Thank you, Brent, for the financial overview. As always, I'd like to thank everyone for joining us on the call today and for your interest in ClearSign. Before I start, I'd like to welcome David Maley, a newest addition to the ClearSign Board of Directors. David joined us just days after our last call one month ago. David is a seasoned investment executive with broad experience, specializing in microcap business, finance and compliance. I welcome David to the Board at this exciting time for the company and look forward to working with him in collaboration with the other directors. On the call today, I will review our business segments starting with our process burners and then move on to boiler burners. I have some comments relating to our sensing partnership with Narion Corporation. I will then discuss the outlook for the rest of the year. I'll also note that our last call was not that long ago back on April 24. And I do suggest that anyone not familiar with our last 2023 year end call also refer back to what was presented then. I'll now turn to the developments in our process burner line. Yesterday, we announced the final source test results for the second heater from the two heater order at Kern Energy, who until now we have not been able to name. As I've stated previously, these are our two most significant processes of retrofits to date. They are the two largest and also have fuel gas that varies significantly and with a hydrogen content ranging from 0% to 80% of the fuel's volume. These heaters are side by side, one fitted with eight burners, which is completed first and included in our press release on January 17, announcing the successful third-party performance test. And the second heater, which is fitted with five burners, was retrofitted in late March and was tested in April. On the last call, we noted that we were waiting for the official report from that source test. That has now been received and the successful performance of our burners confirmed. A few days after our last call, on April 30, we received and announced two additional purchase orders from the same customer. These orders were for the detailed engineering of burners to be installed in two more heaters in the Kern Energy Refinery. As we have discussed before, it is quite common for projects to be released in phases with initial engineering being the first. These two heaters are smaller than the previous two, one with a single burner and the other with three. But nonetheless, they will provide revenue and valuable references for ClearSign, especially in the refining industry. It is encouraging to receive repeat orders for our technology. Kern Energy has been an early customer of ClearSign and has ongoing experience with the operation and performance of ClearSign's burner technology. Kern Energy prioritizes their clean air and clean fuel initiatives and actively seek technologies that go beyond established emissions limits and to further reduce their environmental footprint. We believe that the increasing inclusion of ClearSign's technology into their refinery is evidence of and a significant step towards these objectives. Beyond this, we have the 20 burner order for Los Angeles Refiner in production. As we previously stated, the final witness testing of these burners went as planned. These burners are now being fabricated by our partners, Zeeco, and are scheduled to be shipped to our client in Los Angeles area of California late in third quarter this year. When up and running, these will be another two heaters, this time with 8 and 12 burners, which will provide an additional and very significant reference for us, especially given their location in the large refining hub in the Los Angeles area. Shipping these burners will enable us to recognize revenue from the production phase of this project. This past month has included significant activity from a sales perspective. On the last call I mentioned, we have end user refiners request that the engineering companies working for them contact ClearSign to include us in the evaluation of solutions for their projects and the support of those inquiries has continued through this past month and is ongoing. New inquiries include some interest from Europe also which is encouraging and a development we are pleased to support. On our previous call, I mentioned the development of a product line developed for an enhancement of our current boiler burner technology that has enabled an efficient and effective ultra-low NOx solution for a particular type of horizontally fired process heater, which is widely used in the midstream that is the fuel processing storage and transfer industry. This new product line has been the subject of multiple different customer engagements in the past few weeks. As with the refining process burners, many of these opportunities have been brought to us by third party engineering companies seeking the best solutions for their clients. This is a distinct difference and a significant development from only a short time ago, when most of the opportunities will limit to those resulting directly from our own outreach. We are still doing that, but the addition of inquiries from clients where they need reaching out to us is significant. On the last call, we noted that we're about to install the first commercial version of our Department of Energy funded hydrogen burner development project into a test furnace on the site of our partner Zeeco. Since that update, we have run that burner and I'm happy to report that the results exceeded our expectations, especially for the first version of new burner. Some of you may have seen our post on LinkedIn showing a photograph of the flame and some of the initial results with NOx numbers at four parts per million with 100% hydrogen fuel. Due to the results we have already achieved, we anticipate that we will be able to accelerate the commercial availability of this new burner design. This new technology has gained significant interest amongst our customer base with whom we have been able to discuss the program. A particular interest to clients we have talked to is a prospect of being able to upgrade our current burner technology to a future 100% hydrogen capable burner, while maintaining the same emissions profile. Turning to boiler burners, we or our partner Rogue have a steady cadence of customer inquiries to quote and pursue and accordingly a growing sales funnel. Key opportunities since our last call cover a wide range of industries from high-tech production facilities to education facilities to food and beverage producers and industrial production. We also have in production the first in a series of four burners for induced processing company in Central California. We also have a large 1,200 horsepower boiler banner for recycling company in Central California. This boiler is on that customer site and is scheduled to start up in the next few weeks. This is especially meaningful because it will be our first burner in the largest size range requiring a 2.5parts per million NOx guarantee. We anticipate that this will provide a very meaningful reference in the industry and a powerful demonstration of the capabilities of our ClearSign Core technology. A few words regarding our China operations, we have a lot of topics to cover in the full year-end and fourth quarter call last month. Now that the need to prioritize, we did not give an update on operations in China because there's not a lot to report. A project there has had some delays, particularly an urgent need on the part of Shuangliang to provide a boiler to one of their customers that resulted in our test boiler being needed and shipped to that customer. A new boiler for us to use in a burner certification process is in production and we look forward to being able to reinstall our burner and resume our preparation for certification. We expect our general sales and promotional activities to continue in parallel with our burner certification process. At this phase of ClearSign's commercial development, now that we have proven technology, our reference installations operating in customer sites. Our priority is developing sales. A big part of this is getting engaged with customers who have projects either now or in the future that will benefit from the capabilities of ClearSign's technology. As you would expect, we have many initiatives ongoing to this end. Of particular note, since our last call, we have engaged our first third-party sales consultant. This consultant is based in the Houston area, but brings valuable connections nationwide in addition to the industrialized Gulf Coast area of Texas and Louisiana. He also has connections with many environmental consulting companies working in our field and local and federal environmental regulators. In this industry, a typical sales agent or manufacturers representative, we'll have a small portfolio of clients who provide products or services in a similar industry or to a customer group, and they will specialize in our target market. This enables them to develop extensive contacts and relationships, and as a result of the multiple products or services that they represent to keep them in frequent contact with their customer base. In our case, in addition to this, our sales consultant is engaged with many consulting firms, who get involved when end users are planning and permitting environmental projects or have new requirements to accomplish. He's also engaged with local regulators, which we anticipate will help provide information related to future client needs and regulatory drivers. In a similar market-related topic, we have been watching the development of air regulations in Texas, which are driven by the increase in severity of nonattainment within the national ambient air quality standards for Ozone in the Greater Houston, Dallas and San Antonio regions. While the changes to these regions nonattainment status were identified before the COVID years, not much progress was made until recently when the Governor of the State of Texas accepted these findings at the end of 2023. As a result, the state regulators are now working with the federal EPA to develop a mutually acceptable plan to improve air quality in these regions. While these developments are still at the high level planning stage between the state of Texas and the Federal EPA, detailed revisions to air quality regulations are expected to follow. These will provide the mechanism to achieve the to-be-agreed air quality improvement plan. We believe this is an important development for two reasons: First, we believe that future and new clean air regulations in Texas will create demand for our products, especially because of the Gulf Coast region of Texas has the highest concentration of refining and petrochemical industry in the United States; and secondly, our experience suggests that just the anticipation of NOx reduction requirements for the region will initiate studies and planning by and on behalf of the industries in the effective areas. We, of course, expect that the resulting evaluation of possible solutions by our customers will result in increased opportunities for ClearSign. It is also worthy of note that just the anticipation of NOx reduction requirements in the future. In addition to the initiative of decarbonization is creating an increased interest in ClearSign Technologies. One indication of this was the measured attention and engagement attracted by our simple LinkedIn Post showing ClearSign's new 100% hydrogen bonus, which is significantly higher than the attention and engagement with respect to any other subjects posted by ClearSign this year. I want to also give a quick update on some developments by our partner, Narion Corporation. While we do talk mostly about our burner technology, ClearSign does have unique sensor technology and we have partnered Narion to develop that technology into commercial applications in markets outside ClearSign's expertise. Eddie Kwon, the owner and CEO of Narion recently gave a presentation at the KAUST at the King Abdullah University of Science and Technology in Saudi Arabia, the Aerospace Propulsion and Energy Systems conference. His presentation was about the implementation of sensors to increase efficiency and safety of aircraft. One exciting capability of our sensing technology that Narion is developing is the ability to measure the flammability or propensity to ignite or burn off a gas mixture. A second is the ability to measure the presence of a flame and at very high speeds, enabling the detection of a flame front and the rate of which it travels. The former has extensive applications in the transport sector. Particularly aircraft, both commercial and military. The second has received great interest from entities involved in rotating detonation engines, a technology with significant military applications. If you're not ready in doing so, I encourage you to pay attention to Narion. They have some very exciting technology development projects and collaboration opportunities. In closing, it has just been four weeks since our last call, and I encourage anyone who is not aware of what we said then to refer back to that call also as the information here is especially relevant given the short time period between these two calls. We believe that our business is in a good position. We've now had two consecutive quarters with revenues above $1 million, and we have more orders in both process and boiler product lines to start up and others that are shipping in the coming quarters. These initial installations are helping establish our technology in the industry. As an example, I was at the American petroleum industry spring refining and Equipment Standards meeting in St. Louis earlier this week. This is a conference where subject matter experts from across the industry gathered to review and update the API equipment design and operating guidelines. From my conversations with our conference, it was evident that our operating installations have a major influence on how ClearSign is perceived and the openness of our potential customers to consider ClearSign solutions. This is resulting in customers approaching us to discuss projects and possible new business opportunities. For balance, it was also apparent that while our progress is noticed and influential with those who are familiar with it, there's a portion of our industry that is not familiar with ClearSign. We're not aware of the progress we have made over the last five years, and this is something we will continue to address. As I stated on our last call, again, here today, our top priority at this time is growing our sales. We now have technology developed and first installations of operational and client sites in all our major product lines. These provide valuable references for prospective customers. This is critical as our customers do look for the experience of others operating our technology to validate what we offer. We do not yet have enough installations or run time of those installations to be considered fully mainstream in the industry, so every new installation and start-up is especially valuable for us. We do also have some other significant wins including the two best available control technology determinations that we received earlier this year based on the South Coast Air Quality Management District review of our process burner installations. Our goal is to leverage these determinations to increase awareness and acceptance of ClearSign in the market to ultimately increase the number of customers and projects that we get to engage in and generally build confidence, that we offer the most economical and efficient solution for our customers. Earlier, I mentioned the engagement of a third party sales consultant and is also part of this prioritization. Additionally, as a goal is the constant development of our technology and product lines, we continue to focus on the development of our technology. In the past four weeks, the progress in our hydrogen burner project and the interest that we have already received in the industry has been significant. Also, we have made significant progress in the ongoing development of our new horizontally fired process burner product line, building on what was discussed in more detail in our last call. Looking forward, noteworthy items on our horizon will be the anticipated start-up of our 1200 horsepower, 2.5 BPM NOx guaranteed boiler burner for the recycling company in California. Which will be a very significant reference for us, and our partner road combustion in California border. And also in the boiler burner product line, the shipping of the first boiler burner in a series of four a few fruit and vegetable multi juice processing company in California. We also have some significant technology projects underway, including our hydrogen burner project, which has shown great and early promise and was provisioned to our horizontal core strafe burner as used in horizontally five process heaters and potentially to enhance our boiler burner product line. We anticipate that both of these technology projects will result in products with enhanced performance and reduced production costs, and that will be less unique in the appearance as perceived by our customers. All of these we expect to enhance the growth of the ClearSign business. And with that, I'd like to open up the call for questions. Please, operator?
