NFC Detector Network for Implantable Medical Devices

The patent extracts only the essential NFC detection function from a full NFC integrated circuit. Instead of implementing complete NFC protocol processing capability, the invention uses a simplified detector that only needs to sense the presence of an NFC signal at 13.56 MHz and generate a wakeup indication, leaving out all complex data processing functions.

The patent applies local quality by creating a specialized NFC detector with properties tailored specifically for signal presence detection rather than general-purpose NFC communication. The detector is designed with specific characteristics (frequency tuning to 13.56 MHz, simple envelope detection) that are locally optimized for its specific function of triggering BLE wakeup, rather than having uniform capabilities across all NFC functions.

The patent implements dynamics by making the BLE transceiver's operational state changeable rather than fixed. The transceiver dynamically transitions between sleep mode (low power) and active mode (high power) based on external conditions. The NFC detector acts as a trigger that causes the BLE transceiver to transition from sleep to active state only when needed, creating a dynamic power management system.

The patent applies periodic action by having the BLE transceiver operate in cycles of sleep and activity rather than continuous operation. The NFC detector periodically checks for incoming NFC signals and triggers BLE activation only when signals are present, creating a periodic wake-up pattern that reduces overall power consumption while maintaining communication availability when needed.
