DNP Microsoft earns patent for claimed wireless charging improvement and pad with info screen

Device makers are bent on bringing us inductive charging, and Redmond has joined the fray with a recently allotted patent that describes all kinds of tech that could make it work better. For the charging itself, a trick is proposed that's similar to one we've seen before -- careful matching of the resonant frequency of charger and device. That would amplify efficiency and allow more than one device to be charged at a time. To make it easier to use, a pressure sensor could detect if a device was on the pad, with different parts of the pad allocated for smartphones or tablets, for instance. The patent also proposes a display placed opposite the charger to give it another use when it's not juicing, which would be determined by a gyro to sense which side was facing up. Of course, a lot of patents are whimsical things, which never amount to anything -- but judging by the detail in this one, Microsoft may have something more concrete in mind.
