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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic level and leveling rod for electronic level","description":"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 patt","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8510964","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
