Publication number: 20240104243Abstract: Multi-layer ensembles of neural subnetworks are disclosed. Implementations can classify inputs indicating various anomalous sensed conditions into probabilistic anomalies using an anomaly subnetwork. Determined probabilistic anomalies are classified into remedial application triggers invoked to recommend or take actions to remediate, and/or report the anomaly. Implementations can select a report type to submit, or a report recipient, based upon the situation state, e.g.Type: ApplicationFiled: November 27, 2023Publication date: March 28, 2024Applicant: LEDGERDOMAIN INC.Inventors: Victor Bovee DODS, Benjamin James TAYLOR, William JACK, Leonid ALEKSEYEV

Patent number: 11215321Abstract: A lubricant filter housing comprises a top plate defining a first opening. A base plate is positioned opposite the top plate. The lubricant filter housing further comprises at least one sidewall which cooperatively with the top plate and the base plate defines an internal volume. A plurality of plates are axially positioned in the internal volume between the top plate and the base plate. Each plate defines a plate opening axially aligned with the first opening which cooperatively with the first opening and a portion of the base plate, defines an internal cavity for housing a filter element. The plates define a first set of fluid channels structured to deliver a lubricant to the internal cavity, and a second set of fluid channels structured to provide a coolant around the first set of fluid channels.Type: GrantFiled: October 26, 2018Date of Patent: January 4, 2022Assignee: Cummins Inc.Inventors: James A. Dods, Paul Andrew Leggott
