Abstract: Methods and systems for allowing for incremental updates to remote localized copies of disk images (e.g., virtual machine images) are described. In some implementations, the disk images are block-based. The incremental updates may be done in a bi-directional manner across different platforms such that an update to any platform may be prepared for any of the other platforms. Preparation of updates between platforms may be accomplished through one or more of combining disk images, differencing disk images, snapshotting disk images, and/or versioning disk images.

Abstract: The present invention provides methods and systems for transporting a virtual workspace from one computer to another, without installing hardware elements on the second computer. The virtual workspace may be embodied as a set of virtual disk images that facilitate the transportation of the workspace to another computer without installation of hardware elements.

Abstract: The present invention provides methods and systems for virtualization of workspaces in a computer system. The computer system may include an operating system that may abstract the computer's hardware and other applications. Further, the operating system may contain and isolate operating system services from each other and applications and may facilitate virtualized execution of one or more applications. In addition, the virtualization of workspace may contain and isolate user data from the hardware, the operating system and the applications, and may use a server to provide remote access to the virtualized workspace from a client device.

Abstract: The present invention provides methods and systems for transporting a virtual workspace from one computer to another, without installing an operating system on the second computer. The virtual workspace may be embodied as a set of virtual disk images that facilitate the transportation of the workspace to another computer for operating the workspace without necessitating the installation of an operating system.

Abstract: The present invention provides methods and systems for updating one or more virtualized workspaces. The one or more virtualized workspaces may be facilitated by cloning a master root disk image, and then applying temporary personalization to the master root disk image clone. The master root image clone may then be published to one or more of the users by omitting one or more portions of the personalization. Furthermore, re-personalization of a user's copy of the published master root disk image clone may be provided for use on the local computer of the user; re-personalization of a user's copy may be based at least in part on the clone.

Abstract: Embodiments deliver an operating system and software applications to a personal computer. The operating system and software applications may be managed and configured at a central location prior to delivery. Data that is created or modified on the personal computer may, from time to time, be stored at the central location. When a user switches from one personal computer to another, any and all of the data may be transferred from the central location to the user's current computer. Additionally, the user's current computer may receive suitable versions of the operating system and applications from the central location. In any case, the operating system and software applications may run with a domain of execution that is provided by a hypervisor. Thus, the operating system and software applications may operate within a virtualized machine, perhaps alongside and in isolation from other operating systems and software applications.

Abstract: A process and apparatus for LPCVD of thin metallic films is disclosed. The apparatus includes a U-shaped injection tube through which high molecular weight reactants are injected into a reaction chamber. The input and output ends of the U-shaped tube are coupled to a removeable feedthrough plate which, in turn, is coupled to the end cap which seals one end of the reaction chamber. A deposition surface is placed in the chamber through a second end cap at the opposite end of the chamber. The output end of the U-shaped injection tube is coupled to a vacuum pump and the high molecular weight reactant is drawn through the injection tube and dispersed in the reaction chamber through a plurality of holes in the input side of the injection tube.

Abstract: Reaction vessels, furnace tubes, heating and cooling enclosures frequently have parts such as access ports, inlet tubes, inspection windows, etc. made of thermally transparent materials such as plastic, glass, quartz, oxides, nitrides and sulfides. When these parts extend outside the hot zone, they can act as "light pipes" carrying appreciable amounts of thermal radiation which can damage thermally sensitive gaskets or other materials used to secure external couplings or end closure flanges to these parts. Thermal radiation induced gasket damage is a frequent cause of stuck flanges and couplings. This problem is avoided by inserting a thermal radiation scattering region in the thermally transparent material between the hot zone and the end closure or gaskets. The thermal radiation is scattered and dispersed, so that the end zones receive less radiation and remain cooler. Milky quartz is a suitable scattering material for use with quartz furnace tubes or bell jars.

Abstract: A ball valve particularly suited for use in the handling of highly corrosive fluids characterized by a valve housing formed of communicating segments of quartz tubing, a pair of communicating sockets disposed in coaxial alignment with selected segments of tubing for establishing a pair of inlet ports communicating with a common outlet port, a ball formed of quartz material supported for displacement between the sockets and configured to be received alternately thereby, and a valve actuator including a rod attached to the ball for selectively displacing the ball relative to each of the sockets for controlling fluid flow through the inlet ports.
