Abstract: Improved microfluidic devices, systems, and methods allow selective transportation of fluids within microfluidic channels of a microfluidic network by applying, controlling, and varying pressures at a plurality of reservoirs. Modeling the microfluidic network as a series of nodes connected together by channel segments and determining the flow resistance characteristics of the channel segments may allow calculation of fluid flows through the channel segments resulting from a given pressure configuration at the reservoirs. To effect a desired flow within a particular channel or series of channels, reservoir pressures may be identified using the network model. Viscometers or other flow sensors may measure flow characteristics within the channels, and the measured flow characteristics can be used to calculate pressures to generate a desired flow. Multi-reservoir pressure modulator and pressure controller systems can optionally be used in conjunction with electrokinetic or other fluid transport mechanisms.

Abstract: A beverage dispenser for filling a container preferably has a nozzle through which the beverage is discharged and a pivoting lever located underneath the nozzle that detects the placement of a container so as to regulate the actuation of the dispenser. A conductive probe is in line with the discharged beverage stream, the lever also being conductive. A signal generator generates a varying-over-time signal that is applied to the probe or lever. As a result of beverage overflowing the container, the beverage stream establishes a conductive path between the probe and lever. The signal through this conductive path is compared to the signal produced by the signal generator. If the signals are substantially identical for a select period of time, the dispensing system is considered to be in an overflow state, and beverage dispensing is terminated.
