    • A distance measuring device and method are disclosed for use on a golf course. A satellite navigation system receiver determines a user's location. A database containing stored coordinates is accessed by a processor to determine a golf course and a hole associated with the location and a maximum and a minimum distance from the location to a green containing the hole. A laser rangefinder determines a distance between the location and each of a plurality of objects. The processor discards object distances which are not within the perimeter of the green. Optionally, an accelerometer and a gyrometer are used to more precisely determine a heading of the laser pulse for each object distance. The processor establishes from the stored coordinates a cone of interest originating at the location and extending to the green, and discards object distances which do not have headings within the cone of interest. The retained distance may be displayed for the user.
    • 公开了一种用于高尔夫球场的距离测量装置和方法。 卫星导航系统接收器确定用户的位置。 包含存储的坐标的数据库由处理器访问以确定高尔夫球场和与该位置相关联的孔以及从该位置到包含该孔的绿色的最大和最小距离。 激光测距仪确定位置与多个对象中的每一个之间的距离。 处理器丢弃不在绿色周边的物体距离。 可选地,使用加速度计和陀螺仪来更精确地确定每个物体距离的激光脉冲的航向。 处理器从存储的坐标建立起始于该位置并延伸到绿色的感兴趣的锥体,并丢弃在感兴趣的锥体内没有标题的物体距离。 可以为用户显示保留的距离。

    • A mass spectrometer having a mass filter which applies a transient voltage profile to accelerate ion packets. The voltage profile is chosen to have a functional form which imparts each ion species with a kinetic energy which is larger the larger the mass-to-charge ratio and a velocity which is smaller the larger the mass-to-charge ratio. The ions are detected in an ion detector which discriminates between different ion species based on their kinetic energy and taking account of the functional form of the voltage profile. Suitable voltage profiles include periodic functions such as sinusoids, triangles and sawtooths, which allow the amplification of drive pulses in the mass filter to be carried out with narrow band amplification stages, which are simple and inexpensive to construct.
    • 具有质量过滤器的质谱仪,其施加瞬态电压分布以加速离子包。 电压分布被选择为具有赋予每个离子种类具有较大质量 - 电荷比越大的动能的功能形式,并且质量与电荷比越大的速度越小。 在离子检测器中检测离子,其基于它们的动能鉴别不同的离子种类,并考虑到电压分布的功能形式。 合适的电压曲线包括诸如正弦曲线,三角形和锯齿的周期性函数,其允许通过窄带放大级来进行质量滤波器中的驱动脉冲的放大,这是简单且便宜的构造。
