Abstract: Multiple unique keyed fluid connectors that are not cross-connectable with each other are described. Each keyed fluid connector comprises a first body including a first mating surface and having a first fluid fitting disposed in a first port in the first mating surface; a second body including a second mating surface opposable to the first mating surface and having a second fluid fitting disposed in a second port in the second mating surface, the second fluid fitting connectable to the first fluid fitting; and a keying feature comprising at least a first pin extending from one of the first and second bodies and disposable in a first hole in the other of the first and second bodies. The connectors are particularly useful in providing a robust system for selecting a particular electrolyte from among several containers of different electrolytes, and dispensing it into an implantable power device.

Abstract: A resistance welding electrode that is particularly suited for resistance spot welding a workpiece to a substrate without cross-contaminating specific portions of the workpiece is described. This is done by sheathing an internal surface of the welding electrode with a thermoplastic polymeric material. Then, there is only contact between the welding electrode and the workpiece at the very distal end of the electrode adjacent to where the workpiece is to be connected to the substrate. Contamination in this area is not detrimental because subsequent workpiece plating does not take place there.
