Call them and let me know. Last I heard they were in a few trials. I know of no new product design projects but that doesn't mean it's the case.

However, we do know they have pared down their staff to a skeleton crew, minimizing their overhead to help maximize profits (60% profit margins approx), so I doubt there is a lot going on with R&D.

They also have patent pending status and last I recall they expected some news on that front, so who knows what new IP efforts could result. It's a wait and see right now.
