The valve controls the flow of incoming breath between two flow paths: a venting path through which breath exits the device without passing by the nanoparticle sensor, and a sensing path that includes the nanoparticle sensor. In some embodiments, the valve is controlled by a processor that monitors pressure produced by the user's exhalation force. Based on these real-time pressure measurements, the processor adjusts the valve to maintain the pressure, and thus the flow rate, in the sensing path within a desired range. The processor may also use the pressure measurements to determine whether the characteristics of the user's exhalation are sufficient to generate a valid measurement."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Breath analysis device with regulated flow during exhalation","description":"A pump-less breath analysis device regulates the flow of breath past a nanoparticle sensor (or other semiconductor sensor) by dynamically adjusting the state or position of a valve as the user exhales","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11497414","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.
