A group of researchers, led by a Carnegie Mellon University (CMU) researcher, developed a technology which recognizes determines the difference in sound when you tap of a fingertip, the pad of the finger, a fingernail or a knuckle on a touchscreen. This technology, called TapSense, enables richer touchscreen interactions by employing the anatomy and dexterity… »

Stanford researchers have developed a highly sensitive underwater microphone which is modeled after the extraordinarily acute hearing of orcas. The microphone can capture a wide range of ocean sounds in a range of approximately 160 decibels, significantly more than existing underwater microphones (hydrophones) which have limited ranges of sensitivity and do not perform well at… »

Physicists Morgan Kjølerbakken and Vibeke Jahr were working on sonar technology when they came up with the idea for what they call a super-microphone while they were at the University of Oslo, Norway. Kjølerbakken and Jahr have now patented the device, dubbed it AudioScope, and founded a company Squarehead Technology where they commercialized their idea…. »
