Using Electrical Means TRIZ Cases
- Portable Device Lid-Angle Sensing With Inertial Data Fusion
Environmental vibration can distort portable-device opening angles; weighted accelerometer and gyroscope fusion enables adaptive, reliable measurement.
- Inductive Sensor Receiver Coil Layout for Compact Series Connection
Internal series connections between offset, multilayer receiver loops save radial space and improve signal quality in rotary inductive sensing.
- Dynamic Angle Sensor Calibration for Bicycle Rear Suspension
A dynamic routine calibrates an angle sensor in varied mounts to track rear suspension extension, compression, and wheel position.
- Pivotable Magnet Orientation Sensor Using Magnetic Field Gradients
Magnetic field gradients let paired sensors calculate two orientation angles for a pivotable magnet, reducing sensitivity to temperature and disturbance fields.
- Mower Steering Sensor Assembly With Rotary Displacement Amplifier
A rotary displacement amplifier magnifies small lap bar movements so a lower-cost rotary sensor can precisely control the mower's electric motor.
- Inductive Sensor Coupling Overlap for Error and Signal Balance
Optimizing conductive coupling overlap balances measurement error and signal amplitude for compact inductive movement sensing with larger air gaps.
- Inductive Movement Sensor Overlap Tuning for Signal Accuracy
Optimizing the conductive coupling segment overlap reduces measurement error and raises signal amplitude, supporting larger air gaps and simpler amplifiers.
- Polarized Magnetic Charge Mapping for 3D Wall Thinning Detection
Magnetic field measurements are converted into polarized charge distributions to estimate 3D wall thinning despite sensor noise.
- Inductive Angular Position Sensor With Non-Resonant Excitation
A non-resonant driver and difference encoder enable fast, low-power angle tracking for battery-operated inductive sensors.
- Pipeline Defect Inversion Through Heterogeneous Signal Normalization
Heterogeneous pipeline signals are normalized, denoised, and transformed before models estimate defect length, width, and depth.
- Foldable Electronic Housing Angle Detection with Dual Sensors
A reference-angle sensor and a change-sensing sensor help correct noise and stress-relaxation errors in foldable housing angle calculations.
