Protective shroud for enveloping light from a light emitter for mapping of a railway track
First Claim
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;
a resilient flexible skirt extending from adjacent a bottom edge of the at least one opaque panel to adjacent a ground surface;
at least one light emitter connected to the rigid body adjacent a top edge of the rigid body to emit light radiation into the light radiation zone; and
at least one sensor connected to the rigid body adjacent the top edge of the rigid body to sense the light emitted from the at least one light emitter.

Abstract
A protective shroud is provided 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; 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; at least one light emitter connected to the rigid body adjacent a top edge of the rigid body to emit light radiation into the light radiation zone; and at least one sensor connected to the rigid body adjacent the top edge of the rigid body to sense the light emitted from the at least one light emitter.

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; 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; a first light emitter connected adjacent a top edge of the rigid body for emitting light radiation inside the enclosure toward a first rail of a railway surface; and a first sensor connected adjacent the top edge of the rigid body for sensing light emitted from the first light emitter. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
