    • A golf practice device comprising a mat with at least two sensors arranged therein in the direction of a swing orbit of a head of a golf club. A swing time substantially from a start of a back swing to a point of an impact with a golf ball is calculated in response to signals output by the sensors, and the result is indicated so that a golfer can observe same and thus achieve a stable swing. It is possible to distinguish an address motion and an actual swing before impact by adapting a special combination of the outputs of the two sensors.
    • 一种高尔夫球练习装置,包括具有至少两个传感器的垫,所述传感器布置在高尔夫球杆的头部的摆动轨道的方向上。 根据由传感器输出的信号,计算大体上从后摆开始到高尔夫球的冲击点的摆动时间,并且指示结果,使得高尔夫球手可以观察到相同的状况,从而实现稳定的摆动 。 通过适应两个传感器的输出的特殊组合,可以区分地震运动和冲击前的实际摆动。
