    • The apparatus is for simultaneously sensing vertical/horizontal rotational angles for 3 dimensional moving object just by using one sensor. It comprises a metallic tetrahedron structure supporting the piezoelectric sensor; triangular piezoelectric sensors adhering to 4 right triangular side faces of the tetrahedron structure; a rectangular piezoelectric sensor adhering to the rectanglular bottom face of the tetrahedron structure; a signal generator sending sigals to the rectangular sensor; differential amplifiers amplifying the signals of the piezoelectris sensors; a detector prosessing the vector addition of the sensed signals.
    • 该装置用于仅通过使用一个传感器同时感测用于三维移动物体的垂直/水平旋转角度。 它包括支撑压电传感器的金属四面体结构; 三角形压电传感器附着在四面体结构的4个右三角形侧面; 固定在四面体结构的正方形底面的矩形压电传感器; 信号发生器将信号发送到矩形传感器; 差分放大器放大压电传感器的信号; 一种检测器,用于检测感测信号的矢量加法。
