    • An improved hand-held sensor having a recessed LED array for indicating the location of an object behind a wall surface. The array displays in an arrow shaped format the location of the sensor relative to the object. The LED's can be offset both laterally and in depth from the surface of the sensor exterior case and are recessed from the surface. The sensor includes a soft feeling slip-resistant gripping surface for the user. One form of the sensor includes a slide switch actuator, which is retained in one wall of the sensor case to enable actuation of a switch mechanism without physical loading on the switch mechanism.
    • 一种改进的手持传感器,其具有用于指示物体在壁表面后面的位置的凹陷LED阵列。 阵列以箭头形式显示传感器相对于物体的位置。 LED可以从传感器外壳的表面横向和深度偏移,并从表面凹陷。 传感器包括用于使用者的柔软感觉防滑握持表面。 传感器的一种形式包括滑动开关致动器,该致动器保持在传感器外壳的一个壁中,以便能够在开关机构上实现物理负载的情况下启动开关机构。

    • An ultrasonic distance measuring device for use, for instance, in the building trades, conventionally measures distance by projecting a sonic beam towards the target and detecting the reflection from the target. Also provided is an associated co-axial laser pointer which provides a visual indication of where the sonic beam is pointed. This laser pointer provides a laser beam which illuminates the target. However, the laser beam is not a typical laser beam, but instead is diffracted so that it covers an area at the target approximately the same size and shape as the area covered by the sonic beam. This provides a clear indication to the user that the sonic beam is not a single point beam but instead is possibly reflecting from any one of a number of points on the target. This provides a better indication to the user than does the single point beam of what possible locations are being measured on the target The laser beam pattern is, for instance, a circular area, a pattern of lines or rings, or a set of dots including a bright central dot.
    • 例如在建筑行业中使用的超声波距离测量装置通常通过将声束投射到目标并检测来自目标的反射来测量距离。 还提供了相关联的同轴激光指示器,其提供声波束指向的位置的视觉指示。 该激光指示器提供照射目标的激光束。 然而,激光束不是典型的激光束,而是被衍射,使得它覆盖目标处的区域与声波束所覆盖的区域大致相同的大小和形状。 这向用户提供了清晰的指示,即声波束不是单点波束,而是可能从目标上的多个点中的任何一个点反射。 这为用户提供比目标上测量可能位置的单点光束更好的指示。激光束图案例如是圆形区域,线或环的图案或一组点,包括 一个明亮的中心点。
