Just how buoyant can a material be? In the case of a "new generation" of continuous cured and modified rubber compounds from Sentinel Products Corp., "they can outperform existing PVC/vinyl nitrile materials at a competitive price," according to Scott Smith, COO. The new elastomeric metallocene-based compounds, EMR(TM) 220FL, recently received UL recognition for personal flotation devices. They have a buoyancy rating of 60, provide softness properties similar to PVC/vinyl nitrile materials, and can be easily thermoformed into 3D parts. The compounds remain flexible at low temperatures, resist fungal and bacterial growth, and have high UV and chemical resistance. Sentinel Products Corp.: Product Code 4372
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.
