  • Publication number: 20240137929
    Abstract: This application provides a sidelink feedback information transmission method and a communication apparatus. The method includes: A first terminal sends first indication information to a second terminal, where the first indication information indicates that first channel occupancy time includes a first physical sidelink feedback channel PSFCH resource; and the first terminal receives, on the first PSFCH resource, feedback information from the second terminal. In this application, the second terminal sends the feedback information by using a resource contended by the first terminal. Compared with a solution in which the second terminal contends for a resource to send the feedback information, this solution in this application can reduce a possibility of a contention failure of the second terminal, and improve accuracy of data transmission.

  • Patent number: 11946128
    Abstract: A method for desensitizing a metal alloy such as an aluminum (Al) alloy is presented. The surface of the alloy is treated by controlled laser beam irradiation. The scanning laser beam heats the alloy to reach a relative low temperature between a solvus temperature and a soften/annealing temperature of the metal alloy to controllably reduce the degree of sensitization (DOS) of the metal alloy. The locally rapid heating and cooling effects produced by scanning the laser can improve the future sensitization resistance of the metal alloy, reduce the average desensitization temperature applied, and maintain the mechanical properties of Al alloy at the same time.

  • Patent number: 11945754
    Abstract: A method for forming a complex shape three-dimensional ceramic article by printing a first layer of a first material having a first fraction of first ceramic particles and a first fraction of a first polymeric ceramic precursor. A second layer is printed such that it is at least partially disposed on the first layer of a second material having a second fraction of second ceramic particles and a second fraction of a second polymeric ceramic precursor. A composite of the first layer and the second layer is heated at a temperature sufficient to decompose the first and second polymeric ceramic precursors and sinter the article. During the sintering process, the first and second layers with different fractions of ceramic particles undergo different degrees of shrinkage, resulting in a tuneable mismatch of the bilayer structure and accurately achieving a targeted geometry.
