Patent number: 9927220Abstract: A method of inspecting components between a pre-coated state and a post-coated state is provided. The method entails providing at least first and second datum points onto the component in the pre-coated state, where each of the at least first and second datum points have a substantially hemi-spherical shape and a center point. The center points of each of the at least first and second datum points are utilized for measurement of a selected portion on the component in the pre-coated state. Then, the component is coated. Next, the center points of each of the at least first and second datum points are utilized for measurement of the selected portion on the component in the post-coated state. The pre-coated state measurements and the post-coated state measurements are then correlated for inspection purposes.Type: GrantFiled: December 18, 2013Date of Patent: March 27, 2018Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Thomas H. Rogers, Randall W. Joyner, James R. Murdock, Andrew J. Brinks, Michael A. Morden

Patent number: 7573586Abstract: A method of measuring a coating thickness involves projecting a pattern of light on a surface. A first reflection of the pattern of light is received by a first image capturing device. A second reflection of the pattern of light is received by an image capturing device which may be the same or a different image capturing device. The first reflection is compared with the second reflection. A first dated map of the surface is created by comparing the first reflection and the second reflection. A coating is deposited on the surface. A second data map of the surface with the coating is created by comparing reflections. The first data map and the second data map are then compared to determine a thickness of the coating.Type: GrantFiled: June 2, 2008Date of Patent: August 11, 2009Assignee: United Technologies CorporationInventors: Jesse R.
