The device also is configured to determine when the near field communication transaction is occurring; a memory configured to store a replacement sound; and a selection circuit coupled with the transceiver and the memory to select the replacement sound when the near field communication transaction is occurring and select the first frequency modulated audio signal when the near field communication transaction is not occurring. There is also a signal path coupled with the selection circuit and configured to provide a second frequency modulated signal based on the selection circuit. In this way, the replacement sound is the audio output when the NFC transaction is occurring and the regular audio is output when the NFC transaction is not occurring."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Near field communication and frequency modulation coexistence concealment system and method","description":"A system for determining a frequency modulated audio output of a mobile communication device during a near field communication transaction includes a transceiver providing a first frequency modulated ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8472873","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.
