  • Patent number: 10614702
    Abstract: A method of tuning alarm parameters for condition monitoring of processing equipment in an industrial processing facility (IPF). For a selected process variable a first histogram is displayed from stored historical process data. An initial process alarm threshold is overlayed on the first histogram, and ON-time delay alarms are computed using an initial zero ON-time delay that would have occurred. A second histogram displays a distribution of alarms run length from alarm event data with the zero ON-time delay. Alarm tuning adjusts the initial process alarm threshold and/or the initial time delay, and an alarm performance is then evaluated from viewing the first and second histogram or viewing a hybrid display providing a time series plot including alarm event and process data, and the adjusting is repeated until the evaluating is deemed satisfactory. The new alarm tuning values are implemented to a control system of the IPF.

  • Patent number: 10523712
    Abstract: A stochastic estimation approach can be used to provide percentile determinations for data, such as may be received on one or more data streams. A stochastic approach can analyze each received request on a data stream and update the percentile values accordingly, providing near real time adjustment of the percentile values. One or more scaling factors or adjustment boundaries can be applied such that the estimations do not fluctuate excessively in response to individual requests. The near real time updates enable actions to be taken on the data stream, such as to generate alarms or initiate request throttling. The stochastic approach is very light weight, requiring minimal resources and having minimal latency.

  • Patent number: 10496731
    Abstract: A method, system, and processor-readable storage medium are directed towards calculating approximate order statistics on a collection of real numbers. In one embodiment, the collection of real numbers is processed to create a digest comprising hierarchy of buckets. Each bucket is assigned a real number N having P digits of precision and ordinality O. The hierarchy is defined by grouping buckets into levels, where each level contains all buckets of a given ordinality. Each individual bucket in the hierarchy defines a range of numbers—all numbers that, after being truncated to that bucket's P digits of precision, are equal to that bucket's N. Each bucket additionally maintains a count of how many numbers have fallen within that bucket's range. Approximate order statistics may then be calculated by traversing the hierarchy and performing an operation on some or all of the ranges and counts associated with each bucket.

  • Patent number: 9426592
    Abstract: Methods and systems for detecting the presence and frequency of clipping in an audio signal are provided. A clipping detection algorithm detects the presence of hard and soft clipping using histograms with intervals of samples, rather than attempting to identify the clipping value. Therefore, it is not essential to the algorithm that there be a large number of bins. Furthermore, the bins may be non-uniformly distributed since the number of samples belonging to lower amplitudes is of little importance. The detection algorithm is also configured to determine the severity and/or perceptual effect of any clipping found to be present in the signal by calculating the ratio of clipped samples to non-clipped samples. Temporal information on the occurrence of clipping in the signal is also used to evaluate perceptual effect.

  • Patent number: 8935127
    Abstract: A method for recording pulse signals which allows the reconstruction of a time reference. The time of every pulse signal event can be determined by counting sampling result bits preceding the respective sampling result bit using the known sampling frequency. For this purpose, every period of the sampling frequency is associated with a bit representing the respective sampling result and the sampling result bits are stored one by one and per channel in data blocks. The sampling frequency is preferably higher than a pixel clock, a sampling result bit associated with a flank of the pixel clock being marked. The pixel clock can thus be synchronized with the individual events exactly per sampling period. The invention further relates to the field of fluorescence correlation spectroscopy using confocal microscopes or laser scanning microscopes.

  • Patent number: 8868346
    Abstract: Systems, methods, and devices are provided to determine an accurate neutron-gamma density (NGD) measurement for a broad range of formations, including low-hydrogen-index or low-porosity formations and formations with heavy elements. For example, such an NGD measurement may be obtained by emitting neutrons into a formation such that some of the neutrons inelastically scatter off elements of the formation and generate inelastic gamma rays. The neutrons and inelastic gamma rays that return to the downhole tool may be detected. Some characteristics of certain formations are believed to affect the fast neutron transport of the formations. Thus, if a formation has one or more of such characteristics, a correction may be applied to the count rate of neutrons, the count rate of inelastic gamma rays, or the neutron transport correction function, upon which the neutron-gamma density (NGD) may be determined.

  • Patent number: 8803716
    Abstract: A chip with a built-in self-test (BIST) component capable of testing the linearity of an ADC is described herein. The BIST component uses hardware registers to facilitate a sliding histogram technique to save space on the chip. A subset of detected digital codes are analyzed, and DNL and INL calculations are performed by a controller to determine whether any of the digital codes in the subset exceed maximum or minimum DNL and INL thresholds. New digital codes being detected by the ADC are added to the subset as lower-value digital codes are pushed out of the subset, maintaining the same number of digital codes being analyzed as the subset moves from lower codes detected during lower voltages to higher codes detected at higher voltages. A synchronizer and pointer ensure that the subset moves through the digital codes at the same rate as the analog input ramp source.

  • Publication number: 20140207414
    Abstract: A real-time spectrum analyzer for measuring time domain data sampled from an input signal includes a processing unit and a density histogram memory unit. The processing unit includes an FFT engine, a frequency mask detector and a frequency mask gate. The FFT engine performs FFTs on the sampled time domain data to provide FFT spectra, each FFT spectrum including multiple FFT points. The frequency mask detector determines whether each FFT point in each spectrum meets a trigger condition, and generates gate control signals corresponding to the FFT spectra based on the determinations. The frequency mask gate receives the FFT spectra and the gate control signals, and outputs only select FFT spectra that contain at least one FFT point that meets the trigger condition in response to the corresponding gate control signal. The density histogram memory unit stores the select FFT spectra for generating in a density histogram.

  • Patent number: 8786624
    Abstract: Method and apparatus for improved processing for multi-channel signals. In an exemplary embodiment, an anomaly metric is computed for a multi-channel signal over a time window. The magnitude of the anomaly metric may be used to determine whether an anomaly is present in the multi-channel signal over the time window. In an exemplary embodiment, the anomaly metric may be a condition number associated with the singular values of the multi-channel signal over the time window, as further adjusted by the number of channels to produce a data condition number. Applications of the anomaly metric computation include the scrubbing of signal archives for epileptic seizure detection/prediction/counter-prediction algorithm training, pre-processing of multi-channel signals for real-time monitoring of bio-systems, and boot-up and/or adaptive self-checking of such systems during normal operation.
