    Abstract: Navigation systems and methods for autonomous vehicles are provided. The navigation system may include multiple navigation subsystems, including one having an inertial measurement unit (IMU). That unit may serve as the primary unit for navigation purposes, with other navigation subsystems being treated as secondary. The other navigation subsystems may include global positioning system (GPS) sensors, and perception sensors. In some embodiments, the navigation system may include a first filter for the IMU sensor and separate filters for the other navigation subsystems.

    Abstract: According to some aspects, there is provided a microelectromechanical systems (MEMS) device wherein one or more components of the MEMS device exhibit attenuated motion relative to one or more other moving components. The MEMS device may comprise a substrate; a proof mass coupled to the substrate and configured to move along a resonator axis; and a first shuttle coupled to the proof mass and comprising one of a drive structure configured to drive the proof mass along the resonator axis or a sense structure configured to move along a second axis substantially perpendicular to the resonator axis in response to motion of the proof mass along the resonator axis, wherein displacement of at least a first portion of the proof mass is attenuated relative to displacement of the first shuttle and/or a second portion of the proof mass.

    Abstract: Micromachined inertial devices are presented having multiple linearly-moving masses coupled together by couplers that move in a linear fashion when the coupled masses exhibit anti-phase motion. The couplers move in opposite directions of each other, such that one coupler on one side of the movable masses moves in a first linear direction and another coupler on the opposite side of the movable masses moves in a second linear direction opposite the first linear direction. The couplers ensure proper anti-phase motion of the masses.

    Abstract: A MEMS device is provided comprising a substrate; a proof mass coupled to the substrate and configured to move along a resonator axis; a drive structure comprising at least one electrode and configured to drive the proof mass to move along the resonator axis; and a pivoting linkage coupled to the proof mass at first and second ends of the pivoting linkage, the first end comprising a first fixed pivot and the second end comprising a second fixed pivot, the pivoting linkage comprising: a first bar configured to pivot about the first fixed pivot and a first dynamic pivot; a second bar configured to pivot about the second fixed pivot and a second dynamic pivot; and a third bar configured to pivot about the first dynamic pivot and the second dynamic pivot, wherein the proof mass moves along the resonator axis when the pivoting linkage pivots.
