Abstract: A device (30) for nebulizing a liquid includes a nebulization head (40) having a capillary tube (40-1) and a nozzle (40-2) for ejecting a liquid (43), a liquid supply tank (42) for supplying the nebulization head with liquid (43), a vibrator (44) for vibration driving the nebulization head so that it ejects droplets of liquid in a nebulization jet. The device (30) further includes a pressure regulator for applying to the liquid at the inlet to the nebulization head (40), during nebulization cycles, a pressure greater than a first pressure threshold above which the liquid flows through the nebulization head when the head is not vibration driven, and lower than a second pressure threshold above which the liquid flows through the nebulization head when the head is vibration driven. Advantages of the device include increase in the nebulization flow rate and low sensitivity to changes in trim and to vibrations.

Abstract: A control method for one or several devices for nebulizing liquids into the air (DF1), the method including control steps for the device to nebulize a liquid into the air according to nebulizing cycles during which a liquid is nebulized into the air, the nebulizing cycles being spaced by idle periods, and comprising adjustment of the duration of idle periods as a function of the average quantity of liquid to be nebulized per unit time selected, and as a function of a concentration parameter for the active product in the liquid to be nebulized. The method enables a same apparatus to treat volumes with a factor of 100 times, typically from 7 to 700 m3.

Abstract: The invention relates to a device for diffusing drops of at least one liquid, the device being of the type comprising at least one liquid displacement path defined by a series of pairs of close-together surfaces (4a, 6a, . . . , 14a) enabling liquid to be retained and to be displaced from one pair of surfaces to another. The device comprises: both a series of pairs of close-together surfaces (4a, 6a, . . . , 14a) defining at least one displacement path, and co-operating to store the liquid, to form drops of liquid, and to move liquid drops to an outlet from said path leading towards a drop destination site; and electric field application means applying a determined sequence of electric fields between the pairs of close-together surfaces so as to form drops of liquid from the liquid storage, and to move and mix the drops of liquid to the drop outlet of said path.

Abstract: A programmable odor-bearing substance diffusion device includes a number n of odor diffusion devices, where n is equal to or greater than 1, each odor diffusion device including a store of an odor source which is dispensed by the odor diffusion device, a device for independently controlling each odor diffusion device to emit a single odor or a mixture of odors from a by a combination of p of the n stores, and a programmable control device for establishing odor peak emission cycles and a predetermined interval between two successive emission cycles, the predetermined interval being based on an olfactory saturation and desaturation times of the olfactory system of a user.
