Title: Innovations by John David Stevenson
Introduction
John David Stevenson is an accomplished inventor based in Livermore, CA. He holds a total of 3 patents that showcase his expertise in advanced inspection technologies. His work primarily focuses on methods for detecting and analyzing materials, particularly in the context of nuclear security.
Latest Patents
One of his latest patents is titled "Integrated primary and special nuclear material alarm resolution." This patent discloses methods for inspecting an object through a two-step scanning process. In the primary scan, a truck or cargo container is completely scanned using a fan beam radiation. The transmitted radiation is measured with an array of detectors, and the information is analyzed to determine the presence of high-density, high-Z, and fissionable materials. If the container alarms in specific areas, a secondary scan is performed to confirm the presence of special nuclear material.
Another significant patent is "High-energy X-ray-spectroscopy-based inspection system and methods to determine the atomic number of materials." This application describes systems and methods for X-ray scanning to identify the material composition of an object. The system includes an X-ray source that projects a beam onto the object, with detectors measuring the energy spectra of the transmitted X-rays. This data is used to determine the atomic number of the object, aiding in material identification.
