Abstract
Apparatuses, methods and systems apparatus for sensing an orientation are disclosed. One apparatus includes an accelerometer, wherein the accelerometer generates a sensed acceleration of the accelerometer and a gyroscope, wherein the gyroscope generates a sensed orientation of the gyroscope. The apparatus further includes a first adaptive filter, the first adaptive filter operative to receive at least the sensed acceleration and the sensed orientation of the gyroscope, and generate a first orientation (Q) of the apparatus, a second adaptive filter, the second adaptive filter operative to receive at least the sensed acceleration and the sensed orientation of the gyroscope, and generate a second orientation (Q′) of the apparatus, wherein a tuning for the first adaptive filter is different than a tuning for the second adaptive filter.
