ALEXANDRIA, Va., Feb. 24 -- United States Patent no. 12,559,343, issued on Feb. 24, was assigned to Otis Elevator Co. (Farmington, Conn.).
"Emergency terminal deceleration in elevator systems" was invented by Uwe Schonauer (Berlin).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method of controlling a moving component (22, 24) approaching a buffer (42, 46) in a hoistway (34) of an elevator system (20) is provided. The method includes: a) calculating, based on a current velocity of the moving component (22, 24), a required braking distance to decelerate the moving component (22, 24) to a maximum buffer impact velocity; b) comparing the required braking distance to a current buffer distance between the moving...
