Shock absorbers transmit some of the shock directly to the isolated part. Engineers can mitigate the problem by adding dampers or with complex control systems, but the self-damped air spring offers a simpler option.
The self-damped air spring eliminates the need for shock absorbers in suspensions and vibration isolation systems.
Using a conventional air spring and a fixed-volume air chamber separated by an orifice, the design creates a force that is 180 degrees out of phase with the force-in function.
Isolation improves because the initial force from the input is absorbed totally by the spring with no damping. Damping occurs naturally and only when needed. Damping forces up to 30% of critical have been measured.

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
