An angle calculation unit calculates a first rotation angle θ of a rotating magnet based upon the strengths of the output signals from the first Hall element pair and the second Hall element pair, and calculates a second rotation angle θc of the rotating magnet based upon the strengths of the output signals from the third Hall element pair and the fourth Hall element pair."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotation angle measurement apparatus","description":"A rotation angle measurement apparatus includes: a first Hall element pair for detecting a magnetic component in a first direction; a second Hall element pair for detecting a magnetic component in a s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9625278","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.
