Acoustic signals are received at the ultrasonic sensor over a time of flight range while a target is interacting with the ultrasonic sensor, wherein the acoustic signals include a primary signal contribution and a multipath reflection signal contribution. The characteristics of the multipath reflection signals are compared to received acoustic signals. The primary signal contribution of the received acoustic signals is determined at a plurality of times of flight of the time of flight range based on the characteristics of the multipath reflection signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multipath reflection correction","description":"In a method for multipath reflection correction of acoustic signals received at an ultrasonic sensor, characteristics of multipath reflection signals of the ultrasonic sensor are accessed, wherein the","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11995909","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.
