Latest Patents

One of his latest patents is titled "Method and apparatus for detecting corrosion under non-ferromagnetic." This innovative method utilizes nuclear magnetic resonance techniques to detect corrosion within metallic structures, such as aluminum, that are covered by non-ferromagnetic coatings. The process involves placing the metallic structure within an external static magnetic field and applying a series of radio frequency preparation and inspection pulses. The resulting nuclear magnetic resonance response signals are analyzed to determine the presence of corrosion.

Another notable patent is "Detection of thermal damage in composite materials using low field." This technique focuses on identifying thermal damage in resin-matrix composite materials through low field NMR nondestructive testing. By measuring the spin-lattice relaxation (T.sub.1) at low magnetic field strength, the method can detect thermal damage, which is indicated by an increase in T.sub.1 and T.sub.1D.
