Advanced inductive charging pad for portable devices

摘要

Systems and methodologies for efficient inductive charging of electronic devices are provided herein. A charging device as described herein can utilize a sensor-integrated resonating circuit with automatic frequency control to provide low-cost inductive charging functionality for electronic devices. As further described herein, a device to be charged can be equipped with a power receiver operable to receive power from the charging device via electromagnetic induction. The power receiver can additionally be utilized for initiation of charging such that charging for a device commences upon its associated power receiver being brought within range of an inductive charging surface at the charging device. Further, a charging device as described herein can have an inductive charging surface as well as a non-charging surface for providing other services such as information display. A charging device can integrate with an external information source to obtain items to be displayed at a non-charging surface thereon.
