  • Patent number: 10872031
    Abstract: An analysis system receives a time series. The data values of the time series correspond to a metric describing a characteristic of the computing system that changes over time. The analysis system stores a statistic value that represents the stationarity of the time series. In response to receiving a most recent value, the analysis system assigns the most recent value as the leading value in a window before retrieving the trailing value of the window. The analysis system updates the statistic value to add an influence of the most recent value and remove an influence of the trailing value. If the statistic value is less than a threshold, the analysis system determines that the time series is stationary. In response to determining the time series is stationary, the analysis system assigns an alert to the metric. The analysis system detects an anomaly in the metric based on the assigned alert.

  • Patent number: 9349422
    Abstract: The disclosed embodiments related to a clocked memory system which performs a calibration operation at a full-rate frequency to determine a full-rate calibration state that specifies a delay between a clock signal and a corresponding data signal in the clocked memory system. Next, the clocked memory system uses the full-rate calibration state to calculate a sub-rate calibration state, which is associated with a sub-rate frequency (e.g., ½, ¼ or ? of the full-rate frequency). The system then uses this sub-rate calibration state when the clocked memory system is operating at the sub-rate frequency. This calculation of the sub-rate state calibration states eliminates the need to perform an additional time-consuming calibration operation for each sub-rate.

  • Publication number: 20150142361
    Abstract: Systems and methods are provided to perform dead time correction. An observed ion count rate is obtained using a non-paralyzable detection system of a mass spectrometer. The detection system includes an ion detector, a comparator/discriminator, a mono-stable circuit and a counter. The non-paralyzable detection system exhibits dead time extension at high count rates. The extension of the dead time occurs because the mono-stable circuit requires a rising edge to trigger and can only be triggered again after the output pulse from the comparator/discriminator has gone low. This allows a second comparator/discriminator pulse arriving just before the end of the dead time started by a first comparator/discriminator pulse to extend the dead time to the trailing edge of the second comparator/discriminator pulse. A true ion count rate is calculated by performing dead time correction of the observed ion count rate.

  • Publication number: 20150127284
    Abstract: Techniques for sensor data time alignment are described. According to one or more embodiments, sensor data from different sensor systems is time-aligned to a reference time base. For instance, reference time values may be propagated to sensor systems to enable the sensor systems to mark sensor data based on the reference time values. Sensor data from a sensor system may be time-aligned by applying an alignment policy to the sensor data. An alignment policy, for example, accounts for a difference between a time base of a sensor system and a reference time base. Thus, sensor data from different sensor systems may be aligned to common time values in a variety of different ways.

    Abstract: In an analyzing system including a commanding unit for sending a command and an executing unit for executing a processing upon receiving the command, a processing instruction may not be executed at the right time due to a heavy traffic of information and other factors. In order to solve this problem, in a preparative separation system 1 according to the present invention, a PC 20 provides the execution time for starting/finishing the fractionation processing to a controller 18. Therefore, even in the case where the time of the PC 20 and that of the controller 18 are not synchronized, the controller 18 can accurately set the execution time for starting/finishing the fractionation in a preparative separation unit 16. A piping 17 may be placed so that the traveling time of sample components is sufficiently larger than the delay time of signals due to the signal transfer lag and other reasons. This can absorb the delay time, allowing the units to cooperate with each other at a correct timing.

  • Publication number: 20140129169
    Abstract: Before executing a search for optimal correspondence relationship with a coarse-to-fine DP (dynamic programming) algorithm using time information of peaks appearing in a chromatogram as input data, a simplified linear correction is executed based on detection of start point and end point of the section in which the peaks are present. It is sufficient to correct only nonlinear time deviations in coarse-to-fine DP, and the space to be searched is thus narrowed down. In addition, in coarse stage DP, the number of pieces of data to be processed is reduced by selecting peaks based on peak intensity. Between coarse stage DP and fine stage DP, local inappropriate matching is eliminated by performing filtering processing in accordance with trend of time deviations over the entire chromatogram. The space to be searched in fine stage DP becomes narrow, which reduces the number of candidates to be searched and shortens the calculation time.
