When electronic vehicle systems fail, it’s often not the fault of microcontrollers, memories or integrated circuits. By watching for some of the following problems, designers can often boost reliability of end products, especially in automobiles.
Minimize connections. There’s a high correlation between reliability and the number of electrical connections made at an assembly plant. A dashboard with ten connections, for example, is likely to be more reliable than one with 50 connections.
Make sure wires don’t rub against sharp pieces of metal.
Ensure connections go together with an audible snap. If assemblers hear the snap, they know it’s connected.
Design in reliability at the beginning. Usually, if a car starts out reliable in its first model year, it stays that way.
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.
