The level of concern over sonic boom annoyance became so significant that the Federal Aviation Administration prohibited domestic civil supersonic flight over land in 1973. This prohibition helped quiet the skies and reduce potential impacts on the environment. However, it also dashed hopes of introducing supersonic overland passenger service within U.S. airspace during the Concorde era.
Transphorm Inc. (Goleta, CA) announced 600V GaN (Gallium Nitride)-based, low-profile PQFN products and the expansion of its product portfolio in the industry-standard TO220 packages. The 600-V GaN HEMTs (high electron mobility transistors) use the

3D printing isn’t new, especially to the engineering community, but it can’t be denied that additive manufacturing has been under the marketing spotlight in the last 18 months. That’s why Luis Lopez and Clay Tweel found themselves working on an indie-documentary featuring some of the biggest “little” companies in 3D printing.
Texas Instruments introduced two flyback power solutions that are said to achieve the highest energy efficiency and lowest standby power consumption for 5-W to 100-W AC/DC power supplies. The UCC28910 switcher with integrated
A UK design firm recently unveiled the Airlander, a football field-sized airship that they hope will become the new standard for transportation for supplies. Each Airlander costs around $40 million to construct.Weighing in at 44,000 pounds, this airship uses 80 percent less fuel than airplanes and helicopters.
Hopefully this comeback is a little less explosive than the Hindenburg’s reputation. A UK design firm recently unveiled the Airlander, a football field-sized airship that they hope will become the new standard for transportation — not of passengers, but of supplies.
The U.S. government is relinquishing its control of the Internet's address system in a shift that may raise questions about the future direction of online innovation and communications. The decision announced Friday begins a long-planned transition affecting the stewardship of the Internet Corporation for Assigned Names and Numbers, or ICANN.
Under London's streets in Winston Churchill's World War II bunker, young techies are fighting a new kind of war. Bent over their computers in a steel-reinforced room, dozens of amateur cyber security experts spent Friday racing to understand why Britain's banking network suddenly seemed to have gone offline.
Hundreds of years after wealthy merchants began building the tall, narrow brick houses that have come to define Amsterdam's skyline, Dutch architects are updating the process for the 21st century: fabricating pieces of a canal house out of plastic with a giant 3-D printer and slotting them together like oversized Lego blocks.
London, like any busy city, is full of people and cars and everyone is trying to use the same roads. In order to make the systems run more efficiently, London is investing in intelligent pedestrian crossing to the tune of several billion pounds. The system, which is actually called the Pedestrian Split Cycle Offset Optimisation Technique—catchy name—or “SCOOT”...
Today on Engineering Newswire, we're 3D printing documentaries, talking toilet lights, and riding the flying phantom above the water. This episode features: Flying Phantom: Phantom International has introduced its next generation of foiling catamarans, the Flying Phantom.
Sealevel Systems, Inc. (Liberty, SC) announced the SeaRAQ family of I/O expansion boards designed for Relio R3 rackmount industrial computers. The boards interface to a variety of real-world I/O, and all boards are isolated to
Security is becoming increasingly important in a wider range of applications. Numerous methods have been developed to force systems to expose confidential information or even application code, resulting in the development of countermeasures to ensure the security of Flash and EEPROM ICs.
With around 2 billion people connected to the Internet and the advent of IoT, there may already be more connected ‘things’ than connected people. In 2013, by some estimates, there were over 10 billion connected devices, and this will climb as high as 50 billion by 2020....
Teenagers these days. They can’t go one minute without their cell phone. But apparently, neither can adults. A new study shows that one in three parents are using their cell phones almost nonstop during meal time at restaurants, and it’s probably safe to say this kind of behavior goes on at home, too.
UK Ministry of Defence recently announced a Release to Service for their own UAV, the WatchKeeper WK450, meaning that it’s been cleared for flight training. Based on the Elbit Hermes 450 UAV, the Watchkeeper WK450 is an Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR) unmanned aerial vehicle.
Mornsun has launched the IF/B_XT-1WR2, F/B_XT-2WR2, F_D-1WR2, R2 series of DC-DC converters. Compared with the old generation, they have improved on efficiency, no-load power consumption, and short-circuit protection. They also feature compact size....
