Safety has a price and, though expensive, deliberately crashing cars remains a good way of testing an automobile's safety features. However, there is a new crash simulation facility that promises a decrease in the number of cars destroyed during tests. Developed by the German company Instron, and recently installed at BMW in Munich, the non-destructive method relies on reverse acceleration. To work, the car mounts on a rail-borne slide. A hydraulic catapult accelerates the car backwards, producing 70g shock levels. Controlled by the Siemens PC-based SIMATIC WinAC, which communicates with the system via the Profibus-DP and AS interfaces, the process uses reference traces of the motion parameters derived from actual destructive crash tests. The only difference is that they are "replayed" in reverse. Optical and electrical sensors, mounted on the slide, record performance of the car's safety equipment. Not only does the system save money and metal, it allows more frequent testing. Contact Juergen_Kraemer@instron.com or visit www.instron.com/ist.

As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
