    摘要： Focused acoustic radiation, referred to as tonebursts, are applied to a volume of liquid to generate a set of droplets. In one embodiment, a first toneburst is applied to temporarily raise a mound or protuberance on a free surface of the fluid. After the mound has reached a certain state, at least two additional toneburst can be applied to the protuberance to sequentially eject multiple bursts of multiple droplets. In one embodiment, the state of the mound can be maintained by a sustained acoustic signal, during which time multiple additional tonebursts can be applied to sequentially eject multiple bursts of multiple droplets from the mound.

    摘要： Focused acoustic radiation, referred to as tonebursts, are applied to a volume of liquid to generate a set of droplets. The droplets generated are substantially smaller in scale than the focal spot size of the acoustic beam (e.g., the frequency at which the acoustic transducer operates). Further, the droplets have trajectories that are substantially in the direction of the acoustic beam propagation direction. In one embodiment, a first toneburst is applied to temporarily raise a protuberance on a free surface of the fluid. After the protuberance has reached a certain state, a second toneburst is applied to the protuberance to break it into very small droplets. In one embodiment, the state of the protuberance at which the second toneburst is supplied is the time period shortly after the protuberance reaches its maximum height but before the protuberance recedes back into the volume of fluid.

    摘要： Methods of ejecting droplets containing a non-Newtonian fluid by an acoustic droplet ejector can include applying a tone burst of focused acoustic energy to a fluid reservoir containing a non-Newtonian fluid at sufficient amplitude to effect droplet ejection according to a tone burst pattern. The tone burst pattern may include three discrete tone burst segments, the first tone burst segment having greater duration than the second and third segments, and third segment having greater duration than the second segment. The exact durations and amplitudes of the tone burst segments can be tuned to influence the ejection properties.

    摘要： In a preferred embodiment of the invention, a closure for a container comprises at least two closure members. The relative position of the closure members with respect to each other is altered upon mating of the closure and container. The alteration of the relative position of the closure members may result in one or more of the members approaching the container more closely. The alteration may result in one or more of the members pressing against the container. The pressing may take place in such a way that exit paths for vapor from fluid in the container would require passage through the pressed surfaces.

    摘要： A system for fluid transport is provided where a quantity of fluid is held in a reservoir. A droplet generator is employed to generate droplets from the fluid, for example a nozzle-based system or a nozzleless system such as an acoustic ejection system. A generated droplet has a trajectory whereby it arrives at a target. A circuit is used to modify one or more characteristics of the generated droplet in a way which increases the likelihood that the droplet will not splash or bounce when it arrives at the target. The circuit may in different embodiments control the speed of the droplet or the Weber number of the droplet. The circuit may create an electric field in an area of space where the droplet passes. The circuit may charge the droplet by causing it to contact ions.
