  • Patent number: 11773435
    Abstract: A method for capturing ancient DNA of a wooden cultural relic, sequentially includes the following steps: sampling, removing exogenous DNA contamination on the inner part and the outer surface of a sample, and effectively obtaining the ancient DNA of the wooden cultural relic through vacuum freeze-drying dehydration, sample grinding, rinsing, cell lysis, DNA genome enrichment and hybridization and capturing. The method focuses on precise capture of the ancient DNA of the wood cells of the wood cultural relic, not only breaks through the problem that effective acquisition of the DNA of the wood cultural relic is difficult to realize by a conventional wood DNA extraction method, but also provides possibility for analysis and utilization of the ancient DNA with typical characteristics of serious exogenous contamination, low DNA content, high degradation, extensive damage and the like.

  • Patent number: 11010889
    Abstract: A device for measuring wear is disclosed. The device may receive images associated with a component, and may receive a three-dimensional (3D) model of the component. The device may generate an image point cloud based on the images, and may generate a model point cloud based on the 3D model of the component. The device may perform a first alignment of the image point cloud and the model point cloud to generate first-aligned point clouds, and may perform a second alignment of the first-aligned point clouds to generate second-aligned point clouds. The device may generate 3D mask regions based on the second-aligned point clouds, and may project the 3D mask regions on the images. The device may process the 3D mask regions, projected on the images, to determine reference points in the images, and may determine an amount of wear associated with the component based on the reference points.
