Thank you, Andrew. Let's briefly discuss where we are as a company right now. Our current customers and many potential new customers have told us that technically our railcar inspection portal is the best-in-class in terms of performance, reliability and standardization of the hardware software, IT infrastructure, and artificial intelligence. Major advancements have been made in AI development. And I'm pleased to say that all of Duos’ customers are using our AI detections catalog of 40 plus use cases with excellent results. In some applications, our customers are using the portals and detections catalog to obtain regulatory waivers. We have continued to invest in research and development to stay at the forefront of the industry. This coming year we will deploy a new thermal undercarriage examiner, a new 360 degree wheel and brake inspection system and a new hot bearing detector system, all of which can be integrated into the existing railcar inspection portal. Another key technical breakthrough deployed to the track edge is a system update whereby the portals can acquire, compute and present inspection results in as little as 60 seconds after the railcar passes through the portal, which allows for instant notification to train crews, dispatchers and railroad mechanical teams. This achievement has been publicly recognized by two of our technical partners, Dell Computers and Nvidia. Another compelling feature is that our machine vision AI safety data is exchangeable and can be uniformly distributed amongst the stakeholders of the larger rail network in near real time. Commercially, we have a lot of high level interest, we have a high level of interest for all the Class 1s, several short lines and passenger railroads. Our backlog is at the end of the quarter of approximately $6.4 million, within a $5 million to $7 million of near term contract modifications, as well as multiyear service extensions expected on next two quarters with existing customers further emphasizes the long-term value in the RIP program. We currently have active proposals and evaluation with a handful of different rail carriers, or dozens of new portals, which also includes larger international opportunities. As we've always stated, the closing cycle for new CapEx deals is slow and episodic. That is exactly why we've decided to shift our focus to the subscription model, which does a couple of things. First, it doesn't change our original total addressable market of 150 portals to effectively cover the North American network. Second, it now as hundreds of car owners, lessors and shippers, many of whom have shown strong interest in using our safety data to more effectively manage the maintenance of their fleet to improve safety and overall car utilization rates. We currently have two subscription customers, one is a passenger rail carrier, and the other is one of the largest car operating companies in North America. We are also in discussions with a dozen other prospective subscribers. I expect that with support from our partners, our subscriptions will grow significantly in the near future to promote a safer rail network. So now let me outline our plan and the key milestones to watch that will ultimately set our course for a profitable business. The first key milestone is partnering with existing customers where we already have portals, which will enable us to offer subscriptions to car owners and shippers. We were also in discussions to build a first subscription portal where we will own and operate it at one of the nation's busiest interchange points for hard hazardous cargo. As you can imagine, post these Palestine, there has been renewed interest across the industry to share safety data from wayside detection systems. In this concept, a real carrier benefits by having cars arrive on its network and better mechanical condition, which is both safer and an enabler to improve overall car utilization rate. The carriers can also benefit by seeing the railcars before they accept them and interchange with them. The second is continuing our commercial efforts with the other Class 1s not using our technology. I recently read a government report on lessons learned from the implementation of positive train control. The primary challenge was to achieve interoperability and the ability to easily exchange data amongst carriers and other stakeholders. As with the adoption of any safety technology, the long game is to have this interoperability and do it with minimal investment across all stakeholders. The third is to continue to work with our railroad partners to gain support from key industry stakeholders, such as the American Association of Railroads, the Federal Rail Administration, labor unions, and others. The fourth is to work with our partners on a southern border strategy. One of our Class 1 partners is already using our technology which is highly capable of identifying illegal riders for waiver application to move – to rail farmers faster and more securely across the southern border, as nearshoring becomes a more critical issue for the United States. We are currently in discussions with our rail partners, and federal rail, federal and state law enforcement agencies to expand the use of our technology to better enable these organizations to securely move commerce across the border. The final milestone is to expand our solution international. We already have several proposals and active evaluation for a handful of portals and have several additional opportunities that we're working on in our commercial pipeline. To be clear, our plan is that the Duos railcar inspection portal becomes the industry standard for machine vision and wayside detection enabled with AI. The portals will be installed across the entire North American rail network and eventually around the globe, whether owned by Duos or our customers and operate them for the sharing of safety data amongst the Class 1s, short lines, passenger, regulatory other federal state and local authorities. Portals would form part of an overall safety management system where data from all wayside detection systems, onboard telemetry data and other real track network data can be viewed in a single system. Highly functional analytics and AI will be applied and information used by human operators to make decisions and take actions in near real time. If we were successful in achieving our goal, we would have 100 to 150 portals installed on a North American network, all allowing for data access via subscriptions. Under this model, the business would generate annual recurring revenues that are many factors above our current CapEx focused business model. So what are the risks to achieving our goals? Primary risk are project delays and timing of revenue recognition and cash collection. The current CapEx model remains episodic and difficult to forecast, but will continue to be a part of our revenue structure in a foreseeable future. We have shown we can manage through this in the past, and we will continue to see this kind of pressure as we transition to a subscription model. Another risk is the speed with which the industry will adopt this cutting edge technology. As I've said, there is broad consensus across all railroad stakeholders. The technologies such as ours needed and will be widely implemented. The impending Railway Safety Act, whether it passes or not, has spurred the entire industry to get even more focused on safety. Our technology can also be a key technical enabler for our rail operators, and law enforcement agencies at southern border. In closing, I want to highlight that I believe our company has a leadership position in a rail sector, with machine vision and AI wayside detection, our transition over the next 12 to 18 months into a recurring revenue business model, selling into a growing demand for this technology puts us in a very strong position to give an unexpected high return on investment to our loyal shareholders. I also believe that despite our current short-term revenue challenges, the company remains in good financial position with sufficient cash from operations and near term business opportunities that will accomplish the key milestones I discussed earlier, and provide a good return to our shareholders. And with that, we're ready to open the call for your questions. Operator, would you please provide the appropriate instructions?
