Watching that demo, I have to wonder how it figures out the hidden shaft on both ends of the thumbwheel, and thereby that the wheel is moving part. Then there's the tang on the moving jaw that slides in the slot and has the "teeth" that are moved by the thumbwheel. Are they scanning with MRI? ...with that little hand-held gun?
I work in the plastic industry. We just had a presentation that showed this exact same thing. I wonder if I gave them a picture of a Playmate what they could.

There's no place for a beam to see the upper shaft. None. Same for a few other features.
I'm guessing that they left out some steps to keep the video moving. There is probably an intervention by a CAD engineer which tweaks the scan and adds details like the thumbwheel.
On the other hand, I don't understand the physics inside a silicon processor chip, either... I used to know the basic physics inside computers, but no more. These guys might be doing something like MRI, although I don't know how well that works on metal objects.
