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,
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
