Abstract: A fluid testing system comprises controlling hardware that serves to control an electric sensor on a fluid testing cassette. In one implementation, the controlling hardware is part of a cassette interface. In another implementation, the controlling hardware is part of the portable electronic device. In one implementation, the fluid testing system applies two different frequencies of alternating current are applied to two different electric sensors.

Abstract: A microfluidic diagnostic chip may comprise a main fluid channel comprising a main pump, a secondary fluid channel branching off from the main fluid channel, and a secondary pump within the secondary fluid channel wherein the secondary pump is to pull a particle of analyte of a first size from a fluid passing through the main channel, the fluid comprising particles of analyte of the first size and of a number of larger sizes. A method of analyzing an analyte on a microfluidic chip may comprise pumping, with a main microfluidic pump, a fluid comprising an analyte particle through a main microfluidic channel fluidly coupled to a fluid slot and sorting the analyte particle within the fluid through a secondary microfluidic channel by pulling the analyte particle into the secondary microfluidic channel with a secondary microfluidic pump.

Abstract: A device includes a microfluidic channel structure on a substrate with a first fluid actuator and a second fluid actuator within the microfluidic channel structure. One of the fluid actuators is selectively employable to at least partially reverse fluid flow within at least a portion of the microfluidic channel structure in response to a blockage or to prevent a blockage.

Abstract: A printhead includes a plurality of firing chambers, a plurality of fluid ejectors, and at least one field generating member. Each one of the firing chambers includes a nozzle region to receive printing fluid. The printing fluid includes an ink vehicle having pigments disposed therein. At least one field generating member generates a non-uniform electric field to apply forces to maintain respective pigments in the ink vehicle of the printing fluid in the nozzle region.

Abstract: In some examples, a fluid system includes a support structure to attach a fluid dispensing device comprising a fluid chamber to contain a fluid, and an orifice to dispense the fluid from the fluid chamber. The fluid system includes a circulation path comprising a path portion in the fluid dispensing device, the circulation path to circulate a fluid flow through the fluid chamber to remove, from the fluid chamber, a particle ingested through the orifice. A filter in the circulation path is to remove the particle from the circulation path.

Abstract: A fluidic die may include a fluid channel layer defining a number of fluid channels therein, a slot layer disposed on a side of the fluid channel layer, and a first fluid slot and a second fluid slot defined in the slot layer. At least one of the fluid channels fluidically couples the first fluid slot to the second fluid slot. The first fluid slot and the second fluid slot are defined in the slot layer along a length of the fluidic die.
