The control unit 1000 may be configured to generate each and every control signal, which is used for controlling each and every part of the device (such as the plurality 44 of liquid dispensers or other parts of the device).

[0309] The control unit 1000 may send each of the generated control signals to a dedicated part of the device (such as any one liquid dispenser in the plurality 44 of liquid dispensers) via the data output connecting means, and when each of the generated control signals is received by the dedicated part of the device, the dedicated part of the device functions according to the control signal sent from the control unit to the dedicated part of the device.

[0310] In at least some example embodiments of the device, the device comprises the electric plates 21 (FIG. 4).

In one example, the electric plates 21 may comprise a multitude of electrodes in the shape of rings positioned around the holes in the electric plates 21. The electric plates 21 or electrodes may be electrically charged so that electrical charge is accumulated in the electric plates 21 or in any of the electrodes in the multitude of electrodes so that a desired electric field is achieved. The electric plates 21 are configured so that the time-pattern of charging or discharging the electric plates 21 or the multitude of electrodes (and thus the presence of the desired electric field) are tightly synchronized with the stream 33 of carrier drops 10 (10a, 10b . . . ) in order to achieve a desired effect wherein the desired effect is that of: stabilisation of the carrier drop 10 trajectory, adjustment the carrier drop 10 trajectory, acceleration the carrier drop 10 trajectory, deceleration the carrier drop 10 trajectory, or any other manipulation of the carrier drop 10 trajectory. The carrier drop 10 trajectory may in this way be stabilised, or adjusted, or the carrier drops 10 may be accelerated or decelerated. Repeatability of the stream 33 of carrier drops 10 (10a, 10b . . . ) may thus be achieved so that the manipulation of the carrier drop 10 trajectory using electric fields exerted from the electric plates 21 enables compensation of the effects of collisions of the carrier drop 10 with other charge-free drops that collide with the carrier drop 10.

[0311] In at least one example, each electric plate 21 is made of uniform conductive material. In at least another example, each electric plate 21 is made of three (3) layers of materials: a layer of insulating material stacked between two layers of conductive material, and in such a case, the two conductive plates may be charged with opposite electrical charges which effectively form an electrical dipole. It is understood that depending on the charge of the carrier drops 10 and the desired effect of the electric fields exerted from the electric plates 21 on the carrier drop 10, voltage may either increase between two neighbouring electric plates 21 in the direction of the carrier drop 10 trajectory, or voltage may decrease between two neighbouring electric plates 21 in the direction of the carrier drop 10 trajectory. In this way, in at least some example embodiments of the device according to the present disclosure, the trajectory the carrier drops 10 (10a, 10b . . . ) in the stream 33 may be manipulated by using the electric fields exerted by the electric plates 21 which are mounted perpendicularly to the carrier drop 10 trajectory and have holes through which the carrier drop 10 passes. Electric plates 21 may be controlled by the control unit 1000.
