The operational status of the pump is monitored by monitoring the condition of a switch associated with the pump which is adapted to change state when the pump piston is withdrawn into its pump housing as a proper reaction of the pump to its drive signal and return to its original state when the pump piston is no longer withdrawn. The state condition of the of the switch is used to confirm proper pump operation in drawing the breath sample into the chamber; if proper pump operation is confirmed, the breath sample can be accepted for further processing and analysis."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Breath sampling methodology having improved reliability","description":"An improved method of breath sampling, particularly adapted for use in connection with motor vehicle alcohol breath monitoring devices, comprises the sending of a drive signal to a piston pump to draw","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8505360","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.
