaque d'écran magnétique est disposée sous la surface de détection d'emplacement et la bobine d'excitation. La plaque d'écran comporte un certain nombre de fentes orientées radialement partant d'une périphérie de la plaque d'écran et réparties autour de ladite périphérie.
