ALEXANDRIA, Va., Nov. 18 -- United States Patent no. 12,473,821, issued on Nov. 18, was assigned to SCHLUMBERGER TECHNOLOGY Corp. (Sugar Land, Texas).
"Pre-loaded bearings for sensor shell" was invented by Julien Steimetz (Bristol, Great Britain).
According to the abstract* released by the U.S. Patent & Trademark Office: "Devices, systems, and methods for stabilizing a gyroscopic sensor include bearings supporting a MEMS-type gyroscope located in a shell. The shell rotates around a secondary shaft connected to an extension arm of a primary shaft. A biasing element pre-loads thrust bearings on either side of the shell against the extension arm, which can limit motion of the shell during operation of the sensor, thereby improving measuremen...
