Pressure-sensing GravitySpace floor adds new dimension to the smart home

By - January 27, 2013 4 Pictures
Smart floors could soon be part of our smart homes. Scientists in Germany have developed a high-resolution pressure-sensitive floor that can accurately keep track of people and furniture in rooms. Dubbed "Gravity Space," the floor can detect poses, movements and collisions and create a mirror-like inverse projection of the goings-on above. The technology could have a wide range of applications ranging from home security and automation to interactive gaming. Read More

Asahi's auto glass blocks UV, filters out IR rays

As prolonged exposure to sunlight increasingly becomes a health hazard, causing skin problems and even cancer, automakers have started to incorporate glass that blocks harmful ultraviolet light. Japan's Asahi Glass Co (AGC) has added to its portfolio a new line of tempered front window glass called UV Verre Premium Cool on, which it says is the first of its kind to block about 99 percent of ultraviolet radiation, along with infrared (IR) rays.

Perfect optical absorber invented at Harvard University

By - December 7, 2012 5 Pictures
Harvard Professor of Applied Physics Federico Capasso and his collaborators have invented a nearly perfect optical absorber. By coating a piece of sapphire with an exceedingly thin (180 nm) layer of vanadium dioxide (VO2), a surface is created that absorbs 99.75 percent of infrared light with a wavelength of 11.6 micron wavelength. Such optical absorbers can be tailored to enable a wide range of applications. Read More

A 12-eyed music creator: the Dodecaudion music controller

By - November 13, 2012 9 Pictures
Moving around the stage while performing is a whole lot easier with instruments such as the Vortex or Kitara than with something like the mighty JUPITER-80. Innovations like Onyx Ashanti's Beatjazz hands or the Air Piano from Omer Yosha go even further, by making movement a vital part of the music creation process. Such is the case with the Dodecaudion from Polish art and design group panGenerator. When a performer places a hand, foot, head or other part of the body in front of any of its 12 IR-sensor-packing faces, wirelessly-linked processing hardware generates pre-programmed audio or visuals.

Spitzer space telescope observations reveal expansion rate of the Universe

The size and age of our Universe is not only a critically important issue in cosmology, but is also among the most controversial and delicate of the cosmological questions. Infrared observations made using NASA's Spitzer Space Telescope have now given us the most precise estimate yet of the rate at which our Universe is expanding. The key was not the discovery of a new method for measuring distance. Rather, astronomers discovered how to measure brightness more accurately. The new value for the Hubble constant, good to within three percent, is 74.3 kilometers per second per megaparsec (km/s/Mpc). Read More

Black silicon could boost efficiency of traditional solar cells

By - October 3, 2012 2 Pictures
Researchers at the Fraunhofer Institute for Telecommunications have developed a system that allows solar cells to effectively harvest energy from the infrared spectrum, tapping into a source of energy that in the past has mostly been out of reach. The new technology, which promises to work well with commercially available solar cells, has the potential of becoming a standard in the solar panels of tomorrow. Read More
