The systems and methods are useful for, among other things, monitoring diffusion of fluids through porous materials, such as tissue samples."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Accurately calculating acoustic time-of-flight","description":"The subject disclosure presents systems and computer-implemented methods for determining an acoustic time-of-flight (TOF) of sound waves through a sample material with greater accuracy and in a more r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11971387","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.
