Abstract: A fluidic device which produces fluid pulses having a selected pulse repetition frequency, pulse duration, pulse peak pressure and pulse peak flow rate includes first, second and third fluid flow controlling channels or lumens which converge in a junction, defining a “Y” configuration having a base leg and right and left diverging arms. The first leg portion has a fluid input and terminates downstream at the Y junction of the base and the two diverging arms. The first leg has converging walls which reduce the cross sectional area of the flow to thereby increase the fluid velocity to make a fluid jet. The second or right leg, begins at the Y junction and terminates distally in an enclosed, fluid-tight container having a selected blind volume. The third, or left leg, begins at the Y junction and terminates distally in a fluid outlet passage having a selected cross-sectional area.

Abstract: Apparatus producing superheated water and/or steam for weed (36) killing, etc. has diesel fired boiler (30), which, via pump (32), generates hot water at a pressure of 40-52 bar and temperature of 90-115° C. This passes down tube (12) and encounters the constriction provided by nozzle (14). Passing through nozzle (14) into depressurization chamber (16), which is at atmospheric pressure, the water boils. When the super heated water exits ports (20) of distribution pipe (18) it encounters ambient temperature and is transformed into high temperature water vapor and/or water droplets. The apparatus controls or kill weeds (36) using a smaller volume of water and less energy.

Abstract: A hollow actuator-driven droplet dispensing apparatus may include an elastic tube having an elastic body, defining a storage space therein, and extending a predetermined length, and a hollow actuator fitted around the elastic tube so as to generate a force and a displacement in the longitudinal direction when an electric field is applied. The hollow actuator is expanded or contracted in the longitudinal direction of the elastic tube when the external voltage is applied, thereby reducing or enlarging the volume of an inner space of the elastic tube. The droplet dispensing apparatus can press the elastic tube to expand or contract the volume of the inner space of the tube using the hollow actuator capable of quickly generating a displacement in response to an application voltage so that a fixed amount of content can be discharged out and taken into the tube.

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.
