摘要： A DC-DC power converter having a power source, a load, and a transmission line terminated at one end. A first switch is electrically connected between the power source and a second end of the transmission line and movable between an open and a closed position. A second switch is electrically connected between the second end of the transmission line and the load and is movable between an open and a closed position. A switch control circuit switches the first and second switches between their respective open and closed positions. A pulse forming network forms the transmission line to store the charge in the transmission line.

摘要： A MEMS switch and method of fabrication comprises a RF transmission line; a RF beam structure comprising a RF conductor; a cantilevered piezoelectric actuator coupled to the RF beam structure; a plurality of air bridges connected to the cantilevered piezoelectric actuator; and a plurality of contact dimples on the pair on the RF beam structure. The RF transmission line comprises a pair of co-planar waveguide ground planes flanking the RF conductor; and a plurality of ground straps, wherein the RF transmission line is operable to provide a path along which RF signals propagate. The cantilevered piezoelectric actuator comprises a dielectric layer connected to the RF beam structure; a bottom electrode connected to the dielectric layer; a top electrode; and a piezoelectric layer in between the top and bottom electrodes, wherein the top electrode is offset from an edge of the piezoelectric layer and the bottom electrode.

摘要： Engine fuel injector control circuitry comprising a pulse generator that duces long duration pulses. NOR gate circuitry is actuated by each pulse to operate a ramp generator. The ramp generator output changes at a rate determined by current flow generated by an engine speed sensor. Ramp generator output is applied to an input terminal of a comparator to produce rapid switching of the comparator output for starting the injection of fuel into an engine cylinder. Injection is terminated by the trailing end of the long duration pulse.
