A permanent magnet can be used instead of the electromagnetic coil and associated driving energy source. A precise displacement measurement is given by a mathematical function (such as the ratio or difference) of the two magnetic sensors demodulated signals. The displacement sensor can be mounted on a maneuverable C-frame to monitor the caliper of anodes and cathodes produced for lithium ion batteries."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High accuracy and high stability magnetic displacement sensor in the presence of electromagnetic interferences","description":"An accurate and stable displacement sensor that reads through coated metal substrates achieves better than one micron accuracy includes: an electromagnetic coil positioned in a first enclosure; (ii) m","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11519710","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.
