Appl. No.:

11/355956

Inventors:

James Q. Arnold - Summit NJ, US
Robert L. Doran - Milford NJ, US

Assignee:

Harris Corporation - Melbourne FL

International Classification:

H03M 13/00

US Classification:

714751, 714758

Abstract:

A system and method for transmitting IP packets arranged in an L×D matrix comprising data packets and L number of FEC packets, L corresponding to a number of columns in the matrix, and D corresponding to a number rows in the matrix includes assigning a first location in the matrix as an FEC packet location, skipping D number of locations in the matrix from the most recently assigned FEC packet location to a new location, and determining if the new location is positioned in the same column as an existing FEC packet location. The new location is assigned as an FEC packet location if it is determined that the new location is not positioned in the same column as an existing FEC packet location. If it is determined that the new location is positioned in the same column as an existing FEC packet location, then the location is moved back in the matrix until the moved-back location is not positioned in the same column as an existing FEC packet location, and the moved-back location is assigned as an FEC packet location. The skipping, determining, assigning, and moving back are repeatedly performed until the number of FEC packet locations is equal to L.

Abstract:

A cavity length control assembly for a ring laser gyro includes a mirror support to which a piezoelectric plate is mounted. The piezoelectric plate is mounted at a center post of the mirror support with a preload tension. An outer perimeter of the piezoelectric plate is supported against the perimeter of the mirror support, thereby permitting the piezoelectric plate to exert axial force against the perimeter, without being radially restrained at the perimeter.
