Patent number: 11125772Abstract: Motion and/or orientation sensing systems can utilize gyroscopes, accelerometers, magnetometers, and other sensors for measuring motion or orientation of connected objects. Temperature changes affect the precision of the data output by the motion/orientation sensing device. A system is provided for controllably heating a device within a package to a desired temperature that varies based on the ambient temperature. The operating temperature of the device can then be known and controlled. The ambient temperature can be known through an ambient temperature sensor, for example. Given this information, a controller compensates the data output by the device to further improve the accuracy in the measurements. Like the amount of heating provided to the package, the amount of compensation is also based on the ambient temperature and/or the device temperature.Type: GrantFiled: July 2, 2019Date of Patent: September 21, 2021Assignee: BLILEY TECHNOLOGIES, INC.Inventors: Jay Mitchell, Anthony Challoner, Sangwoo Lee

Patent number: 10670423Abstract: A MEMS (Microelectromechanical System) INU (Inertial Navigation Unit) chip comprises a compact autonomous device undergoing motion tracks and analyzes its definite movement relative to local Earth coordinates with optimal accuracy and repeatability of lmm over distances of greater than two meters. The MEMS INU includes an Inertial Motion Tracking Device (IMTD) comprises a gyroscope, accelerometer, magnetometer, and digital processor programmed with a general purpose Inertial Measurement Engine (IME), an application specific Motion Analysis and Adaptation (MAA) program and a low power radio. The IMTD tracks its motion with optimum accuracy using compact practical sensors that may have noise and drift by periodically and autonomously checking its velocity changes at an optimum interval, computing a linear acceleration therefrom and determining a no-motion or motion condition relative to a threshold and correcting its velocity, position and acceleration errors when there is no motion.Type: GrantFiled: April 29, 2019Date of Patent: June 2, 2020Assignee: InertialwaveInventors: Anthony Dorian Challoner, Byron Campbell Challoner, Jeremy Daniel Popp

Patent number: 10527419Abstract: A compact Inertial Wave Angle Gyroscope (IWAG) is operated using a phase lock loop to track resonator phase and a baseband regulator to null quadrature. The resonator velocity or its components computed from precession angle are first determined at baseband and then applied to gain matrices in order to generate the feedback control forces for self-precession, cancellation of damping and compensation of anisodamping. The inertial rotation input is determined from the measured total precession angle by removing the computed or calibrated self-precession angle. The resonator energy can be regulated to a fixed magnitude and the baseband feedback force for self-precession at a fixed rate determined from components computed from precession angle such that the total force is in phase with baseband velocity but has fixed magnitude. The IWAG inertial rotation input can be determined from the measured total precession rate by removing the computed self-precession rate.Type: GrantFiled: February 17, 2017Date of Patent: January 7, 2020Assignees: Inertialwave, The Regents of the University of CaliforniaInventors: Anthony Dorian Challoner, Parsa Taheri-Tehrani, David Horsley
