Abstract: Disclosed is A dynamic insulation system that includes a base, one or more slats, a cap, and an inflator. The base is attached to one end of the one or more slats. The cap is attached to the second end of the one or more slats.

Abstract: A plurality of air flow velocity vectors are generated at a plurality of predefined angles of rotation of a digital model of a rotating tire. Individual ones of the vectors are associated with a corresponding one of a plurality of first cells of a first mesh with a tread of the rotating tire or a corresponding one of a plurality of second cells of a second mesh in a volume around the rotating tire. Air flow velocity vectors are converted into corresponding ones of a plurality of Lighthill stress tensors. An acoustic pressure is generated at a plurality of points on a surface of the volume for each of the predefined angles of rotation of the rotating tire based on the Lighthill stress tensors. An estimate of a magnitude of sound generated by the rotating tire is determined from the acoustic pressure at a respective one of the points.

Abstract: A large area sintering platform, system, and methodology. The system includes a convection oven with a projection window disposed within a top surface of the oven. A platform is disposed within the oven below the window at a spaced distance away from the window. A powder is positioned on top of the platform, with a thermocouple positioned within the powder on the platform. A high intensity projector moves in sync with the platform, and uses low intensities and long exposure times to project an image through the window onto the powder and sinter the powder to fabricate the desired model layer by layer.

Abstract: Disclosed is a method for observing and controlling powder melting in a 3-dimensional printer receiving input from a computing device. The 3-dimensional printer initiates the melting of powder on a powder bed. The 3-dimensional printer receives real-time feedback based on information from one or more optical sensors. The 3-dimensional printer adjusts output based on feedback from the optical sensors, and the 3-dimensional printer executes the melting of the powder on the powder bed based on the adjustments.

Abstract: The disclosed subject matter relates to method for increasing the molecular weight of a polymer material during an additive manufacturing process. The method can comprise disposing a first layer of the polymer material at a target surface; exposing the first layer of the polymer material to an energy source for a sufficient period of time to sinter or melt and undergo a condensation reaction at least at a portion of the polymer material; controlling the condensation reaction to allow a desired increased number average molecular weight of the polymer material; and repeating the method steps to form an object in a layerwise fashion. Controlling the condensation reaction can comprise controlling and/or adjusting an energy 10 source-related parameter, a polymer-related parameter, a temperature related parameter, a vacuum related parameter, a process duration, a processing gas, an air flow volume and/or speed, or a combination thereof.
