The voltage applying unit applies an AC voltage to both ends of each of the first series connection body and the second series connection body. The processing unit performs a process for detecting the metal object on the basis of a potential difference between a connection point included in the first series connection body and a connection point included in the second series connection body."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Metal object detection device","description":"A metal object detection device includes a plurality of detection coils, a capacitor configuring a resonant circuit in cooperation with each of at least two of the detection coils, a first series conn","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9841524","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.
