Bruce Wessels wants to increase the data transmission connection on your computer. The Northwestern University professor of material science and engineering patented a device and material for integrated optic circuits. He says his thin-film electro-optical modulator provides a faster way to transmit information. Wessels uses a metal-organic molecular beam epitaxy apparatus for the thin-film deposition. In addition to the modulators, Wessels and associate professor Seng-Tiong Ho developed wave guides and optical amplifiers using ferroelectric material. They point out that bulk crystals used in optical circuits now have limits and their thin film is superior because it enables high-speed operations with low voltage for less expense. The researchers demonstrated that their thin-film modulators work at frequencies up to 20 gigahertz. SVT Associates is working with Wessels to develop and commercialize the technology.

Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
