Abstract:
A technique for charging a wireless device includes detecting a physical presence of a user with respect to the device. A magnetic force is provided between a charging pad and the device only when the physical presence of the user, with respect to the device, is not detected. In this case, a rechargeable power source of the device receives a charging current from the charging pad via conductive contacts of the device.
