Publication number: 20240056730Abstract: A ceiling-mounted microphone array enclosure includes a room panel and a top panel. The room panel includes a border of solid material that surrounds a central sound permeable area having sound permeable perforations. The top panel is connected to the room panel through connectors arranged along the border of solid material. The top panel can have sides and be connected to the room panel such that there is a gap to permit improved airflow, or sides of the top panel can connect directly to the bottom panel without a gap. A microphone array and other electronic components can be arranged within the enclosure and then ceiling mounted within a ceiling grid. Multiple differently sized room panels can be manufactured in such a way that they can connect directly to the top panel. To reduce manufacturing costs, each of the top panels can be manufactured having the same size and design.Type: ApplicationFiled: August 7, 2023Publication date: February 15, 2024Inventors: Derek Louis Graham, Pichet Ong, William Deberard, Feng (Alan) Zhao

Patent number: 5367319Abstract: A method and apparatus for forestalling counterfeiting is disclosed which allows a counterfeit document to be identified relatively easily by an average person. The present invention employs a fluid jet applicator to record a unique, random pattern on each of a set of documents (e.g., paper currency, corporate or government bonds or any other document or important paper). Thus, a fluid jet applicator is controlled to produce a truly unique pattern on a set of original documents. Any counterfeiter who merely copies one (or a number) of the genuine documents would be left with a plurality of identical (i.e., non-unique) documents which may then be readily identified by a recipient as not being genuine.Type: GrantFiled: July 30, 1992Date of Patent: November 22, 1994Assignee: Burlington Industries, Inc.Inventor: Louis A. Graham

Patent number: 4849768Abstract: The fluid jet applicator of the present invention utilizes a piezoelectric crystal to artificially stimulate the fluid supply chamber with coherent acoustic energy to pruposely generate and exploit the acoustic standing waves therein. As a result, although sized droplets will be formed at substantially the same frequency from each orifice, individual droplets will be formed so as to be out of phase with its adjacent neighbors in accordance with the standing acoustic wave pattern. By selecting only a very short print time, e.g., such that only one or two drops are formed within such a time and by controlling the frequency of such print time, a wide range of aesthetically appealing, unique, random interference of patterns can be created. Patterns closely simulating natural wood grains including knot holes can be readily produced by the present invention. More, the present invention allows patterns to be modified with relative ease and remarkable flexibility.Type: GrantFiled: May 4, 1988Date of Patent: July 18, 1989Assignee: Burlington Industries, Inc.Inventor: Louis A. Graham

Patent number: 4841307Abstract: Fluid jet printing apparatus having a fluid jet printhead and a pair of substrate positioning rolls for moving the substrate between a position below the printhead for printing on the substrate and a position removed from the printhead enabling access to the printhead. Two or more printing stations, each having a fluid jet printhead and substrate positioning rolls, are serially aligned in the direction of movement of the substrate to print different fluids on the substrate. Idler rolls are arranged to effect printing on opposite sides of the substrate at the respective printing stations. The direction of travel of the substrate past the printhead may be in a direction to first pass the catcher and then the droplet streams thereby minimizing or eliminating the tendency of particles to enter the region of the electrodes.Type: GrantFiled: December 4, 1987Date of Patent: June 20, 1989Assignee: Burlington Industries, Inc.Inventor: Louis A. Graham

Patent number: 4829793Abstract: A fluid jet applicator is disclosed which senses orifice plate fluid pressure and the fabric substrate speed and electronically controls the flow of fluid by modulating fluid pressure in accordance with the speed and characteristics of the fabric substrate. In this fashion, a highly uniform solid shade is applied across the width of the fabric. The uniformity of the applied solid shade is limited only by the uniformity of the orifices in the applicator orifice plate. Additionally, by operating at higher fluid pressures than electrostatic fluid jet applicators, the present invention is significantly more productive than such electrostatic applicators.Type: GrantFiled: December 24, 1987Date of Patent: May 16, 1989Assignee: Burlington Industries, Inc.Inventors: Joseph P. Holder, Michael I. Glenn, Bobby L. McConnell, Louis A. Graham

Patent number: 4797687Abstract: The electrostatic fluid jet applicator of the present invention achieves patterning effects with an applicator designed to provide a uniform solid application of liquid onto substrates. The applicator requires no digital memory device to store extensive image data defining patterns to be printed and includes a single ganged charging electrode which is utilized to simultaneously charge (or not charge) droplets emanating from a linear array of orifices. The applicator generates patterning effects primarily by controlling the application of charging voltage to the single electrode and by controlling the print time.Type: GrantFiled: March 16, 1987Date of Patent: January 10, 1989Assignee: Burlington Industries, Inc.Inventors: Joseph P. Holder, Michael I. Glenn, Bobby L. McConnell, Louis A. Graham

Patent number: 4725851Abstract: An orifice plate mounting assembly includes a manifold having an interior cavity defining an elongated slot and fluid communication therewith and a pair of exterior vertical guide surfaces bracketing a recessed substantially planar surface surrounding the elongated slot. A pair of clamping members each having a clamp body, a clamping arm extending horizontally outwardly from the clamp body and defining substantially planar contact surfaces, and hinge elements are provided to horizontally position the planar contact surface of each clamping arm in planar contact with the respective portion of the planar orifice plate laterally of the linear array of orifices. Suitable securing elements bridge the manifold assembly in each clamp body to cause each planar contact surface to exert a clamping force against the orifice plate so as to, in turn, exert a clamping force between the planar orifice plate and the recessed planar surface.Type: GrantFiled: June 26, 1986Date of Patent: February 16, 1988Assignee: Burlington Industries, Inc.Inventors: Richard Sutera, Louis A. Graham, James D. Rouch

Patent number: 4313732Abstract: Dyes are fixed in an indigo-dyed cellulosic fabric, such as denim, in order to improve its washfastness, by applying an aqueous solution of a fixative compound then drying and curing the thus treated fabric in the disclosed process. Suitable fixatives include colorless and colored dihalo-s-triazine reactive dyes. Cellulosic fabrics thus treated retain their original indigo color even after repeated launderings.Type: GrantFiled: December 2, 1980Date of Patent: February 2, 1982Assignee: Burlington Industries, Inc.Inventors: Edward W. Teague, Louis A. Graham, Bobby L. McConnell
