25 Oct 2011TL;DR: In this article, a control unit for controlling the operation of a nebulizer is provided that is configured to measure the impedance of an actuator in the nebulizers and determine whether a ne-bulizing element is positioned correctly with respect to the actuator on the basis of the measured impedance.
Abstract: A control unit for controlling the operation of a nebulizer is provided that is configured to measure the impedance of an actuator in the nebulizer and to determine whether a nebulizing element in the nebulizer is positioned correctly with respect to the actuator on the basis of the measured impedance. Also provided is a nebulizer comprising a reservoir chamber for storing a liquid to be nebulized, an actuator for vibrating liquid stored in the reservoir chamber, and a control unit as described above.

02 Aug 2011TL;DR: In this paper, a method for controlling the concentration of ions in a liquid comprises the steps of generating a main stream (1) of liquid, applying a transverse electric field to the main stream by electrodes that are electrically in direct contact with the liquid, and deriving a product stream (2) from the central region of the main streams, and waste streams (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20, 21, 22, 21) from regions
Abstract: A method for controlling the concentration of ions in a liquid comprises the steps of: - generating a main stream (1) of liquid; - applying a transverse electric field to the main stream by electrodes that are electrically in direct contact with the liquid; - deriving a product stream (11) of liquid from the central region of the main stream, and waste streams (12, 13) of liquid from regions of the main stream closer to said electrodes.
