A heavy-duty automatic door using a linear bearing track

The present invention relates to the technical field of axially movable doors and windows, and specifically to a heavy-duty automatic door using a linear bearing track. The automatic door comprises a heavy-duty door, a moving mechanism, a supporting mechanism and an adjusting mechanism. An operator first starts the moving mechanism to move the heavy-duty door, and then uses rolling and replacement of rolling columns in the supporting mechanism to achieve rapid movement of the heavy-duty door. When it is necessary to stop, the adjusting mechanism is used to change the center of gravity of the heavy-duty door to achieve rapid stagnation. The device has a simple structure, effectively solves the inertia problem of rapid movement of heavy-duty doors using linear bearings and stagnation after movement, avoids damage to the mobile equipment, has good practicality and economy, and is beneficial to the promotion and use of the equipment.

Doors for artificial reality universe traversal

Aspects of the present disclosure are directed to creating virtual doors within artificial reality (XR) universes for traversal within that XR universe and between other XR universes. Users can create virtual doors that control access to their privately owned property (e.g., world, parcel, house, etc.) in an XR universe. For example, an owner of a virtual door can manually lock the door to prevent any user from entering their property through the virtual door. As another example, an owner of a virtual door can configure door permissions and / or privacy settings that serve as heuristics by which a door access control manager determines whether to authorize a particular user, XR world, and / or XR universe to access. The XR universe traversal system can control an execution environment to smoothly transition between different applications, thereby enabling a user to traverse between different XR universes without having to leave the XR environment.
