20140266026 | Mobile Charging Unit for Input Devices - Devices, methods, and systems for charging input devices. A charging unit includes a sleeve for receiving a stylus and a base. The charging unit receives electrical power from an external power source via an interface and transfers the power to the stylus via a connection between the base's charging contacts and conductive charging zones on a portion of the input device in the base. A method detects insertion of a stylus into a charging unit having an internal battery and an interface capable of receiving power from an external power source. The method determines if the unit is connected to a power source. If so, the stylus is charged by transferring the received energy via a connection between the unit's charging contacts and conductive charging zones of the stylus. If energy is not being received from the external power source, the method charges the stylus using the unit's internal battery. | 09-18-2014 |
