| Number | Title | Issue Date |
| 7076516 | Efficient method of identifying non-solution or non-optimal regions of the domain of a function A method of identifying one or more regions of the domain of a function that do not contain solutions is described along with a related subdivision method. These methods may be employed in the context of branch and bound methods that use interval analysis to search ... | 07/11/2006 |
| 7061483 | Methods for computing barycentric coordinates generalized to irregular n-gons and applications of the same A method for deriving barycentric coordinates for a point p within an n-sided polygon is provided wherein, for a particular coordinate wj, corresponding to the vertex qj, the method embodies a formula which depends only on the edge pqj | 06/13/2006 |
| 6828966 | Method of deriving mesh surface representation from volume representation A method of extracting a mesh representation of a surface from a volumetric representation of at least a portion of an object is provided. A surface is derived from the volumetric representation. A seed point on the surface is then selected, and a neighborhood of th... | 12/07/2004 |
| 6573897 | Real-time, interactive animation of deformable two- and three-dimensional objects A method of updating in real-time the locations and velocities of mass points of a two- or three-dimensional object represented by a mass-spring system. A modified implicit Euler integration scheme is employed to determine the updated locations and veloci... | 06/03/2003 |
| 5999660 | Imaging system for correction of perceptual distortion in wide angle images An imaging system which corrects perceptual distortion in wide angle picture balances between direct view distortion and linear perspective distortion. The two kinds of distortion are balanced according to a transformation ratio. The balancing can be expr... | 12/07/1999 |
| 5442583 | Compensated analog multipliers The multiplier which includes built-in adjustments to improve circuit performance. More specifically, the multiplier is a compensated multiplier to increase the accuracy and precision of computation using analog very large scale integrated (VLSI) circuits... | 08/15/1995 |
| 5381361 | Method and apparatus for real-time constraint solution A circuit and method for executing real time constraint solution permits real time control of computational tasks using analog very large scale integrated (VLSI) circuits. The constraints of a computation or task are first defined as a function or set of ... | 01/10/1995 |
