    • 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.
    • 一对具有彼此重合的纵轴的翼型叶片。 每个叶片在和弦平面上的中心弯曲。 每个叶片具有放置在最外侧最后缘的翼型末端叶片。 叶片的根端固定在扭转轴的相对端。 叶片和弦彼此偏移,这限定了叶片桨距角。 扭转轴通过驱动轴垂直地轴向旋转,而叶片的旋转可以通过扭转轴传递到驱动轴,并使驱动轴转动,从而无需轮毂。 叶片适于与扭转轴一起枢转。 叶片位于基本上相同的平面中,并且适于在与驱动轴的纵向轴线正交的平面中旋转。 每个叶片具有设置在前缘上的翼型流体闸阀。

    • 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.
