Patent number: 12236523Abstract: Methods and systems for real-time visualization of building structures are disclosed. A computing system may calculate physical illumination characteristics for each of a plurality of predefined virtual external building-surface elements layered in simulation at specified surface locations of a virtual three-dimensional (3D) model of a building structure, wherein the virtual 3D model is constructed based on data descriptive of the building structure. Each of the plurality of predefined virtual external building-surface elements may be associated with its calculated illumination characteristics in a database. A spatially-manipulable rendered image of the building structure may displayed on an interactive display in real-time based on the virtual 3D model. On the interactive display device, one or more of the plurality of the predefined virtual external building-surface elements may be rendered in real-time at respectively specified locations on the rendered image.Type: GrantFiled: July 18, 2023Date of Patent: February 25, 2025Assignee: CERTAINTEED LLCInventors: Brice Dubost, Sizhu You, Rachel Z.

Patent number: 12226846Abstract: Systems and methods are disclosed that include an operation chamber, a plasma generator having at least one plasma head disposed within the operation chamber and in proximity to a profile formed by cutting a piece of tubing, and a mechanical motion module. The plasma generator generates a plasma treatment and applies the plasma treatment via the at least one plasma head to the profile to activate material on an end surface of the profile, within a lumen of the profile, or a combination thereof. Once the material of the profile is activated by the plasma treatment, the mechanical motion module manipulates the profile to close the lumen of the profile to aseptically seal the profile.Type: GrantFiled: February 23, 2021Date of Patent: February 18, 2025Assignee: SAINT-GOBAIN PERFORMANCE PLASTICS CORPORATIONInventors: Jianfeng Zhang, Rachel Z.

Patent number: 12229976Abstract: The present disclosure relates generally to evaluating the surfaces of a building. The present disclosure relates more particularly to a method of characterizing a surface texture of a building surface. The method includes illuminating a first area of the building surface from a single direction and capturing an image of the first area using a camera while the first area is illuminated. The first image includes a first group of digital pixel values. The method further includes calculating a first set of values that characterize a first surface texture of the first area based on a first group of digital pixel values of the image, and comparing the first set of values to a second set of values that characterize a second surface texture, so as to produce a comparator value.Type: GrantFiled: June 26, 2023Date of Patent: February 18, 2025Assignee: CertainTeed Gypsum, Inc.Inventors: Rachel Z.
