Automatic Test Sequence Generator
PROBLEM STATEMENT
When diagnosing a Unit Under Test (UUT), there exists a fault ambiguity group where a fault is known to exist, but the root cause cannot be isolated.
Automated Test Equipment (ATE) uses Test Program Sets (TPS) to diagnose these UUTs.
Naval Aviation spends $40 M yearly in acquiring new TPSs and each TPS may take up to 5 years to develop.
BENEFITS
Automatic generation of Test Program Sets
Eliminates man-hours needed for determining tests by hand, generating tests in a fraction of the current time
Generation of arbitrary waveform that is optimized to single out faults and remove ambiguity groups
TECHNOLOGY SOLUTION
Diagnostic unit that automatically optimizes stimulus signals for a UUT, allowing for higher fault coverage without increasing the number of test points
Evaluates a set of possible candidate stimulus signals by classification
Conducts selection of best candidates
Evolves best candidates by mixing and retaining characteristics of previous candidates
Unit automatically generates optimal set of signals to stimulate a UUT and detect and isolate faults, eliminating the need to create test program sets through current methods
Problem: Diagnostic Ambiguity in Electronic Equipment
Solution: Optimized Stimulus Separates Output Responses
