Optical image stabilization system occupy an important place in infrared imaging products. Piezoelectric actuators have great advantages such as high-response and high-precision. A 2D stage using linear piezoelectric actuators is designed to achieve image stabilization. The piezoelectric linear actuator contains a shrinkage amplification mechanism and a stretching amplification mechanism, which can...
The use of self-healing glass as hermetic seals is a recent advancement in sealing technology development for the planar solid oxide fuel cells (SOFCs). Because of its capability to restore mechanical properties at elevated temperatures, the self-healing glass seal is expected to provide high reliability in maintaining the long-term structural integrity and functionality of SOFCs. To accommodate the...
The modeling and simulation of via's effect on the data transferring or high frequency signal path and device performance have been one of the major concerns in the designing and testing of multilayered electric interconnects in applications like highly integrated system-in-package (SIP) and high-speed circuitry design. The authors of this paper explore the 3D full-wave modeling of through Si vias...
A simulation model based on finite-element method is presented to analyze the soil ionization phenomenon around the grounding system under the impulse current. In this method, The non-linear characteristic of soil under an accidental short circuit or a stroke of lightning is taken into account by setting the resistivity of soil element varying with the electric field intensity of every element; open...
A power transformer operating in electric network is supplied by voltage source. When analyzing short-circuit currents and forces of the three-phase power transformer applied to windings during its short-circuit procedure, the field-circuit coupled method is needed.
