  • Publication number: 20240123460
    Abstract: Disclosed are methods, systems and computer program products for producing and applying a spray foam producing mixture onto a surface, and imaging a spray cone, or the applied surface, using an infrared or an optical imaging device to capture an image, and then determining, based on the captured image, if a defect that requires correction exists in the spray cone or in the applied surface; and optionally, in response to determining that a defect requiring correction exists, modifying a process parameter in producing or applying spray foam.

  • Publication number: 20240025094
    Abstract: Disclosed are methods, systems and computer program products for producing polyurethane foam, and then imaging the polyurethane foam at or just after the outlets while the foam is being produced, above the surface of the foam at an angle greater than zero to less than degrees relative to the surface of the foam, or after the foam is cut but before it has cooled to room temperature, using an infrared or an optical imaging device, to capture an image of the polyurethane foam, and determining, based on the captured image, if a defect that requires correction exists in the polyurethane foam; and optionally, in response to determining that a defect requiring correction exists, modifying a process parameter in producing the polyurethane foam.

  • Patent number: 11854053
    Abstract: A method of producing a graphical depiction of a value of a property of a material is provided. The method comprises generating, by a processing unit, a plot defining a geometric shape, a first axis comprising a plurality of first variables, and a second axis comprising a plurality of second variables. The processing unit generates a plurality of points arranged in a matrix based on the first variables and the second variables, each of the points define a value of a property of a material formed by a combination of one of the first variables and one of the second variables. An output device displays a visual representation of the respective values of the property of the material at least two of the plurality of points in a range of indicia. The range of indicia represents a comparison of the respective value of the property and a constraint.

  • Publication number: 20220324142
    Abstract: Disclosed are methods, systems and computer program products for producing rigid foam board, comprising: depositing a foam producing mixture on a facer as it travels along a conveyor; producing a rigid foam board via an exothermic reaction; imaging the rigid foam board after it is produced but before it has cooled to room temperature, using an infrared or an optical imaging device, to capture an image of the rigid foam board; receiving a signal comprising the captured image from the imaging device to a computing device; determining, based on the captured image, if a defect that requires correction exists in the rigid foam board; and optionally, in response to determining that a defect requiring correction exists, modifying a process parameter in producing rigid foam board.

  • Publication number: 20220277406
    Abstract: A computer-implemented method of optimizing an industrial process includes comparing current environmental condition data to historic environment condition data for at least one day preceding a specified day. The method also includes determining a visual state from a plurality of visual states for the at least one day based on the comparison between the current environmental condition data and the historic environment condition data. The method further includes generating a calendar interface comprising a plurality of days preceding the specified day and corresponding to a plurality of visual representations. The method further includes generating a graphical user interface comprising historical data for at least one type of industrial process.

  • Publication number: 20220101453
    Abstract: A method of creating a recipe for a chemical composition, includes: receiving a property input from a user including at least one target physical property for a polymeric product to be produced from the chemical composition; receiving an initial chemical component for inclusion in the recipe; determining whether inclusion of the one or more initial chemical components in the recipe would produce the polymeric product having the at least one target physical property; generating, an advisory component recommendation comprising one or more additional or alternative chemical components for inclusion in the recipe; and modifying the recipe to include the one or more additional or alternative chemical components. A system and a computer program product for creating a recipe for a chemical composition are also disclosed.

  • Publication number: 20210374295
    Abstract: Disclosed are methods and interfaces for depicting a plurality of properties of a material, such as a haptic coating. In some aspects, gauges each expressing a property of the material may be displayed. Each property that collectively may describe the material may be defined along a gradient each of two opposing characteristics. Each of the physical properties may have an interrelationship with one or more of the other physical properties, such that when a particular value or quantity of one physical property is chosen, the other physical properties are constrained to a certain degree. The example gauges disclosed herein provide an interface that allows a user to easily understand these constraints and also allows for user friendly and intuitive manipulation of desired physical properties.

  • Publication number: 20210233618
    Abstract: A system, method, and computer program product for predicting a polymer. A method may include determining one or more prediction scores for a target polymer based on at least one descriptor of the target polymer from at least three descriptor groups, wherein the one or more prediction scores include a prediction of one or more physical properties for the target polymer. A method may include determining one or more prediction scores for a target polymer based on at least one desired physical property of the target polymer, wherein the one or more prediction scores include a prediction of one or more raw materials of the target polymer.

  • Publication number: 20210097211
    Abstract: Disclosed are methods of producing a graphical depiction of a predicted value of a property of a material. In accordance with the method, a processing unit generates a plot defining a geometric shape and comprising a plurality of points arranged in a matrix, each of the points defining a value for at least two variables and a predicted value of a property of the material. A visual representation of the predicted value of the property of the material for at least some of the plurality of points in a range of indicia is displayed on an output device. The range of indicia represents a range of predicted values of the property. A pointer on the visual representation is displayed on the output device.
