Abstract: A neural network has reduced requirements for storing intermodal weight values, as a result of a dual-precision training process. In the forward propagation of training samples, low-resolution weight values are employed. During back-propagation of errors to train the network, higher-resolution values are used. After training, only the lower resolution values need to be stored for further run-time operation, thereby reducing memory requirements.

Abstract: A font synchronization system ensures that fonts which are specified in the creation of a document are the same as those that are employed in the subsequent handling and printing of the document. Each font that is utilized within a document, or available in a printing system, is characterized by a font reference that unambiguously identifies significant features of the font. Font references associated with a document are compared with those available on a computer resource, to see if two fonts are the same in all significant respects. If the fonts are not the same, the comparison process identifies the areas of difference between them, so that a determination can be made whether such differences are critical to the appearance of the document. A number of font references are encapsulated within a font profile, to identify the fonts that are available for use within a particular environment, such as a service bureau.

Abstract: Structure, apparatus, and method for performing conservative hidden surface removal in a graphics processor. Culling is divided into two steps, a magnitude comparison content addressable memory cull operation (MCCAM Cull), and a subpixel cull operation. The MCCAM Cull discards primitives that are hidden completely by previously processed geometry. The Subpixel Cull takes the remaining primitives (which are partly or entirely visible), and determines the visible fragments.

Abstract: A method and system for dynamic language modeling of a document are described. In one embodiment, a number of local probabilities of a current document are computed and a vector representation of the current document in a latent semantic analysis (LSA) space is determined. In addition, a number of global probabilities based upon the vector representation of the current document in an LSA space is computed. Further, the local probabilities and the global probabilities are combined to produce the language modeling.

Abstract: Cable assembly housing. The invention includes a cable assembly housing. The cable assembly housing may include a main shell that defines a first cavity. The main shell may have a collar. The cable assembly may also include a cable shell that defines a second cavity. The cable shell may have three necks, two of which are disposed inside the first cavity, and the third neck is extended outside the collar. The cable shell may rotate about an axis of the main shell such that the cable shell is set at a predetermined angle and position with respect to the main shell.

Abstract: Windows in a graphical user interface are automatically repositioned and resized in response to changes in a display configuration. If a window is not capable of being fully displayed within the reconfigured display area, it is constrained to fit the available space. In determining the constraints for the window, the window is given a size which permits an integral amount of information to be displayed to the user. If a minimum required size is not already present in the available display area, the window is moved into the available area until the minimum size is attained. If the visible portion of the window already contains the minimum required area, a determination is made whether additional integral components of the window can be displayed. The window is then appropriately shrunk or expanded to permit an integral number of components to be displayed, and control elements are added to the window.

Abstract: A computing device is disclosed. The computing device includes a shock mount assembly that is configured to provide impact absorption to sensitive components such as a display and an optical disk drive. The computing device also includes an enclosureless optical disk drive that is housed by an enclosure and other structures of the computing device. The computing device further includes a heat transfer system that removes heat from a heat producing element of the computing device. The heat transfer system is configured to thermally couple the heat producing element to a structural member of the computing device so as to sink heat through the structural member, which generally has a large surface area for dissipating the heat.

Abstract: A multi-lingual indexing and search system performs tokenization and stemming in a manner which is independent of whether index entries and search terms appear as words in a dictionary. During the tokenization phase of the process, a string of text is separated into individual word tokens, and predetermined types of tokens are eliminated from further processing. The stemming phase of the process reduces words to grammatical stems by removing known word-endings associated with the various languages to be supported. Known word endings are removed from the word tokens without any effort to guarantee that the remaining stem is contained in a dictionary. In a preferred implementation, the stemming process is only applied to nouns.

Abstract: An improved hinge mechanism for use with a portable computing device is disclosed. The present invention relates to a hinge mechanism that is suitable for use in a portable computing device. According to one aspect of the present invention, a hinge mechanism that is used with a door in a portable computing device includes a spring coil, a stopper, and a pivot arm. The spring coil has a compressive state, e.g., the spring coil may be compressed or decompressed. The pivot arm is coupled to the stopper, and includes a first section as well as a second section. The first section is arranged to be positioned substantially within the spring coil, and the second section is arranged to be coupled to the door. Translational motion of the pivot arm causes the stopper to cause the compressive state of the spring coil to change. In one embodiment, the translational motion of the pivot arm causes the stopper to cause the spring coil to compress.

Abstract: Apparatus and techniques for awakening bus circuitry from an inactive state as needed are described. The bus circuitry forms part of a computer system and is placed in the inactive state (i.e., shut down) when not needed so as to conserve power. The bus circuitry is associated with a bus and can be awakened out of the inactive state when certain bus events, including resume, connect or disconnect, occur on the bus. The invention is particularly advantageous for computing devices (e.g., portable computers, desktop computers, server computers) where it is desirous to shut down bus circuitry as well as other circuitry (e.g., microprocessor) when not needed so as to reduce power consumption.

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.
