Abstract: A guidance system to assist in alignment between an electric machine and power rails from which the electric machine draws electrical power is disclosed. The power may be drawn by the electric machine from the power rails via an arm having a rotating joint and a rotation sensor that measures the level of rotation of the rotating joint. A controller may receive signals indicative of the rotation angle of the rotating joint and indicate, on a display, the direction and/or magnitude of misalignment between the electric machine and the power rails. The operator of the electric machine can observe the indication of misalignment and use that information to steer the electric machine to the left or the right to better align the electric machine to the power rails. The indication of misalignment may be overlayed on a real-time video display of a path in front of the electric machine.

Abstract: A modular assembly for an exhaust aftertreatment system is provided. The modular assembly includes an inlet portion. The modular assembly also includes a mixing element. The modular assembly further includes a first frusto-conical region diverging from the inlet portion. The modular assembly also includes a selective catalytic reduction assembly provided within a central portion of the housing. The selective catalytic reduction assembly includes a bank of catalysts. The modular assembly further includes a sound suppression element provided within the central portion of the housing and positioned downstream of the selective catalytic reduction assembly. The modular assembly includes a baffle arrangement provided within the central portion of the housing, the baffle arrangement includes a first baffle and a second baffle. The modular assembly also includes a second frusto-conical region converging from the central portion of the housing.
