Abstract: A method and apparatus for routing data in a device having a plurality of parts. A signal is received at a first port. A detection is made that the first port received the signal. information contained in the signal is selectively routed from the first port to a data recovery circuit.

Abstract: A process and device are provided for achieving cascade flow to achieve rapid separations of target components from fluid mixtures is provided. The devices of the invention have a cascading flow channel. The separation processes of the invention may include singly or in combination, the step of adjusting the total voids volume in all elements employed in the devices of the invention to be equal to or less than 6% of the total volume of fluid that is to be processed. A single separation process or a combination of separation processes may be used where the fluid mixture is whole blood, whole blood that is diluted or is in some other way treated, concentrated, divided into two or more streams, or augmented with blood or blood components, cellular materials such as proteins, antibodies, enzymes and fractions thereof, and nuclear materials such as DNA, RNA and their fragments.
