ALEXANDRIA, Va., June 12 -- United States Patent no. 12,298,334, issued on May 13.
"System and method for determining the impedance properties of a load using load analysis signals" was invented by Essam Samir Elsahwi (Toronto).
According to the abstract* released by the U.S. Patent & Trademark Office: "Various embodiments are described herein for measuring the impedance properties of a load using load analysis signals. In one example embodiment, a transformer is provided which includes at least one primary winding, and at least one secondary winding. The at least one primary winding is coupled in series between a direct-current (DC) power supply and the load. A variable alternating-current (AC) voltage generator is coupled in-series to t...
