Working under contract with the Oak Ridge National Laboratory, Bob Englar and other researchers at the Georgia Institute of Technology are helping reduce the aerodynamic drag on tractor-trailer truck by at least 35%. Englar's work involves a pneumatic systems called Circulation Control that creates lift on the trailer by blowing compressed air over curved surfaces on the trailer, smoothing airflow and decreasing drag. He also found that blowing air from the bottom of the truck has the opposite effect, multiplying downward force on the tires to improve traction and braking when needed. The system uses valves that respond to driver changes in a fraction of a second, augmenting force as needed. "The driver wouldn't have to think about how it works," says Englar. He estimates that, if applied to the entire U.S. fleet of tractor-trailers, the pneumatic system could save 1.2 billion gallons of fuel each year.

Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
The enhanced ST8 includes new functionality designed to help users accelerate design speed and improve the user’s ability to leverage synchronous technology. The update offers greater flexibility in choice of platform and purchasing options, according to the company.
“How can European standards affect me, especially since I only use machines built in the US?” This is a common question, and one way to answer this is to look at how machine safety is enforced, where the information comes from, and how well you can prove you followed the regulations.
