摘要： A shutter for controlling radiation exposure includes a rotatable member. The rotatable member is rotatable between an open position and a closed position. The rotatable member includes a passageway, wherein the passageway is positioned to receive radiation in the open position and is not positioned to receive radiation in the closed position. In the closed position, the rotatable member may substantially block or absorb the radiation. The passageway may collimate the radiation into a beam of radiation. The rotatable member may include a plurality of passageways positioned to receive radiation in the open position. The rotatable member may be rotatable between a plurality of open positions, each open position corresponding to at least one passageway. The open positions may align the source of radiation with different passageways in the rotatable member to form a different beam shape, a different number of beams, a different beam direction, or combinations thereof.

摘要： A system for inspecting railroad ties in a railroad track includes a light generator, an optical receiver and a processor. The light generator is oriented to project a beam of light across the railroad track while moving along the railroad track in a travel direction. The optical receiver is oriented to receive at least a portion of the beam of light reflected from the railroad track and configured to generate image data representative of a profile of at least a portion of the railroad track. The processor is configured to analyze the image data by applying one or more algorithms configured to find boundaries of a railroad tie and determine one or more condition metrics associated with the railroad tie.

摘要： A method to increase the accuracy of the interpolation of railroad mileposts is disclosed. Based upon image data and data provided in customer track charts, reference points are selected along the track, and their location is verified using GPS data. Once verified, the locations of various points between the reference points are determined using mathematical interpolation.

摘要： A method of operating a radiation inspection system includes identifying a regulatory region along a predetermined path where public access is restricted based upon criteria other than radiation exposure, measuring a radiation exposure level from a radiation source of the radiation inspection system within the regulatory region, irradiating a target within the regulatory region using the radiation source and without erecting a physical barricade, and determining a restricted area around the radiation source. The restricted area corresponds to an area where a radiation exposure rate exceeds a predetermined threshold. The radiation exposure rate may be determined by the radiation exposure level from the radiation source and a speed of the radiation inspection system. The method may include operating the radiation inspection system to dynamically adjust the restricted area so that it does not extend beyond the regulatory region. The radiation inspection system may be moveable along the predetermined path.

摘要： A self-unloading aggregate train including a plurality of hopper cars and an individual conveyor belt located beneath each hopper car. The head pulley at one end of each individual conveyor belt may rotate the belt in a direction from a tail pulley towards the head pulley. The head pulley of one hopper car is positioned above and adjacent of a tail pulley of the adjacent hopper car. This arrangement of hopper cars with individual conveyor belts may be used to unload material from the train. The individual conveyor belts may be adapted so that the trajectory of material transfer to an adjacent belt is near the pivot point between the adjacent hopper cars. The individual conveyor belts may have a substantially constant slope. The hopper of the hopper cars may also be configured with a substantially constant slope that matches the slope of the individual conveyor belts.
