  • Patent number: 9921937
    Abstract: Dimensionality reduction, such as principal component analysis, may be used at least in part to generate a model of time series observations of a computer application. The model may be applied to current and predicted observations. Outliers may be identified from current or predicted observations by analyzing those observations against the model, and statistically relevant outliers may generate alerts or corrective or other action to be taken. The outliers may be analyzed by searching for similar outliers that may have been previously observed, and predicting any future events based on similar observations of the past.

A display module receives the model output signal and visually displays the calculated wind flow and its effect on a plume if present in near real-time. The final system output is provided to authorized end users in near real-time.

  • Patent number: 9891088
    Abstract: Technologies are described herein for compensating for inaccuracies in flow measurement in real-time during accumulation of usage. A pulse count indicating an amount of flow in a meter over a measurement period is read. An average flow rate through the meter for the measurement period is determined and a correction factor is looked up from a table based on the average flow rate. A total usage accumulator for the meter is then updated with the amount of flow over the measurement period based on the pulse count and the correction factor.
