    摘要： The present invention relates to a method of electrodepositing metal onto a substrate, which comprises applying a pulsed periodic reverse current across the electrodes of a plating cell utilizing a peak reverse current density and peak forward current density; and varying the ratio of peak reverse current density to peak forward current density in periodic cycles to provide metal deposits of uniform thickness and appearance upon the substrate. The invention also relates to a process for improving the properties of an electrodeposit, particularly on substrates having uneven surfaces or apertures, by using programmed pulse periodic reverse current modulation. More particularly, it involves varying the anodic to cathodic current density ratio, in order to improve the surface uniformity appearance, grain structure and levelling of the deposit while maintaining high current density throwing power.

    摘要： The micro-electromechanical (MEMS) switch comprises a first double-sided cantilever MEMS actuator attached to a substrate and movable in two opposite directions, and a second cantilever MEMS actuator attached to the substrate. In use, the first MEMS actuator is moved in either directions to distribute the stress more uniformly, thereby reducing the mechanical creep and improving its reliability as well as its operation life.

    摘要： The electro-mechanical relay comprises a base having a transversal axis and a rocking member operatively connected over the base. The rocking member is pivotable, with reference to the transversal axis, between a first position and a second position. The relay also comprises a first contact provided on the base at a location facing the rocking member and being spaced-apart from the transversal axis, and a second contact having at least a portion provided on the rocking member and being in registry with the first contact. The first and second contacts are configured and disposed to be electrically engaged at the first position of the rocking member, and electrically disengaged from each other at the second position thereof.
