STOCHASTIC EVIDENCE AGGREGATION SYSTEM
First Claim
Patent Images
1. An information fusion system comprising:
- at least two diagnostic algorithms for providing belief values about a failure mode of a mechanism;
a filter for receiving the belief values from the diagnostic algorithms and providing smoothed belief values; and
an aggregator for aggregating the smoothed belief values into at least one diagnostic state.

Abstract
A system for obtaining diagnostic information, such as evidence about a mechanism, within an algorithmic framework, including filtering and aggregating the information through, for instance, a stochastic process. The output may be an overall belief value relative to a presence of an item such as, for example, a fault in the mechanism.
