ALEXANDRIA, Va., Jan. 20 -- United States Patent no. 12,529,735, issued on Jan. 20, was assigned to TOYOTA JIDOSHA K.K. (Toyota, Japan).
"Method of estimating magnetic field strength" was invented by Hayate Yamano (Susono, Japan).
According to the abstract* released by the U.S. Patent & Trademark Office: "Provided is a method of estimating a magnetic field strength with a higher accuracy. The method of estimating a magnetic field strength includes detecting fluorescence emitted from diamond having nitrogen-vacancy centers with an external magnetic field applied thereto, by irradiating the diamond with excitation light and sweeping microwaves; removing, as noise, a long-periodic component having a value greater than a preset threshold from...
