The drive circuit includes a controller configured to receive a closure signal from the sensor, determine a closing time of the solenoid valve based on the closure signal, determine a time delay between de-energizing the coil and the determined closing time, and determine a fluid flow value of fluid flowing through the solenoid valve based on the determined time delay."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Drive circuit for estimating fluid flow based on valve closure time and fluid application system including same","description":"A drive circuit for a solenoid valve having a coil and a poppet configured to translate within the coil includes a drive switch operable to de-energize the coil to translate the poppet toward a closed","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11998934","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.
