  • Patent number: 11374876
    Abstract: This disclosure relates to deployment of additional workload in the NFV-MANO to efficiently utilize resources during a lean workload period of Virtual Network Functions (VNFs) associated with an intelligent cloud platform. The method comprises measuring, over a time period, a current resource utilization level of one or more rendered VNFs. Thereafter, forecasting future resource utilization for the time period based on predictive analysis criteria and the current resource utilization level of the one or more VNFs. The method further comprises a machine learning based inference for determining whether the forecast future resource utilization for said time period is less than a determined optimal resource utilization threshold value of the one or more VNFs. Thereafter, resources of the one or more VNFs to one or more additional workloads are allocated based on the determination of the future resource utilization.

    Abstract: A harvester includes a chassis, a separation frame movably supported by the chassis and upon which crop material is deposited, a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame, a control system, a sensor programmed to produce a signal indicative of a tilt of the chassis relative to a gravitational direction, and programmed to provide the signal to the control system, and an adjustable link operably coupled between the separation frame and the chassis to adjust a pivot point of the separation frame. The control system is programmed to determine a change in tilt of the chassis based on the signal from the sensor. The controller is programmed to adjust the adjustable link to modify the pivot point of the separation frame in response to the change in tilt of the chassis.
