Abstract

There are described a method, apparatus, and kit for validating an upgrade to a data acquisition system (DAS). The method comprises acquiring measurement data from a composite part using an upgraded DAS, the composite part representing a family of parts and having features from different parts of the family of parts incorporated thereon; comparing the measurement data to reference data defining tolerances for the measurement data; and validating the upgrade to the DAS based on the comparing of the measurement data to the reference data.

First claim

The invention claimed is:

1. A method for validating an upgrade to a data acquisition system (DAS), the method comprising:
acquiring measurement data from a composite part using an upgraded DAS, the composite part representing a family of parts and having features from different parts of the family of parts incorporated thereon;
comparing the measurement data to reference data defining tolerances for the measurement data; and
validating the upgrade to the DAS based on the comparing of the measurement data to the reference data.

2. The method of claim 1 , wherein the reference data is obtained from the composite part on at least one non-upgraded DAS.

3. The method of claim 2 , wherein the reference data is an average of data acquired from a plurality of the at least one non-upgraded DAS.

4. The method of claim 2 , wherein the reference data is an average of data acquired from the at least one non-upgraded DAS over a plurality of data acquisition cycles.

5. The method of claim 1 , wherein the upgrade is a software upgrade to the DAS.

6. The method of claim 1 , wherein the upgrade is a hardware upgrade to the DAS.

7. The method of claim 1 , wherein validating the upgrade comprises issuing a pass signal when the measurement data is within the tolerances.

8. The method of claim 1 , wherein the composite part has a known defect, and wherein validating the upgrade comprises issuing a pass signal when the known defect is detected.

9. The method of claim 1 , wherein at least one of the features corresponds to a complex feature of the family of parts.

10. An apparatus for validating an upgrade to a data acquisition system (DAS), the system comprising:
a processing unit; and
a non-transitory computer readable medium having stored thereon program code executable by the processing unit for:
acquiring measurement data from a composite part using an upgraded DAS, the composite part representing a family of parts and having features from different parts of the family of parts incorporated thereon;
comparing the measurement data to reference data defining tolerances for the measurement data; and
validating the upgrade to the DAS based on the comparing of the measurement data to the reference data.

11. The apparatus of claim 10 , wherein the reference data is obtained from the composite part on at least one non-upgraded DAS.

12. The apparatus of claim 11 , wherein the reference data is an average of data acquired from a plurality of the at least one non-upgraded DAS.

13. The apparatus of claim 11 , wherein the reference data is an average of data acquired from the at least one non-upgraded DAS over a plurality of data acquisition cycles.

14. The apparatus of claim 10 , wherein the upgrade is a software upgrade to the DAS.

15. The apparatus of claim 10 , wherein the upgrade is a hardware upgrade to the DAS.

16. The apparatus of claim 10 , wherein validating the upgrade comprises issuing a pass signal when the measurement data is within the tolerances.

17. The apparatus of claim 10 , wherein the composite part has a known defect, and wherein validating the upgrade comprises issuing a pass signal when the known defect is detected.

18. The apparatus of claim 10 , wherein at least one of the features corresponds to a complex feature of the family of parts.

19. A kit for validating an upgrade to a data acquisition system, the kit comprising:
a composite part representing a family of parts and having features from different parts of the family of parts incorporated thereon; and
a non-transitory computer-readable medium having stored thereon program code executable by a processing unit for:
acquiring measurement data from the composite part using an upgraded DAS;
comparing the measurement data to reference data defining tolerances for the measurement data; and
validating the upgrade to the DAS based on the comparing of the measurement data to the reference data.

20. The kit of claim 19 , wherein at least one of the features corresponds to a complex feature of the family of parts.
