摘要： A locomotive is disclosed. The locomotive includes a car body, including an operator cabin, a power source, and an operator health monitor within the operator cabin, the operator health monitor configured to monitor at least one health condition associated with the operator and configured to generate an operator health signal associated with the at least one condition. The locomotive includes an operator warning system within the operator cabin, configured to present the operator with an operator warning in response to an operator warning signal, and an electronic controller. The electronic controller may be configured to determine an operator fatigue score based on, at least, the operator health signal, determine if the operator fatigue score exceeds a warning threshold, and transmit the operator warning signal to the operator warning system if the operator fatigue score exceeds the warning threshold.

摘要： A condensation system for a reservoir, which stores fuel cryogenically, is disclosed. A portion of the fuel exists as a boil-off gas with a first vapor quality. The condensation system includes an absorption unit coupled to the reservoir and is configured to receive and mix the boil-off gas with a refrigerant, forming a liquid solution. A distillation unit is coupled to the absorption unit to receive the liquid solution at a supplemented pressure, and is configured to separate the fuel to a gaseous state from the liquid solution. Further, a cooling circuit is configured to receive the fuel in the gaseous state from the distillation unit at the supplemented pressure and a supplemented temperature, and deliver the fuel to the reservoir at a lower pressure and a temperature, with a vapor quality lower than the first vapor quality.

摘要： A system for analyzing health of assets in train is provided. The system includes a sensing unit configured to generate health data of sub-assets. The system also includes a controller in communication with the sensing unit to receive the health data. The controller is configured to display, in a graphical user interface (GUI), a list of assets configurable to allow selection of one asset therefrom. The controller is configured to receive an input command, in the GUI, to select a desired asset from the list of assets for requesting information about health of the desired asset. The controller is configured to display, in the GUI, a visual representation of the desired asset, along with the sub-assets, in response to the input command. The controller is configured to flag, in the GUI, the sub-assets in the visual representation of the desired asset based on the health data of the sub-assets.
