A joint resonance frequencies of a transmitter resonance circuit and a relay resonance circuit have a main resonance frequency (MRF). The transmitter is configured to operate at an operational frequency (OPF) from a range of OPFs. The range of OPFs is different than the MRF. The at least one relay comprises a second relay coil connected in series to the first relay coil. One side of the second relay coil faces the device and a second side of the second relay coil is covered by a relay ferrite layer. The second relay coil is smaller than the first relay coil."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System for wireless power charging","description":"A system for wirelessly charging, via a medium, a device having a receiver coil comprises at least one relay configured to inductively transfer power to the receiver coil of the device and a transmitt","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11482887","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.
