    • There is provided a method of determining an estimate of the velocity of a device in a horizontal or vertical direction, the method comprising obtaining measurements of the acceleration acting on the device in three dimensions; using a first filter and the obtained measurements to estimate acceleration due to gravity; estimating the acceleration acting in a horizontal or vertical direction due to motion of the device using the estimated acceleration due to gravity; integrating the estimate of the acceleration acting in said direction due to motion of the device to give an estimate of velocity in said direction; and using a second filter to remove offset and/or drift from the velocity to give a filtered velocity; wherein at least one of the first filter and second filter is a non-linear filter. An apparatus configured to operate according to the above method is also provided.
    • 提供了一种在水平或垂直方向上确定装置的速度的估计的方法,所述方法包括获得在三维上作用在装置上的加速度的测量值; 使用第一过滤器并且获得的测量值来估计由重力引起的加速度; 估计由于使用由于重力引起的估计加速度的装置的运动而在水平或垂直方向上作用的加速度; 积分由于装置的运动而在所述方向上作用的加速度的估计,以给出所述方向上的速度估计值; 并且使用第二滤波器来从速度去除偏移和/或漂移以产生滤波的速度; 其中所述第一滤波器和所述第二滤波器中的至少一个是非线性滤波器。 还提供了一种根据上述方法进行操作的装置。
