Apple applies for patent of wireless charging system

Apple Inc. has applied for a patent of wireless charging system with the title of “Wireless power utilization in a local computing environment“. Now sooner it will be a reality to charge an iOS device, wirelessly, from a computer system by simply placing it closer to it.

In this case, “midrange wireless power transfer physics” will work i.e. near field magnetic resonance (NFMR) will help to charge the devices within 1 meter of the power base. Now to charge an iPhone or iPad or iPod, it will not be necessary to have a charger with you but necessary is to be near to a source of NFMR for charging your device.

Historically, a very limited applications have found wireless transfer of power.

In this system, wireless power source and receiver are inductively coupled by way of a magnetic field that can tangle up both the power source and receiver.
