The power supply electrode is formed of a plurality of segment electrodes which are arranged in a line in a moving direction of the movable portion and to which power is individually supplied from the high-frequency power source circuit. A plurality of switches are connected between the high-frequency power source circuit and the segment electrodes, respectively, and are opened and closed independently of one another. A current detecting circuit individually detects segment currents flowing in the respective segment electrodes; and a switch controller controls the switches so that only a part of the plurality of switches are closed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electrostatic-coupling contactless power supply device","description":"An electrostatic-coupling contactless power supply device includes a power supply electrode and a high-frequency power source circuit that are provided on a fixing portion, and a power receiving elect","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9831720","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.
