Title: David Harry Smithgall: Innovator in Optical Technologies and RFID Solutions
Introduction
David Harry Smithgall is a notable inventor based in East Windsor, NJ (US). He has made significant contributions to the fields of optical technologies and radio frequency identification (RFID) solutions. With a total of 5 patents to his name, Smithgall's work has had a meaningful impact on various industries.
Latest Patents
Among his latest patents is the "Fiber defect detection apparatus and method." This invention provides methods and apparatus for detecting defects, such as air lines, in optical waveguide fibers. The technology employs scattered light interference signals produced by a fiber clad measurement system that transversely illuminates a fiber with a laser beam. Defects in the fiber generate characteristic peaks in the frequency spectrum of the scattered light signal. By filtering the scattered light signal to eliminate components associated with the fiber clad measurement system and the fundamental component associated with the fiber, the defect-related components in the scattered light signal can be determined. This leads to the generation of a defect detection output pulse for each detected event. Additionally, Smithgall has developed a "Luggage tag assembly," which is a low-cost RFID tag designed for identifying objects such as passenger luggage. This tag is programmed with essential information, including the origin, destination, and name of the passenger. The integrated circuit within the tag is powered by incident radio frequency energy, allowing for efficient communication and identification.
