Latest Patents

One of Taeho Ju's latest patents is titled "Detection and monitoring of cracks and fractures using nonlinear response to multimode acoustic signals." This invention discloses methods and apparatus for assessing microstructural defects in large structures. The technology utilizes third-order elastic constants to engender nonlinear excitation of acoustic modes, particularly at points of local stiffness changes or stress concentration, such as the ends of microcracks. A broadband multimode acoustic signal is transmitted through an interrogation region from a first transducer, while a second transducer receives an acoustic signal containing both linear and nonlinear components. By canceling linear terms and measuring the magnitude of the nonlinear acoustic response using time-resolved spectral analysis, a coefficient for acoustic nonlinearity is determined. This coefficient serves as a qualitative or quantitative representation of microcrack damage, allowing for the identification of damage location by region or time-of-flight. The portable or dedicated embodiments of this technology can be deployed on a wide range of structures of arbitrary shape.

Another significant patent is the "Integrated electrochemical nuclear decontamination system." This invention features an electrochemical cell that oxidizes a solution, providing a continuous and stable supply of an oxidizing ion solution for decontaminating metal and metal alloys. The electrochemical cell includes an anode compartment that oxidizes the solution in nitric acid or methane sulfonic acid at a rate equal to or greater than the rate of reduction. This system facilitates online measurement of the oxidizing ion solution and the dissolved radionuclides in real-time. The solution decontamination system effectively removes contaminants from the oxidizing ion solution, while real-time acoustic monitoring of the thickness of the contaminated surface enhances the overall efficiency of the process.
