  • Publication number: 20250098731
    Abstract: An exemplary smoking article includes a smoking rod filled with a combination including tobacco filler material and cellulose filler material. The tobacco filler material and cellulose filler material can be arranged such that the constituent material particles are generally distributed throughout the smoking rod, the tobacco filler material at least partially surrounds the cellulose filler material along a length of the smoking rod, and/or the cellulose filler material particles have a higher concentration along a central axis of the smoking rod than the tobacco filler material particles.

  • Patent number: 12118698
    Abstract: Provided are a method for inpainting a highlight region of a vegetation image captured by an unmanned aerial vehicle, a device, a medium, and a product. The method includes: acquiring an image to be inpainted, and a historic image; inputting the image to be inpainted to a trained target detection network to obtain a waterbody highlight region image block; determining a template image block of the image to be inpainted based on the waterbody highlight region image block; cropping the historical image to obtain a plurality of candidate image blocks of the image to be inpainted; determining similarity between each candidate image block and the template image block by using a deep learning image coarse matching method; and screening candidate image blocks with the similarity greater than a predetermined threshold, and determining an optimal candidate image block in the candidate image blocks by using a pixel-by-pixel matching method.

  • Publication number: 20190174814
    Abstract: An example smoking article includes a smoking rod filled with a filler material. The filler material includes tobacco material and non-tobacco leaf material, and the filler material is distributed along a length of the smoking rod. In certain examples the tobacco material, non-tobacco leaf material, or both may be treated with one or more additives, and in other examples the filler material may not include additives. The smoking article can be formed as a cigarette, cigarillo, or cigar.

  • Patent number: 9915779
    Abstract: The low magnetic sensitivity PM-PCF based on mechanical buffer is obtained by adding buffer structures in the cladding layer of the photonic crystal fiber. In the center of the fiber, the core region contains at least 3 layers of air-holes, enclosed by the cladding layer. The buffer structures are placed in the cladding layer. These buffer structures are formed by replacing silica of any shape by air, and are symmetrically located in X-axis and Y-axis directions to achieve mechanical isotropy. The buffer structures improve the fiber's performance in fiber coiling and stress conditions. Therefore, the fiber optic gyroscope using the PM-PCF can do without a magnetic shield, thus greatly reducing the weight of the fiber optic gyroscope and extending the scope of its application. Compared with the conventional commercial PCF, the PM-PCF provides the fiber optic gyroscope with lower temperature sensitivity and improved accuracy.
