The U.S. Patent and Trademark Office officially published a series of 80 newly granted patents for Apple Inc. today. In this particular report we cover Apple's granted patent 9,601,933 which covers their invention relating to inductive power transmission, and more specifically to tessellated inductive power transmission coil configurations capable of charging multiple devices utilizing complex areas. Apple's iPhone 8/anniversary iPhone will be Apple's first iPhone offering wireless charging. Whether this is the wireless charging pad of choice to arise this fall is unknown at this time. You could check out Apple's other Wireless Charging patents here. My favorite system thus far is one that will actually levitate your iPhone while charging it.
According to Apple, each of the square coil elements may be operable to inductively transmit and/or receive power independently. Each triangular coil element may be operable to detect the proximity of one or more inductive coils of one or more electronic devices and inductively transmit power upon such detection.
Each rectangular coil element may be operable to inductively transmit power at different frequencies, power levels, and/or other inductive power transmission characteristics and may be capable of adjusting transmission to the requirements of one or more receiving devices.
Multiple of the triangular coil elements may be operable to inductively transmit power at the same time and/or at the same time that other triangular coil elements are inductively receiving power. In cases where two triangular coil elements are inductively transmitting power at the same time, each may transmit at different frequencies, power levels, and so on.
