A research group at the McCormick School of Engineering and Applied Science at Northwestern University has developed a way of using your computer's microphone and speakers, and echolocation (sonar) to determine whether you're in front of your computer or away and automatically turn off your monitor at the appropriate time to reduce power consumption. The researchers are looking for test subjects to try it out and see just how much power this system saves.
