<p><P>PROBLEM TO BE SOLVED: To provide a method and apparatus for simultaneously measuring current that flows through individual structures, in a multi-structure composite joint. <P>SOLUTION: The method includes the steps of inserting a printed circuit board between at least two structures, the printed circuit board being etched with at least one Rogowski coil sensory circuit, the two structures connected to at least one fastener, extending through the at least one Rogowski coil sensory circuit in the printed circuit board; detecting current in the at least one fastener by using the corresponding Rogowski coil; transmitting the detected current from each fastener to a corresponding passive integrator circuit for capturing transient pulses and integrating the pulses into an output: and transmitting the array output to a processing unit. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
