ALEXANDRIA, Va., Nov. 11 -- United States Patent no. 12,466,451, issued on Nov. 11, was assigned to KB Signaling Inc..
"Method and system for estimating temperature-related forces in railway lines" was invented by Jeffrey Fries (Grain Valley, Mo.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method and system are for estimating forces in rails of a railway line which are due to the temperatures of the rails. Values of the electrical resistance of one rail of a railway track section are calculated. Based on the calculated values of the electrical resistance for the rail, corresponding values of the temperature of the rail can be estimated, and based on the estimated values of the temperature of the rail, e...
