Thanks very much. It’s a very good question and we are taking a deeper approach on some of these, that's a little bit different. So, even look at the handheld welding, we've taken a different go-to-market approach there. We've partnered with our LightWELD with premier welding supplier in North America, Miller Electric that supplies today or had supplied to-date with a conventional MIG-and-TIG experts in the welding they provide these systems and they're working with us in partnership to take that on to label. It is a Miller product. So, they're seeing that this is the right way to go in welding. And they're seeing that because you're able with our system, our LightWELD system, we build the process. So, again, this is talking about that process development. We've actually built it into the system. So, you can actually dial in, hey, I'm doing aluminum on aluminum or aluminum on copper and the system will set itself and you can go and do that welding, where in standard processes, if you're a MIG or TIG weld or you might have to apprentice for years before you can do those processes. Here, you can do that -- I've even welded with the system. So, you can go from years to hours being confidence. So, that allows us a different market -- go-to-market strategy, again with Miller and putting that into the market. And then again, pushing on that that application and that process development, again, taking and optimizing not only the lasers for a particular process, let's take something like cleaning we can -- that's, again, replacing a process that would potentially have been done with chemicals, right? So, something better for the environment now using a laser, but you have to optimize the laser to be able to do that. So we're making high-power lasers with short pulses that are optimized for that. But then you also have to drive -- the scanning has to work as well. So, we've actually developed case use scanners that are very high speed for that cleaning applications as tied to that laser, the tie to the process. And then working with the customer, be able to provide the solution, right, either in a subsystem or a system level. So, again, a different go-to-market strategy because we need to solve the problem in that non-laser space. right, and be able to provide that whole piece. So, that's an investment that we've been making, as I mentioned, and that's a change in go-to-market that we're going to continue to invest in.
