  • Patent number: 9989017
    Abstract: A method of operating a cryogenic fuel system for supplying fuel to an engine is provided herein. A cryogenic fuel pump is operated to pump fuel to be supplied to the engine. At least a portion of the pumped fuel is diverted to be supplied to an accumulator, when a fuel demand of the engine is less than a discharge output of the cryogenic fuel pump. Further, the supply of the pumped fuel from the cryogenic fuel pump to the engine and the accumulator is stopped, when a pressure within the accumulator reaches a first predefined pressure limit. Furthermore, the fuel is supplied to the engine from the accumulator, when supply of the pumped fuel from the cryogenic fuel pump to the engine and the accumulator is stopped.

  • Patent number: 9990552
    Abstract: A fatigue monitoring system is disclosed for use with a machine. The fatigue monitoring system may have an input device configured to generate a first signal indicative of an activity performed by a machine operator, a scanning device configured to generate a second signal indicative of a recognized characteristic of the machine operator, and a warning device. The fatigue monitoring system may also have a controller in communication with the input device, the scanning device, and the warning device. The controller may be configured to determine a time between generations of the first signal, to make a comparison of the recognized characteristic with a threshold characteristic, and to selectively activate the warning device based on the time or the comparison.

  • Patent number: 9939301
    Abstract: A system is disclosed for use with a machine having an engine with at least one cylinder. The system may have at least one injector configured to inject fuel into the at least one cylinder, and a controller in communication with the at least one injector. The controller may be configured to determine an injection duration of the at least one injector. The controller may also be configured to calculate a fuel consumption value for the machine based on the injection duration.

  • Patent number: 9932048
    Abstract: A power system for a locomotive. The power system has a first power unit, a second power unit, a first inverter configured to power the first power unit or the second power unit, a second inverter configured to power the first power unit or the second power unit. Further the power system has a first controller selectively coupled to one of the first inverter or the second inverter to control the operation of the first inverter or the second inverter and a second controller selectively coupled to one of the first inverter or the second inverter to control the operation of the first inverter or the second inverter.

  • Patent number: 9561811
    Abstract: A railroad control system is disclosed for a network of trains. The system may include a centralized control system configured to transmit trip parameters for each train in the network. The system may include an energy manager in communication with the centralized control system and located onboard each train. The energy manager may be configured to determine an energy profile for a consist of the train based on the trip parameters. The system may further include a consist manager located onboard the consist and configured to determine a distribution of the energy profile for each locomotive of the consist. The system may also include one or more locomotive managers, each associated with a locomotive of the consist, and configured to determine a power configuration of the one locomotive based on the distribution of the energy profile and known parameters of the locomotive.
