Abstract: An apparatus and method for detecting faults in a two-wire electric power line isolated from ground includes substantially identical high impedance voltage dividers connected between each of the two wires of the power line and ground, circuits for carrying the output voltages from each voltage divider, a circuit for comparing the output voltages, and outputting a fault signal indicative of a ground fault.

Abstract: Disclosed is a data recorder unit and system for a vehicle. The system includes at least one video camera device configured to generate video data associated with the vehicle and/or its surroundings, and wirelessly transmit at least a portion of the video data. The data recorder unit includes a data recorder enclosure, a data processing unit located in the enclosure and configured to: wirelessly receive at least a portion of the video data from the at least one video camera device, process at least a portion of the video data, and generate processed video data based at least partially on the video data, and at least one storage device comprising at least one crash-hardened memory in communication with the at least one data processing unit and configured to store at least a portion of at least one of the video data and the processed video data.

Abstract: Disclosed is a data recording unit and data recording system for use in connection with a vehicle, such as a train, a locomotive of a train, a railcar of a train, and the like.
