Abstract
The present invention provides methods of assessing damage on a joint that includes energizing the joint, detecting the vibration of the joint using one or more signal generating sensors, processing the signal(s), and applying a damage index to the processed signal(s), wherein the damage index incorporates a processed control signal generated by a sensor(s) at or near the joint when the joint was healthy, i.e., in a substantially undamaged state. Another aspect of the present invention provides a pipeline that includes at least two pipe segments, at least one joint connecting the two pipe segments, and at least one signal generating sensor affixed to the pipeline that is capable of detecting vibration at or near the joint, at least one signal processor that is capable of EMD processing the signal, and an output device (e.g., computer monitor, LED display, a light bulb, an electronic alarm, or other sound or light generating device).
