DuPont of Wilmington, DE, spent 15 years developing a new category of bio-based materials called DuPont Renewably Sourced Materials. The company launched a Web portal at renewable.dupont.com to make it easy for design engineers to find and learn about these materials. In addition to basic product information, the website provides environmental data sheets for each product family. These sheets disclose information on the products’ cradle-to-grave environmental footprint, including an analysis of greenhouse gas emissions and non-renewable energy consumption.
DuPont’s renewably sourced materials are high-performance, bio-based materials and biofuels made in whole or in part from renewable agricultural feedstocks such as corn, soybeans, sugar cane and wheat rather than petroleum. In the future, DuPont expects to make these materials from cellulosic feedstocks from fast-growing energy crops such as grasses and agricultural byproducts like corn stalks. There are two criteria DuPont uses to select renewably sourced materials. First, they must contain at least 20 percent renewably sourced ingredients by weight, and second, the product must perform as well or better than petroleum-derived products.
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.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
