Near-Field Systems Using Receivers TRIZ Cases
- Resonance Circuit Frequency Control for Stable RFID Voltage
Dynamic frequency tuning maintains stable operation across varying distances, preventing excessive voltage and heat generation without clamping circuits.
- NFC Antenna Module Resonance Tuning and Detachable Design
A detachable NFC antenna module uses a resonance unit to set operating frequency for efficient wireless communication.
- Electric Field Communication via Metal Medium
Metal communication medium transmits electric fields between electrodes, resolving cable wear and ambiguous signal discrimination in heavy machinery monitoring.
- Near Field RF Communicator Digital Modulation
A near field RF communicator replaces complex analog driver circuitry with a digital signal selector generating multi-level sine waves to simplify modulation.
- Flexible Antenna Capacitor Design for Implanted Sensor Data
A flexible antenna system with integrated capacitors communicates with implanted sensors to collect physiological data.
- NFC Device Symmetrical Filter Configuration for Harmonic Noise
Symmetrical NFC receive interfaces use LC trap filters to remove base frequency harmonics, ensuring reliable communication over long coaxial cables.
