  • Publication number: 20190169979
    Abstract: An instrument package for use during the drilling a wellbore. The instrument package includes a plurality of instruments such as accelerometers, gyroscopes, and magnetometers; a computer is configured to determine the current position of the plurality of instruments from a set of measurements produced by the plurality of instruments; and wherein the plurality of instruments are mechanically isolated from a drill head assembly by one or more multi-degree of freedom vibration isolators. The computer preferably has at least two modes different analytical modes of analyzing the set of measurements produced by the plurality of instruments, including a continuous mode and a survey mode, the continuous mode being operational during times that active drilling is occurring and the survey mode being operational during times that the active drilling is not occurring.

  • Patent number: 9991868
    Abstract: A micro-resonator employs a lid-integrated electrode to one or more of drive, sense and tune a vibrational resonant mode of a microelectromechanical systems (MEMS) resonator. The micro-resonator includes a lid attached to a base that provides a resonator cavity. The micro-resonator further includes the MEMS resonator extending from a surface of the base toward the lid within the resonator cavity. The lid-integrated electrode extends vertically from the lid into the resonator cavity toward the base. The vertically extending, lid-integrated electrode is positioned spaced from and adjacent to a side of the MEMS resonator to one or more of drive, sense and tune mechanical movement of the MEMS resonator.
