  • Publication number: 20230334929
    Abstract: Systems and methods are provided to generate an access code specific to a user of an online marketplace to use to enter a first accommodation during a first reservation time frame and a second accommodation during a second reservation time frame and to send the access code specific to the user to a computing device at the first accommodation and a computing device at the second accommodation to use to enter the first accommodation during the first reservation time period and the second accommodation during the second reservation time period. The access code is automatically removed from the computing device at the first accommodation and the computing device at the second accommodation at the end of the first reservation time period and at the end of the second reservation time period, respectively.

  • Patent number: 10930057
    Abstract: Systems and methods are provided for accessing a three-dimensional (3D) image comprising a 3D mesh comprising a plurality of vertices and each vertex of the plurality of vertices having respective 3D coordinates within a space of the 3D mesh. The systems and methods further provide for generating a subset of the plurality of vertices comprising vertices that are within a specified height range and have a specified orientation. The systems and methods further provide for generating a two-dimensional (2D) grid corresponding to the 3D mesh, applying the subset of the plurality of vertices to the 2D grid, and rendering a 2D image of the space comprising an outer border corresponding to the size and shape of the 2D grid and indications of walls within the space based on the applied subset of the plurality of vertices.
