Mercedes-Benz has developed a radar-based system that alerts the truck driver of imminent ...

Trucks today are big and getting bigger, and even with cameras and superior spatial awareness, the operators of these leviathans can never be totally aware of potential collision hazards, especially when turning. To help alleviate this problem, Daimler, the truck division of Mercedes-Benz, has introduced a radar-based system that alerts the truck driver of imminent collision danger from anywhere on the entire unobservable portion of the vehicle.  Read More

Earlier this month, we first heard about a radar system for cyclists, known as the Backtracker. In a nutshell, it emits radar pulses to the rear of the bike, then warns the rider when it detects vehicles approaching from behind. Although it's not yet commercially available, I recently had the chance to try out a pre-production review unit. It definitely shows promise, but could perhaps use one tweak.  Read More

The Backtracker's front module alerts riders via an LED display

Cycling on the highway can definitely be a risky business. If riders are distracted or have the wind in their ears, vehicles rapidly approaching from behind can be almost right on top of them before being noticed. Gadgets such as mirrors and rear-view cameras can help, although riders still have to think to check them. The Backtracker, however, uses a radar signal to automatically alert cyclists whenever a car is closing in on them.  Read More

Today's ships are equipped with radar systems that let them identify other ships from a distance, and while that works well enough for collision avoidance, those systems aren't the greatest at detecting small watercraft ... such as the low-slung skiffs often used by pirates. That's where WatchStander comes in. It's a radar system that's designed to pick out such boats, and then deter their crews before they can attack.  Read More

Despite being in orbit for less than two months, the ESA's Sentinel-1A satellite is already showing its worth in the humanitarian sphere by aiding with relief efforts in the Balkans, where flood waters are estimated to have killed dozens, leaving thousands more displaced.  Read More

This near-infrared photo shows the invisible IR LED's on the Leddar in action

Leddar, short for LED Detection and Ranging, is a new type of detection and ranging sensor that uses LEDs to detect objects and determine their distance. While the Leddar is low resolution, it is also low cost, and it may find new applications in vehicles, traffic management, robotics and safety. Read on for our hands-on review.  Read More

Palmdale, CA. General Atomics Aeronautical System, Inc. (GA-ASI), the maker of the Predator and Reaper Unmanned Aerial Vehicles (UAVs) successfully completed the first of several flight tests of a prototype Sense and Avoid (SAA) system, that allows a UAV to see and avoid other aircraft in flight.  Read More

Sometimes everything can seem to happen at once. The new game in town is active invisibility cloaks (AIC), which use electronics and antennas to generate a cloaking field to hide an object. Two types of active cloaks have just been revealed (excuse the pun). While being impressive feats of technology, such cloaks could easily be defeated in practice.  Read More

Dolphins' ability to tell the difference between fish and bubbles has inspired the creatio...

Chances are, you know that dolphins use sonar to locate and stun prey underwater. You might also know that they create "bubble nets," in which they trap fish inside a ring of air bubbles that they blow while swimming in a circle. With all those distracting bubbles suspended in the water, though, their sonar needs to work in a special way in order to pick out the fish. Scientists have copied that sonar system, to create a type of radar that could differentiate between ordinary objects and things like explosive devices.  Read More

Sniffer dogs and fiber optic cameras may soon be getting some assistance, when it comes to locating people trapped beneath debris. The Department of Homeland Security’s Science and Technology Directorate has joined forces with NASA’s Jet Propulsion Laboratory (JPL) to create a microwave radar-based system known as Finding Individuals for Disaster and Emergency Response – or FINDER. The new technology is able to detect a human heartbeat buried up to 30 feet (9 meters) under assorted rubble.  Read More
