word choice - Alternative expressions to explain jargon in a sentence?

Those are both pretty good: unfortunately, there aren't a lot of good ways to define industry specific terms in the text, so if you have to use the term, you're going to have to define it.

I like the second one better. Put a period, then define belt (You might say, "Belt is an industry term meaning blah blah blah").

One thing I will say, "being usually presented" should be taken out and shot. Is there a reason you can't just say "are presented" or "are usually presented"?
