The joint portion is present on one side and the other side with respect to the assumed crack C in a direction intersecting the assumed crack C."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Crack detection device","description":"A crack detection device for detecting a crack that occurs in a structure, includes: an MI cable that includes a metal sheath and a conductive wire accommodated in the metal sheath via a mineral insul","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11467111","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.
