Abstract: An ultrasound probe holding device configured to attach to the head of an infant for transfontanellar imaging is disclosed, including a head pad configured to be in contact with the head of the infant and including a central opening, wherein the head pad is configured to receive an ultrasound probe; a pad squeezer, including a central opening and configured to cooperate with the head pad to allow an axial guidance of the head pad along a guidance axis substantially perpendicular to a surface tangent to the head of the infant; a device holder configured to be attached to the head of the infant and exert a downward force on the pad squeezer, along said guidance axis; and a repellent configured to exert a repellent force between the pad squeezer and the head pad when the device holder exerts the downward force on the pad squeezer.

Abstract: A multiple-sensor tracking method, notably implemented in an air traffic control system, making it possible to reduce the latency time introduced by the tracking system, characterized in that the correlation (302) and association (303) functions work on the basis of membership of the detections (502) and of the tracks (503, 504) to cells (510, 511) defining a subdivision into a grid (501) of the surveillance area represented on a stereographic projection plane.

Abstract: An apparatus for gas treatment for a bath of liquid aluminum at rest in a furnace having a roof and in which the bath has a surface area of at least 10 m.sup.2. The apparatus comprises a movable gantry placed over the furnace and from which are suspended at least three gas injector assemblies which are more than 2 m long each. The injector assemblies are partially immersed in the bath through openings in the roof of the furnace and the immersed parts are separated from each other solely by the bath. The assemblies each comprise a rotary shaft having a rotor at its lower end joined to a plurality of blades. Through the axis of the shaft there is a cavity which opens above the furnace and which communicates at its lower end with passages in the blades. Means are provided above the furnace for rotating the shafts and for connecting the cavities to a source of treating gas.
