  • Publication number: 20250109959
    Abstract: Example embodiments described herein therefore relate to an AR guidance system to perform operations that include: detecting a client device at a location within a geo-fenced area, wherein the geo-fenced area may include within it, a destination of interest; determining a route to the destination of interest from the location of the client device within the geo-fenced area; causing display of a presentation of an environment within an AR interface at the client device; detecting a display of real-world signage within the presentation of the environment; generating a media item in response to the detecting the display of the signage within the presentation of the environment, wherein the media item is based on the route to the destination of interest; and causing display of the media item within the AR interface based on the position of the signage within the presentation of the environment.

  • Publication number: 20250105557
    Abstract: A connector housing assembly includes a first housing having a first flange installed on a first installation panel, the first flange has a first mounting hole, a first support member installed in the first mounting hole and having a first through-hole that extends along an axial direction of the first mounting hole, a first elastic ring fitted on the first support member and radially compressed between the first support member and an inner circumferential surface of the first mounting hole, and a first connecting member passing through the first through-hole and connectable to the first installation panel. There is a first radial gap between the first support member and the inner circumferential surface of the first mounting hole when the first housing is installed on the first installation panel, allowing the first housing to float radially relative to the first connecting member.

  • Publication number: 20250095203
    Abstract: Method for creating marker-based shared augmented reality (AR) session starts with initializing a shared AR session by a first device and by a second device. The first device displays on a display a marker. The second device detects the marker using a camera included in the second device and captures an image of the marker using the camera. The second device determines a transformation between the first device and the second device using the image of the marker. A common coordinate frame is then determined using the transformation, the shared AR session is generated using the common coordinate frame, and the shared AR session is caused to be displayed by the first device and by the second device. Other embodiments are described herein.

  • Patent number: 12213676
    Abstract: Neurovascular flow diverter and delivery systems, and methods of using the same are described herein. The systems can include a customizing member including an introducer sheath, a catheter, a deployable flow diverter that can be contained in the introducer sheath or in the catheter, a core wire, and one or several deployment features coupled to the core wire and engaging the flow diverter. The customizing member includes a tubing extending along and around a distal portion of the introducer sheath. This tubing is cuttable and contains a distal end of the flow diverter. The length of the flow diverter can be customized by cutting through the tubing and the therein contained flow diverter.
