New Camera Sensor Filter Allows Twice As Much Light
bugnuts writes "Nearly all modern DSLRs use a Bayer filter to determine colors, which filters red, two greens, and a blue for each block of 4 pixels. As a result of the filtering, the pixels don't receive all the light and the pixel values must be multiplied by predetermined values (which also multiplies the noise) to normalize the differences. Panasonic developed a novel method of 'filtering' which splits the light so the photons are not absorbed, but redirected to the appropriate pixel. As a result, about twice the light reaches the sensor and almost no light is lost. Instead of RGGB, each block of 4 pixels receives Cyan, White + Red, White + Blue, and Yellow, and the RGB values can be interpolated." -
Surgery-Simulating Dummy Allows Doctors To Develop Skills
techgeek0279 writes "The Cybram 001 Cybernetic Brain Artery Model simulates the functioning of the cerebral blood vessels, so doctors can practice performing actual operations on the brain. Developed through joint research by Fuyo and the Saitama Medical University International Medical Center, the life size plastic body contains a blood vessel system that runs from the groin to the cerebral artery, as well as a circulation pump and pressure control circuit used to realistically simulate blood flow and pressure in the body." -
Hitachi Demos a Stylus-Friendly Capacitive Touchscreen
dk3nn3dy writes "Hitachi Displays have developed a capacitive touchscreen which converts input from a non-conductive object into electrostatic capacitance. This enables it to be used in a diverse range of ways, such as multi-touch using several fingers, with a plastic pen for finer input, and in cold places while wearing gloves. The display is currently under development for release in the second half of 2011." -
70,000 Carats of Gemstones On a Honda
pastababa writes "At Tokyo Auto Salon 2010, a Honda Odyssey with 70,000 carats of sparkling Kyoto Opal on its entire surface is on display. Kyoto Opal is a new material, based on the same quartz grains as natural opal. By coloring Kyoto Opal artificially, a diverse range of hues can be produced. In addition, a variety of cuts can be achieved, overcoming the cracking and chipping that occur in natural opal. Kyoto Opal has been combined with Jewel Paint, a new coating technology in sheet metal coating and car customization. The result is the world's first gemstone-coated car. The Jewel Paint on the Odyssey cost about US$88,690 (not including the car itself)."
