Privacy advocates take note, if researchers at Georgia Institute of Technology have their way, law enforcement officials will soon detect terrorists, kidnappers, and other bad boys though walls and doors with a new radar flashlight. The radar device sends out electromagnetic energy and then detects a return signal that indicates the presence of persons based on their respiration. Results are displayed as bar graphs on a screen, which rise and fall in rhythmic response to the respiration of the person on the other side of the wall. The device works through brick, wood, plasterboard, glass, and concrete walls up to eight inches thick and at distances of up to approximately ten feet. The Georgia Institute of Technology has filed a patent for the device. For more information, contact Gene Greneker at email@example.com.
