Garmin's Varia Radar warns cyclists of traffic approaching from the rear

By - July 1, 2015 7 Pictures

Garmin gave hope to many a floundering tech startup's CEO earlier this year when it purchased Ikubu Ltd in the wake of a crowdfunding campaign that came up short. Though the company failed to capture the imagination of the Dragon Innovation crowdfunding community, Garmin liked the cut of Ikubu's jib, so it snapped the company up with a view to bringing its rear-facing bike radar system to market. Now, the electronics giant has unveiled the finished, more polished product dubbed Varia Radar, which also integrates with Garmin's Edge cycle computer.

Combination radio/radar imaging produces stunning view of Venus

By - March 16, 2015 2 Pictures
A team of astronomers combining radio data from the Green Bank Telescope, West Virginia, and data from the radar transmitter at the National Science Foundation's Arecibo Observatory, Puerto Rico, have compiled a stunning new view of Venus. Often described as Earth's twin due to its similar proportions, capturing high quality images of the inhospitable planet has traditionally been a challenging prospect thanks to extreme atmospheric conditions. However, by combining observations from the instruments to create a more complete picture of Venus, astronomers can begin to observe how this enigmatic celestial object evolves over time. Read More

Garmin may begin offering radar systems for bikes

Even when a crowdfunding project doesn't meet its financial goal, it can still turn out to be a success. A case in point is iKubu Ltd's Backtracker, a car-detecting low-power radar system for bicycles. Although the South African startup's fund-raising campaign on Dragon Innovation didn't work out, electronics giant Garmin has now bought the company. Read More

Mercedes-Benz unveils Blind Spot Assist technology for trucks

By - September 2, 2014 22 Pictures
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.

Review: Backtracker radar system for bikes

By - July 28, 2014 3 Pictures
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

Backtracker radar system warns cyclists of approaching cars

By - July 4, 2014 4 Pictures
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

WatchStander is made to keep the pirates at bay

By - June 2, 2014 2 Pictures
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
