Each heating element is provided with two control paths, for example a relay and a triac connected in series with the heating element and a power supply. Each heater element has one control path connected to a first one of the processors and at least one heating element has at least one control path connected to a second one of the controllers. A hardware watchdog monitors the operation of the first processor, and can be triggered by a signal from the second processor, in response to which it can disable all heating elements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Redundant power control for respiratory system heaters","description":"A humidification system is provided for a respiratory system is provided with a controller having two processors that monitor the operation of each other and of heating elements in the respiratory sys","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8511305","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.
