STMicroelectronics introduced the first MDmesh V Super-Junction MOSFET featuring a new package technology that increases the efficiency of power circuitry in equipment such as white goods, televisions, PCs, telecom, and server switched-mode power supplies. The new TO247-4 4-lead package
Alone in the single-seat cockpit and high above the American Southwest, pilot Bertrand Piccard could hear only his plane's gear box and the quiet whine of four electric motors. No noisy jet engines. He's flying Solar Impulse, considered the world's most advanced sun-powered plane.
An experimental, unmanned aircraft developed for the U.S. Air Force went hypersonic during a test off the Southern California coast, traveling at more than 3,000 mph, the Air Force said Friday. The X-51A WaveRider flew for more than three minutes under power from its exotic scramjet engine and hit a speed of Mach 5.1, or more than five times the speed of sound.
Samsung Electronics Co. says the U.S. Department of Defense has approved using Samsung smartphones for its networks. The South Korean company said Friday the Galaxy S4 smartphone has become the first Android device to meet the security requirements set out by the U.S. government...
Technology created an energy revolution over the past decade - just not the one we expected. By now, cars were supposed to be running on fuel made from plant waste or algae - or powered by hydrogen or cheap batteries that burned nothing at all.
With 160 confirmed kills, Chris Kyle is one of the most prolific snipers in American history. The best-selling author of American Sniper was recently killed on a shooting range by a fellow vet, and Kyle's wife graciously donated his sniper rifle to NVision for them to scan for a project.
A Rice University laboratory's cagey strategy turns negatively charged carbon nanotubes into liquid crystals that could enhance the creation of fibers and films. The latest step toward making macro materials out of microscopic nanotubes depends on cage-like crown ethers that capture potassium cations.
Double-amputee Jason Koger used to fly hundreds of miles to visit a clinician when he wanted to adjust the grips on his bionic hands. Now, he's got an app. Koger came to Philadelphia this week to demonstrate the i-limb ultra revolution, a prosthetic developed by the British firm Touch Bionics.
A groundbreaking new initiative led by the University of York, with partners at Cass Business School, part of City University London and Durham University Business School, aims to unlock the potential for scientific and social benefits in digital games.
AutomationDirect’s ultrasonic sensor offering now includes additional 18mm and 30mm round plastic DC models available with discrete or analog outputs. The sensors are equipped with LED status indicators and a push-button teach feature for configuration of normally-open
Determined to kill or capture a murderous Mekong River drug lord, China's security forces considered a tactic they'd never tried before: calling a drone strike on his remote hideaway deep in the hills of Myanmar. New light has been cast on China's unmanned aerial vehicle program, which has been quietly percolating for years and now appears to be moving into overdrive.
In the very early hours of the morning, in a Harvard robotics laboratory last summer, an insect took flight. Half the size of a paperclip, weighing less than a tenth of a gram, it leapt a few inches, hovered for a moment on fragile, flapping wings, and then sped along a preset route through the air.
A new semiconductor device capable of emitting two distinct colours has been created by a group of researchers in the US, potentially opening up the possibility of using light emitting diodes (LEDs) universally for cheap and efficient lighting.
Though people often refer to the toilet as “the throne,” the euphemism has never been taken quite this literally before. Kohler, the family-owned bath and kitchen company and inventor of all around fancy bathroom fixtures, has really gone all out with their newest creation, Numi.
In a repetition of an experiment I have posted about here on the Curious Cat Science and Engineering Blog before (Letting Children Learn – Hole in the Wall Computers): Given Tablets but No Teachers, Ethiopian Children Teach Themselves The experiment … Continue reading →
NASA's newest scientific rover is set for testing May 3 through June 8 in the highest part of Greenland. The robot known as GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, will roam the frigid landscape collecting measurements...
When people create and modify their virtual reality avatars, the hardships faced by their alter egos can influence how they perceive virtual environments, according to researchers.A group of students who saw that a backpack was attached to an avatar that they had created overestimated the heights of virtual hills...
Asbestos was once called a miracle material because of its toughness and fire-resistant properties. It was used as insulation, incorporated into cement and even woven into firemen's protective clothing. Over time, however, scientists pinned the cause of lung cancers such as mesothelioma on asbestos fiber inhalation.
Choosing the right power supply design is imperative for an overall successful product. With the ongoing goal of increased density, reliability, and efficiencies, power ratings need to be reviewed carefully. Product life, temperature, input voltage, load, and cooling are vital considerations,
Cal Sensors announced an optical detector technology capable of detecting muzzle flash from over 100 meters away, while minimizing false alarms. Operating at the speed of light, an optical flash detection system provides an almost instantaneous response to a gunfire event, providing
YouTube vs. TV? YouTube says the battle - if there ever was one - is over. In a flashy presentation to advertisers Wednesday night, Google Executive Chairman Eric Schmidt declined to forecast that Internet video will displace television watching. Instead he declared: "That's already happened."
It's not a "Star Trek" tricorder, but by hooking a variety of gadgets onto a smartphone you could almost get a complete physical - without the paper gown or even a visit to the doctor's office. Blood pressure? Just plug the arm cuff into the phone for a quick reading.
Police and politicians across the U.S. are pointing to the example of surveillance video that was used to help identify the Boston Marathon bombing suspects as a reason to get more electronic eyes on their streets. From Los Angeles to Philadelphia, efforts include trying to gain police access to cameras used to monitor traffic,
The French government has defended its veto over Yahoo Inc.'s attempted takeover of video sharing website Dailymotion, even as the move draws jeers for discouraging much needed foreign investment. Yahoo this week abandoned plans to take a 75 percent stake in Dailymotion, a deal sought by the managements of both companies, after the government blocked it.
Among the procedures Army surgeon Hawkeye Pierce performed on "M.A.S.H." was an end-to-end anastomosis. Most of the viewers, actor Alan Alda concedes, had no idea he was talking about removing a damaged piece of intestine and reconnecting the healthy pieces.
