Title: Innovations by John C Lichauer
Introduction
John C Lichauer is an accomplished inventor based in Irwin, PA (US). He holds 2 patents that showcase his expertise in advanced inspection technologies. His work primarily focuses on enhancing safety and efficiency in nuclear energy applications.
Latest Patents
One of Lichauer's latest patents is titled "Position-based sampling for eddy current inspection of steam generator tubes." This innovative method utilizes an eddy current sensor to inspect steam generator tubes while minimizing the risk of damage to the sensor. By controlling the acceleration and deceleration of the sensor, Lichauer's approach reduces probe stresses, thereby decreasing radiological waste and radiation exposure for workers. The system records eddy current signals at evenly spaced locations along the tube, allowing for variable sensor velocity without compromising data integrity.
Another significant patent is "Non-contact flaw detection for cylindrical nuclear fuel pellets." This system continuously transports nuclear fuel pellets along an illuminated path while rotating them. A line scan camera captures a series of images, which are then digitized for analysis. The processor evaluates pixel values against adaptive thresholds to create a binary map of 'good' and 'bad' pixels, enabling the identification of surface flaws. This innovative approach enhances the safety and reliability of nuclear fuel pellet production.
