Arm With Actuators TRIZ Cases
- Microactuator Hysteresis Compensation via Inverse Digital Filter
A digital filter based on an inverse Coleman-Hodgdon model linearizes microactuator response in disc drives.
- Piezoelectric Element Crack Detection via Transfer Function
A piezoelectric element pair uses voltage-induced deformation to generate a transfer function for crack detection.
- Multi-layer Piezoelectric Actuator Electrode Asymmetry for Torsion Mode Suppression
Asymmetric electrode lengths in multi-layer piezoelectric actuators suppress torsion mode excitation, eliminating notch filters to improve servo bandwidth.
- Magnetic Head Suspension Insulative Adhesive Barrier
Surrounding insulative adhesive encapsulates lower conductive adhesive agents on a magnetic head suspension flexure to maintain electrical connections.
