Abstract: The invention relates to an inter-arch component comprising a body (10) which has a U-shaped plate (11). the plate (11) having an upper face (11c) configured to bear against an upper dental arch of a wearer, and a lower face (11d) configured to be oriented towards a lower dental arch of the wearer, and the body (10) additionally having a graduated rule (17) which extends transversely to the plate (11) and which is configured to measure a distance between the upper dental arch and the lower dental arch. It also relates to a use of such an inter-arch component and to a method for producing an intraoral protector (IOP) having such an inter-arch component.

Abstract: A mouthguard able to be shaped in the mouth, has an adaptable structure consisting of an adaptable material, and a skeleton, at least partially covered by the adaptable structure, consisting of a non-adaptable material. The mouthguard also has a removable pallet consisting of a non-adaptable material and comprising a first region intended to butt against the skeleton, the region of the pallet being dimensioned such that, during the adaptation phase of the mouthguard, the combined presence of the pallet and of the skeleton ensures both ventilation space and the presence of sufficient material at the incisor-canine area.

Abstract: To reduce buffeting caused by separation on the wings of an aircraft, a parameter representing the buffeting in amplitude, frequency and phase is measured. The measuring signal is subjected to filtering intended to establish the characteristics of at least one mode of vibration of the wings and, by actuating a control surface according to a non-stationary law, in a localized region the wings, of alternate stresses are generated whose amplitude and phase are automatically determined to dampen one or several modes of vibration of the wings.

Abstract: A process and an installation for the control of the efficiency of the aerodynamic surfaces of an aircraft, whereincontrol of the stability of flying aircrafts with the assistance of orientable auxiliary aerodynamic surfaces is achieved,the surfaces are connected to their operating structure through a device providing at will an engaged condition or a disengaged condition, andthe process and installation may be used with profit on subsonic, supersonic and laboratory airplanes.
