Filed:

Aug 15, 2002

Appl. No.:

10/219374

Assignee:

Sprint Communications Company, L.P. - Overland Park KS

International Classification:

G02B 600

US Classification:

Abstract:

A polarization scrambler and a polarization mode dispersion (PMD) compensation system compensate for PMD on an active optic fiber. The polarization scrambler scrambles a state of polarization of an optical signal that carries user information. The PMD compensation system then receives the optical signal over the active optic fiber. The PMD compensation system measuring a differential group delay and principal states of polarization of the PMD in the active optic fiber. The PMD compensation system then determines a modification of the optical signal based on the differential group delay and the principal states of polarization of the PMD. The PMD compensation system modifies the optical signal in the active optic fiber to compensate for PMD based on the determination of the modification. The PMD compensation system then transmits the optical signal. By measuring the differential group delay and the principal states of polarization, the PMD compensation system adapts to changes in the PMD in the active optic fiber.

US Patent:

Filed:

Apr 28, 2008

Appl. No.:

12/111066

Inventors:

Jonathan Cohen - Ann Arbor MI, US
Chris Allen - Los Angeles CA, US

Assignee:

Sony Corporation - Tokyo
Sony Pictures Entertainment Inc. - Culver City CA

International Classification:

G06T 13/00
G06F 7/60
G06F 17/10

US Classification:

345473, 345474, 345958, 703 2

Abstract:

A method for use in rendering includes receiving an input particle system, an instancing program, and a number indicating a maximum number of particles to be stored in memory, providing an input particle count representative of at least a portion of the input particle system to at least one operator for the instancing program, running the at least one operator in a prediction mode to generate an output particle count, comparing the output particle count to the number indicating a maximum number of particles to be stored in memory, and spatially splitting a bounding box representative of the input particle count in response to the output particle count being greater than the number indicating a maximum number of particles to be stored in memory.

Appl. No.:

12/111069

Inventors:

Jonathan Cohen - Ann Arbor MI, US
Chris Allen - Los Angeles CA, US

Assignee:

Sony Corporation - Tokyo
Sony Pictures Entertainment Inc. - Culver City CA

International Classification:

G06T 13/00
G06G 7/48

US Classification:

345474, 345958, 703 6

Abstract:

A method for use in computer graphics includes receiving data representative of a plurality of particles. For each particle, the method further includes calculating a time at which a collision will occur based on a current trajectory of the particle. For pairs of particles that will collide with each other, another operation includes changing a direction of the particles to avoid a collision, wherein the changed directions approximate directions that would result from the collision. For particles in static contact, another operation includes allowing particles to push each other without bouncing. For particles in static contact that were previously moved by being pushed, the method also does not allow the particles to move during future collisions occurring during a time step.
