    摘要： A method of monitoring the condition of a machine is provided. The method includes receiving an input complex signal from the machine wherein the input complex signal has a plurality of signal components. The plurality of signal components includes at least one signal component containing a pre-determined frequency of interest and at least one signal component containing noise. The method further includes processing the input complex signal and generating an output complex signal having a plurality of signal components The plurality of signal components includes at least one signal component containing a pre-determined frequency of interest and at least one signal component containing noise. Processing the input complex signal includes executing a fixed-step integration and processing the output complex signal to assess whether a fault exists.

    摘要： A power distribution system includes a plurality of node devices and a computer communicatively coupled to the node devices. The computer includes a memory area configured to store at least one operating parameter of each of the node devices, and a processor that is programmed to determine a desired operating limitation of the power distribution system to be optimized, calculate an effect on the operating limitation based on a modification of the operating parameter of at least one of the node devices, and transmit a command to the node device to cause the node device to modify the operating parameter.
