  • Publication number: 20230296402
    Abstract: Methods, systems, and products for generating an updated map for use with an autonomous vehicle driving operation or a simulation thereof may include obtaining first map data associated with a first map of a geographic location including a roadway, and the first map data may include at least one first lane segment. Second map data associated with a second map of the geographic location may be obtained, and the second map data may include at least one second lane segment. A plurality of non-overlapping areas may be determined based on the first lane segment(s) and the second lane segment(s). A first non-overlapping and/or a first warp point within the first non-overlapping area may be selected. The first lane segment(s) may be warped around the first warp point to increase a total overlapping area based on the based on the second lane segment(s) and the first lane segment(s) after warping.

  • Publication number: 20210322242
    Abstract: Respiratory isolation systems and devices for facilitating delivery of respiratory treatments to a patient. The device incudes a housing, a filtration unit, and at least one access port. The housing includes a front panel, a rear panel, one or more side panels, and a top panel that combine to define a chamber. The housing defines an open base that is open to the chamber, and the front panel defines an opening to the chamber. The filtration unit is mounted to the housing and includes a filter in fluid communication with the chamber. The access port is formed through one of the panels and permits user access to the chamber from an exterior of the housing. When connected to an airflow source as part of a respiratory isolation system, negative or positive pressure can continuously be provided to a patient within the chamber.
