Magnetic Measurements TRIZ Cases
- Sensor Package Diagnostic Interface Using Supply Current Modulation
Diagnostic data is encoded in supply current so a three-terminal sensor package can report faults without extra pins, reducing cost and complexity.
- Coil Orientation Patterns for MRI Magnet Field Homogeneity
Rotating MRI magnet coils to optimized orientations reduces spatial field inhomogeneity and shimming effort while improving image quality.
- Hall Sensor Fault Detection for Brushless Motor Commutation
Predicting the next Hall sensor state from prior states and shaft direction helps detect motor sensor faults early and reduce maintenance.
- Multipart Pole Piece Shimming for Halbach Magnet Field Homogeneity
Adjustable shim layers in a multipart pole piece improve Halbach magnet field homogeneity in compact NMR systems with limited space.
- Spin-Orbit Torque Wiring for Low-Current Magnetization Reversal
Pure spin current from spin-orbit torque wiring reverses magnetization with lower current density, reducing Joule heat and extending MRAM element life.
- Magnetic Tunnel Junction Seed Layer Structure for High TMR
Amorphous CoFeX and CoFeXTa seed layers preserve heat stability while improving pinned and free layer crystallinity for higher TMR and Hex.
- Polysilicon Diode ESD Layout for Stacked Die Interconnect Pads
Integrated polysilicon diodes in dielectric layers protect stacked-die interconnect pads from ESD without adding separate protection structures.
