20070246108, Oct 25, 2007

Filed:

Apr 19, 2006

Appl. No.:

11/406917

Inventors:

Timothy Conway - Huntington Beach CA, US

International Classification:

F16L 37/36

US Classification:

137614060

Abstract:

A quick-disconnect, the nipple portion of which has a pressure relief path and a coupler portion of which has a safety lock. The nipple portion is provided with a spring-loaded sleeve which covers the relief flow path when not engaged. The sleeve is hand driven against the spring load to expose the flow relief passage. Any pressure in the quick-disconnect is then discharged to atmosphere. The coupler portion incorporates a piston that is pressure activated to block the motion of a disconnecting sleeve. The piston is moved to the unlocked position by a wave spring when the pressure is removed. These features are packaged in a small volume for use in systems where space is limited. The quick-disconnect is designed and fabricated with materials that can withstand a proof pressure of 20,000 PSI. Such capabilities are especially useful in aircraft systems with a supply pressure of up to 5,000 PSI. The pressure relief assures the quick-disconnect can be relieved of any residual pressure up to 5,000 PSI before it is uncoupled and the lock assures that it can not be uncoupled without pressure relief.

Appl. No.:

7/266722

Inventors:

Patricia M. McCown - Creskill NJ

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

G06F 1518

US Classification:

364550

Abstract:

A diagnostic tool based on a hybrid knowledge representation of a system under test is disclosed. Data collected from the system during its operation is compared to an event based representation of the system which comprises a plurality of predefined events. An event is recognized when the collected data matches the event's critical parameter. The recognized event is analyzed and an associated set of ambiguity group effects, which specify components to be re-ranked in an ambiguity group according to an associated ranking effect. Additonally, a symptom-fault model and a failure model can be analyzed to determine symptom-fault relationships and failure modes which are applicable to the system operation. Each applicable symptom-fault relationship and failure mode is also associated with a set of ambiguity group effects which rerank the ambiguity group. A structural model is analyzed starting with the components in the ambiguity group having the greatest probability of failure.

International Classification:

G06F 1574

US Classification:

364550

Abstract:

Method and apparatus for performing system monitoring and diagnostics is disclosed. In performing system monitoring, data is acquired from the system under test and compared to an event model. The event model comprises a database having event records which pre-define events which can occur. Each event record includes a state vector dependency which lists the events which must occur prior to the pre-defined event occurring and one or more critical parameters defining the data which must occur during the system's performance for the event to have occurred. Event recognition is performed by comparing each event record to acquired operational data and to events already recognized. Associated with each event record in the database is an intelligent data acquisition action which defines an action to be taken as a result of the event record being recognized. These actions can modify the performance of the system being monitored or the acquisition of data. Additionally, the results of the event recognition step can be further analyzed in a computer.
