UL really trusts thermal fuses, they're reliable and can not be reset which calls attention to the user that something is very seriously wrong. If the oven was getting hot enough to trip the thermals, then something was seriously wrong and replacing the thermals would not be the cure.
I'm sure that replacing the firmware was the real cure, and that's scary. What if self-clean code was causing a runaway condition? There might be consumers that jumper out the blown thermal fuses rather than paying $260 for the proper repair and then they have a runaway oven with no way to shut it down.
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.
