Abstract: Electronic-fluidic hybrid form dividers, constructed by a simple planer droplet generation structure, a pair of signal electrodes, and a responsive control valve, which is programmed to respond to only certain signal droplets, by a basic electronic principle: change of voltage share between impedances. Detected fluidic information is addressed in both electronic and fluidic forms, and the fluidic pathway is well-confined in a simple planar structure, although its control valve is in a second layer, thereby minimizing any fluidic disturbance. Various configurations comprise a plurality of identical structures, which can alter their cumulative function by re-assignment of required voltage share. The hybrid divider can be assembled into a fluidic universal logic gate, of a simple two inlet and one outlet signal channels structure, and switch between sixteen functions by re-assigning voltage share.

Abstract: A microfluidic dispensing system may include multiple supply lines for simultaneous filling of diaphragm pumps associated with each supply line. Each supply line may fill corresponding groups of diaphragm pumps with a corresponding ingredient to a supply reservoir for the supply line. Accordingly, different groups of diaphragm pumps corresponding to different supply lines may be filled with corresponding ingredients simultaneously. Those ingredients corresponding to the different groups of diaphragm pumps may also be dispensed simultaneously, giving rise to a faster and more efficient fluidic dispensing system.

Abstract: A meter for flowing material, e.g., water, has a meter register having an electronic display, e.g., an LED or LCD display, and a mechanical read-out display driven by a stepper motor to record units of water that flowed through the meter. In the event of an electrical power failure, the LED or LCD readout values are lost, however, the mechanical read-out values remain. Further, signals are transmitted to a microprocessor of a meter register to change the rotation of the stepper motor so that the meter register can be used with different types of meters. Still further, a meter generator co-acting with a meter register forwards an electrical pulse signal after a quantity of material or utility passes through a water meter to a microprocessor of a remote reader. The remote reader includes an odometer coupled to a stepper motor.

Abstract: The advanced modified high performance synthetic jet actuator with optimized curvature shape chamber (ASJA-M) is a synthetic jet actuator (SJA) with a lower volume reservoir or chamber. A curved chamber is used, instead of the conventional cylinder chamber, to reduce the dead volume of the jet chamber and increase the efficiency of the synthetic jet actuator. The shape of the curvature corresponds to the maximum displacement (deformation) profile of the electroactive diaphragm. The jet velocity and mass flow rate for the ASJA-M will be several times higher than conventional piezoelectric actuators.
