Infrared Search And Track Systems And The Future Of The US Fighter Force

Lockheed has a new modular sensor system for combat aircraft dubbed the "Legion Pod" that aims at plugging a major hole in US air warfare capability. It provides a bolt-on Infrared Search and Track (IRST) system for optically hunting down enemy aircraft, especially stealthy ones, that our radars have trouble detecting. » 3/26/15 3:31pm 3/26/15 3:31pm

How This Bug-Inspired Compound Eye Could Transform Missile Seeker Tech

The USAF is working on a fly-like artificial compound eye that could one day be used for seekers on missiles as well as other targeting systems. This is hardly the first time the DoD has looked to mother nature for good ideas, but compound eye technology has the potential to greatly increase the field of view and… » 3/11/15 1:46pm 3/11/15 1:46pm

Turn Your Valuables Into a Mesh Network So You Never Lose Them

Losing things is a pain, partly because you spend so much time looking for them. A new technology called Pixie is trying to solve that problem, and even make tracking down your misplaced valuables kinda fun, by turning them into a connected network you can search with an augmented reality interface. » 2/03/15 9:00am 2/03/15 9:00am

This Cheap Sensor Will Tell Your Phone When Food Goes Bad

Some MIT eggheads invented a very impressive and very inexpensive sensor that stands to protect you against anything from a bomb to a bad pack of beef. And it's so simple. The new sensor is just a modified near field communication (NFC) chip that can detect the presence of specific gases with the help of carbon… » 12/08/14 5:30pm 12/08/14 5:30pm

How a Medical Stress Sensor Evolved Into a Beautiful Wearable For All

Seven years ago, an MIT professor named Rosalind Picard developed a wristband called iCalm to help autistic kids manage stress by measuring electrodermal activity on the skin. Today, Picard and her team want to put their device in your hands. What happened in between is a fascinating story about the role of accidental… » 11/19/14 2:03pm 11/19/14 2:03pm

Zurich Installed 4,500 Street Sensors to Count Every Car in the City

Congestion pricing—the implementation of high tolls to keep cars out of congested downtown areas—is one of the most effective ways to reduce traffic and emissions. Zurich's plan goes above and beyond that, using a network of sensors to track the number of cars that enter its downtown and prevent more cars from… » 10/16/14 3:41pm 10/16/14 3:41pm

Human-Sensing Fan Only Blows Where There Be People

Nothing puts a strain on your local power grid like a hot, humid summer day. In many cities rolling blackouts are needed to cope with the strain, so it makes sense that companies would start developing smarter cooling devices. Quirky's Aros air conditioner is leading the charge, but this smarter oscillating fan is… » 5/16/14 4:20pm 5/16/14 4:20pm
