| 20080208882 | Method of Assisting Users In Detection and Correction of Errors In Complex Databases - A method and system for conflict detection during construction of complex databases, such as a data model for driving or modeling a complex system. Components of a data model may be defined in rules that specify objects of various types and containing various elements. The rules are declarative, and may be stored on a computer-readable storage medium. Rule declarations or assertions include element definitions, values or ranges of values, inclusion requirements, and severity level conditions in the event that conflicts or errors are detected. Conflict checking takes account of compliance with type definitions, as well as a user identity and a phase of construction of the data model. | 08-28-2008 |
| 20080319603 | AREA HEALTH MANAGERS FOR AIRCRAFT SYSTEMS - An aircraft system includes an aircraft subsystem generating monitor trips related to the health of the aircraft subsystem; and an area health manager coupled to the aircraft subsystem. The area health manager includes a data receiver for receiving the monitor trips from the aircraft subsystem; a fault detector for processing inputs based on the monitor trips to identify faults; and an execution sequence queue coupled to the fault detector for storing a plurality of execution entities. Each of the plurality of execution entities is associated with a specific logic operation in the fault detector that is executed when the associated execution entity is in a first predetermined state. | 12-25-2008 |
| 20090262722 | Method to Calculate Transitive Closure of Multi-Path Directed Network Based on Declarative MetaData - A method for modeling the response of a system to an input signal, wherein metadata describing characteristics of individual system components is combined to identify how signals received at one system component cascade through the system. | 10-22-2009 |
| 20090327202 | PREDICTION OF FUNCTIONAL AVAILABILITY OF COMPLEX SYSTEM - A method, system, and computer program product for predicting the functional availability of a complex system is provided. Parameters of the complex system are converted from a plurality of binary values to at least one prognostic vector. At least a portion of a binary input expression is converted into an equivalent fuzzy output expression, the fuzzy output expression operable on the at least one prognostic vector. | 12-31-2009 |
| 20100042366 | DISTRIBUTED DECISION MAKING ARCHITECTURE FOR EMBEDDED PROGNOSTICS - A distributed decision making architecture for embedded prognostics in a platform is provided. An estimation system determines at least one performance characteristic of at least one device in the platform. A supervisory system is in communication with, and superior to, the estimation system. The supervisory system calculates a prediction of remaining useful life (RUL) of the at least one device in the platform. The supervisory system is adapted for collecting the at least one performance characteristic from the estimation system to generate a performance estimate, and implementing at least one data-driven equation to match the at least one performance estimate against of at least one known degradation condition to generate the prediction of remaining useful life of the at least one device. | 02-18-2010 |
| 20100042872 | RECURSIVE STRUCTURE FOR DIAGNOSTIC MODEL - A recursive mapping structure for diagnostic models is provided. A parent diagnostic model includes a first input module, a first output module, a first monitor module coupled to the first input and first output modules, and a first propagation module coupled between the first input and first output modules. A child diagnostic model includes a second input module, a second output module, a second monitor module coupled to the second input and second output modules, and a second propagation module coupled between the second input and second output modules, wherein the second monitor module is coupled to the first monitor module. | 02-18-2010 |
