Patent number: 8702326Abstract: A fiber optic assembly includes first and second fiber optic ribbons and a splice protector. Each of the first and second fiber optic ribbons includes a plurality of optical fibers coupled in a substantially flat arrangement, where the optical fibers are aligned side-by-side with one another. The optical fibers of the first ribbon are fusion spliced with the optical fibers of the second ribbon such that the spliced ribbons at the splice have a common lengthwise axis, widthwise axis orthogonal to the lengthwise axis, and thickness axis orthogonal to the lengthwise and widthwise axes. The splice protector supports the optical fibers of the first and second fiber optic ribbons that are spliced to one another at the splice. The splice protector includes an ultra-violet light (UV-) curable adhesive that provides a flexible support for the splice, and is at least half as flexible when cured over the splice as the first and second ribbons in bending about the widthwise axis.Type: GrantFiled: June 7, 2012Date of Patent: April 22, 2014Assignee: Corning Cable Systems LLCInventors: Michael T. Faulkner, Lars K. Nielsen

Publication number: 20130259434Abstract: A fiber optic cable assembly includes a fiber optic cable, a tether, and an overmold. The fiber optic cable includes an optical fiber, a strength member, and a jacket, where the jacket includes an interior portion contacting the strength member and an exterior portion adjoining the interior portion. The interior and exterior portions of the jacket both include polyethylene, and the exterior portion further includes an additive that is not in the interior portion. The tether is coupled to the fiber optic cable at an attachment point. The optical fiber or another optical fiber spliced to the optical fiber, diverges from the fiber optic cable via the tether. The overmold encloses the attachment point and is attached directly to a discrete section of the exterior portion of the jacket proximate to the attachment point. The additive facilitates bonding of the overmold to the discrete section.Type: ApplicationFiled: March 29, 2012Publication date: October 3, 2013Inventors: Anne G. Bringuier, Julian L. Greenwood, III, Gregory A. Lochkovic, Alvin J. McDonald, Lars K. Nielsen, Hieu V. Tran

Patent number: 8173427Abstract: A method is provided for producing a population of post-mitotic cells of the neutrophil lineage, which method comprises the ex vivo steps of: (a) providing a population of cells comprising neutrophil progenitor cells; and (b) culturing the population of cells in an animal cell culture medium comprising (i) one or more early acting cytokines and (ii) one or more cytokines that differentiate said progenitor cells into a neutrophil specific lineage, under conditions of low oxidative stress, the culture medium being agitated when the cells are at a cell density at which oxygen transfer via the surface of the culture medium is insufficient for growth of the progenitor cells and the progeny thereof under static conditions, to produce a population of post-mitotic cells of the neutrophil lineage. The resulting population of cells can be used to increase the number of neutrophils in a patient.Type: GrantFiled: July 23, 2007Date of Patent: May 8, 2012Assignee: The University of QueenslandInventors: Lars K.

Patent number: 7658549Abstract: A pre-connectorized fiber optic distribution cable assembly includes a plurality of optical fibers and at least one mid-span access location along the length of the distribution cable. At least one of the optical fibers is accessed, terminated and then connectorized at the mid-span access location to an optical connector disposed within a receptacle. The mid-span access location, the accessed, terminated and connectorized optical fiber, the optical connector and at least a portion of the receptacle are encapsulated with a protective overmolded shell. A tether including at least one optical fiber connectorized at a first end of the tether is optically connected to the optical connector through the receptacle. A second end of the tether opposite the first end terminates in a network optical connection terminal, thereby compensating for a span length measurement difference between the actual location of the mid-span access and the desired location of the optical connection terminal.Type: GrantFiled: July 31, 2007Date of Patent: February 9, 2010Assignee: Corning Cable Systems LLCInventors: Robert B.
