An electronic circuit makes a first mode measurement using the first drive winding and a second mode measurement using the second drive winding. The absolute position in a range TC is computed from both modes' measurements. The sensor may be as compact as the incremental sensor it replaces, as the scale pattern and second drive winding needed for making it absolute do not need extra space."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inductive absolute position sensor","description":"An inductive absolute position sensor has a scale with planar conducting features on a pattern repeating every spatial period TC along a measuring path and a reading head with planar windings: multipo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11262219","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.
