Yet another Apple patent has been revealed this Thursday, this time indicating the company is actively looking into wireless charging for its line of accessories. However, it seems Apple is looking to use the technology in a slightly different way than its predecessors.
Wireless charging, also known as inductive charging, has been available for years; with releases from both Palm and Google. Even so, the technology has yet to catch on in the consumer market and is far from ubiquitous.
Apples invention, entitled “Integrated inductive charging in protective cover,” at first seems like a first-party attempt to replace and outdo existing products. These components usually incorporate an induction coil and transformer that outputs power via a cord plugged into the device’s dock connector. However, at second glance, Apple’s patent filing describes something different.
Instead of sourcing power from a stationary dock, Apple’s invention uses a tablet case, or more specifically an iPad Smart Cover, to hold the inductive power transmitter. In some embodiments, an internal battery is placed within the case, therefore creating an “on-the-go” wireless charger.
