Active Shielding TRIZ Cases
- Coil Active Shield Structure for EM Side-Channel Masking
Coil-shaped metal lines create electromagnetic noise that masks logic leakage while preserving tamper detection without extra area or power.
- Spiral Active Shield Structure for EM Side-Channel Protection
Coiled shield spirals and interleaved windings generate masking EM noise while trip-wires protect sensitive circuitry from probing.
- Battery Switching Circuit Layout for Low-Radiation Power Supply
Side-by-side high-voltage lines and circular battery switching units shrink loop area to cut radiation and protect nearby electronics.
- Steering Wheel Hand Sensor Shielding for Signal Crosstalk Isolation
A shield or heater mat blocks frame interference and isolates return wires, improving steering wheel hand sensor accuracy.
- Steering Wheel Hand Sensor Shielding With Dual-Use Heater Mat
A dual-use heater mat or separate shield mat blocks frame interference and isolates sensing zones to improve steering wheel hand detection.
- Active Magnetic Shielding With Feedback for MEG Field Distortion
Feedback-controlled coil arrays and field sensors cancel external magnetic interference while limiting distortion during subject movement in MEG.
- Air-Filled Waveguide Channel in Multilayer PCB
A barrier layer prevents adhesive intrusion into the air-filled waveguide channel, resolving manufacturing trade-offs while maintaining signal integrity.
- Door System PWM Frequency Adjustment for EMI Reduction
Dynamic pulse width modulation adjustment prevents electromagnetic interference between automatic door drives and security systems.
- Active Shield Keypad for Secure Input
An active-shield layer integrates electromagnetic shielding with keypad sensing to detect key presses.
