The master circuit sets one of first and second transmitting/receiving circuits for transmitting operation and the other for receiving operation according to a control signal, and detecting a leading edge and a falling edge of the control signal, transmits a pulse signal with the pulse interval changing after a predetermined period of time. The slave circuit detects the change of the pulse interval of the signal received through third and fourth transmitting/receiving circuits and according to the detection result, sets one of the third and fourth transmitting/receiving circuits for receiving operation and the other for transmitting operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal transmission device and switching power supply","description":"A signal transmission device of aspects of the invention can include a master circuit connected to the primary sides of first and second transformers and a slave circuit connected to the secondary sid","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9589720","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.
