An overcurrent limiting circuit is configured to limit a first portion of the signal to prevent a false call for operation of the control. The overcurrent limiting circuit is further configured not to limit a second portion of the signal to prevent a false call, where the control is configured to recognize only the first portion as determinative of whether the signal is a call for operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and methods for power stealing by controllers","description":"A controller for use in a climate control system includes a power stealing circuit connectible with a control of the climate control system and configured for stealing power via a signal from a power ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9841203","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.
