Rapid Change Measurement TRIZ Cases
- Capacitive Pressure Measuring Cell Monitoring for Membrane Damage
Thermal shocks can mimic membrane damage in capacitive pressure cells; lookup-table comparisons trigger compensation or fault signaling.
- SAW Sensor Engine Knock Detection via Strain Measurement
A surface acoustic wave sensor detects engine knock by measuring strain-induced resonant frequency changes.
- Knocking Detection via Multi-Band Vibration Filtering
A knocking determination device extracts vibrations across three identical frequency bands to identify engine knock signals.
- Multi-hole Probe Pressure Sensors with Optical Transduction
Remote optical transducers eliminate pneumatic lag in multi-hole probes, enabling accurate high-frequency pressure measurements.
- Amplifier Circuit for Piezo Sensor Parasitic Signal Neutralization
A measurement amplifier circuit generates a common mode voltage signal to neutralize parasitic charges across sensor terminals.
- Piezoceramic Material Composition for Knock Sensor Stability
Sn, Nb, Sb doped piezoceramic suppresses pyroelectric voltage to stabilize sensitivity across wide temperature ranges.
