ALEXANDRIA, Va., Aug. 25 -- United States Patent no. 12,719,338, issued on Aug. 25, was assigned to Schenck RoTec GmbH (Darmstadt, Germany).
"Method for measuring the rotor angle-based expansion of a rotating rotor under centrifugal stress" was invented by Matthias Hartnagel (Alsbach-Haehnlein, Germany).
According to the abstract* released by the U.S. Patent & Trademark Office: "In a method for measuring the expansion of a rotating rotor on the basis of the rotor rotational speed, a first distance sensor is arranged at a distance to the rotor surface, the distance sensor contactlessly detecting the distance between the rotor surface and the first distance sensor in a time-based manner and generating first time-based electric distance sign...
