Patent number: 6579914Abstract: A composition for coating an optical waveguide, more specifically, an optical fiber, and optical fibers coated therewith. The coating composition is a radiation curable composition including an aliphatic epoxide, a urethane acrylate oligomer, a reactive diluent, and cationic and free-radical photoinitiators. The cationic photoinitiator acts upon the aliphatic epoxide while the free-radial photoinitiator acts upon the urethane acrylate oligomer. The resulting cured coating forms an interpenetrated polymer network. The properties of coatings in accordance with the invention including the glass transition temperature thereof, can be tailored to achieve advantageous coatings suitable for use as primary coatings and secondary coatings for an optical fiber.Type: GrantFiled: July 14, 2000Date of Patent: June 17, 2003Assignee: AlcatelInventors: Todd W.

Patent number: 5262640Abstract: Mounting of a sensing unit upon the interior surface of a vehicle windshield for detecting the presence of moisture upon the exterior surface and controlling operation of windshield wipers in response thereto is disclosed. The sensing unit comprises a block in which angularly oriented bores are disposed. Light pipes in a first set of the bores communicate with light sources for transmitting light to the outer surface of the windshield, and light pipes in a second set of the bores transmit light reflected from the outer surface to photo-detectors. The lower ends of the light pipes are coplaner with or raised slightly above the surface of the block which is to be secured to the windshield. The block is affixed to the interior surface of the windshield by a double faced adhesive interlayer which both securely adheres the block to the windshield surface and optically couples the light pipes to the windshield.Type: GrantFiled: May 27, 1992Date of Patent: November 16, 1993Assignee: Libbey-Owens-Ford Co.Inventors: Michael B.
