A prototype RADAR flashlight that can detect a human's presence through walls and doors should one day make law-enforcement officers' jobs safer. The patent-pending device uses a radar and a specialized signal processor to detect movement by discerning respiration from up to 3m away. No physical connection exists between the subject and radar. The development is part of a family of technologies that also detects heartbeat, according to Gene Greneker, a principal research scientist at the Georgia Tech Research Institute (GTRI). "Based on respiration signature alone, the flashlight allows us to detect a stationary individual behind a solid wooden door, or standing four feet behind an eight-inch block wall," Greneker explains. The device uses a narrow radar beam of about 15 to 20 degrees to detect body movement generated by breathing. E-mail email@example.com,
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
