Light Touch ProjectorThis Light Blue Optics device goes far beyond its projection capabilities. Light Touch is a small computer, running Windows CE on batteries, with 2 GB or 32 GB of memory, and is capable of simultaneously projecting a virtual keyboard and a virtual touch display: an image that remains in focus at any distance. Cleaning a virtual keyboard is as simple as wiping the surface with a cloth. Holographic diffraction projection displays, like this one, remain clear even when projected onto curved surfaces. Wi-Fi and Bluetooth are included. http://lightblueoptics.com/products/light-touch/AAXA L1Psych…!! You cannot purchase the above device because Light Blue Optics wants to license their software to OEMs. However, you can buy this little $600 pico-projector, which uses the same laser projection technology to create a perfectly focused 800x600 color display. The battery lasts approximately 90 minutes. You can connect the device to a video source or store content in the 160MB internal flash memory. The package also includes a 2GB plug-in USB virtual disk. Use this device for movies, photos, audio files or even MS Office and PDF documents. http://www.aaxatech.com/products/l1_laser_pico_projector.htm To understand some of the technology behind pico laser projection, check out the links at: http://www.microvision.com/Cleankeys Exchange of harmful germs can occur wherever we touch things. Keyboards are a modern germ farm: very difficult to disinfect. Cleankeys' smooth surface requires only a quick wipe between users to remove 99% of germs. At $400 each, this keyboard is a specialty item, designed for medical environments. The keyboard includes touch-sensitive keys and a trackpad.

The city's primary motivation was not to provide free access to citizens, but to avoid otherwise expensive wiring for security and traffic cameras, not to mention new wireless smart meters in homes and businesses. In another region, a rural community (limited to dial-up service) set aside signal/channel/bandwidth white space (called a “middle mile” solution) so that schools and public spaces could create Wi-Fi hotspots -Fi. This signal was strong enough to reach long distances and hills. Spectrum Bridge has also released an iPhone app to pick up white space signals directly and over longer distances. Other devices will soon receive the same treatment. It seems that white space will sooner or later return to its original function: as a video feed, carrying TV and films, but in digital and wireless form. http://www.spectrumbridge.com/
