I enjoyed this article - I really like these types of fasteners and would love to see them in more designs. My laptop was acting cranky the other day and when I examined the bottom I could see lots of dust lodging in the fan grill. I decided to take the bottom panel off to blow it out and it was such a delight when I discovered it had captive panel screws. I kept telling hubby how cool they were as I unscrewed each one and didn't have to worry about chasing small bits of hardware!
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
