This application concerns the separation of fine granular mixtures that may occur when the grains are suitably vibrated within fluid. A support element is fixedly mounted at a milking box for an animal to be milked and positioned with the head at the front. A leader pin is inserted into a set of receptacles over the tape, and a clip is inserted into a pocket within an arm on the tool. The external circuit is disposed between the flexible substrate and the drive array substrate, located in the bonding region and extends outside the drive array substrate.
