  • Patent number: 11736052
    Abstract: A fan control circuit with temperature compensation includes an on-off unit and a speed adjustment unit. When determining that a loading is greater than or equal to an adjustable start threshold according to a load signal, the on-off unit controls the fan entering a working mode. In the working mode and determining that the loading is less than a speed-adjusting threshold, the on-off unit maintains a speed value of the fan at a first fixed speed. When determining the loading is greater than or equal to the speed-adjusting threshold, the speed adjustment unit adjusts the speed value according to the loading. The speed adjustment unit generates a speed displacement according to a temperature signal to compensate the speed value.

    Abstract: One or more computer processors determine a runtime feature set for a first container, wherein the runtime feature set includes aggregated temporally collocated container behavior. The one or more computer processors cluster the first container with one or more peer containers or peer pods based on a shared container purpose, similar container behaviors, and similar container file structure. The one or more computer processors determine an additional runtime feature set for each peer container. The one or more computer processors calculate a variance between the first container and each peer container. The one or more computer processors, responsive to the calculated variance exceeding a variance threshold, identify the first container as anomalous.
