The control circuit applies a test signal, generated based on voltage from the battery, to the contact circuit at a second timing arriving at shorter intervals than the first timing, acquires a detection signal indicating current flow in the contact circuit due to test signal application, and regardless of the first timing, operates the communication circuit when the detection signal is acquired to transmit to the external apparatus that the state of a device connected to the contact circuit is abnormal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"State detection apparatus","description":"A state detection apparatus includes a communication circuit that transmits information to an external apparatus, a control circuit that operates the communication circuit at a first timing, a battery","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11977101","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.
