Rich, I sympathize with you as far as the kids go. It is tough.
As far as safety, it is imperative in many of the systems we interact with in these times. If safety is not built in, people will not trust them. Fortunately we have standards like IEC 61508. In aerospace, you have similar standard, like DO-254. The safety record of those systems is very good.
What the write-up does not include is just what sort of products the standard applies to. For our products it would seem that writing the control code so that any deviation from the correct sequence of actions stops everything may already be in compliance. That type of programming did not make any distinction between deviations that were unsafe and those that had no safety impact at all. Any deviation was a show-stopper.
But then I have also seen other safety rules, mostly hardware, that seem to be aimed at drunks bent on self-destruction. Perhaps those standards should be revisited now.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
