摘要： A tilt predictor incorporated into a total station to predict the degree of tilt of the rotational alidade portion of a total station corresponding to the rotational orientation of the rotational alidade portion. In one embodiment, the present invention defines the plane of rotation for the rotational alidade portion with the rotational alidade portion disposed in a first rotational orientation. The rotational alidade portion is then rotated to the desired rotational orientation. This embodiment then predicts the degree of tilt of the rotational alidade portion at the desired rotational orientation.

摘要： A leveling rod for an electronic level has a plurality of bar-shaped marks disposed adjacent each other in a longitudinal direction along the leveling rod in parallel with each other and perpendicular to a length of the leveling rod. The marks are arranged at a constant pitch. The width dimensions of the marks in the longitudinal direction of the leveling rod are represented by a plurality of integers. A permutation of predetermined number of values chosen from a sequence of numbers made up of a sequential array of the ratios of the width dimensions is arranged to be different from a permutation chosen from any other portion of the sequence of numbers.
