Abstract: A computer implemented platform agnostic system for spatial synchronization of physical and virtual locations that provide user experiences to be created or where local and remote users can interact. The system having a central server, at least one XR headset connected to the central server, and instructions executable on the server and XR headset for mapping a physical location into a digital twin or shared XR virtual environment; mapping a shared XR virtual environment; interacting with the one or more than one shared XR virtual environment; tracking one or more than one user accurately in both the physical and the one or more than one XR virtual environment without needing expensive equipment external to the one or more than one users' XR headset integrated display system, wherein the executable instructions are platform agnostic; and controlling the XR virtual environment, assets, content, theme, script/narrative, and interactions in real-time.

Abstract: A tooth cleaning device comprising a handle, and a pad coupled to the handle, wherein the pad has a front face, a back face and a plurality of side walls. There are a plurality of different areas disposed on the front face of the pad comprising a first area comprising a first set of protrusions, in a substantially semi-spherical shape, and a second area comprising a second set of protrusions in a substantially conical shape. There is also a third area of protrusions formed as a substantially conical shape, and a fourth area of protrusions formed as a substantially semi-spherical shape. The device can be formed as a pad which collapses voluntarily under pressure. The pad can be made from any suitable material such as any type of rubber or plastic.

Abstract: A process for making an untempered martensite-free welded steel tubular is disclosed. The process includes rapid quenching of the steel tubular without formation of untempered martensite, at rates up to about 1600° F./second. There is no post-weld seam annealing process required. Also a welded steel tubular made in accordance with the disclosed process is described.

Abstract: An oral cleaning device having two portions, wherein the first portion is to be handled by the user, and the second portion, having a terry cloth sleeve affixed thereto, is inserted into the mouth for cleaning the vestibule and for removing plaque from teeth therein.

Abstract: A device for cleaning the vestibule of the mouth. The device includes a rounded tapered end having a bend or curve with respect to a longitudinal axis of the device. The rounded end may be rotatable with respect to a handle portion of the device. The device may be used alone or in combination with a fabric sleeve to sweep matter from the vestibule.
