  • Patent number: 11841027
    Abstract: A demand-based load balancing function may be provided by one or more drive controllers that takes advantage of the affinity laws to linearize the control of the variable of interest (e.g., flow, pressure, etc.). Each drive controller may be set up by the user simply inputting a few values into the drive controller. Based on the inputs, the drive controllers may interpolate control points using an assumed linear relationship between the variable to be controlled (e.g., pressure) and the current driven to the pump. Feedback data from the system may be used to continually update the drive controllers so as to potentially allow them to better balance power usage to each pump.

  • Publication number: 20230376962
    Abstract: The system and methodology of the present invention employs available data obtained in connection with previous transactions to create one or more databases comprising feature sets which are used in transaction decision making solutions. The available data from previous transactions which is used in creating feature sets may include all available production data or the data may be stratified across specific industries and/or across specific decision support customers to optimize the expected decision making results. A feature engine is provided which uses a combination of data, time and combinational aggregate functions to feature engineer one or more feature sets used for one or more purposes, such purposes to include identity verification, fraud assessment, document verification as well as other assessments related to selectively permit or not permit transactions to proceed.
