These guides are used for backlighting displays in a number of applications from digital still camera and camcorder microdisplays to Gen 3 mobile phone displays to desktop monitors. Brighter than other LED-based backlighting systems, they come in sizes from 0.24-inch diagonal to 15.4-inch diagonal, in single LED monochrome, bi-color or tri-color backlights. The MicroLens pixel-based light extraction technology makes the LEDs brighter, crisper, and as thin as 0.60 mm or smaller. They only consume about 1-20 mA @ 3.5V, and are about 80-85 percent uniform on average. Mechanical holding features can either be built into the backlight or onto a custom-designed backlight frame. Prices vary, but simple single-LED backlights can cost as little as $1 or less in quantity.
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.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
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.
