Abstract: 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.

Abstract: A method for analyzing vibration including: acquiring a vibration signal; isolating a vibration signal event in the acquired signal; determining a frequency of a damped sinusoid of the vibration signal event, wherein the damped sinusoid characterizes the vibration signal event, and using the characteristic damped sinusoid to identify an occurrence of the vibration signal event in another vibration signal.

Abstract: Methods, systems, and computer program products are provided for implementing condition monitoring activities. Systems include a processor in communication with a machine being monitored. The processor receives signals output by the machine via a signal conversion element associated with the machine. Systems also include a display device in communication with the processor for providing signatures of the signals received from the signal conversion element. Systems further include a means for identifying, isolating, and capturing a signature from the signatures presented on the display device. The systems also include a means for digitizing and recording the signature as an event kernel, normalizing the event kernel by performing a mean removal, and normalizing the energy to unity on results of the mean removal. Systems further include a storage device for storing normalized event kernels.

Abstract: A system, method, and article of manufacture for determining frequency values associated with forces applied to a device are provided. The method includes determining a first plurality of spectral amplitude values associated with a first forcing waveform applied to the device. The method further includes determining a second plurality of spectral amplitude values associated with a second forcing waveform applied to the device. The method further includes determining a maximum spectral amplitude value based on the first and second plurality of spectral amplitude values. The method further includes determining a threshold amplitude value based on the maximum spectral amplitude value and an acceptance value. The method further includes determining a first plurality of desired frequency values by selecting frequency values associated with a subset of the first plurality of spectral amplitude values that are greater than or equal to the threshold amplitude value.

Abstract: A method for calling and executing a program is disclosed. A command having zero or sequentially independent parameters values is received. The command corresponds to a program with a number of recognized parameters equal to or greater than the number of parameter values in the command. The parameter values are parsed based at least in part on demarcations in the command. The parameter values are associated with the corresponding parameters recognized by the program. Any parameter which did not have corresponding parameter values are set to default values. The program is executed to perform one or more tasks using the parameter values and the default values.
