The patents include one for a proximity sensor for the iPhone and iPad and another for haptic feedback to create a sort of virtual keyboard.
The patents, approved by the U.S. Patent and Trademark Office, cover a wide range of technologies, as earlier reported by Patently Apple. The proximity sensor patent, first filed in 2005, covers technology related to detecting one or more touches and differentiating whether the touches are light or hard, among other capabilities.

And Apple also was granted a patent for a mounted shock sensor that allows an Apple Store Genius or technician to figure out whether a damaged device was dropped.
