Abstract: An aerosol generator for generating an inhalation aerosol from an inhalation liquid, includes an intake duct for guiding air to a mouth of a user, and a nozzle, arranged in the intake duct for injecting the inhalation liquid into the intake duct. The nozzle is arranged for generating a Rayleigh droplet train of the inhalation liquid propagating along a droplet train propagation path. The intake duct includes at least two first orifices having at least partly opposing discharging directions extending towards the droplet train propagation path. The at least two first orifices are configured for providing respective first air streams in at least partly opposing directions so as to interact in the droplet train propagation path.

Abstract: Embodiments relate generally to marine geophysical surveying and, more particularly, embodiments relate to methods for acquiring geophysical data by dynamically manipulating survey spread in response a change in location of a target. A method may comprise actuating an energy source in a body of water, wherein a target for a marine geophysical survey system is located beneath a bottom of the body of water. The method may further comprise detecting energy generated by the energy source. The method may further comprise manipulating a position of a survey spread in response to a change in distribution of the target beneath the bottom of the body of water.
