Title: David H Xu: Innovator in Lens Inspection Technology

Introduction: David H Xu is a pioneering inventor based in Shanghai, China, known for his contributions to the field of lens inspection technology. With a keen focus on enhancing the quality control processes in the manufacturing of contact lenses, he has developed a notable patent that aims to streamline and improve inspection methodologies in this sector.

Latest Patents: David H Xu holds a patent for an **Automatic Lens Inspection System**. This innovative system is designed to inspect contact lenses suspended in saline solution within a lens holder. The process begins with capturing a first electronic image of each lens in its holder. Following this, a second image is taken after the holder rotates, allowing the solution and lens to move. By comparing the two images, any dark spots from the first image that move relative to the second image are identified as artifacts due to contaminants or markings. His invention automatically inspects critical features such as the lens rim, optical zone, printed logo, and colored iris area for defects. If any defects are detected in these areas, the lens is rejected, thus ensuring quality assurance in the manufacturing process.

Career Highlights: David currently works with Wesley-Jessen Corporation, a respected player in the optical industry. His involvement in the development of the automatic inspection system has significantly contributed to advancing the production standards of contact lenses, helping to ensure that consumers receive safe and defect-free products.
