Abstract: A system and method capable of detecting damage in a belt before catastrophic failure of the belt occurs. The system includes a belt having at least a first conductive component and/or at least a first dielectric component, and one or more pulleys to which the belt is mounted. At least a first of the pulleys has at least one conductive component that, in combination with the first conductive component or the first dielectric component of the belt, defines an electrical element. At least a portion of the electrical element is located within the belt so as to be physically responsive to transitory and permanent distortions of the belt resulting from extrinsic and/or intrinsic sources. Electrical potential is applied through the electrical element so as to generate an electrical signal from the electrical element corresponding to a physical response of the belt to a transitory and/or permanent distortion.

Abstract: A system and methods for predicting structural failure of at least a portion of a wall of a fluid containment vessel. The wall has an innermost layer for contact with a fluid contained by the vessel and an outermost layer parallel with the innermost layer. The system includes strain-sensing means within a portion of the wall and surrounded by the at least one reinforcement layer including at least one conductor parallel to the innermost layer of the wall. Changes are sensed in an electrical property associated with the at least one conductor resulting from distortion of the wall of the vessel causing distortion of the at least one conductor.
