Abstract: Systems and methods for connecting users in an extended reality setting are provided. One embodiment includes creating a private group for an extended reality session, registering a facility user for the private group and a first user identifier for the facility user, and registering a first device to link to the facility user. Some embodiments include registering a first user for the private group and a second user identifier for the first user, registering a second device to link to the first user, and receiving a request from a device of a possible user to join the session. Still some embodiments include retrieving a security certificate from the device, determining whether the security certificate corresponds, and in response to determining that the security certificate corresponds granting access to the possible user to the extended reality session. In response to determining that the security certificate does not correspond, denying access.

Abstract: Very high strength single phase stainless steel coating has been prepared by magnetron sputtering onto a substrate. The coating has a unique microstructure of nanometer spaced twins that are parallel to each other and to the substrate surface. For cases where the coating and substrate do not bind strongly, the coating can be peeled off to provide foil.
