One embodiment of the present invention provides a system that facilitates generating spatialized audio from non-three-dimensional aware applications. The system operates by intercepting parameters associated with audio use from an application. The system then obtains location information of a display window associated with the application within a three-dimensional display. Next, the system calculates an audio source location for the audio and positions the audio at the audio source location in a three-dimensional sound space, wherein the audio source location is associated with a location of the display window in the three-dimensional display.

A system and method for communicating 3D branch graph data and updates to branch graph data between clients and a display server in a 3D window system. A client locally creates a branch graph. When the client ready to make the branch graph live remote, it sends the branch graph to the display server using at least one batch protocol request. The display server builds a copy of the branch graph and attaches it to a centralized scene graph that it manages. The client may subsequently induce detachment of the branch graph from the scene graph. The client may buffer up changes to the local branch graph when its remote counterpart (in the display server) is not attached to the scene graph. The buffered changes may be sent to the display server using at least one batch protocol request when the client is again ready to make the branch graph live remote.

One embodiment of the present invention provides a system that uses a zooming effect to provide additional display space to manage applications. In one mode of operation, the system presents an image of a computer desktop to the user on a display device. When the system receives a request from a user to provide additional display space in a display device for application management purposes, the system decreases the size of the computer desktop in the display device to provide an extended display area. The system then facilitates application management by displaying items useful for application management in this extended display area. By providing the extended display area, the system allows the user to access such items easily and efficiently without losing the context of the computer desktop.

One embodiment of the present invention provides a system that automates context-compensated rendering of text in a graphical environment. First, the system receives a specification of the graphical environment that includes text to be rendered in the graphical environment. Next, the system determines the parameters of the local environment near the text. Then, the system dynamically renders text to compensate for those parameters, in order to display the text more clearly.

Disclosed is a system having a power input line. A power supply facility provides the system with a combined set of signals including a power signal and a status signal over the power input line.Additionally, disclosed is a system having at least two power input lines. Uninterruptible power supply facilities provide the system with combined sets of signals including a power signal and a status signal over the power input lines. Each combined set of signals includes a unique UPS identifier, which can be used to determine whether power sources for power input lines are unique.

Disclosed are methods and apparatus for managing resources. In general terms, a resource manager manages resource consumption of several resource entities which are each capable of consuming resources. The resource manager tracks the availability of such resources and determines whether a resource is critically short or reaches a particular usage level. When a resource becomes critically short or reaches a particular usage level, the resource manager selects one or more resource entities based on one or more criteria. For example, a resource entity which has the least restrictive resource usage policy or state is selected. The resource manager then requests that the selected resource entity changes its resource usage state to a more restrictive state. Of course, when resource usage reaches an acceptable level, the resource manager may also inform each resource entity (or previously selected resource entities) that they may set their resource consumption state to a less restrictive state.

A method and system that reduces the space allocated for internal data structures by a runtime engine. The internal data structures store member information for preloaded classes used by applications executed by the runtime engine. The system determines the different types of internal data structures represented in the classes and identifies thee possible values of each type's members. The system next determines the amount of space required to store the values for each type in a respective value table and the number of bits needed to index each entry of that table. The system determines based on the stored information whether occurrences of a member are optimally represented as a set of value table indices and a value table or, in the conventional manner, as a general variable that stores the member's value for each occurrence. The system then emits appropriate information for the member and its parent data structure.

One embodiment of the present invention provides a system that facilitates manipulation of three-dimensional (3D) objects displayed in a two-dimensional (2D) display. During operation, the system displays perspectively a 3D object in a 2D display based on a coordinate system with an X-axis along a horizontal direction on the 2D display, a Y-axis along a vertical direction on the 2D display, and a Z-axis along a direction perpendicular to the plane of the 2D display. The system further derives a 2D image from the 3D object and displays the derived image within a virtual 2D plane substantially parallel to the Z-axis, thereby allowing movement of the derived image within the virtual plane to reflect movement of the 3D object. The system also allows a user to manipulate the 3D object by manipulating the derived image within the virtual plane.

A video encoder/adapter comprises a virtual display module for partial rendering of a software application image. The virtual display module presents to the software application a virtual display device upon which the software application window is displayed. From the virtual display device, the user identifies one or more portions of the virtual software application window that are to be rendered on the actual display device.
