Latest Patents

One of Liaw's latest patents is focused on "Machine learning to accelerate alloy design." This invention presents an innovative framework for the application of machine learning to identify alloys or composites with desired properties. For each output property of interest, the corresponding driving factors are identified, which may include material composition, heat treatment, process, microstructure, temperature, strain rate, environment, or testing mode. The framework assumes the selection of an optimization technique suitable for the application at hand, starting with simple linear or quadratic regression analysis. A physics-based model for predicting ultimate tensile strength is also presented, accounting for physical dependencies and factors in the underlying physics as a priori information. If an artificial neural network is deemed suitable, custom kernel functions consistent with the underlying physics are suggested to attain tighter coupling, better prediction, and extract the most from the usually limited input data available.

Another significant patent is the "Pressurized ferrofluid paint removal system using an electromagnet." This process involves removing paint by high-pressure waterjet blasting of painted surfaces, wherein the waterjet comprises a ferrofluid or other liquid containing tiny magnetic particles suspended therein. The particles may be in colloidal suspension or suspended by agitation and are preferably polymer-coated. This liquid-magnetic particle mixture lends itself to electromagnetic process control, run-off maintenance, and waste processing capabilities, allowing for effective process control and waste remediation options.
