Title
(EN) DEVICE SENSING AND CHARGING USING NETWORKED COILS
(FR) DÉTECTION ET CHARGEMENT DE DISPOSITIF À L'AIDE DE BOBINES EN RÉSEAU
Abstract
(EN) Sensing and charging of electronic devices using coils. A software-defined collaborative sensing approach can allow detection and location of multiple electronic devices with respect to a charging surface to allow for wireless charging thereof. Systems and methods can measure the interaction of devices with a generated magnetic field through a network of nested sensing coils that can sense the location of devices located around the network of coils based on their interaction with magnetic fields. Once the location of a device to be charged is determined, charging energy can be directed to the device based on its location on the charging surface. The charging surface can include one or more sensing nodes having a combination of nested active, or driven, and passive coils. These coils can be configured to transform existing two-dimensional (2D) surfaces or three-dimensional (3D) areas into a multi -device contactless wireless charger.
(FR) La présente invention concerne la détection et le chargement de dispositifs électroniques à l'aide de bobines. Une approche de détection collaborative définie par logiciel peut permettre la détection et la localisation de multiples dispositifs électroniques par rapport à une surface de charge pour permettre une charge sans fil de ceux-ci. Des systèmes et des procédés peuvent mesurer l'interaction de dispositifs avec un champ magnétique généré à travers un réseau de bobines de détection imbriquées qui peuvent détecter l'emplacement de dispositifs situés autour du réseau de bobines sur la base de leur interaction avec des champs magnétiques. Une fois que l'emplacement d'un dispositif à charger est déterminé, l'énergie de charge peut être dirigée vers le dispositif sur la base de son emplacement sur la surface de charge. La surface de charge peut comprendre un ou plusieurs nœuds de détection comprenant une combinaison de bobines actives ou commandées et passives imbriquées. Ces bobines peuvent être conçues pour transformer des surfaces bidimensionnelles (2D) ou des zones tridimensionnelles (3D) existantes en un chargeur sans fil sans contact pour de multiples dispositifs.
