Title (EN) WIRELESSLY CHARGED DEVICES
(FR) DISPOSITIFS CHARGÉS SANS FIL
Abstract:
(EN) This disclosure relates to the inductive charging of portable electronic devices. In particular, a charging assembly is disclosed that allows a portable electronic device to be charged in multiple orientations with respect to a charging device. The charging assembly includes two or more separate inductive receiving coils. The inductive receiving coils can be arranged orthogonally with respect to one another by wrapping one or more secondary receiving coils around a primary receiving coil. By orienting the receiving coils orthogonally with respect to one another, the likelihood of at least one of the receiving coils being aligned with a charging field emitted by a charging device increases substantially.
(FR) La présente invention concerne la charge inductive de dispositifs électroniques portables. En particulier, l'invention concerne un ensemble de charge qui permet à un dispositif électronique portable d'être chargé dans de multiples orientations par rapport à un dispositif de charge. L'ensemble de charge comprend deux bobines de réception inductives distinctes ou plus. Les bobines de réception inductives peuvent être disposées de manière orthogonale l'une par rapport à l'autre en enveloppant une ou plusieurs bobines de réception secondaires autour d'une bobine de réception primaire. En orientant les bobines de réception orthogonalement l'une par rapport à l'autre, la probabilité qu'au moins une des bobines de réception soit alignée avec un champ de charge émis par un dispositif de charge augmente sensiblement.
