    摘要: A pair of airfoil blades having a longitudinal axis coincident with one another. Each blade is bent at the center on the plane of the chord. Each blade has an airfoil tip blade placed at the outer most trailing edge. The blades are affixed by their root ends to opposite ends of a torsion shaft. The blade chords are offset from one another, which defines a blade pitch angle. The torsion shaft is journaled perpendicular through a driveshaft, whereas the rotation of the blades can transfer through the torsion shaft to the driveshaft and cause the driveshaft to turn, eliminating the need for a hub. The blades are adapted to pivot along with the torsion shaft. The blades lie in substantially the same plane, and are adapted for rotation in a plane orthogonal to the longitudinal axis of the driveshaft. Each blade has an airfoil shaped fluid gate valve disposed on the leading edge.

    摘要: An electrostatic discharge (ESD) protected circuit is coupled to a power supply voltage rail and includes a multiple independent gate field effect transistor (MIGFET), a pre-driver, and a hot gate bias circuit. The MIGFET has a source/drain path coupled between an output pad and the power supply voltage rail and has a first gate terminal and a second gate terminal. The pre-driver circuit has an output. The hot gate bias circuit is coupled to the first gate terminal of the MIGFET, and the output of the pre-driver circuit is coupled to the second gate terminal of the MIGFET. The hot gate bias circuit is configured to apply a bias voltage to the first gate terminal of the MIGFET during an ESD event that increases the breakdown voltage of the MIGFET so as to better withstand the ESD event.

    摘要: Circuitry on integrated circuits usually includes protection against electrostatic discharge (ESD) events. A second ESD current path may be provided in addition to a first ESD current path for shunting ESD current away from circuitry to be protected during an ESD event. In addition to the standard power and ground buses used to provide power and ground voltages to the protected circuitry, one or more extra power and/or ground buses and associated circuitry may be added for improved ESD protection.
