Current Measurements Only TRIZ Cases
- Current Sensor Gap Alignment for Magnetic Shielding Accuracy
A current sensor positions a magnetic shield gap at the same height as the sensor substrate to align the gap magnetic field perpendicularly.
- Coreless Current Sensor with Orthogonal Magnetic Detection
Orthogonal magnetic detection units reduce mutual interference from adjacent conductors, enabling accurate current measurement without a magnetic core.
- Amperometric Transformer Current Sensing Circuit for DC Component Detection
A current sensing circuit uses an offset capacitor to store voltage offsets during zero current periods.
- Current Sensor Impedance Matching for Signal Integrity
Constant impedance filtering resolves 4 ohm mismatch with 50 ohm cables, suppressing resonance and maintaining detection precision.
- Variable Hall Sensor Current Control for Precision Measurement
A current measurement apparatus adjusts hall element driving current dynamically to maintain high precision across varying magnitudes.
- Wideband Contactless Magnetoresistive Rogowski Current Sensing
Aggregates magnetoresistive and Rogowski coil signals to enable isolated high-frequency measurement up to 10 MHz, eliminating integrator circuits.
- Multi-Substrate Current Sensor for Tight Conductor Pitch
Distributing current measurement coils across stacked substrates enables tight conductor pitch while maintaining sensitivity through electromagnetic induction.
- Current Sensor Windings with Orthogonal Sensitivities
Stacked windings with orthogonal sensitivities cancel interference from adjacent conductors, enhancing measurement precision.
- Magneto-resistive Sensor Stress-Induced Anisotropy Stabilization
A magneto-resistive element uses orthogonal bias fields and controlled magnetostriction to stabilize resistance.
- Tubular Electrical Sensor Assembly for Transformer Field Detection
Segmented shielding layers isolate the detection element from external interference to ensure accurate transformer measurements.
