INERTIAL MEASUREMENT UNIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18462922 titled 'INERTIAL MEASUREMENT UNIT
Simplified Explanation
The abstract describes an inertial measurement unit that includes sensors for measuring angular velocity and acceleration, a storage portion for storing correction parameters, a parameter control portion for selecting a correction parameter, and a correction calculation portion for correcting the inertial information using the selected parameter.
- Inertial measurement unit with sensors for angular velocity and acceleration
- Storage portion for storing correction parameters related to the range of values of the inertial information
- Parameter control portion for selecting a correction parameter from the stored parameters
- Correction calculation portion for correcting the inertial information using the selected parameter
Potential Applications
- Navigation systems for vehicles, aircraft, and drones
- Robotics and autonomous systems
- Virtual reality and augmented reality devices
- Motion tracking in sports and gaming
Problems Solved
- Inaccurate inertial measurements due to sensor errors and noise
- Difficulty in calibrating and adjusting the sensors for different operating conditions
- Limited range of values for which the sensors provide accurate measurements
Benefits
- Improved accuracy and reliability of inertial measurements
- Automatic correction of sensor errors and noise
- Flexibility in selecting the appropriate correction parameter for different operating conditions
Original Abstract Submitted
An inertial measurement unit includes an angular velocity sensor and an acceleration sensor that output inertial information, a storage portion that stores a plurality of correction parameters related to a range of values of the inertial information, a parameter control portion that selects a selection correction parameter from the plurality of correction parameters, and a correction calculation portion that corrects the inertial information using the selection correction parameter.
