Several Apple patents have surfaced that hint towards possible iPhone hardware updates. One patent reveals an integrated AM/FM radio tuner that would make conventional broadcast radio listening possible. Not only this, but the app design includes a radio map showing nearby radio stations and the associated musical genres.

Satellite radio is also mentioned in the patent application, as well as a radio tuner card for desktop Mac computers. The app design includes presets and a similar interface to current broadband streaming radio players.

Every time a new Apple patent goes public it sets off waves of speculation about the next iPhone. The latest round of patents is no different, and some features are already expected to debut on the iPhone 5 next summer. Two of these patents would make for some interesting changes in the next iPhone and beyond.

One patent shows a redirecting flash. Apple just added an LED flash to the iPhone 4 and the company is already looking to improve this feature. A redirecting flash would be capable of aiming and focusing light to specific areas in a photograph to help properly expose the scene.

A patent application filed by Apple in August 2008 shows some novel ways to interact with the iPhone. Swiping over the camera lens and a series of taps on the back of the iPhone are described as a way to control voicemail playback while the iPhone is against the head.

Holding the iPhone in the hand would make the camera lens react differently, controlling calling options or scrolling through contacts lists or web pages. Taps would be detected through an accelerometer inside the device.

We reported earlier on the Novothink solar iPhone charger, the first device of its kind to be approved by Apple. Someday you may not even need an external case to charge your Apple device in the sun.

Apple has filed patents involving integrated solar charging panels built into future mobile devices and media players. According to the patent, energy-producing panels could be placed directly under touch screen surfaces such as an iPhone display.

With descriptions of the upcoming Apple tablet's user interface featuring words like "awesome" and "surprising" it's possible some patents filed by the company have been used in the device.

Plans for a tactile feedback virtual keyboard describe buttons and frames that would pop up when keys are displayed and retract under the surface at other times. This would make typing on an on-screen tablet keyboard feel much more like typing on a standard keyboard.
