Apple is always filing patents for strange and fantastic things that never seem to find their way into actual products. But an application published today details some interesting tech that we could actually see getting jammed into a future iPhone (for better or worse). By pairing an infrared sensor with the camera already on board, portable devices could receive data from transmitters placed, well, wherever. Beyond simply blasting out text and opening links like a glorified QR code, transmitters could disable certain features, such as the camera, to prevent recording at movie theaters and music venues. If completely shutting off the cam seems a bit heavy-handed, watermarks can also be applied to photos identifying businesses or copyrighted content. Some potential uses are a little less Big Brother, like museums beaming information about exhibits to a user's or launching an audio tour. Obviously third parties would have to get behind the IR push ...

The rise of tablets and smartphones has made the touchscreen a rather ubiquitous interface, but they aren't  everywhere  quite yet. A group of students from Texas A&M intend to change that, however, with the invention of ZeroTouch: a seemingly empty picture frame that lets you turn any surface into an interactive touchscreen. It might not look like much, but ZeroTouch is packing a series of pulsing LEDs and infrared sensors that turn that blank space into a highly sensitive surface. Basically, the strategically placed LEDs cover the open area in a sheet of invisible light. When a hand or stylus enters the picture (or lack there of), those beams are interrupted, providing cues to a piece of software that tracks the object's movement -- and boom! You've got a touchscreen. Of course, this isn't the sort of thing that's going to make it to market anytime soon, but you can check out ZeroTouch rocking the rippling water effect in the video below.

It might look like a poor man's game of Pong now, but a new laser steering system coming out of North Carolina State University could make blowing things up  Star Wars -style cheaper and more efficient. The setup enlists a series of "polarization gratings" through which a laser beam passes. Each of these gratings, made of liquid crystal applied to a plate of glass, are configured to redirect the light in a particular direction, thus simply steering the laser beam without significantly decreasing its power -- with each grating comes a new "steerable" angle. The system's creators point out its not only hyper accurate, but also less expensive than existing arrangements due to the use of liquid crystal. Apparently the US Air Force is already using the stuff, but don't expect them to go all Death Star anytime soon. North Carolina State University
