Ugh! Seems like a classic case of shortsighted design thinking and cutting corners. We had a number of ceiling fans in our former house and we pretty much universally had problems with all at some point in time with the various settings being off kilter. That said, the fans were not the same model and not even from the same manufacturer. With one, the settings for low, medium, and high speed were actually backwards. It wasn't anything that was dangerous or that we even took time (and expense) to fix. The bother was we had to create kludgy workarounds just to keep them going.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
