Abstract

An adaptive inference system for testing electrical or electronic devices or assemblies. A method is provided for coordinating testing operations in a graphical test sequence presented upon a time dependent display. The method includes the steps of displaying the test data and information along the time dependent axis of a display screen using colored highlighting to identify regions of interest, using next fault searches to automatically locate highlighted areas and using windows positioned alongside data and channel labels along the time dependent axis for initiating an operation or test routine in the graphical test sequence.

Claims

1. In an adaptive inference system having an operative program for predicting causes of a previously unobserved fault appearing in an electric or electronic device or assembly from relationships with other known and previously stored fault data and information gathered for said electric or electronic device or assembly in prior tests, said adaptive inference system characterized by a method of displaying performance failures in a graphical test sequence presented upon a time dependent display, said method comprising the steps of:

a) displaying test data and information along a time dependent axis of a display screen, said test data containing performance data along all operative channels of said device or assembly, failures in performance along any of said channels being highlighted for ease of viewing, and said test information containing test evaluation information of said performance data including tolerance information, said test evaluation information being stored for comparison with data and information of prior tests to provide a figure of merit of a probable cause of failure; and

b) positioning at least one graphics sub-display on said display screen during said test.

2. The method displaying testing operations of claim 1, wherein said displaying test data step (a) includes displaying test data in analog form.

3. The method of displaying testing operations of claim 1, wherein said displaying test data step (a) includes displaying test data in digital form.

4. The method of displaying testing operations of claim 1, wherein said displaying test data step (a) includes displaying test data in both analog and digital form.

5. The method of displaying testing operations of claim 4, further comprising the step of:

c) editing both analog and digital test data.

6. The method of displaying testing operations of claim 1, further comprising the step of:

c) editing said test data being displayed, including adding test evaluations to said test data.

7. The method of displaying testing operations of claim 1 wherein said graphics sub-display comprises a pop-up window displayed adjacent to said test data.

8. The method of displaying testing operations of claim 1 wherein said graphics sub-display comprises a pull-down menu displayed adjacent to said test data.

9. The method of displaying testing operations of claim 1, further comprising the step of:

c) highlighting predetermined portions of data of said device or assembly, including highlighting data indicative of failures in performance of said device or assembly.

10. The method of displaying testing operations of claim 9, wherein said highlighting of said display is performed in a color.

11. The method of displaying testing operations of claim 10, wherein said color is red.

12. An adaptive inference system having an operative program for predicting causes of a previously unobserved fault appearing in an electric or electronic device or assembly from relationships with other known and previously stored fault data and information gathered for said electric or electronic device or assembly in prior tests, said adaptive inference system, including apparatus for testing and displaying performance of said electrical or electronic devices or assemblies in a test sequence presented in graphical form upon a time dependent display, comprising:

a) means for displaying test data and information respective of performance of said electrical or electronic device or assembly along a time dependent axis of a display screen, said test data containing performance data along all operative channels of said device or assembly, including means for highlighting failures in performance along any of said channels for ease of viewing, and said test information containing test evaluation information of said performance data including tolerance information, said test evaluation information being stored for comparison with data and information of prior tests to provide a figure of merit of a probable cause of failure; and

b) means for positioning at least one graphics sub-display on said display screen during display of said test.

13. The apparatus of claim 12, wherein said means for displaying test data includes means for displaying test data in analog form.

14. The apparatus of claim 12, wherein said means for displaying test data includes means for displaying test data in digital form.

15. The apparatus of claim 12, wherein said means for displaying test data includes means for displaying test data in both analog and digital form.

16. The apparatus of claim 15, further comprising:

c) means for editing both analog and digital test data.

17. The apparatus of claim 12, further comprising:

c) means for editing said test data being displayed.

18. The apparatus of claim 12, wherein said graphics sub-display further comprises means for displaying a pop-up window adjacent to said test results.

19. The apparatus of claim 12, wherein said graphics sub-display further comprises means for displaying a pull-down menu adjacent to said test results.

20. The apparatus of claim 12, further comprising:

c) means for highlighting predetermined portions of said display in addition to failure data.

21. The apparatus of claim 20, wherein said highlighting of said display is performed in a color.

22. The apparatus method of claim 21, wherein said color is red.
