    • Disclosed herein are representative embodiments of grade rods, grade-rod readers, and combinations thereof. In one exemplary embodiment, a grade rod is provided that has a reference surface extending along at least a portion of the rod. The reference surface includes two or more reference indicators spaced at substantially even intervals from one another. A reader unit is mounted to the rod (for example, slidably mounted). The reader unit includes one or more sensors positioned proximate to at least a portion of the reference surface of the rod. The sensors of this embodiment are configured to detect the motion of at least one of the two or more reference indicators relative to the sensors as the reader unit is moved along the reference surface. Other grade rod and grade-rod reader embodiments, as well as methods for using such embodiments, are also disclosed.
    • 本文公开了等级棒,等级棒读取器及其组合的代表性实施例。 在一个示例性实施例中,提供了具有沿杆的至少一部分延伸的参考表面的坡度杆。 参考表面包括两个或更多个以彼此间隔几乎均匀间隔的参考指示器。 读取器单元安装到杆(例如,可滑动地安装)。 读取器单元包括靠近杆的参考表面的至少一部分定位的一个或多个传感器。 该实施例的传感器被配置为当读取器单元沿着参考表面移动时,相对于传感器检测两个或更多个参考指示符中的至少一个的运动。 还公开了其它级棒和级棒读取器实施例,以及使用这些实施例的方法。

    • A self aligning baseline instrument including a first light assembly operable to generate a first vertical light plane, a second light assembly operable to generate a second vertical light plane at a predetermined angle to the first vertical light plane, a third light assembly operable to generate a first horizontal light plane that is perpendicular to the first and second vertical light planes, and a fourth light assembly operable to generate a vertical plumb light beam that defines a reference point on an underlying surface, the vertical light beam parallel to and coincident to the center axis of the instrument. The first and second vertical light planes and fourth plumb laser beam all intersect together through the center axis of the instrument.
