Patent number: 11675120Abstract: Embodiments of the present disclosure generally relate to light fixtures and luminaires configured to emit light. According to one aspect, an optical waveguide includes a first waveguide portion and a second waveguide portion adjacent to and separate from the first waveguide portion. The waveguide portions include light coupling portions that are at least partially aligned and adapted to receive light developed by a light source. The first waveguide portion further has a first major surface with light direction features and a second major surface opposite the first major surface. The second waveguide portion further has a third major surface proximate the second major surface with an air gap disposed therebetween and a fourth major surface opposite the third major surface wherein the fourth major surface includes a cavity extending therein.Type: GrantFiled: June 14, 2021Date of Patent: June 13, 2023Assignee: IDEAL Industries Lighting LLCInventors: Kurt S. Wilcox, Christopher D. Strom, Jin Hong Lim, Zongjie Yuan, Mark Boomgaarden, Randall Levy Bernard, John W. Durkee, Craig D. Raleigh, Joseph P. Chobot

Patent number: 9737694Abstract: A method of fabrication of a medical balloon, and a balloon device useful for various medical balloon procedures, such as gastrointestinal, vascular, reproductive system, urinary system and pulmonary applications. At least two layers of a thermoplastic film are sealed at their peripheral edges and heat sealed at one or more locations inside an area enclosed by the sealed edges at predetermined locations, in one implementation of the balloon device. Such configuration enables the balloon to articulate to a desired shape upon inflation, with the desired shape being selected to accommodate a specific medical application.Type: GrantFiled: October 27, 2016Date of Patent: August 22, 2017Assignee: POLYZEN INC.Inventors: Tilak M. Shah, Christopher D. Strom

Patent number: 8853326Abstract: An RF-weldable thermoplastic elastomer composition, including a thermoplastic elastomer of non-RF-weldable or poorly RF-weldable character, e.g., a styrenic copolymer/olefinic polymer blend thermoplastic elastomer, and polyol in an amount that is less than 1% by weight, based on weight of the thermoplastic elastomer, and is effective to enhance RF-weldability of the thermoplastic elastomer. The composition may also contain an antistatic ionomer, in an amount that is less than 15% by weight, based on weight of the thermoplastic elastomer. Films of such composition are usefully employed to form RF-welded film articles, such as blood bags, IV fluid bags, glucose bags, urine bags, stool bags, biological sample bags, pouches, covers, and liners.Type: GrantFiled: July 20, 2012Date of Patent: October 7, 2014Assignee: Polyzen Inc.Inventors: Tilak M.
