Abstract
Official abstract text for this publication.
A head mounted device intended to be worn by a wearer comprising: —a battery, and —a flexible wireless power system receiver connected to the battery through at least one electrical connection mean, the flexible wireless power system receiver being arranged to receive an electromagnetic field so as to allow charging of the battery through the electrical connection means.
First claim
Opening claim text (preview).
The invention claimed is: 1. A head mounted device intended to be worn by a wearer comprising: a battery, and a flexible wireless power system receiver connected to the battery through at least one electrical connection, the flexible wireless power system receiver being arranged to receive an electromagnetic field from a wireless power system transmitter to allow charging of the battery through the electrical connection, wherein the flexible wireless power system receiver is arrangeable between a deployed position in which the receiver effectively receives an electromagnetic field to allow charging of the battery and a stored position in which the wireless power system receiver has a reduced overall size to reduce the dimension of the head mounted device. 2. The head mounted device according to claim 1 , wherein the wireless power system receiver is configured for inductive coupling. 3. The head mounted device according to claim 2 , wherein the wireless power system receiver comprises at least a spring inductive coil and/or a rollable inductive coil and/or a foldable inductive coil. 4. The head mounted device according to claim 1 , wherein the head mounted device comprises at least an optical lens mounted and the wireless power system receiver is arranged in the optical lens. 5. A method for charging the battery of a head mounted device wearable by a wearer, the head mounted device including: a battery, and a flexible wireless power system receiver connected to the battery through at least one electrical connection, the flexible wireless power system receiver being arranged to receive an electromagnetic field to allow charging of the battery through the electrical connection, wherein the flexible wireless power system receiver is arrangeable between a deployed position in which the receiver effectively receives an electromagnetic field to allow charging of the battery and a stored position in which the wireless power system receiver has a reduced overall size to reduce the dimension of the head mounted device, the method comprising: positioning the head mounted device at a charging distance from a wireless power system transmitter device comprising a power source and a transmitter configured to convert the power provided by the power source to a time-varying electromagnetic field; and receiving, at the flexible wireless power system receiver of the head mounted device, an electromagnetic field from a wireless power system transmitter. 6. The method according to claim 5 , wherein the charging distance is smaller than or equal to the larger diameter of the flexible wireless power system receiver.
