Magnetic Field Offset Compensation TRIZ Cases
- Magnetometer-Based Structural Damage Detection With Fewer False Alarms
Magnetic field displacement monitoring helps detect hidden structural damage and distinguish damaging impacts from false collision alarms.
- Integrated Hall Sensor Coil Layout for Uniform On-Chip Calibration
A 3D integrated coil encloses the Hall plate to create a nearly homogeneous field for on-chip test and calibration while reducing external calibration needs.
- Magnetic Sensor Calibration for Steel Sheet Inspection Accuracy
A two-stage calibration scheme aligns multiple magnetic sensors during steel sheet inspection without stopping production, improving measurement accuracy.
- Curved Protruding Magnetic Sensor Structure to Prevent Cracking
Curved protruding surfaces smooth the transition to inclined MR elements, suppressing cracks and improving magnetic sensor reliability.
- Electromagnetic Sensor Assembly for Non-Interfering Carrier Position Sensing
Opposed flux sensing detects carrier position accurately while avoiding magnetic interference with levitation and semiconductor processing.
- Magnetic Sensor Sensitivity Averaging for Stable Field Measurement
Sensitivity is calculated from an unweighted average of virtual points inside the housing, reducing complexity while preserving magnetic measurement accuracy.
- Magnetostrictive MR Sensor Biasing on Inclined Surfaces
Compressive stress and exchange-coupled magnetic layers boost bias field strength on inclined MR elements for more accurate perpendicular field detection.
- Susceptibility Probe Coil Taring for Accurate Surgical Marker Detection
A gradiometer coil layout and baseline voltage taring field offset residual sense-coil voltages for more accurate surgical marker localization.
- Complementary Coil Hall Sensor Layout for Process-Variation Calibration
Multiple complementary coils create matched reference fields that offset process variation and improve Hall sensor calibration accuracy.
- Magnetism Sensor Wiring Layout for Interference-Balanced Detection
Opposing front-surface wiring fields balance current flow and cut magnetic interference around the sensing element for cleaner detection.
- Hybrid Hall-MR Magnetometer Self-Calibration for Wide Dynamic Range
A Hall sensor calibrates MR bias error so the hybrid magnetometer keeps low-noise sensitivity across low fields and large DC fields.
- Magnetic Sensor Shield Structure to Prevent Insulating Layer Cracks
A side-covering organic or glass surrounding layer lets a thicker magnetic layer be formed in one step while reducing insulating layer cracks.
- Integrated Magnetic Sensor Chip for Weak Current Detection
An integrated sensor chip with a small magnetic gap concentrates leakage flux, enabling high-sensitivity detection of weak coil current.
