Abstract: 16 Animation data is produced in a data processing system that has storage, a processor, a visual display (102) and a manual input device (103). A simulated three-dimensional world-space is displayed to a user and an animatable actor is displayed in the world-space. First input data is received from a user specifying a desired location and orientation of the actor to which the actor is to animate towards from a starting location. The processor is instructed to generate first animation data using a first processing technique possibly using a forward kinematic solver. The processor is instructed to generate second animation data using a second processing technique, in response to the same input data, possibly using an inverse kinematic solver. Second input data defines a blend parameter for blending between the first animation data and the second animation data. Output animation data is produced by interpolating between the first animation data and the second animation data to extents controlled by the blending parameter.

Abstract: A method system for tracking the state of an entity (e.g., an object) on behalf of a client (e.g., an application program). The states of an entity include up and down. The tracking system of the present invention receives a request from a client to track the state of an entity. The tracking system then watches the state of the entity to detect when the entity enters the up state. When the entity enters the up state, the tracking system performs a behavior that is specified by the client to be performed when the entity enters the up state. When the entity is in the up state, the tracking system monitors the state of the entity to detect when the entity enters the down state. When the entity enters the down state, the tracking system performs a behavior that is specified by the client to be performed when the entity enters the down state. When the tracking system receives a request from the client for a pointer to the entity, the tracking system determines the current state of the entity and either provides a pointer to the entity or indicates that a pointer is not being provided.

Title: Resynchronization of control and data path state for networks
Inventor: ASHWOOD SMITH PETER J
IPC: H04L69/40
Filed: 2002-12-16
Abstract: In a switching protection system, a protocol is followed by a first connection controller to help facilitate the resynchronization of the network after the failure has occurred. This protocol contains the messaging system of the ability to query and store the exact sequence of logical ports and time slots that make up the data path, as a resynchronization table coupled to the first controller. The head/ingress end of the path can receive this information during set-up and can store it both locally and in shadow locations. The system also contains the ability to distinguish between signaling and data channel failures, as signaling channel failures to do not clear cross connect data but simply leave it "ownerless". The system also contains the ability to populate the exact sequence of logical ports and time slots accumulated in the definition of the network, as the set-up message initiated by the head controller to re-claim "ownerless"  cross connections contained on respective network elements. The system also facilitates the clearing of a "ownerless" cross connection after a pre-determined period of time has lapsed.

Abstract: An array of autoantibodies is quantitated in a patient sample and analyzed toward a diagnosis of systemic autoimmune diseases. The analysis uses any of  various known pattern recognition techniques to compare the array of quantitation data to sets of data previously obtained from subjects having known systemic autoimmune diseases, thereby determining the particular disease(s) that the patient is suffering from as well as the degree of confidence or likelihood of accuracy of the determination. The method is effective in identifying a single disease and also in identifying two or mor e diseases simultaneously present. The method is readily susceptible to automated data processing, eliminating much of the human judgment and error that were previously entailed in diagnosing these diseases.

Title: Motion compensation of images
Inventor: CLAYTON JOHN CHRISTOPHER
IPC: H04N5/44
Filed: 2001-11-05
Abstract: Motion compensation of a sequence of image fields (0-5) is carried out in the frequency domain using phase correlation (10) between corresponding picture areas of a pair of time-spaced, input fields (1, 4) to produce a set of motion-vector estimates that are used for filtering the relevant areas of each field (1; 4) of the pair by interpolation (11; 12) with the corresponding area of its preceding and following input-fields (0, 2; 3, 5) of the sequence, to produce a frame-approximation to that field (1; 4) through combination of the individually-filtered areas. The filtering in each case involves respective application (24-26 of weighting coefficients to corresponding spatial-frequency components of the relevant picture areas of three fields, and summation (28) of the weighted components, the coefficients being calculated or selected (27) according to the motion-vector estimate associated with each picture area. Repetition of the phase-correlation step (13) using the frame-approximations refines each motion-vector estimate for repeating the three-field interpolation processes (14, 15) to derive better frame-approximations.  Transformation from the frequency to special domain (34) takes place after two or more reiterations, or when convergence is reached for all constituent picture areas.
