Autocalibration of MEMS Accelerometer

2006 IEEE Instrumentation and Measurement Technology Conference Proceedings, 2006
In this paper a new approach of an auto calibration method for micromechanical sensors is proposed. In particular, recalibration of acceleration sensors without any additional laboratory equipment is considered. If the device is stationary, the proposed procedure exploits the fact that the output vector of the acceleration sensor should match the ...

Translational accelerometer and accelerometer assembly method

The Journal of the Acoustical Society of America, 1990
An accelerometer comprising a body (10, 16, 12), a proof mass (18, 30, 32), a mounting strucutre comprising flexures (20, 22) for mounting the proof mass to the body, and force sensing elements (34, 38). The flexures permit translational motion of the proof mass with respect to the body along a sensitive axis SA and rotation of the proof mass with ...

Accelerometer and angular accelerometer

The Journal of the Acoustical Society of America, 1996
An accelerometer includes a main body, a displacing member, a scale, and a detecting unit. The displacing member is attached to the main body and has a displacing portion displaced relative to the main body at least in a direction of acceleration measurement in accordance with a force applied.

Working with the Accelerometer

2010
An accelerometer has many practical uses for applications that depend on the movements of a Windows Phone in three-dimensional space. With data from an accelerometer, you can steer a simulated car in a driving game or fly a plane in a flight simulator.
