ALEXANDRIA, Va., Oct. 21 -- United States Patent no. 12,771,213, issued on Oct. 20.
"Circuit for recapturing magnetic energy" was invented by Ryan Mark Thompson (Owatonna, Minn.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A circuit for recapturing magnetic energy is provided. When a magnet approaches a coil, a switching circuit may activate an electrical path to direct current from a power source through the coil. When the magnet moves away from the coil, the switching circuit may deactivate the electrical path to substantially decrease current from the power source to the coil, a magnetic field induced in the coil may at least partially collapse, and energy from the at least partially collapsing magnetic...
