Method of utilizing product proxies with a dependency graph

Granted: October 21, 2008
Patent Number: 7441230
Changes to the outputs of a dependency graph, which has attribute nodes and operator nodes, are detected by forming product proxies for the outputs of dependency graph nodes. The product proxies can be formed by entering information about the dependency graph into a hashing algorithm. Before and after product proxies are then used to determine if the outputs have changed.

System and method of creating and animating a computer-generated image of a creature

Granted: April 10, 2007
Patent Number: 7202869
A to-be-animated creature is set up by creating a rig, defining connection points on the rig, and associating geometry with the rig via the connection points. The set up creature is then animated by moving the creature with user defined actions which move a part of the rig. When one part of the rig moves, the remaining parts follow.

Surround-sound system with motion picture soundtrack timbre correction, surround sound channel timbre correction, defined loudspeaker directionality, and reduced comb-filter effects

Granted: June 22, 1993
Patent Number: 5222059
Spectral imbalance (alteration in timbre) when playing home video versions of motion pictures having soundtrack equalized for playback in a room whose room-loudspeaker system is aligned to the standard motion picture theater X-curve is overcome by timbre correction which compensates for the X-curve equalization. Surround-sound home playback of motion pictures is enhanced by employing main channel loudspeakers that produce generally direct sound fields and surround channel loudspeakers…

Granted: February 4, 1992
Patent Number: D323694

Method and system for storing and retrieving multiple channel sampled data

Granted: August 5, 1986
Patent Number: 4604687
A method and system for recording and playing back from a bulk digital data storage medium having unequal access time, such as a rotating magnetic disk, data of a plurality of separate files, such as multi-channel sound information. Blocks of the digital data streams are stored in physically non-sequential scattered positions on a disk. The starting sectors of each recording track of the disk are not made the same but rather at least two different starting sectors are provided on…

Motion picture theater loudspeaker system

Granted: February 4, 1986
Patent Number: 4569076
A motion picture loudspeaker system is described in which the loudspeaker elements are integral with an acoustical boundary wall such that the characteristics of the vented box woofers are optimized. In order to overcome high reflection problems as sound from the tweeters is reflected by the motion picture screen and the acoustical boundary wall, frequency dependent acoustical absorptive material is attached to the wall to inhibit high frequency reflections with minimal effect on the…

Universal circuit prototyping board

Granted: June 18, 1985
Patent Number: 4524240
A universal multilayer circuit prototyping board is provided having a predefined universal pattern of socket pin perforations which accommodates all standard DIP integrated circuit packages at virtually any position on the board. The universal board allows high density circuit packing while maintaining excellent electrical performance with high speed circuits.

Toy figure

Granted: March 5, 1985
Patent Number: D277883

Toy vehicle

Granted: January 29, 1985
Patent Number: D277398

Linked list of timed and untimed commands

Granted: January 29, 1985
Patent Number: 4497023
One or more high speed programmable digital signal processors, particularly for audio processing such as mixing, sound effects and synthesizing, are supported by one or more slower speed computers that provide timed and untimed update commands to the high speed processors. Untimed commands are originated as by real-time operator gestures. Timed commands are originated by a master support computer. A queue of update commands is maintained in the high speed processor such that untimed…
