Thus, the present invention has a merit of enabling a quicker and more accurate detection of a wireless power receiver."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-coil wireless charging method and device and system therefor","description":"The present invention relates to a multi-coil wireless charging method and a device and a system therefor, a wireless power transmitter for wirelessly transmitting power to a wireless power receiver, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10498163","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.
