First Claim
Patent Images
1. 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 comprising:
- a rigid body comprising 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 resilient flexible skirt extending from adjacent a bottom edge of the at least one opaque panel to adjacent a ground surface wherein light emitted from a light emitter into the light radiation zone is substantially maintained within the shroud by the at least one opaque panel and the skirt.

6. A protective shroud for enveloping light radiated by a light emitter used with a sensor system for mapping of a railway track, the railway track including at least a first rail and a second rail, the protective shroud comprising:
-
a rigid body comprising a frame and a plurality of opaque panels connected to the frame; and a resilient flexible skirt extending from a location proximate a bottom edge of the plurality of opaque panels to a location adjacent to a railway surface, wherein the rigid body and the skirt form an enclosure for substantially preventing the escape of light from the enclosure. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
