Publication number: 20240080594Abstract: A speaker can have a main body with a generally spheroidal shape, which can be supported standing on its end. The speaker can include a subwoofer that faces forward. A plurality of mid-range drivers can be distributed around the sub-woofer, facing generally forward and radially outward. A plurality of tweeters can be distributed around the sub-woofer, facing generally forward and generally outward. The outer housing portion of the speaker can be covered with a fabric material. A user interface ring 162 can be touch sensitive to receive input, and can have a plurality of lights that can be illuminated separately to convey information to the user.Type: ApplicationFiled: July 5, 2023Publication date: March 7, 2024Inventors: Timothy David Williamson, Peter Joseph Hamblin, Maximilian Vincent Wozniak, Robert James Wilson, Wilson E.

Patent number: 9975923Abstract: The present invention provides methods and compositions comprising a chimeric norovirus capsid protein comprising a norovirus VP1 major capsid protein backbone comprising a norovirus epitope selected from the group consisting of: a) Epitope A; b) Epitope B; c) Epitope C; d) Epitope D; e) Epitope E; f) Epitope F; and g) any combination of (a) through (f) above, wherein the norovirus epitope is from a norovirus strain that is different from the norovirus VP1 major capsid protein backbone.Type: GrantFiled: March 14, 2014Date of Patent: May 22, 2018Assignee: The University of North Carolina at Chapel HillInventors: Ralph Steven Baric, Lisa Chon Lindesmith, Kari Moore Debbink, Eric Francis Donaldson, Jesica Anne Swanstrom

Patent number: 9042017Abstract: Method and apparatus to generate a composite far field beam having a central null and discrete cylindrical symmetry. A phased array of Gaussian beams was used to form an annular far-field pattern as opposed to the normal peaked pattern in most phased arrays. This annular pattern arises from the radial symmetry of the polarization in each beam. Beams opposite one another in the annulus are polarized in the same direction but are 180° out of phase. This causes the center portion of the beam to be a null rather than a peak.Type: GrantFiled: March 24, 2014Date of Patent: May 26, 2015Assignee: The United States of America as Represented by the Secretary of the NavyInventors: Michael Johnny Wardlaw, Ramesh Kumar Shori, Ralph Steven Kurti

Publication number: 20100057498Abstract: A method includes receiving in a computer an electronic file that represents a claim paid by an insurance company. The electronic file indicates whether the claim involves another insurance company, and whether the other company has admitted or is likely to admit liability for the claim. The computer makes a triage decision to send a demand letter to the other company and then defer action if the other insurance company is likely to admit or has admitted liability. Otherwise, the computer sends the demand letter and routes the file for immediate follow-up.Type: ApplicationFiled: September 4, 2008Publication date: March 4, 2010Inventors: Gary D. Stephen, Nancy L. Huff, Ralph Steven Bush, Susan M. Kucia, Hans Peter Kingenberg

Patent number: 7093873Abstract: Apparatus for storing items within a vehicle compartment that can be operated single-handedly, are provided. A cover is pivotally attached to a vehicle compartment floor (or to a base secured to a vehicle compartment floor) and is movable between a closed position in overlying, face-to-face relation with the floor and an open position wherein the cover is disposed substantially transverse to the floor. A wall is pivotally attached to the cover front side and is movable between a stored position in face-to-face relation with the cover front side and an operative position disposed substantially transverse to the base and to the cover. A spring is configured to urge the wall to a predetermined position when the cover is moved from a closed position to an open position. An elastic strap is secured to the cover and is configured to secure articles placed between the elastic strap and the cover.Type: GrantFiled: August 19, 2004Date of Patent: August 22, 2006Assignee: Collins & Aikman Products Co.Inventors: Öivind Nilsrud, Per Erlandsson, Ralph Steven Szejbach

Patent number: 6766259Abstract: A system and a method are provided for detecting fiber damage in a dialyzer. The system may have a device which may transmit a gas into an interior of a fiber within a dialyzer. The temperature of the gas may be different than a temperature of the dialyzer. A thermal imaging camera may detect a temperature difference at a surface of the fiber where the gas may be escaping. The thermal imaging camera may be connected to a monitor which enables a user to view a location of the difference in temperature. As a result, the user may locate the damaged area of the fiber. The user may then repair the damaged area.Type: GrantFiled: July 29, 2002Date of Patent: July 20, 2004Assignee: Baxter International Inc.Inventors: William Brandon Padgett, Ralph Steven Kesler, Michael E. Cameron, Roger D. Horton
