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 or other software applications can have direct access to hardware from within a virtual machine environment. The physical addresses of hardware can be mapped into the process space of the virtual machine environment. Similarly, I/O ports can be allowed to pass through into the virtual environment. The virtual machine can detect an upcoming Direct Memory Access (DMA), and can provide the correct addresses for the DMA, while the necessary memory can be pinned. If the virtual machine is executing when a hardware interrupt arrives, it can emulate the interrupt line inside its process. Conversely, if the host operating system is executing, it can disable interrupts and track temporary interrupts, and subsequently transfer control to the virtual machine process, emulate the temporary interrupts and reenable interrupts. Alternatively, the host operating system can immediately transfer control, or it can execute the interrupt servicing routines in its own 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： Techniques enable range-based queries in searchable symmetric encryption (SSE) systems. A server device includes or provides access to a database that stores encrypted documents along with an encrypted index that maps bucketized terms (e.g., a term coupled with a value range associated with that term) to encrypted documents. Search is performed through a two-step process in which the client first sends a first search token to request the bucketization for a term, then sends one or more second search tokens each specifying a particular bucket in which to search for the term. In response to the second tokens, the server sends information corresponding to encrypted documents that satisfy the search. Embodiments further provide for incremental addition and deletion of particular values for a term, and rebucketization at the client when a rate of false positive search results exceeds a threshold.

摘要： In a reproduction environment, speakers are grouped in directional groups, wherein the directional groups overlap with respect to the associated speakers so that speakers are present which have a speaker parameter having different values for the first directional group and the second directional group. A controller for controlling a plurality of speakers has a provider for providing a source position of an audio source, wherein the source position is located between the first directional group position and the second directional group position. The apparatus further has a calculator for calculating a speaker signal for the at least one speaker, based on the first parameter value for the speaker parameter and based on the second parameter value for the speaker parameter.

摘要： In a wave field synthesis apparatus for driving an array of loudspeakers with drive signals, the loudspeakers being arranged at different defined positions, a drive signal for a loudspeaker being based on an audio signal associated with a virtual source having a virtual position with reference to the loudspeaker array and on the defined position of the loudspeaker, at first relevant loudspeakers of the loudspeaker array are determined on the basis of the position of the virtual source, a predefined listener position, and the defined positions of the loudspeakers, so that artifacts due to loudspeaker signals moving opposite to a direction from the virtual source to the predefined listener position are reduced. Downstream to means for calculating the drive signal components for the relevant loudspeakers and for a virtual source, there is means for providing the drive signal components for the relevant loudspeakers for the virtual source to the relevant loudspeakers, wherein no drive signals for the virtual source are provided to loudspeakers of the loudspeaker array not belonging to the relevant loudspeakers. With this, artifacts in an area of the audience room due to a generation wave field are suppressed, so that in this area only the useful wave field is heard in artifact-free manner.

摘要： An apparatus for generating, storing or editing an audio representation of an audio scene includes audio processing means for generating a plurality of speaker signals from a plurality of input channels as well as means for providing an object-oriented description of the audio scene, wherein the object-oriented description of the audio scene includes a plurality of audio objects, wherein an audio object is associated with an audio signal, a starting time instant and an end time instant. The apparatus for generating further distinguishes itself by mapping means for mapping the object-oriented description of the audio scene to the plurality of input channels, wherein an assignment of temporally overlapping audio objects to parallel input channels is performed by the mapping means, whereas temporally sequential audio objects are associated with the same channel. With this, an object-oriented representation is transferred into a channel-oriented representation, whereby on the object-oriented side the optimal representation of a scene may be used, whereas on channel-oriented side the channel-oriented concept users are used to may be maintained.
