Title: David W Prine: Innovator in Structural Monitoring and Welding Flaw Detection
Introduction
David W Prine is a notable inventor based in Maywood, IL (US). He has made significant contributions to the fields of structural monitoring and welding flaw detection. With a total of 2 patents, his work has advanced the understanding and technology used in monitoring material integrity.
Latest Patents
One of his latest patents is a "Method and apparatus for structural monitoring with acoustic emission." This innovative system is designed to monitor fatigue crack growth in metals and other materials, such as those found in highway bridges during normal traffic loading. The system utilizes transducers placed on the plates being tested to detect acoustic emissions from specific sites. By applying recognition methods to the acoustic emissions, flaws can be identified against a background of random noise. The pattern recognition technique involves several tests to locate the position of flaws effectively.
Another significant patent is the "Acoustic emission system for welding flaw detection." This system is utilized during continuous welding processes and employs a transducer to generate a signal burst for each acoustic burst from the welded article. The system amplifies and filters these signals to focus on specific frequency ranges. A ring-down counter counts the filtered signals, and if the count exceeds a predetermined threshold, it triggers an alarm device to indicate the presence of a weld flaw.
