The present invention relates to systems, methods and apparatus for improving the yield for separating components of fluids, for example biological or sensitive fluids such as blood, and improving the component yield, for example, from donated whole blood by separating its components by density in a centrifuge bowl with a multi-axial lumen. In one aspect, a plasma coil is provided that includes a first conductor coil that has a plurality of turns. Furthermore, in one embodiment, the invention comprises combining one or more statistical techniques with one or more non-statistical classification techniques. The first current collector is salient from the packaging and the second current collector is in contact with the metal layer. The ability to isolate andor authenticate the software andor hardware on or interacting with the unprotected software andor hardware provides for a secured system despite the presence or use of an unprotected computer device.
