New Battery Made From Wood Is Environmentally Friendly

Researchers at the Universityof Tokyo's Ishikawa Oku Labhave been hard at work on a camera system that can track fast moving objects incredibly well, and the technology may change the way sports like baseball and soccer are televised. Recently, the team building the system has entered the next phase of testing: taking it outside, to see if will perform as well as ithas in a lab setting. If all goesaccording to plan, they expectit'll be ready for broadcast use in roughly two years. Demos of the tech are pretty impressive, as you can see inthe video below showing the (warning: not recommended watching for those easily prone to motion sickness). To get the ping-pong ball-centric shots, the system uses a group of lenses and two small mirrors that pan, tilt and moveso the camera itself doesn't have to. The mirrors rely on aspeedy image tracking systemthat follows movement, rather than predicting it. Swapping the camera out for a projectoralso has some interesting applications -- it can paint digital pictures on whatever its tracking. Sounds like the perfect gadget for folks who wish their table tennis balls looked like emoji.
