Covers solar charging, multi-touch, other tech
Apple has won 16 new patents through the US Patent and Trademark Office, says Patently Apple. These cover a variety of different fields, one notable example however being Switched Capacitor Projection Scan Multi-Touch Sensor Array. The document describes technology needed to build touch sensors into a single surface of a touch substrate, a design concept essential to Apple's handhelds.
Others describe things like camera functions and the iPhone 3G dock. One reinforces Apple's recurring interest in solar power. By building solar panels into mobile devices Apple could significantly improve the battery life of its devices; the common expectation is that Apple may eventually build solar cells into its displays, making them inconspicuous while retaining structural integrity.
