Among 27 new patents granted to Apple today is an interesting wireless charging dock concept reviewed by Patently Apple. Basically, an inductive charging circuit makes the dock capable of charging an iPhone or other mobile device without a connector. The dock itself would be linked to a power source.
Just resting a compatible iPhone on the dock would initiate charging, while a reradiating antenna inside the dock would enhance the strength of nearby Wi-Fi signals. Presumably this wireless data connection would be used to sync the device while charging. Current iPhone models are already capable of automatic syncing while plugged into a power source.
