  • Patent number: 8006693
    Abstract: An aerosol transfer device for medical aerosol generators comprises an elongate shaped hollow member, located in a vertical plane constituting an aerosol storage area. The member has a first opening allowing entry of outside air. The first opening is located on an upper or lower horizontal surface of the member to ensure vertical air entry. A second opening opposite said first opening allows escape of aerosol, and a third opening serves for spraying aerosol into the storage area in the vertical plane and in axial alignment with the air inlet opening. The member has a minimum height of 6 cm and allows dispersion of the sprayed aerosol without recycling aerosol deposited on the walls. The member is located between an aerosol generator source and a patient interface and does not include any valve on the aerosol path from the storage area to the patient.

  • Patent number: 7997128
    Abstract: A device for counting the rotations of a tire on a vehicle using the deformations that the tire undergoes on each rotation of the wheel, comprising a casing, a sensor intended to generate an electrical signal on each rotation of the wheel, and connection means intended to mechanically connect the casing and the sensor to the surface of the tire. The sensor is in the form of a passive sensor in one piece with the casing, whereof the signals emitted are in proportion with the variations over time in a magnetic flux through the said passive sensor, and a magnetic field generator is arranged opposite the passive sensor. The connection means mechanically connect the casing to a first surface A and the magnetic field generator to a second surface B, the two surfaces A and B being substantially coplanar and offset from one another in a direction D by a given distance L. The electrical signal is produced by the relative displacements of the said passive sensor and the said magnetic field generator.
