    Abstract: A capacitive sensor system including a sensing plate, an amplifier, and a switching circuit is described. The sensing plate is capacitively coupled to a body surface. A change in the electric potential on the body surface generates an electric field that induces change in the electric potential of the sensing plate. The sensing plate includes a sensing node positioned in the electric field for generating an input signal from the electric field. The sensing plate is not in contact with the body surface. The amplifier receives the input signal at the input port, amplifies the input signal and generates an output signal at the output port. The switching circuit is connected to the input port and a reference voltage. The switching circuit non-continuously closes a shunting path from the sensing node to the reference voltage to reset the voltage at the sensing node.

    Abstract: A gas turbine engine has a forward rotor, a row of fan blades radially extending from the rotor, and a core turbine engine located rearwardly of the fan blades and rotor and coupled to the rotor for rotatably driving the rotor. An outer annular nacelle surrounds the rotor, fan blades and core engine. An inner annular splitter fairing is disposed rearwardly of the fan blades, surrounds the core engine, and is spaced radially inwardly from the nacelle so as to define therebetween a bypass air flow duct located outwardly from the core engine and rearwardly of the fan blades for producing thrust upon rotation of the rotor and fan blades. A hybrid shape spinner nose is attached about the rotor and projects forwardly therefrom within the nacelle and forwardly of the fan blades. The hybrid shape spinner nose has a forward substantially conical section spaced forwardly of the fan blades, a rearward substantially conical section projecting forwardly of and merging rearwardly with the fan blades, and a transition connecting the forward and rearward sections such that the spinner nose is provided with a compound, substantially conical configuration in which the slope of the forward substantially conical section is greater than the slope of an imaginary conical surface connecting a front end of the spinner nose and a leading edge of the annular splitter fairing, whereas the slope of the rearward substantially conical section is less than the slope of such imaginary conical surface.
