Motorola is testing cellular telephones that have transistors made with a new gallium arsenide (GaAs) process. The transistors "grow" on silicon wafers. Wafers made from gallium arsenide are typically fragile, but a unique compliant layer that bonds to both the silicon and the gallium arsenide in the new process could alleviate that problem. Combining all components on a single chip also enhances the chip performance by eliminating the speed loss and power consumption that result from driving signals from chip to chip. "In the short term, it will lower the cost of GaAs products by allowing the use of larger, less fragile wafers," says Steve Cullen, director and principle analyst, semiconductor services, Cahners In-Stat Group. "Long term, it will enable the mixing of silicon and GaAs circuits on a single chip." Cullen notes that silicon is great for complex computational circuits such as Intel's Pentium. Motorola has filed patent applications on the process. The company's plans include licensing the technology to other companies, as well as using the technology for development of its own products.

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.
