Calibration of a Three-Axis Accelerometer Unit on a Centrifuge

نویسندگان

چکیده

We focus on the problem of calibrating a three-axis accelerometer unit. If its sensors are intended to measure specific forces much stronger than Earth’s surface gravity, and if they also have significantly nonlinear characteristics, undergo calibration procedure centrifuge capable generating strong centripetal due rapid rotation. The generated force measured by accelerometers then depends relative geometry sensor proof masses axis Since rate rotation is very high, variations in coordinates smaller their own size become significant. This implies one cannot them directly, thus either estimate along with all other parameters, or exclude from equations. In addition, extra angular deformities that be directly arise under rotations. paper concerns observability issues appropriate estimation problem.

Noise and reliability measurement of a three-axis micro-accelerometer

A special measurement system is developed to measure the combined noise and reliability of a three-axis micro-accelerometer. Three parametric tests are provided: gravitational, thermal and acoustical. The measurements were performed on both the in-plane and the out-of-plane axes. The temperature-dependence and acceleration-dependence of the noise was found, in agreement and contrast to the theo...

"User Authentication Method and Implementation Using a Three-Axis Accelerometer"

The rapid growth of accelerometer use on consumer electronics has brought an opportunity for unique user authentication. We present an efficient recognition algorithm for such interaction using a single three-axis accelerometer. Unlike common user authentication methods which require memorizing complex phrases and are prone to physical attacks, our method requires a single training sample for a...
