NASA engineers have completed tests on a device that opens the path for development of "all-electric" aircraft. Called the Electro-Hydrostatic Actuator, the device eliminates or minimizes airborne dependence on hydraulic, pneumatic, and mechanical systems. NASA tested the device on the left aileron of its F/A-18 Systems Research Aircraft without using the plane's central hydraulics. Taking its signals from the aircraft's flight-control computers, the device uses its electronics to trick aircraft computers into thinking a standard actuator is on board. Although the device contains a small amount of hydraulic fluid, it uses an electric motor to drive its pump. The force created moves the aileron. For many years, NASA, the Air Force, and the Navy have sought to eliminate heavy hydraulic systems in aircraft in favor of electrical "power-by-wire" systems for operating flight controls. The new device results from the Electrically Powered Actuation Design program of the Air Force.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
