  • 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.

  • Publication number: 20160264152
    Abstract: A locomotive assembly is provided. The locomotive assembly includes a locomotive having a power source configured to generate mechanical power. The locomotive also includes a generator configured to generate electrical power. The locomotive further includes an electric motor configured to provide motive power to the locomotive. The locomotive assembly also includes an auxiliary vehicle haying a power receiving device configured to receive electrical power from an external power grid. The auxiliary vehicle also includes a transformer and a circuit breaker. The circuit breaker and the transformer are configured to control the electrical power received by the power receiving device. The auxiliary vehicle further includes a cooling system configured to control a temperature of the transformer. The transformer is further electrically coupled to the electric motor of the locomotive to selectively provide electrical power to the locomotive.
