Filed:

Feb 14, 2003

Appl. No.:

10/367125

Inventors:

Dariusz Antoni Bushko - Hopkinton MA
Mehdi Kaveh - Westborough MA
John P. Voccio - West Newton MA
David D. Madura - Ashland MA
Alexander Perez - Framingham MA

Assignee:

American Superconductor Corporation - Westborough MA

International Classification:

H02K 1700

US Classification:

310208, 310179

Abstract:

A rotor assembly includes a substantially cylindrical support structure having at least one first region, and at least one second region. At least one rotor coil is positioned within each first region of the substantially cylindrical support structure. Each rotor coil includes a pair of distal end portions and a convex center portion, and the average mechanical density of the convex center portion is substantially equal to the average mechanical density of the distal end portions. The average mechanical density of the at least one first region is substantially equal to the average mechanical density of the at least one second region.

Mark Carrier - Houston TX, US

International Classification:

G06F015/16

US Classification:

709/227000, 709/246000

Abstract:

A network computer system and method are disclosed that provides access to a large number of concurrent clients without undesirable processor lag and delays. The system prepares client objects in advance of client access requests and can dynamically create new client objects over a distributed system when needed. Buffering is provided to avoid processor interrupts.
