Claim Text:
1. A system for inspecting the surface of a curved object, comprising: (a) an object having a curved surface, wherein the object includes a longitudinal axis and a circumference; (b) at least one substantially flat interdigital transducer, wherein the interdigital transducer is operative to generate surface energy waves; and (c) at least one six-sided coupling device disposed between the curved surface and the substantially flat interdigital transducer, wherein the at least one six-sided coupling device is operative to conform to the curved surface of the object, support the interdigital transducer, and provide a medium through which the surface energy waves can effectively travel from the interdigital transducer to the curved surface and across the curved surface in a predetermined direction, and wherein the at least one six-sided coupling device further includes:
