Patent ID: 7680624

Claim:
A method for performing a real-time root-cause-analysis for a degradation event associated with a component under test, comprising: using at least one computer for: monitoring a telemetry signal, wherein detecting an anomaly in the telemetry signal involves applying a sequential probability ratio test (SPRT) to the telemetry signal and a time derivate of the telemetry signal and detecting an anomaly when the SPRT generates an alarm; collected from the component, and while doing so attempting to detect an anomaly in the telemetry signal; and when an anomaly is detected in the telemetry signal, performing a failure analysis on the telemetry signal by fitting the degrading telemetry signal to a time-dependent failure function in real-time while the telemetry signal is degrading; and attempting to identify a failure mechanism for the telemetry signal based on the failure analysis.
