摘要： A system and method for inspecting a railway track using sensors oriented at an oblique angle relative to a rail vehicle on which the system is traveling. The orientation of the sensors allows for different data to be gathered regarding a particular rail including rail design specifications (gathered based on manufacturer markings detected and analyzed by the system), rail seat abrasion values based on direct measurement of rails from the oblique angle, and other analysis of rail features including joint bars, rail welds, bond wires, rail holes, and broken rails. The use of an air blower, ducts, and one or more air distribution lids over the sensors helps remove debris from blocking the sensors and structured light generators.

摘要： A wind turbine foundation and method for making a wind turbine foundation. The wind turbine foundation preferably includes a core member including a substantially cylindrically-shaped main body, a first outer flange extending out from the main body along an upper section of the core member, and a second outer flange extending out from the main body along a lower section of the core member, and a plurality of radial girders connected to the first outer flange and the second outer flange and radiating out from the core member.

摘要： A protective shroud for enveloping light radiating from a light emitter used with a sensor system for mapping of a railway track. The protective shroud includes: a rigid body having a frame and at least one opaque panel connected to the frame, the rigid body defining at least a first portion of a light radiation zone; and a skirt formed of high density fibers extending from adjacent a bottom edge of the at least one opaque panel to adjacent a ground surface.
