Ellipsoid fitting algorithms are widely used to calibrate Magnetic Angular Rate and Gravity
(MARG) sensors. These algorithms are based on the minimization of an error function that …

Repetitive work in the stooped posture is a known risk factor for developing low back
disorders (LBDs); regardless, the stooped posture is widespread throughout the world in the …

A prior laboratory study found that when wearing a weight transfer device in the stooped
posture, trunk flexions were reduced, and subjects who did not experience flexion …

In order to build a tilt sensor having a desired sensitivity and measuring range, one should
select an appropriate type, orientation, and initial position of an accelerometer. Various …

The paper discusses thoroughly a problem of determining tilt over various measurement
ranges by measuring Cartesian components of the gravity acceleration with application of …

The paper addresses the problem of experimental studies of miniature tilt sensors based on
low-range accelerometers belonging to Microelectromechanical Systems (MEMS). A custom …

Motion capture using wireless inertial measurement units (IMUs) has many advantages over
other techniques. Achieving accurate tracking with IMUs presents a processing challenge …
