An upper surface of the cover has a first inclining portion inclining toward the first foreign-matter-detecting unit. The power control circuit transmits power through the plane coil if a foreign matter is not detected in the no-wire portion based on an output from the first foreign-matter-detecting unit. The power control circuit is configured to stop transmitting power through the plane coil if foreign matter is detected in the no-wire portion based on an output from the first foreign-matter-detecting unit. This power transmission coil is capable of detecting a small foreign matter that may generate heat."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power transmission coil","description":"A power transmission coil includes a plane coil including a no-wire portion and a coil wound about a no-wire portion, a cover for covering the plane coil from above, a first foreign-matter-detecting u","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9741488","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.
