Abstract: An improved theater surround sound system incorporates a screen top speaker and an overhead speaker driven by corresponding upper surround channels to more accurately reproduce sounds produced from above the listener. These top surround channels are encoded along with the left and right surround channels. A pilot signal is used to direct the sound from the side surround channels to the upper surround channels when needed.

Abstract: A character animation system executing on a computer. The system provides a simple, efficient and powerful user interface that allows the user to specify complex animations of multi-legged characters by placing footprints on a surface. The system automatically generates a natural looking animation based on the footprints. Motions such as walking, running, jumping, etc. are easily animated depending on the way footprints are placed. The user is able to create new footprint patterns and modify existing patterns. Footprint blocks on a timeline are used to specify the time duration that each foot is in contact with a footprint. The user may specify keyframes in the animation sequence that allow more complicated body movements to be incorporated with the footprint based animation.
Abstract: A system for determining selections that a user is likely to be interested in. The determination is made based on the user's prior indicated preferences. The user designates his or her preferred selections as entries in a user's preference list. Entries in the user's list are compared with entries in the other users' lists. When a significant number of matches have been found between two lists, the unmatched entries of the other user's preference list are extracted. The unmatched entries are further processed. Those unmatched entries with a high correlation to the user's preference list are presented to the user as selections in which the user is likely to be interested.
Abstract: Context sensitive help is provided by an application-external help system for a windowing environment. The help system is application-external in that it operates without the cooperation of an application or the help system supplied as part of the application. An object about which help is desired is selected by a user during the course of operation of an application program, and the help system uniquely identifies the object so that the help system can take appropriate action. Objects are uniquely identified by storing characteristics of each object, such as title, class, ID, style, number of child objects, number of parent objects, etc. An agent list contains, for each agent on the list, an event, an object string (including characteristics for each object) and an action.

Abstract: Link Ids are associated with file handles in a directory structure in a computer operating system. The Link Ids allow a file handle to be mapped uniquely to a pathname for a file associated with the file handle. In one implementation lists are used to facilitate fast searching of directory structures for a name associated with a Link Id. The list includes entry pairs where each entry pair is a Link Id and a directory number where a name associated with the Link Id may be found.
Abstract: A visualization system using a computer to provide a patient with a view of their internal anatomy based on medical scan data. The medical scan data is obtained from three-dimensional scanning system, such as Magnetic Resonance Imagery (MRI), Computer-Aided Tomography (CAT), Positron Emission Tomography (PET) and Nuclear Magnetic Resonance (NMR). The patient is presented with such data in an interactive virtual reality environment. The patient acts upon indications of the ailment within the virtual reality environment by using "tools" or other devices that produce a visual representation of the ailment being diminished in nature. This creates a psychoneuroimmunological response in the patient which aids the patient in combatting and recovering from the disease. Embodiments of the invention enhance the PNI response by providing more numerous and realistic sensory input in the form of, e.g., three-dimensional audio and high resolution volume rendering and animation.
