    • An apparatus for measuring distance in the game of golf includes an electro-mechanical DriveGauge.TM. which is provided with a large, easy-to-read display and which registers the player's strides in yards. The apparatus is preferably contained in an attractive housing having a belt clip and the display is mounted "upside down" so that the player may read the display without removing the apparatus from his/her belt. A large prominently colored reset button is preferably provided adjacent to the display so that the display may be quickly and easily reset to zero after a measurement is noted by the player. According to a presently preferred embodiment of the invention, an electromechanical transducer is coupled through a noise filter to a counter which is coupled through a display control and driver to a large four digit LCD display. A clock oscillator is coupled to a system clock unit which provides clock signals for the noise filter and the display control and driver. A stride register is set by a setting unit and provides output to the counter. The noise filter prevents extraneous mechanical vibration of the unit from registering as a player's stride. The LCD display preferably displays up to 999.9 yards in increments of 0.1 yards. In order to set the stride register, the player inputs the distance in feet using the setting unit using a single button which is pressed repeatedly, each press representing 0.1 feet.
    • 用于测量高尔夫游戏中的距离的装置包括一个机电式DriveGauge TM,其具有大的易于阅读的显示并且将玩家的步幅登记在场内。 该装置优选地容纳在具有带夹的有吸引力的壳体中,并且显示器被“倒置”安装,使得玩家可以在不从他/她的皮带上移除装置的情况下读取显示器。 优选地,与显示器相邻地设置大的显着颜色的复位按钮,使得在玩家注意到测量之后,显示器可以快速且容易地重置为零。 根据本发明的当前优选实施例,机电换能器通过噪声滤波器耦合到计数器,计数器通过显示控制和驱动器耦合到大的四位数字LCD显示器。 时钟振荡器耦合到系统时钟单元,其为噪声滤波器和显示器控制和驱动器提供时钟信号。 步进寄存器由设置单元设置,并向计数器提供输出。 噪音过滤器可以防止装置的外部机械振动作为玩家的步幅进行注册。 LCD显示屏最好显示最多999.9码,增量为0.1码。 为了设置步幅登记,玩家使用设置单位以英尺输入距离,使用重复按下的单个按钮,每个按钮代表0.1英尺。
