As the temperature is maintained at a known target temperature, any variation in the duty cycle or range of duty cycles expected to maintain the target temperature is indicative of abnormal conditions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device and method for controlling an electrical heater to limit temperature","description":"There is provided a method of controlling an electrical heating element, including maintaining a temperature of the heating element at a target temperature by supplying pulses of electrical current to","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9713345","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.
