@cnorton, sorry, didn't have the focus on this window.
Alex explained that "qualified attendees" are anyone logged in here, basically -- if you're interested enough to attend, you "qualify". So I'm suspecting that they're going to take the list of people who registered AND logged in, and do some form of essentially-random drawing from that list. In a perfect world, they might "weight" any one person's "entry" on the basis of "participation", not just lurking, but that's just me (and a very normal human self-interest) speaking...
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.
