Abstract: An apparatus for providing a synchronized timing signal is provided. The apparatus includes a touch-stimulus system that generates a tactile stimulus in response to a driver signal. The apparatus also includes a conversion system that receives a data signal that includes timing data, and which generates a timing signal that is synchronized with the timing data. A driver system is connected to the tactile stimulus system and the conversion system. The driver system receives the timing signal and generates the driver signal, such that the driver signal is synchronized with the timing data.

Abstract: An auxiliary stranded copper conductor carries the fault currents generated by a diode failure about the periphery of a brushless exciter diode wheel. The auxiliary conductor is constructed with a lower high-frequency impedance than the adjacent diode wheel, so that AC fault currents in particular are diverted to the auxiliary conductor. The auxiliary conductor carries the fault currents to equalize both AC and DC fault currents among the fuse-legs of the same phase. In a preferred embodiment, the auxiliary conductor is circular and is mounted between all of the diode fuse bases at one end of the diode wheel and the diode wheel itself.
