Abstract: A fluid flow turbine blade assembly for a turbine rotor includes a blade and a deflector extending spanwise along at least a portion of the blade. At least a portion of an upstream surface of the deflector, along at least a portion of a span of the deflector, has a concave shape in a chordwise direction such that at least a portion of a chord line between leading and trailing edges of the deflector is disposed outside a profile defined between the upstream surface and a downstream surface of the deflector. The deflector has a substantially uniform thickness or a chord-wise varying thickness between the upstream surface and the downstream surface. The deflector alters fluid flow over the blade so as to increase the blade's contribution to global torque generated by the assembly so that, with the deflector's torque contribution, the global torque of the assembly is greater than the global torque that would be generated by the blade alone without the benefit of the deflector.

An input receives an input signal which has a DC component. A first impedance element receives the input signal and blocks the DC component while a second impedance element connects between the output of the first impedance matching element and a ground node. The second impedance element and the first impedance element form a voltage divider network. The first and second impedance element are integrated elements. The amplifier receives the input signal after the DC component is blocked. The first impedance element and the second impedance element may comprise a resistor in series with a capacitor. In a differential pair configuration, an impedance matching element interconnects between a first path and a second path to impedance match the amplifier to a data source.

Abstract: A flexible coupling for a drive train, the coupling having a drive yoke, a driven yoke, and a connector for transferring rotational torque between the yokes. The drive and driven yokes are manually inserted into slots in the connector. The drive yoke connects to a drive shaft and the driven yoke connects to a driven shaft. Rotating the drive shaft rotates the drive yoke against the connector causing it to rotate; which in turn transfers torque to and rotates the driven yoke. Surfaces on the yokes and connector that contact one another during rotation define contact surfaces. Portions of the yokes and/or connector having the contact surfaces are obliquely profiled so that contact surfaces on the yokes are complementary to corresponding contact surfaces on the connector, which increases the areas of force transfer between the yokes and connectors.
