The parameters of the low-pass behavior are determined in direction-dependent fashion by minimizing direction-dependent error signals created by high-pass filtering and logical combination with direction-dependent saturation characteristic curves, the direction-dependent error signals being calculated by comparing the modeled and the measured signal for a rising and a falling signal component."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for dynamic monitoring of gas sensors","description":"In a method for monitoring the dynamics of gas sensors of an internal combustion engine, which gas sensors exhibit a low-pass behavior as a function of geometry, measurement principle, aging, or conta","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9704306","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.
