Wow. Thank you, Dr. Bob. Thank you and Good evening, everyone. Before we discuss our financial results, I want to take a minute and thank Dr. Bob for his immense contributions to Cognex, and for instilling the enthusiastic entrepreneurial spirit that is the hallmark of our company. Dr. Bob, and the unique culture he built over the past four decades, will forever be a part of Cognex. Now for our financial results; 2020 was a roller coaster ride, both for the world and certainly for us at Cognex. We entered 2020 optimistic about growth. 2019 has been a challenging year in which lower spending by customers in our two largest markets, automotive and consumer electronics resulted in our first revenue decline in nine years. However, after the global COVID-19 outbreak in March 2020, and the related supply disruptions, business shutdowns and capital investment pullback, we recognize that the outlook for 2020 had changed. We no longer believed 2020 would bring the broad-based strength we had expected when we started the year. Given the circumstances, we quickly took steps to adjust our operating expenses to align with more modest growth. These steps included a workforce reduction, which was difficult for us, and an organizational realignment that better focused our internal investments on high growth opportunities, and important operational priorities. As a result of these changes, we've been better able to support Cognoids and customers through our own difficult pandemic related challenges. From a business perspective, the second half of 2020 was much more positive than initially expected. You can think of it as a tale of two hogs. Revenue in the second half of the year was up a surprising 41% over the first half. As a result, we reported good financial results for 2020, setting a 40-year record for annual revenue. Revenue grew by 12% year-on-year, thanks largely to highest spending by customers in Consumer Electronics and Logistics, where we benefited from strong partnerships with market and technology leaders that fed well during the pandemic. Spending in the broader factory automation market has also improved from depressed levels in Q2. In Consumer Electronics, revenue increased by approximately 30% year-on-year. It also represented roughly 30% of total revenue and became our largest market. Much of our revenue in Consumer Electronics relates to the assembly of smartphones and the production of related components. In 2020, there was also a larger relative contribution from other electronic devices necessary for online learning and the work-from-home dynamic. Logistics revenue grew by approximately 40% over 2019 due to growth in the e-commerce sector. Now representing approximately 20% of total revenue, Logistics surpassed Automotive to become a second largest market. We benefited from major e-commerce and omnichannel retailers investing in automation to enable higher throughput and cost productions. Other sectors of Logistics such as bricks and mortar retail and airport baggage handling struggled in 2020. Further bright spots included medical-related industries and semi, both of which grew double-digits year-on-year. We're proud that manufacturers serving the healthcare industry are relying on Cognex to help make COVID vaccines available to the public. More specifically Cognex machine vision and deep learning are an integral component of production machines worldwide to ensure the highest quality standards and full traceability in COVID vaccines. Applications include inspecting vials for defects; ensuring vials of vaccines are filled to the correct level and a free of contaminants and ensuring that vaccine kits are packaged correctly. That's most of the good news. On the negative side, automotive revenue declined by approximately 20% year-on-year, as business shutdowns further worsened already weak fundamentals. As a result, the automotive market which was our largest market in 2019, dropped to third place in 2020. Automotive is improving somewhat from its most depressed levels in Q2, and increased Q4 year-on-year for the first time in several quarters. However, it remains at a significantly lower level than in recent years. Let's talk now about Cognoids, our people. Our achievements in 2020 were the result of the dedication of Cognoids around the world. They exemplified our strong culture by working hard and moving fast in a volatile environment to meet significantly increased demands from a few of our existing customers to win new customers tend to successfully manage our supply chain. Because of our efforts, we launched powerful new products that have made us Superior Vision tools easier to use, and therefore available to a wider audience. The most important introduction in 2020 on one of our most successful product launches ever was the In-Sight D900 smart camera. Leveraging In-Sight's widely recognized easy builder interface, the D900 enables both existing Cognex customers and new users of machine vision to apply our deep learning tools to inspect surfaces for defects. Popular applications include the detection of scratches, and chip surfaces that were previously too difficult to solve using traditional rule-based vision. We also integrated deep learning technology that we acquired with SUALAB. These techniques are now sold together with our ViDi tools running on the Cognex Vision Pro Deep Learning software platform and are being widely adopted by more sophisticated customers to solve their most complex vision problems. Revenue from applications utilizing our deep learning technology more than doubled year-on-year in 2020. As we look at the opportunities ahead, we believe we are just scratching the surface no pun intended, of what we can accomplish. We believe deep learning and Logistics will be major contributors to growth in the years ahead. Now let's talk about 3D. Last month, we launched the In-Sight 3D-L4000, an exciting new smart camera platform for the fast growing industrial 3D vision market. The 3D-L4000 leverages our successful In-Sight-intuitive spreadsheet interface, making it easy for our broad insight customer base to use powerful new vision tools created for true 3D inspection. Under development for some time, the 3D-L4000 packs novel capabilities into a compact form factor without the need for a separate PC. Exciting features include patented optics technology for superior image quality, and the broadest range of 3D vision tools available in a vision system. We believe the 3D-L4000 is a breakthrough product that makes 3D as easy to use as 2D vision. It positions us very effectively against competitors who have significant sales and profits in this area. Both Cognoids and customers are excited about these new products and others we have in our pipeline. Now I will turn the call over to Paul for details of the fourth quarter.
