The second substrate is a multilayer substrate that includes a first layer provided with a ground pattern and a second layer provided with a power supply pattern, and includes slit portions where the patterns are not present as viewed from a direction of the central axes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless power transfer system, power reception apparatus, and control method therefor","description":"A wireless power transfer system includes: (a) an annular first substrate, a first coil, a second coil, and an annular second substrate that are stacked such that central axes of those substantially c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11239700","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.
