The power feed cable is connected to the AC power source. The power reception pickup is provided on a traveling vehicle and arranged to receive electric power through the power feed cable in a contactless fashion. The magnetic field reducing section includes a coil antenna and a capacitor. An induced electric current flows in the coil antenna due to a magnetic field generated by an electric current flowing in the power feed cable. A resonance relationship is established between the coil antenna and the capacitor such that the induced electric current in the coil antenna is out of phase or in opposite phase with the electric current flowing in the power feed cable."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Traveling vehicle system","description":"A contactless power feed type traveling vehicle system prevents and minimizes leakage of the magnetic field from a power feed cable and includes an AC power source, a power feed cable, a power recepti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8519570","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.
