ALEXANDRIA, Va., March 12 -- United States Patent no. 12,248,026, issued on March 11, was assigned to SUBARU Corp. (Tokyo).
"Impedance measurement system" was invented by Tomohiro Abe (Tokyo).
According to the abstract* released by the U.S. Patent & Trademark Office: "An impedance measurement system configured to measure impedance of a measurement target capable of supplying power to an electrical load device includes one or more processors and one or more memories. The one or more processors are configured to perform a process including: acquiring data about output power from the measurement target when an alternating current signal of at least one frequency is superimposed on the output power; calculating impedance at the at least one f...
