(EN) WIRELESS POWER UTILIZATION IN A LOCAL COMPUTING ENVIRONMENT
(FR) UTILISATION DE PUISSANCE SANS FIL DANS UN ENVIRONNEMENT INFORMATIQUE LOCAL
Abstract
(EN) Various embodiments of a wirelessly powered local computing environment are described. The wireless powered local computing environment includes at least a near field magnetic resonance (NFMR) power supply arranged to wirelessly provide power to any of a number of suitably configured devices. In the described embodiments, the devices arranged to receive power wirelessly from the NFMR power supply must be located in a region known as the near field that extends no further than a distance D of a few times a characteristic size of the NFMR power supply transmission device. Typically, the distance D can be on the order of 1 meter or so.
(FR) Divers modes de réalisation d'un environnement informatique local alimenté par une liaison sans fil sont présentés. L'environnement informatique local alimenté par une liaison sans fil comprend au moins une alimentation à résonance magnétique de champ proche (NFMR) agencée pour fournir, par une liaison sans fil, une puissance à l'un quelconque d'un certain nombre de dispositifs configurés de manière appropriée. Dans les modes de réalisation présentés, les dispositifs agencés pour recevoir la puissance par une liaison sans fil de l'alimentation NFMR doivent être situés dans une région connue en tant que champ proche qui ne s'étend pas au-delà d'une distance D égale à quelques fois une taille caractéristique du dispositif de transmission d'alimentation NFMR. Généralement, la distance D peut être de l'ordre d'à peu près 1 mètre.
