Publication number: 20240179497Abstract: Example systems, methods, and computer-readable media are disclosed. In an example method, a first outbound text message is transmitted via a message broker of a messaging platform from a client to a plurality of recipients. In response to the first outbound message, a plurality of inbound text messages is received, via the message broker, from the plurality of recipients. A first grouping of the plurality of inbound text messages is determined, the first grouping associated with one or more recipients of the plurality of recipients. The first grouping is presented to the client. A second outbound text message is transmitted, via the message broker, from the client to the one or more recipients of the plurality of recipients. The second outbound text message is generated based on the first grouping. The message broker is in communication with a first messaging service and a second messaging service different from the first messaging service.Type: ApplicationFiled: September 5, 2023Publication date: May 30, 2024Applicant: Community.com, Inc.Inventors: Alec RUBIN, Skylar KERZNER, Nate SALETAN, Lars PERKINS, Barry STEINGLASS, Joshua ROSENHECK, Tomas KOCI, Matthew PELTIER

Patent number: 7639862Abstract: An automated computer-controlled method and apparatus for measuring the quality or fineness of a pigment dispersion sample, comprising placing the pigment dispersion at the deep end of the tapered path of a Hegman gage block, placing the Hegman gage block in a holder in a motorized drawdown device that draws the scraper along the length of the tapered path at an angle and to at a contact pressure and at a controlled rate, thereby creating a tapered film sample of paint whose thickness tapers from a maximum thickness of 100 micrometers to a minimum thickness of zero. An illuminator assembly illuminates the sample with a substantially collimated light source at an intensity level and the light reflected from the sample is collected by a lens onto a photodetector array in a digital camera. After a time interval the camera acquires an image of the sample.Type: GrantFiled: December 9, 2005Date of Patent: December 29, 2009Assignee: E.I. du Pont de Nemours and CompanyInventors: Robert Vincent Canning, Jr., Scott Richard Mehr, Barry Rubin, Thomas William Simpson, III, Douglas Ray Stilwell

Patent number: 7620211Abstract: An image analysis method to quantify visual showthrough of printed images on the reverse face of planar objects, such as paper. An illumination level is set using a white reference object. A white reference image is stored in a computer memory. An image of a planar object having a printed image on the reverse face is stored in a computer memory. A pixel by pixel ratio of the two images is calculated and a mean value of the ratios is calculated to characterize the visual showthrough. The measurements are substantially independent of both the illumination level and image shading.Type: GrantFiled: April 7, 2004Date of Patent: November 17, 2009Assignee: E.I. du Pont de Nemours and CompanyInventors: Richard Walker Browne, Robert V. Canning, Jr., Michael H. Evans, Robert William Johnson, Barry Rubin, Douglas Ray Stilwell

Publication number: 20050222825Abstract: This invention relates to computing numerical solutions of linear systems of equations, specifically to implementing preconditioning of the coefficient matrix of such a system. The preconditioning applies to any coefficient matrix, dense or sparse, based on the solutions of a physical problem of unknown functions, commonly referred to as basis or interpolation functions, where the basis function spans more then one mesh element. Examples of such linear systems can result from, as examples, an electromagnetic analysis of printed circuit boards or field scattering in radar applications, fluid mechanics and acoustics. A method and system to compute a preconditioner for a coefficient matrix A that is compatible with the linear system of equations that provides basis function support over at least two mesh elements. Coupling of the preconditioner between partitions of a portioned mesh representation is only through basis functions at the partition boundaries.Type: ApplicationFiled: March 31, 2004Publication date: October 6, 2005Inventors: Peter Feldmann, Jason Morsey, Barry Rubin

Publication number: 20050218908Abstract: The present invention relates to a method for analyzing the noise prediction within one or more electrical circuits, wherein the electrical circuits have a power mesh grid distribution system that feeds power levels to the electrical circuits that are connected by signal wires. After identifying a driver and receiver electrical circuit to be analyzed, a power block is generated that is associated with the driver and receiver electrical circuit by partitioning an area of a power mesh grid distribution system into a power block that can be modeled with lossy transmission line techniques. Next, signal wires situated between the driver and receiver electrical circuits are partitioned into signal blocks that can be modeled with lossy transmission line techniques. Lastly, the power blocks and signal blocks associated with the electrical circuits are analyzed in order to predict the noise performance within the electrical circuits.Type: ApplicationFiled: April 6, 2004Publication date: October 6, 2005Inventors: Alina Deutsch, Gerard Kopcsay, Byron Krauter, Barry Rubin, Howard Smith

Patent number: 5325301Abstract: The present invention relates broadly to a method of image analysis for analyzing the texture of a surface, and to a saxony-type carpet having a tightly tailored surface texture characterized by this method. The method employs a model based on a second order co-occurrence matrix model which calculates a set of textural parameters for image classification. This co-occurrence matrix model examines the statistics of the spatial relationship between gray levels in a homogeneously textured image with calculated textural features which represent measures such as homogeneity and contrast. The method of the present invention uses this model to construct a set of normalized textural parameters from the textural parameters and calculates a value for the normalized textural parameters from this set, where the normalized textural parameters are related to the physical properties of the surface, such as pile lay of a carpet.Type: GrantFiled: March 27, 1992Date of Patent: June 28, 1994Assignee: E. I. Du Pont de Nemours and CompanyInventors: Warren F. Knoff, Michael J. Merrill, Barry Rubin, Akhileswar G. Vaidyanathan, James E. Van Trump, Theresa A. Weston

Patent number: 4656663Abstract: An automated system is used for the inspection of a transparent film which has been metallized by vaporizing a metal so that it impacts the film's surface at a preselected angle, wherein the metallized film sample is illuminated with a light source, and the transmitted light is passed through a microscope to a video camera, which produces a videoscan. The videoscan is digitized, stored in a computer memory, and processed pixel by pixel by the computer which calculates asperity height distribution from the number and lengths of metallizing shadows caused by asperities on the film surface. This method is especially useful for inspecting film to be used for recording devices, especially for video tapes, where accurate information on the asperity height distribution is required.Type: GrantFiled: August 6, 1984Date of Patent: April 7, 1987Assignee: E.
