Patent number: 10156683Abstract: A fiber optic connector assembly incorporates features that improve structural rigidity and the integrity of transmitted signals. These features also facilitate a technique for reversing polarity of the connector assembly with little or no risk of twisting the optical fibers and without requiring the housing assembly to be disassembled. The connector is marked or embossed with transmit and receive connector labels that facilitate visual identification of the polarity of the connector. One side of the duplex connector can be marked with “A” and “B” labels corresponding to the receive and transmit connectors, respectively. The opposite side of the duplex connector can be marked with two “A” labels corresponding to the receive and transmit connectors, respectively. Thus, a user can readily identify whether the connector is configured for “A-B” polarity or “A-A” polarity.Type: GrantFiled: December 15, 2016Date of Patent: December 18, 2018Assignee: Leviton Manufacturing Co., Inc.Inventors: Dennis Manes, Evan Gustafson, Scott Hopper

Patent number: 10139572Abstract: Embodiments of the present disclosure provide techniques for a fiber optic connector assembly configured for polarity reversal in accordance with some embodiments. An assembly may include a housing to receive a fiber optic cable, at least one back post connected with the housing, a ferrule including at least an optical fiber of the fiber optic cable, insertable into the back post, and a connector component comprising a front housing. The front housing may hold at least a portion of the ferrule and detachably couple with the back post. The back post may include a retaining element to provide rotatable coupling of the front housing relative to the ferrule, the back post and the housing. Other embodiments may be described and/or claimed.Type: GrantFiled: April 6, 2017Date of Patent: November 27, 2018Assignee: Leviton Manufacturing Co., Inc.Inventors: Scott Richard Hopper, Evan Gustafson

Patent number: 9971100Abstract: A dust cap for use with a fiber optic connector. The connector has a ferrule comprising an optical fiber. The ferrule has an end portion that includes an end surface of the optical fiber through which optical signals are transmitted. The dust cap includes a cover and wiping material. The cover is removably positionable over the end portion of the ferrule. The wiping material is positioned at least partially inside the cover. The wiping material may be adjacent the end surface of the optical fiber when the cover is positioned over the end portion of the ferrule. The wiping material may be wiped across the end surface of the optical fiber when the cover is positioned over the end portion of the ferrule. The wiping material may be moveable with respect to the end surface of the optical fiber and may wipe thereacross when moved.Type: GrantFiled: March 1, 2016Date of Patent: May 15, 2018Assignee: LEVITON MANUFACTURING CO., INC.Inventors: Bryan L. Sparrowhawk, Bret Taylor, Evan Gustafson, Ryan Moore, Brian Engelhardt

Patent number: 9946035Abstract: A fiber optic connector assembly incorporates features that improve structural rigidity and the integrity of transmitted signals. These features also allow the connector assembly to be accessed easily in high density connectivity environments. These features also facilitate a technique for reversing polarity of the connector assembly with little or no risk of twisting the optical fibers and without requiring the housing assembly to be disassembled. The connector assembly is constructed using a small number of parts, thereby maintaining low maintenance costs while yielding a sturdy structure. A puller can be added to the connector assembly to improve access in congested connectivity applications without increasing the size profile. Chamfered front faces afford a degree of alignment tolerance when plugging the connector assembly into an adapter. Features of the connector assembly can be implemented in both a duplexed housing version as well as a paired simplex clipped version.Type: GrantFiled: September 8, 2016Date of Patent: April 17, 2018Assignee: LEVITON MANUFACTURING CO., INC.Inventors: Evan Gustafson, Scott Hopper

Publication number: 20150080995Abstract: A medical lead may be fabricated using an electrode fixture ((130A)-(130D)) configured to facilitate circumferential and axial alignment between electrodes of the lead. In one example, a method includes positioning an electrode fixture around at least one conductor of a plurality of conductors (122) for a medical lead, wherein the electrode fixture at least partially retains an electrode assembly. The method also includes electrically coupling a portion of the at least one conductor with at least a portion of the electrode assembly at an attachment area defined by the electrode assembly when the electrode assembly is at least partially retained by the electrode fixture.Type: ApplicationFiled: March 15, 2013Publication date: March 19, 2015Applicant: Medtronic, Inc.Inventors: Dale Seeley, Evan Gustafson, Michael Hegland, Seth Humphrys, Darren Janzig, Gerald Lindner
