    Light Touch

    Light Touch is one of the latest gadgets using light that can allow users to use any flat surface as a keyboard or screen. It uses holographic laser projection (HLP) technology to produce images in WVGA resolution. With the use of an infrared sensor, Light Touch can detect motion, which allows interaction with applications. It is Wi-Fi and Bluetooth. The device runs on Adobe Flash Lite 3.1 and has 2GB of built in Flash memory. It was designed by Light Blue Optics, a company that specializes in miniature sized projection systems for use in automotive, consumer electronics and digital signage.

    Photochemical Tissue Bonding with Green Laser Light

    Photochemical tissue bonding is a process that can seal open wounds. Since 2008, it is being researched with success at the Massachusetts General Hospital. It works by first applying a special pink dye to the wound called “Rose Bengal." A gadget then beams a green laser light on it for three minutes to seal it. The dye absorbs the light, stimulating electrons that bond with collagen to create a small seal. The result of this process allows the wound to heal with less scarring. The Air Force Office of Scientific research hopes to use this technique to help with battlefield injuries. As of 2010, the process is not widely available to the public.

    Light Peak

    Light Peak is a new technology created by Intel for faster data transfer between gadgets. It utilizes a new high speed optical cable that is said to be twice as fast as USB 3.0 with a bandwidth starting at 10 GB per second. Data is transferred by light instead of electricity. Its optical module converts electricity to light with the use of miniature lasers and photo detectors. Unlike electrical cable technology, Light Peak does not have any problems with electromagnetic interference. It is expected to become available to the public in 2011.
