Well as soon as we are awarded one of the programs we're talking about -- look Bill, if I take about -- if I talk about, for example, our ship hulls scanning comprehensive solution, that's a multi-year program that we started four years ago. Four years ago from the feasibility, to the prototype concept, to finally developing the platform for ship hull scanning, we've delivered that. Now, that's a sizable opportunity for the business and that runs over a number of years. So, look, evaluation under these programs can take up to four or five years, and some of the programs we're on are more mature than others. But I think we're making good progress. For example, this year, although we still haven't received an order, this year, for example, a Japanese program that we've been working on for four years now, that Japanese program was launched and the Echoscope PIPE C500 is a part of that program. So that now I understand that that vehicle is now being assessed and at sea with the end customer. So that's how it all evolves. But I know it takes time, but it's an area that we cannot afford and not to invest in heavily, because this is the opportunity for multiple recurring sales for our business. So, I think we're doing the right things on doing the front end work to go out and get on these programs to ensure at least that we're contenders. That's the first thing. Know about the program, become contenders, support the programs, and we're doing a lot of that, but that takes time, Bill. It is a -- and that's really where we will see the reward to grow. The commercial market, the profile of sale there, Bill, it's one sale in a project. I just talked about an island being built. If we get that order for five systems, then that's exceptional in the commercial market because when there's a project in terms of buying systems, the maximum system will be two systems and that can be a sizable, that would be around $700,000. But still, the point is that the opportunity to get multiples of sales and recurring sales comes from these programs, ship hull scanning programs, swimmer detection vehicles, mine countermeasure, critical asset management, these are all the programs that we are on. And also don't forget, Bill, over the years, over 30 ports in the U.S. carry our underwater inspection system, including New York, including California, New Orleans. All of these, at one time or another, invested in our underwater inspection system for -- if the President is coming in, it's the Echoscope that's used to sweep the port. So, I think we're making good progress in the areas where for our growth strategy -- it takes time, but I feel some of the programs are maturing.
