 * Records a three dimensional vector indicating acceleration along each device axis, not including gravity. All values have units of m/s^2. The coordinate system is the same as is used by the acceleration sensor.  
 * The output of the accelerometer, gravity and linear-acceleration sensors obey the following relation:
 * acceleration = gravity + linear-acceleration
