Beacons are scheduled to transmit independent of the location of listening devices in the system. Listening devices may receive multiple encoded radio frequency pulses (RF) prior to a single acoustic pulse, and then resolves which RF pulse corresponds to the acoustic pulse using triangulation techniques."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Geometrical scheduling algorithm for acoustic positioning beacons","description":"An improved active-beacon/passive-listener time difference of arrival navigation system that relies on the multiple beacons to transmit uncoded acoustic pulses of a same frequency that propagate in th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9716980","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.
