Abstract

An electronic test system with a progress window that enables the user to observe in one glance the progress and status of a test. The progress window is preferably comprised of graphical elements representing test results grouped along a progress axis representing the length of the test procedure. Each graphical element is preferably displayed as a bar, with the length of the bar perpendicular to the progress axis representing the value of the result. The specifications limits are represented by lines parallel to the progress axis. A line above the progress axis represents the upper specification limit and a line below the progress axis represents the lower specification limit. The bars are color coded to display the pass, fail and marginal status of the test.

Claims

1. An electronic test system comprising:

a memory for storing a test procedure including a plurality of measurements; and

a plurality of datapoints corresponding to test results for said plurality of measurements;

an electronic processor communicating with said memory for controlling the execution of said procedure and displaying said test data; and

a graphical user interface output device communicating with said electronic processor for displaying information, said information including a plurality of datapoint units, each datapoint unit consisting of a single graphical element having at least two dimensions and conveying the results of said test for a corresponding datapoint, said datapoint units grouped in a manner to display the progress of said test procedure.

2. An electronic test system as in claim 1 wherein said graphical elements are grouped along a progress axis, and the distance said elements extend along said progress axis represents the length of said test procedure.

3. An electronic test system as in claim 1 wherein said graphical elements each comprise a bar.

4. An electronic test system as in claim 3 wherein said graphical elements are plotted as colored bars perpendicular to said progress axis.

5. An electronic test system as in claim 3 wherein said memory further stores a specification limit for each of said datapoints and a value for each of said test results, and each of said graphical bars have a length proportional to the ratio of the value of said result, corresponding to said graphical bar, to said specification limit for said datapoint.

6. An electronic test system as in claim 5 wherein said memory further stores upper and lower specification limits for each of said measurements and said information further comprises a first specification limit element representing said upper specification limit and a second specification limit element representing said lower specification limit.

7. An electronic test system as in claim 6 wherein said upper and lower specification limit elements are graphical lines.

8. An electronic test system as in claim 7 wherein said graphical elements are grouped along a progress axis, said upper specification limit is a line positioned above and parallel to said progress axis, and said lower specification limit is a line positioned below and parallel to said progress axis.

9. An electronic test system as in claim 3 wherein the length of said graphical bar perpendicular to said progress axis is normalized to said specification.

10. An electronic test system as in claim 9 wherein the length value of said normalized graphical bar is compared to 1 so as to indicate the status of said result.

11. An electronic test system as in claim 10 wherein said status is selected from the group consisting of pass, fail and marginal.

12. An electronic test system as in claim 1 wherein said graphical elements are color coded.

13. An electronic test system as in claim 12 wherein said color code indicates a status selected from the group comprising pass, fail and marginal.

14. An electronic test system as in claim 13 wherein said color code comprises three colors, each said color corresponding to one of said pass, fail and marginal statuses.

15. An electronic test system as in claim 14 wherein each of said graphical elements is a bar, and said color is assigned to each of said bars according to its length.

16. An electronic test system as in claim 1 wherein said procedure comprises a plurality of measurements to be applied to a product selected from the group consisting of electronic, electromechanical and mechanical products.

17. An electronic test system as in claim 1 wherein said memory stores instructions for communicating with said electronic, electromechanical and mechanical products.

18. A method for displaying the results of an electronic test comprising the steps of:

performing a test procedure comprising a plurality of test measurements to determine a plurality of datapoints, each said datapoint corresponding to the result of one of said test measurements;

displaying a plurality of graphical units, each said graphical unit representing one of said datapoints, each of said graphical units comprising a single graphical element having at least two dimensions; and

grouping said graphical elements in a manner to display the progress of said test procedure.

19. A method as in claim 18 wherein said step of displaying comprises displaying a plurality of graphical bars, each of said graphical bars corresponding to one of said graphical elements.

20. A method as in claim 18 wherein said step of grouping comprises plotting said graphical elements along a progress axis representing the length of said test procedure.

21. A method as in claim 18 wherein said step of displaying comprises plotting the graphical elements as colored elements.

22. A method as in claim 18, further including the step of storing a numerical value and a specification limit value for each of said datapoints.

23. A method as in claim 18 wherein said step of displaying further comprises displaying said specification limit value.

24. A method as in claim 23 wherein said step of displaying said specification limit value comprises plotting said specification limit value as a line.

25. A method as in claim 24 wherein said step of plotting comprises plotting said graphical elements along a progress axis representing the length of said test procedure, plotting an upper specification limit as a line above and parallel to said progress axis, and plotting said lower specification limit as a line below and parallel to said progress axis.

26. A method as in claim 18, and further including the step of normalizing each of said graphical elements.

27. A method as in claim 26, and further including the step of storing a specification limit for each of said datapoints, and said step of normalizing comprises dividing the value of each of said datapoints by the corresponding specification limit.

28. A method as in claim 27 wherein said wherein said step of displaying comprises plotting each of said graphical elements as a graphical element having a length determined by said step of normalizing.

29. A method as in claim 28 wherein said step of displaying comprises plotting said graphical elements along a progress axis representing the length of said test procedure and plotting said graphical elements in a direction perpendicular to said progress axis.

30. A method as in claim 27 wherein said step of storing comprises storing an upper specification limit and a lower specification limit for each of said datapoints, and said step of normalizing comprises normalizing said value of said datapoint for both said upper specification limit and said lower specification limit.

31. A method as in claim 28 wherein said step of displaying comprises plotting said graphical elements along a circular coordinate representing the length of said test procedure and plotting said graphical elements in a radial direction.

32. A method as in claim 18 wherein said step of displaying comprises displaying said graphical element in color so as to convey the pass, fail and marginal status of said datapoint.

33. A method as in claim 32 wherein said step of displaying further comprises assigning a green color for a bar corresponding to a pass status, assigning a yellow color for a bar corresponding to a marginal status, and assigning a red color for a bar corresponding to a fail status.
