But we found the product yield was poor for vertical resonating structure such as Z-axis accelerometer and switch.
但该工艺用于制造垂直动作结构如Z轴加速度计和开关时，成品率不高。
Use your device as a builder's level. Level Touch features both horizontal and vertical bubble tubes. Readings are based on device's built-in accelerometer.
可以使用你的手机当做一个水平仪， 看看相框挂的歪不歪，一碗水端的平不平，总之应该是可以用得着的地方。
With the estimation of the zero drift of accelerometer, the precision of the vertical velocity and height can be improved and the measurement of the acceleration can be got without zero drift.
该滤波器能够有效滤除海浪杂波的干扰，获得高质量的高度信号和垂向速度信号。
