A nebulizer system for a motor vehicle may include a tank for a liquid, a nebulizer chamber, and a filter system capable of filtering the liquid contained in the tank for the liquid before it passes into the nebulizer chamber. The nebulizer chamber may have a nebulizer nozzle provided with an acoustic wave output device such that the liquid from the tank forms a mist of droplets of the liquid. The mist is intended to pass into a passenger compartment of the motor vehicle. Additionally, the nebulizer system may have an input module for air. The inlet module may have an air injection volute capable of channeling the air in the direction of the internal volume of the nebulizer chamber.

A fog distribution head for a fogging apparatus, which has: a fog inlet, and at least two fog outlets, each suitable for placing the inlet in communication with the outside of the head. The head includes at least two plugs suitable for plugging the respective outlets. Each plug is suitable for plugging a single one of the outlets, the plugs being movably mounted with respect to a frame of the head, independently from one another.

The device for diffusing sprayed liquid in a reception zone includes a vessel suitable for containing a liquid for spraying and at least one diffuser of sprayed liquid that is arranged in the vessel. The diffuser includes in particular an ultrasound emitter. The cleaning method is such that during a stage of operation of the device in which the device is not diffusing liquid in the reception zone, the following steps are performed: heating a liquid in the vessel up to a predetermined temperature, preferably higher than 60&#xb0; C., in particular lying in the range 65&#xb0; C. to 80&#xb0; C.; and draining the liquid from the vessel via a pipe of the device that is situated outside a circuit for diffusing sprayed liquid in the reception zone.

A liquid spraying device including an elongate first vessel closed at one of its ends by a first free face of a piezoelectric transducer capable of emitting waves into a liquid filling the vessel, and open at its end remote from the piezoelectric transducer. The piezoelectric transducer includes a second free face opposite its first free face, and wherein an elongate second vessel is disposed symmetrically to the first vessel relative to the piezoelectric transducer, the second vessel being closed at one of its ends by said second free face of the piezoelectric transducer, which is thus also capable of emitting waves into a liquid filling the second vessel, said second vessel being open at its end remote from the piezoelectric transducer.

A method of predicting the formation of water condensation on a surface in contact with humid air includes the steps of placing on the surface an element that adopts initially a temperature approximately equal to a temperature of the surface. The element is thermally cycled. Each cycle includes a cooling phase and a heating phase. The cooling phase includes first and second steps. Electric current is supplied to a cooling mechanism in the first step of the cooling phase to decrease the temperature of the element to below the temperature of the surface. An electric current is supplied to the cooling mechanism in the second step of the cooling phase to further decrease the temperature of the element. The current of the first step is greater than the current of the second step, such that the temperature of the element decreases more rapidly in the first step than in the second step. The formation of water condensation on the surface is predicted based upon the formation of water condensation on the element.

The invention relates to a spraying device including a tank which is open at its upper part, capable of containing a liquid to be sprayed, such as water, while being filled up to its opening, a piozoelectric element capable of emitting waves into the liquid and fan means for creating a circulation of air in the vicinity of the surface of the liquid. The waves are focused in the vicinity of the opening of the tank, and the cross-section of the tank (1) has a progressive constriction towards the opening (2) of the tank (1).

A process is disclosed to detect a water condensation risk on a surface in contact with a wet air volume, which uses the steps of (a) placing a sensitive element on the surface, which initially takes a temperature corresponding to that of the surface, (b) by means of a heating device on this sensitive element, initiating a first heating phase until a temperature higher than the surface temperature is reached, (c) by means of a cooling device having the same thermal power as the heating device, initiating a cooling phase until a temperature lower than the surface temperature is provoked on the sensitive element, and (d) a comparison is made between the ratio of the first heating phase time to the temperature rise during heating and the ratio of cooling phase time to the temperature decrease during the cooling, a noticeable difference between these two ratios indicating a significant risk of condensation on the surface.

A piezoelectric rotating motor includes a plurality of piezoelectric elements, a disk-shaped stator having a center portion in which the piezoelectric elements are accommodated, a circular friction zone which is formed on an outer peripheral portion of its one surface and a connecting portion which connects the center portion with the friction zone so as to form a lever transmitting and amplifying the axial strain of the piezoelectric elements to the portion of the friction zone located in the same angular sector as the piezoelectric elements and which has a cone shape at rear side of the friction zone so as to thin its thickness from the center portion to the outer peripheral portion and producing a progressive wave forming an elliptical vibration on the friction zone by the composition of its three dimensional strain due to the piezoelective effect of the piezoelectric elements and a rotor being contracted with the friction zone under pressure.

A Peltier effect device which detects in particular a condensation risk, includes a substrate and semiconducting bands disposed on the upper face of the substrate. The junctions connecting said bands which make up a series circuit are formed by semiconducting bands of N-type and P-type. Junctions of the same type, i.e., N-P type are situated on the central zone of the upper face of the substrate and defines a detection zone of the device. Semiconducting bands of one type are placed on one side of the upper face of the substrate and bands of the other type are placed on the other side of the upper face of the substrate. The substrate also includes at the peripheral zone of each band, except for a frontmost N-type band and a rearmost P-type band, a plated hole extending through the substrate to a lower face of the substrate and to a plating of the lower face such that a plated hole situated at an end of the P-type band is connected to a plated hole situated at an end of a next N-type band.
