  • Gyroscope and fabrication process
    Patent number: 11548805
    Abstract: Gyroscopes are sensors that measure angular rate and angular orientation. A three-dimensional fused silica micro shell rate-integrating gyroscope is presented. One aspect of the gyroscope includes the use of optical sensors to detect motion of the resonator. The proposed gyroscope is attractive because it achieves several magnitudes higher accuracy as well as high vibration and shock insensitivity from a novel resonator design as well as other unique manufacturing processes.
    Type: Grant
    Filed: December 23, 2019
    Date of Patent: January 10, 2023
    Assignee: The Regents of the University of Michigan
    Inventors: Khalil Najafi, Jae Yoong Cho, Ali Darvishian, Guohong He, Behrouz Shiari, Tal Nagourney
