The Air Force Research Laboratory is developing a high-temperature, high-performance dielectric film for the aircraft capacitors. Capacitors are devices that store electrical charges. The new film, called Fluorene Poly Ester, is suitable for applications from -55 to 227C. Aircraft capacitors are the weakest link in an aircraft's power electronics system because of their limited operating temperature, according to Sandra Fries-Carr, one of two developers of the film at the Air Force Research Laboratory. The laboratory formed a partnership with Wright Technology Network for developing the film for capacitor manufacturers. Initial applications include military aircraft projects.

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.
