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,
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
