Thank you, Dr. Bob. Good evening, everyone. I'll begin my remarks with an overview of the last year. I'm pleased to Cognex's outstanding performance in 2014. Our team's ongoing efforts in new product development and sales force expansion delivered great revenue growth and higher levels of profitability. Growth in 2014 came from the factory automation market, where new annual revenue records were set in Europe, the Americas and Asia, excluding Japan. Revenue from surface inspection also set a new record. ID products continued to grow well above our 30% long-term target. In addition, we saw very strong performance from our Vision products, which also grew in access of 30%. From an industry perspective, consumer electronics, automotive and logistics were important contributors to growth in 2014. Gross margin remained strong at 75%, despite volume pricing and higher support costs for our largest customer. Operating margin expanded to 30% and net margin to 25%. Both represent significant increases over 2013, reflecting the substantial leverage that incremental revenue has on our business model. We delivered earnings of $1.36 per share, setting a new annual record that is 65% higher than the prior record of $0.83 per share set in 2013. Now, for details of the fourth quarter. We ended 2014 on a strong note. Revenue for Q4 was $117 million, which exceeded the high end of our guidance. This was the result of better-than-expected demand from the factory automation market. Revenue from factory automation in Q4 was $93 million, representing our second highest factory automation revenue quarter of all time. Growth for factory automation, as reported, was 16% year-on-year and 20% in constant currency. Looking at factory automation from a geographic perspective, we were pleased to see double-digit revenue growth over Q4 2013 in 3 of our 4 geographic regions. Asia, excluding Japan, was our best performing region in terms of percentage growth, increasing more than 30% year-on-year. An important contributor was Greater China, where we continue to expand and diversify our business into many industries, different applications and new customers. In Europe, factory automation revenue grew in excess of 20% over Q4 2013, even though it was negatively impacted by a weaker euro. Strong performance across several industries, including automotive, consumer electronics, medical devices and food, drove factory automation growth in this region. Factory automation revenue in the Americas set a new quarterly record in Q4. Revenue grew in the low teens over Q4 2013, which had been particularly strong because of the substantial revenue from our package delivery company. In Japan, the factory automation market continued to struggle and unfavorable currency exchange rate further hurts results. Our revenue from this region, as reported, declined to 27% year-on-year or 17% in constant currency. Moving on. Revenue from the surface inspection market was also above our expectation. Surface inspection revenue was a record $18.7 million in the fourth quarter, which is a substantial increase both year-on-year and sequentially. We continue to perform well in surface inspection, and demand remains at a high level. In the semiconductor and electronics capital equipment market, revenue was $5 million in Q4. Semi revenue softened considerably at the end of 2014 following several quarters of growth. That fact, combined with news from the field, leads us to believe that we passed the high point in semi sales to this cycle. Turning next to operating activities. Based upon the confidence we have in our strategies and the opportunities we see, we continued to make significant investments in our business during 2014 to drive growth in the years to come. We invested heavily in engineering, spending $60 million on RD&E in 2014, an increase of $12 million or 25% over 2013. That investment helped launch more new products in 2014 than in any year in our company's history and we have additional major products slated for introduction in 2015. We expanded our sales channel and significantly broadened our market reach. Activities included adding a significant number of people to our sales and marketing organization, increasing sales force productivity through systems upgrades and process improvements, and investing in our surface infrastructure to support large customers and logistics and other high-growth markets. We added new offices and expanded facilities around the world, including our operations facility in Cork, Ireland to ensure adequate capacity for higher levels of the business. We feel good about our ongoing investments and we believe that they are important to address the growth potential we see for our company. In summary, we reported outstanding financial results to 2014. The result of the team's strong execution on our long-term strategies. With the excellent progress we made during 2014, we believe that 2015 will be another record year for Cognex on both the top and bottom lines. Here is the specific guidance for Q1 of 2015. We expect revenue of between $108 million and $111 million. This range represents growth of 19% to 22% year-on-year, even with an expected unfavorable impact from a stronger U.S. dollar. Gross margin is expected to be in the mid-70% range. Operating expenses are expected to increase by up to 6% from Q4. We're gearing the organization for a higher level of revenue expected in subsequent quarters. In addition, we see an increase in stock option expense and incremental fees related to our patent lawsuits against Microscan. The effective tax rate is expected to be 19%, excluding discrete tax items. Now let's open the call up for your questions. Operator, we are ready to take questions.
