20130152413 | ELECTRONIC LEVEL AND LEVELING ROD FOR ELECTRONIC LEVEL - A leveling rod for electronic level for easily expanding a measurable range for long/short distance measurements without inaccuracy even when mixed and used with a conventional level, has a first pattern having a grayscale of predetermined rules for a first distance range measurement, and a second pattern enlarged/reduced with respect to a pattern with the inverted grayscale of the first pattern for a second distance range measurement different from the first distance range. An electronic level includes a height measuring device measuring a collimation point height from an output signal from a line sensor for correspondence to the first pattern, a grayscale inverting device inverting the grayscale of the output signal from the line sensor for correspondence to the second pattern, and a height correcting device correcting the height measured by the height measuring device according to a reduction scale of the second pattern with respect to the first pattern. | 06-20-2013 |
20120285027 | ELECTRONIC LEVEL - Provided is an electronic level capable of accurately measuring a height difference between two points even when a waving method of finding and determining as a measured height a minimum value of read heights while rocking a leveling rod back and forth is used. An electronic level includes leveling rod reading-in means (S | 11-15-2012 |
