A shielded cable connector which minimizes EMI and crosstalk between closely situated assembly modules is disclosed. The system in at least one embodiment includes an urine sensor, an infusion pump and a processor that controls the operation of the infusion pump at least in part from a signal received from the urine sensor. Each floating object has an x-y location in the document and has a position on a z-order stack. At least a portion of each of the conveyors is located in the upper chamber to catch materials fed into the flocculent. The tendency of such a layer to crack and form worm tracks is further reduced by exposing the substrate to a plasma preglow andor by using a slip agent on the side of the substrate on which the layers are to be formed.
