  • Patent number: 10889967
    Abstract: A dual purpose valve assembly may comprise a conduit, a first valve, and a second valve. The first valve may comprise a vacuum breaker valve. The second valve may comprise a check valve. A drain system may comprise a supply tube, a drain tube, and a dual purpose valve disposed between the supply tube and the drain tube. The drain system may allow fluid to drain based on gravity alone, and the dual purpose valve assembly may operate based on gravity alone.

  • Publication number: 20200347787
    Abstract: A hybrid electric propulsion system includes a gas turbine engine having at least one compressor section and at least one turbine section operably coupled to a shaft. The hybrid electric propulsion system includes an electric motor configured to augment rotational power of the shaft of the gas turbine engine. A controller is operable to determine an estimate of hybrid electric propulsion system parameters based on a composite system model and sensor data, determine a model predictive control state and a prediction based on the hybrid electric propulsion system parameters and the composite system model, determine a model predictive control optimization for a plurality of hybrid electric system control effectors based on the model predictive control state and the prediction using a plurality of reduced-order partitions of the composite system model, and actuate the hybrid electric system control effectors based on the model predictive control optimization.

  • Publication number: 20200012445
    Abstract: Embodiments of the present disclosure provide methods and apparatus for path selection in a storage system. The storage system includes a plurality of storage devices, each storage device being connected to a plurality of different HBA ports of a server via a plurality of paths; the method comprises: monitoring a system-wide performance metric of the storage system to obtain dynamic performance statistics; detecting a performance-related event based on the dynamic performance statistics; and selecting, from the plurality of paths, an active path for a storage device of the plurality of storage devices based on the dynamic performance statistics and a result of the detecting. With the methods or apparatus according to the embodiments of the present disclosure, performance bottleneck can be avoided or timely eliminated, load balance can be achieved, and system resources can be utilized more effectively.

  • Patent number: 9574928
    Abstract: A liquid level sensing system includes a vessel and an electrode. The vessel includes a vessel wall separating a vessel interior from a vessel exterior. The electrode is mounted to an exterior side of the vessel wall spanning a distance corresponding to a desired-level-determining range. The vessel wall is a dielectric gap between the electrode and the vessel interior. The electrode is configured to collect a charge corresponding to a liquid level. A method for determining a liquid level in a vessel includes collecting a charge on an electrode, sensing the collected charge on the electrode with a capacitance sensor through an electrical line, and determining a liquid level in a vessel based on the collected charge sensed by the capacitance sensor.

  • Publication number: 20120111432
    Abstract: An aircraft potable water system (20) comprises outlet facilities (30) and a recirculation path (40) that supplies potable water thereto. The system (20) can operate in a high-usage condition whereat recirculation through path (40) is temporarily interrupted, thereby permitting supply water pressure to remain relatively high despite water being quickly tapped therefrom.
