Abstract: Methods, computer-readable media, and systems provide cross-experience communication in a virtual environment, including receiving a request from a requesting user in a first virtual experience to form a communication session with a receiving user in a second virtual experience; verifying a permission for the requesting user; in response to successfully verifying the permission: reserving a platform instance to coordinate forming the communication session; notifying the receiving user about the communication session; receiving a notification from the receiving user accepting the communication session; notifying the requesting user that the communication session was accepted; starting a designated data model to host the communication session; and forming the communication session between the requesting user and the receiving user using the designated data model and the platform instance, the designated data model having access to a subset of information in a data model associated with the receiving user relate

Abstract: A waste-reducing pumping system and method for delivering a liquid to a patient according to a predetermined therapy protocol is characterized by a stored flush mode routine executable by a processor after an end-of-therapy stoppage of a pumping mechanism, whereby the pumping mechanism is operated to deliver residual liquid remaining in downstream tubing of an administration set to the patient to prevent the residual liquid from being wasted or manually administered at an unsafe rate.

Abstract: A system, computer-readable storage medium storing at least one program, and a computer-implemented method to present a location-based leaderboard is provided. A request to play a game against a second player is received, the request being received from a first client device of a first player and including a location of the first client device. A pre-defined location associated with the location of the first client device is determined. A game instance of the game is generated in response to the request. An outcome associated with the game is determined. The outcome of the game instance is published including publishing the outcome based on the pre-defined location.

Abstract: A percutaneous dilation apparatus is shown. The apparatus is useful for forming and enlarging percutaneous penetrations to a variety of target locations within a patient's body for multiple purposes. The apparatus includes an at least one dilator segment, a dilator probe, and a mechanism for moving each dilator segment along the dilator probe so as to place it within the penetration thereby dilating the penetration.

Abstract: Disclosed is an attachment to a construction vehicle which facilitates the transport and pouring of flowable materials such as concrete. The device contains a carrier bucket shaped substantially like an inverted cone, truncated on one side, with a pouring spout along a top edge. The device is quickly and conveniently attached to a front end loader or other suitable construction vehicle which is able to navigate to various pour sites where the material is to be distributed. The carrier bucket is tipped forward by the hydraulics of the construction vehicle and the concrete pours over the spout of the top edge, thereby providing a workable, manageable flow which can be accurately directed to specific areas as needed.

Abstract: A powder mixture for use in ceramic welding repair of a refractory material containing alumina includes refractory particles including alumina; at least 5% by weight of a metallic combustible which is at least 30% aluminum; and from 3 to 10% by weight of an additive which is at least one material selected from the group consisting of aluminum fluoride, barium sulfate, cerium oxide, and calcium fluoride. A process for repairing a refractory material which contains alumina includes providing the above powder mixture; and projecting the powder mixture against a surface of the refractory material in the presence of gaseous oxygen so that the combustible particles and the gaseous oxygen react and release the heat of reaction against the surface and form a coherent refractory mass.
