Converting Sensor Output Electrically/Magnetically TRIZ Cases
- Resolver Phase-Shift Monitoring for Early Insulation Fault Detection
Phase-shift tracking between rotor excitation current and stator voltages detects resolver insulation deterioration early, preserving position accuracy.
- Solenoid Position Sensing via Coil Current Fluctuations
Coil current fluctuations reveal armature position without a dedicated sensor, cutting solenoid cost, calibration effort, and failure points.
- Magnetic Encoder Spiral Track for Low Pole Pair Quadrature Sensing
Archimedean spiral pole transitions let magnetic encoders keep quadrature signal quality with few pole pairs and compact sensor integration.
- Orientation-Sensing Remote Load Control for Flexible Mounting
An orientation sensing circuit lets a wire-free wall control adapt user inputs to any mounting direction for intuitive electrical load control.
- Capacitive Touch Lighting Control With Gesture Feedback
Capacitive touch gestures replace simple switches to control lighting power and color while visual feedback improves operation of complex loads.
- Multi-Phase Signal Processing for Temperature-Stable Angle Sensing
Normalized positive-sequence vector processing improves motor angle estimation accuracy and reduces temperature-driven sensor errors.
- Rearview Mirror Position Sensing With Asymmetrical Magnetic Field
An asymmetrical magnet and sensor layout improves 3-axis rearview mirror position sensing while accounting for background magnetic disturbances.
- Flux Collector Structure for Stable Magnetic Torque Sensing
Reinforced bead-stiffened flux collectors improve handling and cut part variation while preserving interference-resistant magnetic torque sensing.
- Brake Pedal Displacement Sensing in a Compact Hydraulic Block
A magnet-and-shaft sensor built into the hydraulic block measures brake pedal stroke accurately while reducing installation adjustment and assembly size.
