Abstract: Disclosed are a video conference realization method, system, and a computer storage medium. The method includes: acquiring a conference hall video collected by each user who attends a conference in each conference hall and a portrait video of each user who attends the conference in each conference hall; synthesizing, according to a pre-set synthesis scheme, the portrait video of each user who attends the conference in each conference hall and a conference hall video collected by a pre-set user who attends the conference so as to form a virtual video to be displayed; and sending virtual videos respectively to a displaying means of each user who attends the conference.

Abstract: A novel method and system for using certain tin compounds as dopant sources for ion implantation are provided. A suitable tin-containing dopant source material is selected based on certain attributes. Some of these attributes include stability at room temperature; sufficient vapor pressure to be delivered from its source supply to an ion chamber and, the ability to produce a suitable beam current for ion implantation to achieve the required implant Sn dosage.

Abstract: A novel method and system for using certain tin compounds as dopant sources for ion implantation are provided. A suitable tin-containing dopant source material is selected based on one or more certain attributes. Some of these attributes include stability at room temperature; sufficient vapor pressure to be delivered from its source supply to an ion chamber and, the ability to produce a suitable beam current for ion implantation to achieve the required implant Sn dosage. The dopant source is preferably delivered from a source supply that actuates under sub atmospheric conditions to enhance the safety and reliability during operation.

Abstract: Disclosed are articles useful as the body of a container for containing gas under pressure, and containers which comprise the articles to which are affixed valves to control the flow of gas out of the container, wherein the articles comprise a hollow container body, having an external surface and having an opening through which gas can enter or leave the interior of the hollow container body; optionally but preferably a layer of fiber-reinforced polymer around the exterior of the container body, and an external layer of elastomer around and sealed to the external surface of the layer of fiber-reinforced polymer if present or else to the cylinder body.

Abstract: A nitrous oxide charging system to make whipped cream by charging food-grade N2O gas into a whipped cream dispenser that contains a certain amount of heavy cream is provided. The charging system includes a compressed gas container with liquefied nitrous oxide and a delivery unit that comprises an on/off valve; a pressure regulator configured to operate at a controlled outlet pressure; and a flexible tubing connecting with a dispenser. The charging system also includes a means to select the optimum delivery pressure based on the amount of heavy cream, and the accepted tolerance of the delivery pressure. An optional dispenser kit is also provide that can include a dip tube and/or oscillating arm-like structures as part of a dispenser kit operably connected to the dispenser to promote mixing and chemical solvation.
