Patent number: 11846508Abstract: A microelectromechanical gyroscope comprising first, second, third and fourth Coriolis masses, arranged in that order on an x-axis. In the primary oscillation mode, the Coriolis masses are configured to oscillate so that the second and third Coriolis masses move in linear translation along the x-axis away from a center point when the first and fourth Coriolis masses move in linear translation along the x-axis towards the first center point, and vice versa. When the gyroscope undergoes rotation about a y-axis which is perpendicular to the x-axis, the Coriolis masses are configured to oscillate so that the first, second, third and fourth Coriolis masses undergo vertical motion in a z-direction, wherein the first and third Coriolis masses move up when the second and fourth Coriolis masses move down, and vice versa.Type: GrantFiled: April 27, 2021Date of Patent: December 19, 2023Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Anssi Blomqvist, Ville-Pekka Rytkönen

Patent number: 11796561Abstract: The present invention relates to capacitive micromechanical accelerometers, and in particular to acceleration sensors with movable rotors which may rotate out of a substrate plane when the accelerometer undergoes movement with an acceleration component perpendicular to the substrate plane. The capacitive micromechanical accelerometer includes additional damping springs to reduce unwanted movement of the rotor in the substrate plane, thereby reducing the parasitic capacitance that results from motion of the rotor in the substrate plane. The damping springs are vertically recessed with respect to other components of the accelerometer in order to minimise the effect of the damping springs on movement of the rotor out of the substrate plane.Type: GrantFiled: August 3, 2022Date of Patent: October 24, 2023Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Akira Konno, Yoshitaka Kato, Ville-Pekka Rytkonen
