摘要： Extensions to operating systems or software applications can be hosted in virtual environments to fault isolate the extension. A generic proxy extension invoked by a host process can coordinate the invocation of an appropriate extension in a virtual process that can provide the same support APIs as the host process. Furthermore, a user mode context can be provided to the extension in the virtual process through memory copying or page table modifications. In addition, the virtual process, especially a virtual operating system process running on a virtual machine, can be efficiently started by cloning a coherent state. A coherent state can be created when a virtual machine starts up, or when the computing device starts up and the appropriate parameters are observed and saved. Alternatively, the operating system can create a coherent state by believing there is an additional CPU during the boot process.

摘要： Extensions to operating systems or software applications can be hosted in virtual environments to fault isolate the extension. The virtual environment in which extensions designed to control hardware devices can safely execute can be efficiently created during an initial startup sequence of a host environment by indicating to the host environment that a second processing unit is present in the computing system allowing the host environment to create a coherent state. A virtual process, especially a virtual operating system process running on a virtual machine, can be efficiently started by the created coherent state. A coherent state can be created when an operating system starts up and the appropriate parameters are observed and saved. Alternatively, an operating system of the host environment can create the coherent state by receiving indication of the second processing unit during the boot process.

摘要： A lifting and shaping system for a bra is disclosed. The system uses lift platforms shaped to fit into the cups of the bra and formed from thin material such as plastic. The lift platforms are attached to the bra toward the center of the bra. Connectors having one end attached to the lift platform and the other end attached to a slide on the shoulder strap adjust the lift of the lift platform when the slide is moved. Flexible shaping members distribute the lift of the lift platforms and maintain the natural shape of the breasts as they are lifted. Smoothing shields ease the movement of the lift platforms and connectors within the cloth confines of the breast cups. The flexible shaping members may also perform some of the functions of a smoothing shield.

摘要： A system is provided for reading and writing sectors which may be realized as either a disk device to the local operating system, or as a virtual disk device to a virtual machine. A user's computing environment is stored in the network in the form of a disk image, which may be a virtual disk image, for example. The virtual disk is realized on host computers through host-resident virtual machine monitors such as MICROSOFT VIRTUAL PC®. Portable memory devices, such as flash devices, buffer virtual disk writes and cache reads, greatly reducing the performance degradation associated with remote disk access. The cache is mobile so that it can be travel with the user. The flash device remembers commonly used virtual disk content fingerprints so that the host machine's local disk can be used to satisfy many common disk reads when ubiquitous static content is involved. Standard, frequently used software images might be distributed in advance to host machines. Flash disk contents are trickled back into the networked parent disk image in order to provide an automatic backup facility, adding the benefit of ensuring that the flash drive doesn't overflow.

摘要： Described herein is an implementation of an inter-process communications technology. One or more implementations, described herein, facilitate creation of a bi-directional message conduit having exactly two endpoints. A first endpoint is owned by a first software process and a second endpoint is owned by a second software process. One or more implementations, described herein, maintain the bi-directional message conduit for passing multiple messages via the bi-directional message conduit from the first process to the second process, according to established rules that can be checked.

摘要： In a computer implemented method, a client computer connected to a public network such as the Internet makes a request for an intranet resource to a tunnel of a firewall isolating the intranet from the Internet. The request is made in a public message. The tunnel sends a message to the client computer to redirect to a proxy server of the tunnel. The client computer send a token and the request for the resource the proxy server. If the token is valid, the request is forwarded to the intranet, otherwise, the user of the client computer must first be authenticated.
