Abstract: An information processing device processes target information described using identifiers formed from a symbol, a product operator that joins together factors containing one or more of the identifiers and thereby forms a string of ordered factors, and a sum operator that joins together terms containing one or more of the factors and thereby forms an expression that is a combination of the terms. Also, information processing device includes a dividing unit that divides the target information into a plurality of terms at a predetermined position; and a transmission unit that associates positional information with at least any of the factors contained in the terms resulting from the division and causes each of the terms resulting from the division to be held in any of a plurality of server devices, where the positional information contains an occurrence sequence of the terms in the target information and an occurrence sequence of the factors in the terms.

Abstract: A motion analyzing method analyzes and displays motions of a human being or an animal using a computer in an interactive manner without requiring trial and error or without depending on intuition of an analyst. A human body or an animal body is divided into a plurality of segments connected by joints, each of the segments acting as a minimal unit of motion. Data for modeling the human or animal body on the basis of physical constraints and the inherent nature of each of the segments is maintained in a database. Motions are input to be analyzed and the input motions are analyzed using inverse dynamics. The resultant movements and the center of gravity of each of the segments, the force and torque exerted on each of the joints, the movement and the center of gravity of the whole body, and the forces and torques exerted on the centers of gravity are superimposed on the human or animal body model of the database and are displayed on a screen.

Abstract: A method for developing computer animation using dynamics analysis comprises analyzing the basic motions of a moving body such as a human or animal body and inputting the force or torque exerted on each joint into a database, dividing each body segment from other body segments and calculating the movements of the segments by applying dynamic equations, checking constraints including the articulation of the moving body and the range of movements of the joint, calculating motions and forces produced by the restraints by applying the inverse dynamics, calculating the movements of individual segments by applying dynamic equations to develop new motions, checking restraints including the articulation of the moving body and the range of movements of each joint, calculating the motions and forces due to the restraints by inverse dynamics, and displaying the motions and forces.

Abstract: An image data processing device having a multi-processor includes a plurality of local frame buffers, each coupled to a different one of a plurality of processors, and an image mixing device for mixing image data outputted from the local frame buffers periodically and transferring the mixed data to a screen, Each of the local frame buffers includes a demand paging device for assigning a memory unit of predetermined size to only a portion of the screen accessed by one of the plurality of processors to which the local frame buffer is coupled. The demand paging device includes a patch table for storing an assigning situation for the rectangular areas of the screen, Each patch of the patch table corresponds to the rectangular area of the screen, and stores information regarding an access to a portion of the screen by the one of the plurality of processors and address information of a memory unit assigned to the portion of the screen accessed by the one of the plurality of processors.

Abstract: A data base management system extending structure includes a data base management system and an extended data base language pre-compiler for pre-compiling an extended data base language into a data base language with which the data base management system can make an access. The extended data base language is added with a link attribute information to the data base language, where the link attribute information specifies relationships of representation objectives.
