Andrew Weiner and Daniel Leaird found a way to put a single pulse of light into an arrayed wave guide grating and get a rapid-fire burst of 21 light pulses out of it, with each pulse separated by only two-trillionths of a second. It works similarly to a prism, separating white light by wavelength. The unique properties of the device allow generation of identical, wavelength-shifted pulse trains for communication and photonic signal processing. The discovery could help satisfy demand for increasing network bandwidths. The pair of Purdue University engineers say their device has transmission speeds that are ten times faster than anything currently available. "ISPs are primarily operating at 10 Gbytes/sec per channel, times very many wavelength channels," says Weiner. "Our work can impact higher speed systems, 100 Gbytes/sec per channel and above," he says. Wiener and Laird's idea is to build a module that takes parallel electric data input and converts it into a fast serial optical data stream suitable for fiber transmission.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
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.
