Claim Text:
1. A microfluidic system comprising: a first fluid channel having a first end and a second end, the first fluid channel having a length extending from the first end to the second end, the first end coupled to a first fluid reservoir or a second fluid channel, the second end coupled to a second fluid reservoir or a third fluid channel; a first fluid actuator located at a first distance from the first end along the length of the first fluid channel, the first fluid actuator to generate first and second waves, respectively, propagating toward the first end and the second end of the channel to produce a first unidirectional net fluid flow from the first end to the second end; a second fluid actuator located along the length of the first fluid channel at a second distance from the first end different from the first distance, the second fluid actuator to generate third and fourth waves, respectively, propagating toward the first end and the second end of the channel to produce a second unidirectional net fluid flow from the second end to the first end, neither the first fluid actuator nor the second fluid actuator located at a midpoint of the length of the first fluid channel; and a controller to selectively activate the first or second fluid actuator to cause either the first unidirectional net fluid flow or the second unidirectional net fluid flow through the first fluid channel.
