A coupler including the first and second electrodes and the first inductor forms one resonant circuit and a coupler including the third and fourth electrodes and the second inductor forms another resonant circuit. Resonance frequencies of the couplers are substantially equal. The first and second electrodes and the third and fourth electrodes are spaced apart by λ/2π or less."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless power transmission system for transmitting power between a power transmitting device and a power receiving device","description":"A wireless power transmission system that transmits alternating-current power includes a power-transmitting device including first and second electrodes spaced apart and having a total width of λ/2π o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9824817","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.
