Filed:

Oct 21, 1998

Appl. No.:

09/176658

Inventors:

Shih Mo - Milpitas CA
Chung Chang - San Jose CA

Assignee:

Maxtor Corporation - Longmont CO

International Classification:

H03M 1300

US Classification:

714781, 708507

Abstract:

A decoder for decoding block error correction codes is described. The decoder includes a first search circuit to find roots of an error location polynomial corresponding to an error location and a second search circuit to find roots of an error location polynomial corresponding to an error location. A multiplexer is fed by the first search circuit and the second search circuit to produce an error location from the error location polynomial.

International Classification:

G06F 1730

US Classification:

707200, 707205, 711173

Abstract:

An object, such as a relational database table, is partitioned into a plurality of subsets. Selected subsets, e. g. partitions, of the object are exported into a dump file, identifying each exported subset of data by writing a marker in the dump file. Selected subsets are imported from the dump file, by determining whether the marker in the dump file corresponds to the selected subsets, then conditionally importing the data associated with the marker. Objects are repartitioned by exporting the some of the subsets, reconfiguring the object, and importing the exported subsets back into the object.

Abstract:

Multimeric compounds that bind to P-Selectin Glycoprotein 1 (PSGL-1) on the surface of T cells or natural killer (NK) cells can be used to induce T cell or NK cell depletion and/or to induce T cell or NK cell apoptosis. The multimeric compounds and methods of the invention can be used to control unwanted T cell- or NK cell-mediated immune responses in conditions such as inflammatory diseases, autoimmune diseases, transplant rejection, and allergic diseases.
