  • Data-driven features via signal clustering
    Patent number: 11055319
    Abstract: A method is described of identifying time-series signals that contain information useful for predicting impending event messages relating to one or more of safety, maintenance, and system operation information before they occur. The method includes loading a plurality of time-series signals with assigned signal name and associated time-series data into a machine-readable storage medium and grouping the plurality of time-series signals based on textual similarity of the corresponding signal names into a signal cluster.
    Type: Grant
    Filed: March 29, 2018
    Date of Patent: July 6, 2021
    Assignee: Hamilton Sundstrand Corporation
    Inventors: Joseph J. Ensberg, Chetan Prabhu, Marlee Ann Stevenson, Kamron Saniee
  • Heat exchanger blockage detection
    Patent number: 10690366
    Abstract: A system and method includes at least one heat exchanger, a ram fan, and a controller. The ram fan is driven by a motor. A motor control circuit is configured to provide power to the motor to drive the ram fan. The ram fan is configured to provide a ram flow through the at least one heat exchanger from a ram air inlet. The controller is configured to determine a blockage level of the at least one heat exchanger based on the power to the motor, a speed of the ram fan, and a temperature of the ram flow at the ram fan.
