Abstract: Systems and methods for returning windows to an original location are described. When springing already open windows to a new location on a display space, it is desired to return that window to its original location for certain situations. A list is provided when the springing operation is initialized which captures information used to return the sprung window. According to exemplary embodiments, the relocation of various windows is tracked to ensure that each window is returned to an original location.
Abstract: A method and system for matching color displayed by source and destination display devices and particularly for providing color matching between a computer monitor and an ink printer. The technique of the present invention initially determines the combination and color value ratios of single destination color components that will cause the destination device to display a color that essentially matches each of fully saturated single and dual colors of a source display device. These combinations of single destination color components and their corresponding color value ratios determine the best available blends of destination device color components for printing source device colors. A color matching algorithm is employed to derive the color value ratios--one for each of the single destination color components.
Abstract: A method and apparatus is described for producing a translucent image over a base image created on the display screen of a computer system by a selected first application program, and conducting image operations either on the base image created by the selected application program with reference to the translucent image produced, or conducting image operations on the translucent image with reference to the base image of the first application program. The first application program runs on a central processing unit (CPU) of a computer system to produce a base image, and another application program referred to as the overlay program is run to produce the translucent image such that portions of the base image which are overlapped by the overlay image are at least partially visible through the translucent image. There is also a mechanism for blending the first video data and the second video data to produce a blended image on the screen assembly.

Abstract: A network system includes a font resource server that is accessible to all devices that communicate via the network. The font server contains the necessary information pertaining to the various types of fonts that may be required by users. This information describes the characters in a font in both a bitmap form and an outline form, so that either type of font information can be selectively employed at any given site. When a document is transmitted from the site of its creation to a remote site, the computer at the remote site first determines whether information pertaining to all of the fonts contained in the document is stored at the remote site. If not, the necessary font resources are downloaded from the font server to the remote site, via any suitable communication network. Once the resources have been downloaded, the document can be viewed and printed at the remote site.
Abstract: Aspects for achieving and utilizing synchronization among end stations in a wireless local area network (WLAN) are provided. In a method aspect, the method includes receiving a packet with a time synchronization field value from a first end station in a second end station of a communication group. The method further includes comparing upon receipt of the packet the time synchronization field value with a local time value in the second end station to determine whether the local time value requires updating to maintain synchronization between the first and second end stations. The comparing further determines whether a difference between the time synchronization field value and the local time value is greater than zero, and when the difference is greater than zero, the local time value is updated to the time synchronization field value.

Abstract: A variety of mechanisms are disclosed for a dynamically binding native methods in an interpreted bytecode program to functions that are contained in compiled code, such as a dynamically linked library. In one implementation, a shared function is specified by means of a naming convention that is appropriate for the bytecode interpreted program, such as a package of classes. When a native method is to be resolved during loading of a class, the name of the package is examined to see if the method resides in a shared library. If so, it is loaded using techniques that are specific to the compiled code in which the library exists. In another embodiment, a designated base class, or interface, is used to identify the method by which the shared library is to be loaded. In a third type of implementation, a given method requests a class to specify which libraries it needs to be linked to, as it is being loaded, after which the libraries are loaded and the class methods are linked to them.
Abstract: A method and an apparatus for improved duration modeling of phonemes in a speech synthesis system are provided. According to one aspect, text is received into a processor of a speech synthesis system. The received text is processed using a sum-of-products phoneme duration model that is used in either the formant method or the concatenative method of speech generation. The phoneme duration model, which is used along with a phoneme pitch model, is produced by developing a non-exponential functional transformation form for use with a generalized additive model. The non-exponential functional transformation form comprises a root sinusoidal transformation that is controlled in response to a minimum phoneme duration and a maximum phoneme duration. The minimum and maximum phoneme durations are observed in training data. The received text is processed by specifying at least one of a number of contextual factors for the generalized additive model.
Abstract: A method and device for accessing a broad data field having a fine resolution. The user selects a scale which can be varied. The scale controls a range within the data field. By moving the range to encompass different portions of the data field, the user can scan that portion of the data field. The present invention allows the user to simultaneously select the scale while moving the range over different portions of the data field. Thus, the user can "zoom in" and "zoom out" of different portions of the data field.In one embodiment of the present invention, a particular piece of data within the broad data field can be accessed. First, the scale is selectively varied, thereby controlling a range within the data field. Then, the range is moved to encompass portions of the data field in which the piece of data resides. Next, the scale is successively decreased while, simultaneously, points successively closer to the location are kept with the range. The scale is decreased (i.e.
Abstract: A method and apparatus for manipulation of data in a computer-controlled display system. A user may select data from a first application program and drag it to an area on the computer system display representing a third application program. The first application program creates a series of formats into which the data may be provided and, in some instance, the data itself. Moreover, a second process appends to that list of formats a series of formats that it can provide the data in. Then, upon receipt of the list of formats and/or data of the first item, the third process can request the data in any of the formats from either the first or second processes, if required.

Abstract: A new behavior in a graphical user interface allows the user to open and close enclosures, while dragging an object. When the user pauses, gestures, or rolls over a hot spot on top of an icon or text representing a closed enclosure, a temporary window for the closed enclosure is "sprung open" to allow the user to browse inside the enclosure and possible open another enclosure contained within the temporary window. This process can be carried on throughout a hierarchy of windows as the user browses for a destination window for the drag operation. All of the temporary windows except the destination are closed when the mouse button is released, signaling the end of a drag. The user may close sprung open windows by simply moving the cursor out of the sprung open window, or by making some other gesture.
