Abstract: A method of charging a device wirelessly with a wireless charger begins after the device is located adjacent to the wireless charger. The wireless charger receives or determines a position of an induction coil of the device. The wireless charger then determines a position which can be reached by a charging coil of the wireless charger that will provide most efficient power transfer to the induction coil of the device. The charging coil of the wireless charger is then moved to this reachable position, and the device is charged wirelessly using the charging coil. A suitable wireless charger and an appropriately configured chargeable device are also described.

Abstract: A method to be carried out at an electronic device for detecting proximity to another electronic device is described. The electronic devices are capable of interaction through both low-accuracy sensing and high accuracy sensing. Low-accuracy sensing is used until a potential proximity event is detected. High-accuracy sensing is then activated, and attempts are made using high-accuracy sensing to detect a further potential proximity event corresponding to the potential proximity event. A determination is then made as to whether a proximity event has taken place—this is done using the further potential proximity event if detected, and using the potential proximity event otherwise. A suitable electronic device is also described, as is a method of training electronic devices to detect proximity to other electronic devices using a proximity estimation algorithm.
