Abstract: 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.

Abstract: Aspects of the present disclosure are directed to systems for capturing, recording, and playing back steps for building objects and structures in an artificial reality (XR) world. A teacher or creator can initiate a capture context within a build mode of an XR application, during which steps (and potentially other metadata) of a building process are recorded and stored. A XR world building engine can generate an interactive replay of the recorded building process that allows another user to view the building process within an XR environment at the user's preferred pace and/or from different perspectives. In some implementations, the XR world building engine can generate a replay of the teacher's or creator's avatar performing the building process, such that the user can view the building process from a third person perspective and perform the same steps to learn how to build objects and structures in an XR world.

Abstract: Implementations can provide a virtual separate space with respect to a virtual venue hosting a virtual reality (VR) experience, such as a concert, a sports game, a meeting, etc., e.g., to replicate the feeling of a side conversation to discuss the VR experience. Some implementations can create a more intimate experience for users viewing a VR experience by providing a quiet, curated space that can be customized, e.g., by changing the look of users' avatars and their virtual environment, without their interactions being observed by others viewing the VR experience at the virtual venue. The virtual separate space can include a moderated version of the VR experience, such as a smaller version of the VR experience with the sounds of the VR experience muffled. Thus, users within the virtual separate space can step away from the VR experience to enter a more controlled environment, while still enjoying the VR experience.

Abstract: Ultraremovable adhesive is applied to a paper sheet to form therewith a liner sheet, and the liner sheet is laminated to a cardstock sheet to form a laminate cardstock. The cardstock sheet is then die cut therethrough, but not through the liner sheet, to form cardstock cut lines that define at least in part perimeters of business cards (or other printable media). The outer face of the liner sheet is then die cut therethrough, but not through the cardstock sheet, to form liner sheet strips on a back side of the cardstock sheet. Some of the strips define cover strips covering some of the cardstock cut lines, and others of the strips define waste strips. The waste strips are then matrix removed from the back of the cardstock sheet. According to a preferred (dry laminate) embodiment the only liner sheet die cut is parallel to the leading edge of the sheet and forms a narrow leading edge liner strip which is removed.

Abstract: An interface card for a network or other communication channel, with limited intelligence, is implemented using a relatively slower, and lower cost embedded processor, supported by dedicated hardware logic for the purposes of intercepting certain packets being received via the network or communication channel. The interface comprises the first port on which incoming data is received at the data transfer rate of the network, a buffer coupled to the port that stores received packets, and a second port coupled with the buffer through which transfer of packets to the host is executed. Packet filters are coupled to the first port which identifies packets being stored in the buffer that have one of the plurality of variant formats. A processor is coupled with the buffer as well, and is responsive to the packet filter to process identified packets in the buffer.

Abstract: Methods and products are disclosed in the manufacture of liner-carried "dry" tags or labels, and the manufacture of liner-carried presure-sensitive coated middle liners on which dry tags or labels are "piggybacked," and the manufacture of liner-carried coupons printable on one side. These methods and products utilize a carry-release component comprising a paper or film layer and a thermoplastic film cast or extruded onto the paper or film layer so as to be firmly but temporarily anchored thereto.
