  • Publication number: 20240420409
    Abstract: A system and method for translating a 3D visualization to a 2D visualization is provided. Data for a 3D visualization is received and includes layers of voxels that are processed to determine a type of terrain and color associated with the terrain type. Each voxel in a base layer of the 3D visualization is transformed into a tile of pixels for a 2D visualization. The color associated with the layers is assigned to the tiles by identifying, for each such layer, a marker for each voxel in that layer that indicates a presence or absence of the terrain type for that layer and applying the color associated with the layer to at least a portion of the tiles based on the markers. When multiple colors are applied to one of the tiles, the color associated with the layer furthest from the base layer is selected. The 2D visualization is output.

  • Publication number: 20240339560
    Abstract: Data representations are formed of a target substrate and a plurality of donor coupons that are incompletely filled with functional chips. The data representations are abstracted into a current state description of the target substrate and the donor coupons and input into a machine learning model that has been trained on previous mass transfer sequences. An optimal output of the machine learning model defines at least a selected one or more of the donor coupons and corresponding functional chips of the selected one or more of the donor coupons used to fill the vacancies. A parallel transfer of the corresponding functional chips is performed to fill the vacancies on the target substrate using the selected one or more of the donor coupons.

  • Patent number: 12079922
    Abstract: A system and method for translating a 2D image to a 3D image is provided. A 2D image having pixels grouped into tiles is obtained. Contour lines associated with an altitude value are located on the 2D image. The altitude values are determined. Each tile in the 2D image is represented using at least one voxel. A height map of the voxels is generated based on the contour lines and altitude values as a base layer for a 3D image. A terrain type of each of the voxels of the 3D image is determined and objects are placed in the 3D image. The 3D image is output.

  • Patent number: 12068430
    Abstract: A method utilizes a target substrate has an array of chips on a carrier with a plurality of vacancies and a plurality of donor coupons are incompletely filled with functional chips. A bounding box is defined that encompasses the vacancies on the target substrate. Outcomes are simulated by overlapping a representation of the bounding box over a representation of each of a plurality of donor coupons at a plurality of translational offsets on a substrate plane to determine matches. An optimal one of the outcomes is found at a selected one or more of the donor coupons corresponding one or more offsets. A parallel transfer of the matching functional chips fills the vacancies on the target substrate using the one or more selected donor coupons and corresponding one or more offsets.

  • Publication number: 20240169700
    Abstract: A system for generating a labelled image data set for use in object detection training includes a three-dimensional scan of an object and its environment in a coordinate space generated using a set of images taken by a user device. The three-dimensional scan has an annotation of the object in the coordinate space. Each image in the set of images has position information of the user device in the coordinate space. A computing system is adapted to annotate the set of images by projecting the annotation of the object onto each image using the position information. The computing system is adapted to generate a labelled image set for teaching object detection using the annotated set of images.
