Appl. No.:

09/663610

Inventors:

Tibor Farkas - Orange CA
Brian Byungkyu Kim - La Mirada CA
Bich Ngoc Nguyen - Los Angeles CA

Assignee:

The Boeing Company - Chicago IL

International Classification:

G01M 308

US Classification:

73 405R, 73 46, 73 491

Abstract:

A leak detection system for use with a fluid conducting system in a vacuum environment, such as space, is described. The system preferably includes a mesh-like member substantially disposed about the fluid conducting system, and at least one sensor disposed within the mesh-like member. The sensor is capable of detecting a decrease in temperature of the mesh-like member when a leak condition causes the fluid of the fluid conducting system to freeze when exposed to the vacuum environment. Additionally, a signal processor in preferably in communication with the sensor. The sensor transmits an electrical signal to the signal processor such that the signal processor is capable of indicating the location of the fluid leak in the fluid conducting system.

International Classification:

US Classification:

12820423, 12820421, 12820426

Abstract:

A system and method of controlling the termination of the inhalation phase in a pressure support ventilation system is disclosed, in which an expiratory trigger sensitivity, or ratio of inspiratory flow rate to peak inspiratory flow rate at which the inspiration phase is terminated, is varied in proportion to variations in a calculated respiratory time constant. The system includes sensors for monitoring pressure and flow of gas during each breath, and, based on the sensor outputs, calculates the respiratory time constant for one breath or a series of breaths. The expiratory trigger sensitivity is automatically increased with increasing patient respiratory time constant, providing a closed loop control of expiratory trigger sensitivity. The expiratory trigger sensitivity may also be varied in response to changes in supra-plateau pressure.

Abstract:

An insulation package comprising a layer of material having a cellular structure disposed between a first layer of high-strength polymeric fabric and a second layer of high-strength polymeric fabric. The insulation provides protection for critical fluid systems, such as fuel, hydraulic, electrical, pneumatic, thermal, and mechanical systems from high-energy projectiles such as fragments from the disintegration of high-speed turbines and engines.

Appl. No.:

8/638247

Inventors:

Bich Ngoc Nguyen - Fountain Valley CA

Assignee:

Unisys Corporation - Blue Bell PA

International Classification:

G06F 1120

US Classification:

395280

Abstract:

A two domain network linking a first and second data processing system enables efficient data transfers between modules in the first system and modules in the second system through linkage by bus exchange modules having message queues and snoop-write address queues in each domain. Each system also allocates bus access using a selectively adjusting bus access priority arbitration logic unit. The Snoop-Write address queues in each bus exchange module can temporarily hold a sequence of Write OP addresses snooped from one domain for invalidation in another domain without requiring the bus exchange module to dominate its access priority over other requesting modules.

Unisys Corporation - Blue Bell PA

International Classification:

G06F 1300
G06F 1340

US Classification:

711146

Abstract:

A two domain digital network with each domain having its own system bus and its own bus exchange module permits Write operation addresses to be passed between domains. Each bus exchange module provides a match filter which prevents the passage from one bus to the other bus of a duplicate Write operation (OP) address which has already been transferred, thus relieving the busses of excess traffic when a duplicate Write OP address is being sent to a cache memory for an invalidation operation. A Read operation will nullify the match filter to then allow passage of each incoming Write OP invalidation address to the snoop invalidation queue, but prevent the passage of a subsequent duplicate Write OP address, so long as the read OP is ongoing.

International Classification:

H04L 29/06

US Classification:

709231

Abstract:

A method is provided in one example embodiment and includes identifying a bit rate associated with an adaptive streaming client that is engaged in a media session, where the bit rate is used to maintain a particular video quality for a media stream. The method also includes using a network virtual player to lock the bit rate for a particular time interval for the adaptive streaming client; and supporting the bit rate from a network for the adaptive streaming client during the media session. In more particular embodiments, the method can include detecting a plurality of congestion points flow instrumentation; and reducing a committed service rate for the virtual player based, at least in part, on the flow instrumentation.
