THREE DIMENSIONAL MOTION SENSOR BY USING THE OSCILLATING WEIGHT

摘要

The present invention includes: a sensor in a spherical shape, a disk, and a rotational weight inside the sensor. The disk and the rotational weight are connected to a connection rod. The disk and the rotational rod within the sensor maintain a location under the influence of gravity, and an electrode is formed on the sensor. The location of the disk or the rotational weight is sensed through the electrode. When accurately and easily measuring the direction of motion in a simple structure by sensing the variations of a three-dimensional posture (movement direction, rotational direction, and rotational angle, etc.) of an object, a more accurate sensor value is obtained by efficiently preventing irregular motion of fluid which causes an error.
