Patent number: 11930133Abstract: A device may determine that a failure occurred in an emergency call between a public-safety answering point (PSAP) and a first user device associated with an emergency caller, and may identify, based on determining the failure, one of a first option, a second option, or a third option for redirecting an emergency callback to a contact of the emergency caller. The device may cause, when the first option is identified, the emergency callback to be redirected to a second user device associated with the contact of the emergency caller, and may cause, when the first option is identified, a bearer path to be established between the PSAP and the second user device for the emergency callback.Type: GrantFiled: December 13, 2021Date of Patent: March 12, 2024Assignee: Verizon Patent and Licensing Inc.Inventors: Kashif Khan, Danysel Barthelme, Ronald E. Collier, II, Ertao Li, Steve L. Padilla, Gaurav Patel, Shawn R. Pugh, Shujaat Ali Siddique, Daniel L. Walker, John Cao Vinh Nguyen

Publication number: 20160052976Abstract: We described a novel system of targeted cell therapy with a protein toxin, such as anthrax toxin, that has been modified to re-direct it to a desired cell target instead of its natural cell target. The system can be used for, e.g., targeted killing of undesired cells in a population of cells, such as cancer or overly active immune system cells.Type: ApplicationFiled: February 18, 2015Publication date: February 25, 2016Inventors: Adva Mechaly, Andrew J.

Patent number: 6511746Abstract: Microfibers have been manufactured from dissolved cellulose, from which threads, yarns, and fabrics can be made. These cellulosic microfibers may be used to produce fabrics with the very soft feel that is characteristic of microfiber fabrics, and the water absorbency and comfort of cellulosic fabrics. Furthermore, since the microfiber diameter may be 2 &mgr;m or smaller (about the same size as dust particles and small oily droplets), these fabrics have an exceptional ability to remove dust and oil droplets from surfaces and gas streams, and are therefore useful in filter media. The novel microfibers may be manufactured by the continuous flow of dissolved cellulose through a converging die. Imposing orientation in the incipient microfiber prior to or during crystallization of the cellulose produces continuous fibers of substantial aspect ratio, without significant entanglement.Type: GrantFiled: September 26, 2000Date of Patent: January 28, 2003Assignee: Board of Supervisors of Louisiana State University and Agricultural and Mechanical CollegeInventors: John R. Collier, Ioan I. Negulescu, Billie J. Collier

Patent number: 6220083Abstract: Elongational viscosity may be easily and accurately measured by observing the flow characteristics of a high viscosity fluid through a hyperbolic or semi-hyperbolic die, without lubrication of the fluid flowing through the die. The effects of developing orientation in the fluid during converging elongational flow are so strong that the shearing contribution becomes negligible in comparison, eliminating the need for lubrication during measurements.Type: GrantFiled: October 14, 1998Date of Patent: April 24, 2001Assignee: Board of Supervisors of Louisiana State University and Agricultural and Mechanical CollegeInventor: John R. Collier

Patent number: 5718802Abstract: Novel fiber bundles may be produced as a by-product of sugar cane or other plants. These fiber bundles may be spun into a yarn, or formed into a non-woven mat. The non-woven mat is useful, for example, as a biodegradable geotextile for inhibiting erosion while allowing plants to become established on roadsides, or in other applications. Sugar cane fiber bundles were extracted from the Tilby-separated rind of cane stalks using alkaline treatments. The amount of lignin removed was dependent on alkaline concentration and time, pressure of treatment, and steam explosion conditions if employed. Agitation and vigorous boiling affected the lignin removal. Alkali concentration significantly affected the mechanical properties of the fiber bundles. Tenacity, toughness, and linear density were higher for the fibers extracted at lower alkali concentration. Bending rigidity and hysteresis of these fibers were also higher. This process is also expected to work with other plant stalks having a high lignin content.Type: GrantFiled: January 9, 1995Date of Patent: February 17, 1998Assignee: Board of Supervisors of Louisiana State University and Agricultural and Mechanical CollegeInventors: John R. Collier, Billie J. Collier

Patent number: 5387383Abstract: Rayon/nylon and other sheath/core composite fibers or other materials, with good adhesion between sheath and core resulting from an adhesion promoter. The adhesion promoter is difunctional and sterically hindered. Fumaric acid and terephthalic acid are preferred adhesion promoters for the composite fibers or other materials, because each compound has both difunctionality and steric hinderance, allowing either to form covalent bonds to both the sheath and the core. Fibers produced in accordance with this invention may be used to produce fabrics which have the strength and wrinkle resistance shown by a number of synthetic fibers, but with the water absorption characteristics of natural fibers such as cotton.Type: GrantFiled: December 13, 1993Date of Patent: February 7, 1995Assignee: Board of Supervisors of Louisiana State University and Agricultural and Mechanical CollegeInventors: John R. Collier, Billie J. Collier

Patent number: 5357784Abstract: A novel method and apparatus for measuring elongational viscosity are disclosed. It is shown that in a hyperbolic or semi-hyperbolic die geometry with lubricated flow, the elongational viscosity of a fluid can be obtained from pressure drop--flow rate data. Experimental data for polypropylene as core and polyethylene as skin material, and the calculated extensional viscosities are presented. Alternative embodiments of the novel elongational rheometer are described, including alternatives suitable for biaxial flow.Type: GrantFiled: August 4, 1993Date of Patent: October 25, 1994Assignee: Board of Supervisors of Louisiana State University and Agricultural and Mechanical CollegeInventor: John R.
