Remote diagnostics and prognostics methods for complex systems
First Claim
1. A system for monitoring performance of an apparatus, comprising:
- a plurality of operational components functioning in said apparatus, each operational component with a predetermined nominal operating state and each generating respective electrical signals pursuant to their operation;
a data collection memory in said apparatus storing samples of said electrical signals in a rolling buffer;
an analyzer in said apparatus responsive to said electrical signals for detecting a trigger event indicative of at least a potential variance of an operational component from its nominal operating state;
a computation center located remotely from said apparatus and having a database storing representations of electrical signals for classifying nominal and irregular operating states of said operational components; and
a transmitter activated by said trigger event to transmit at least some of said stored samples in said rolling buffer at the time of said trigger event to said computation center;
wherein said computation center receives said transmitted samples and classifies them according to said nominal or irregular operating states.

Abstract
A diagnostic/prognostic system monitors performance of a vehicle or other apparatus wherein the vehicle has a plurality of operational components. Each operational component has a predetermined nominal operating state and generates respective electrical signals pursuant to its operation. A data collection memory in the vehicle stores samples of the electrical signals in a rolling buffer. An analyzer in the vehicle is responsive to the electrical signals for detecting a trigger event indicative of at least a potential variance of an operational component from its nominal operating state. A computation center located remotely from the vehicle has a database storing representations of electrical signals for classifying nominal and irregular operating states of the operational components. A transmitter is activated by the trigger event to transmit at least some of the stored samples in the rolling buffer at the time of the trigger event to the computation center. The computation center receives the transmitted samples and classifies them according to the nominal or irregular operating states.
