Accordingly, the facsimile device can reliably prevent a false detection of a noise that has a similar signal component to a CNG signal as a CNG signal. It is possible to prevent the facsimile machine from being automatically shifted to a facsimile receiving mode by the false detection of the noise."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication device","description":"When a facsimile device detects an audio signal via a CNG signal detection unit while detecting an OFF signal in a CNG signal during a telephone conversation, the facsimile device does not detect the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488206","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.
