Abstract:
1. A fluidics circuit for controlling a plurality of fluid flows, the fluidics circuit comprising: a fluidics node having an outlet; a plurality of fluid inlets; at least one waste port; and a plurality of passages, each fluid inlet of the plurality of fluid inlets in fluid communication with a unique passage of the plurality of passages, the at least one waste port in fluid communication with the fluidics node by each passage of the plurality of passages without intervening valves, the plurality of passages having a fluid resistance selected so that when a fluid is selected to flow solely through a single fluid inlet of the plurality of fluid inlets a first portion of the fluid flows to the at least one waste port via an associated passage uniquely associated with the single fluid inlet without entering the fluidics node and a second portion of the fluid flows via the associated passage to the fluidics node, a part of the second portion exits the fluidics node through the outlet and the remainder of the second portion exits the fluidics node to the at least one waste port through the plurality of passages other than the associated passage uniquely associated with the single fluid inlet, another fluid entering one of the plurality of passages from an unselected fluid inlet of the plurality of fluid inlets is directed to the at least one waste port without entering the fluidics node.
