Abstract: The present invention relates to a transducer (10) for non-invasive measurement. The transducer comprises a piezoelectric element (20), a base plate (30),anddriver electronics (40). The piezoelectric element is mounted to a first face (50) of the base plate. A second face (60) of the base plate is configured to be mounted to a wall (70) of a vessel. The vessel is configured to hold a liquid. The driver electronics is configured to drive the piezoelectric element at a plurality of activation frequencies. When the second face of the base plate is mounted to the wall of the vessel, the transducer when activated is configured to excite acoustic waves in the base plate and to launch an acoustic wave into the liquid. The transducer is configured such that an angular divergence of the acoustic wave launched into the liquid varies as a function of at least the activation frequency and an emitter dimension.

Abstract: The present application discloses a plasma reactor for a Dielectric Barrier Discharge (DBD) system. The system comprises one or more plasma reactor modules. The one or more plasma modules are configured as transmission lines. A duration of a rise-time and/or a fall-time of a voltage pulse, fed into a first end of the one or more reactor modules is shorter than a run-time of the voltage pulse from a first end of the one or more reactor modules to a second end of the one or more reactor modules.

Abstract: A Dielectric Barrier Discharge system controller for controlling a fluid treatment by a Dielectric Barrier Discharge system is provided. Therein, the strength of an effect caused by a discharge created by the Dielectric Barrier Discharge system is monitored, and the generation of high-voltage pulses by the high-voltage pulse generator (110) is controlled. The controlling of the generation of the high-voltage pulses is adapted based on the received sensor data.
