Resistance/Reactance/Impedence TRIZ Cases
- Distribution Line Parameter Estimation Using iPINN Voltage Dynamics
Lossy Distflow equations and an inverse PINN estimate line resistance, reactance, voltages, and flows with lower computation.
- RF Connector Coupling Detection Using Capacitive Monitoring
Capacitance sensing near the RF connector detects abnormal cable coupling without disassembly, cutting defect analysis time and cost.
- Power Distribution Monitoring Circuit for In-Rush Current Protection
Impedance-based load detection temporarily inhibits short-circuit protection during startup surges, preventing false trips and reducing component cost.
- Battery Separator Dielectric Sensing for Internal Temperature Monitoring
A temperature-sensitive separator dielectric enables direct internal battery temperature monitoring, improving thermal runaway detection speed.
- Resistance-Bridge Directional Coupler for Wideband Chip Integration
A resistor-bridge directional coupler separates incident and reflected waves across a wide band while shrinking chip area for lower-cost vector network analyzers.
- Connector-Integrated Resistive Coupler for Wideband Signal Separation
Ports and resistors built into the connector simplify wideband coupler integration while preserving transmit and receive signal separation.
- Battery Conductive Material Evaluation Using Simulated Particle Coatings
Simulated insulative particles and a test coating isolate substrate and particle-gap effects, improving conductive material evaluation in rechargeable batteries.
- Battery Cell Temperature Estimation via EIS Without Thermistors
Core battery temperature is inferred from EIS voltage and current measurements, avoiding thermistors, extra wiring, and casing thermal lag.
- TSV Validation Structure Using a Smaller Reference Via
A smaller reference TSV is etched and tested first to verify SiC via formation, reducing over-etch and under-etch risk in ICs.
- Battery Impedance Measurement Using Multi-Step Staircase Waves
A multi-step staircase input captures more low-frequency impedance points in one measurement, improving battery condition diagnosis accuracy.
