Electric Devices TRIZ Cases
- Resonant Slot Power Detection for Low-Complexity Real-Time Control
By estimating total input power from resonant-slot baseband power, this circuit avoids high-speed sampling and simplifies real-time control.
- Wire EDM Feeder Deterioration Detection Using Current and Discharge Signals
Monitoring machining current, discharge count, and resistance voltage reveals feeder deterioration early and helps prevent defective wire EDM workpieces.
- RF Power Detector Threshold Switching for Offset Drift Compensation
Switched threshold voltages and OSDAC calibration counter rectifier offset and temperature drift to keep RF power measurements accurate.
- Multi-Stage Hydrotreating for Low-Sulfur Heavy Marine Fuel Oil
Sequential catalyst beds cut sulfur and contaminants in heavy marine fuel oil while preserving ISO 8217 compatibility and bunkering use.
- Multi-Stage HMFO Hydrotreating for Low-Sulfur Marine Fuel
Multi-stage hydrotreating with catalyst beds and separation cuts sulfur and contaminants in heavy marine fuel while preserving ISO 8217 properties.
- RF Power Amplifier Detector Circuit for Temperature-Stable Power Sensing
Matched reference diodes and a parallel RC compensation path cancel offset drift and stabilize RF power detection across temperature.
- Differential RF Power Detection With Common-Mode Rejection
A capacitor-transistor detection path rejects common-mode signal error so differential RF power can be measured accurately.
- Logarithmic Power Detector With DC Offset Noise Compensation
Different DC offsets across staged detectors cut high-frequency noise errors and preserve log-linear power detection at low input levels.
- Switch State Detection with Adaptive Threshold Voltage Control
Adaptive threshold control and terminal voltage checking reduce false switch ON/OFF readings caused by aging and abnormal voltage levels.
- Logarithmic Mean-Square RF Power Detection Across Wide Dynamic Range
Multiple gain and attenuation detector stages are summed to measure complex RF signal power accurately across a wide dynamic range.
