And, if it is confirmed that the DUB distribution table shows a specific distribution pattern corresponding to an acceleration sound, etc., the measuring apparatus makes a measured intensity to be identified as an intensity measured at a start position of a platform or a tunnel section, based on the time when the specific distribution pattern appears."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for measuring magnitude of radio wave along a subway line, and an apparatus for said method","description":"The measuring apparatus according to the present invention searches each of subbands divided from a target band set with respect to the Frequency Distribution Information (FDI) obtained periodically t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11469836","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.
