Abstract:
The present application relates to a method for determining multiple simultaneous fault conditions on complex systems. The method comprises receiving symptoms of a complex system from monitors. When some of the symptoms suggest the existence of multiple simultaneous fault conditions, then the method creates a symptom signature, creates one or more failure mode signatures, and creates an error code for each failure mode signature in regard to the symptom signature. Each failure mode signature is associated with only one failure mode. A Hamming distance is determined for each failure mode indicated as possibly causing the original fault condition. Each failure mode with the minimum Hamming distance and same Hamming Code are grouped together as being one of the multiple simultaneous fault conditions. All remaining failure modes with other Hamming distances are then assigned into one of the simultaneous fault conditions.
Abstract:
A system and method for providing remote access to an on-board aircraft system provides establishing communication between an aircraft server that is located within the aircraft and a remote computer that is located outside of the aircraft. In the aircraft, a request is received to establish a remote session between the remote computer and the aircraft server. A passcode is generated in the aircraft, and is transmitted from a first communication device that is collocated with the aircraft to a second communication device that is collocated with the remote computer. The passcode is then transmitted from the remote computer to the aircraft server and, upon receipt of the passcode by the aircraft server, the remote computer is provided with remote access to the on-board aircraft system.

Abstract:
A method for accumulating fault condition data from a hierarchical system is presented comprising monitoring an operation of a component with a computing node that includes a processor and a memory. The memory contains a configuration file comprising failure modes (FM), symptoms, tests that identify the symptoms and a corrective action for the symptom. The method further comprises populating at least one of the processor and the memory of the computing node with one or more standardized executable application modules (SEAM) and a workflow service. The one or more SEAMS is configured to create a fault condition record by collecting all FMs that manifest the symptom. For all FMs collected, a list of unique symptoms is produced. Further all tests that can identify the listed unique symptoms and all of the corrective actions associated with the FMs that manifest the symptom are determined from the memory device.

Abstract:
Systems and Methods are provided for coordinating computing functions to accomplish a task. The system includes a plurality of standardized executable application modules (SEAMs), each of which is configured to execute on a processor to provide a unique function and to generate an event associated with its unique function. The system includes a configuration file that comprises a dynamic data store (DDS) and a static data store (SDS). The DDS includes an event queue and one or more response queues. The SDS includes a persistent software object that is configured to map a specific event from the event queue to a predefined response record and to indicate a response queue into which the predefined response record is to be placed. The system further includes a workflow service module, the work flow service module being configured to direct communication between the SDS, the DDS and each of the plurality of SEAMs.
