The housing has an inner surface, encompassing the inner cavity, which geometry and material composition selected to define a general propagation path for the predetermined electromagnetic radiation from the antenna arrangement towards a charging zone. The inner cavity of the housing operates as a waveguide for directionally guiding the electromagnetic radiation to the charging zone and providing substantially maximal intensity of the electromagnetic radiation within the charging zone."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless charging device","description":"The present invention provides wireless charging techniques and devices for charging electronic device(s) within a closed space defined by a substantially hollow housing containing an antenna arrangem","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9762081","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.
