Patent ID: 7231826

Claim:
A non-destructive inspection device for inspecting a feature of a structure, the inspection device comprising: an actuating portion having at least one magnet, wherein the actuating portion is structured for placement on a first surface of the structure such that the actuating portion is movable relative to the structure; a first inspecting portion having a first inspection sensor and at least one magnet, and a second inspecting portion having a second inspection sensor and at least one magnet, wherein the first and second inspecting portions are structured for positioning on a second surface of the structure opposite the first surface such that the feature of the structure to be inspected is located between the first and second inspecting portions, wherein the first and second inspecting portions are magnetically coupled to the actuating portion so that movement of the actuating portion causes the first and second inspecting portions to move in concert with the actuating portion without the first and second inspecting portions directly contacting the actuating portion, and wherein the first and second inspecting portions are in a generally fixed relative position with respect to each other when each is magnetically coupled to the actuating portion.
