Abstract: The invention belongs to the field of medical sciences and respiratory masks. It is a cardiopulmonary resuscitation device that delivers assisted ventilation via a foot- or compressor-controlled bellows mechanism. This device frees the use of the hand used to compress the conventional self-inflating Airway Mask Bag Unit (AMBU), so that the free hand can be used to fit the mask over the patient's face and reduce the mechanical fatigue generated by the manual compression of current mechanisms. The unit attaches to ventilation masks, can have a frequency meter and is compatible with accessories comprising conventional cardiopulmonary resuscitation devices; inside it has a valve that controls the filling of the oxygen reservoir and the time at which oxygen is released to be supplied to the patient.

Abstract: A composite structure, including a laminate that includes a set of plies, the laminate extending between a first edge and a second edge and including a rising ramp and a falling ramp. The rising ramp includes a starting point and an upper point and the falling ramp includes the upper point and an end point. Plies are partially located over their preceding ply and alternatively extend from the first edge or the second edge and are shorter than the ply located before the preceding ply so that their ends are stepped successively until they reach the top of the ramp.

Abstract: A device provides electrical continuity between aeronautical components including a first fixed component and a second component displaceable with respect to the first component. The first and second components include electrically conducting surfaces. A first conductive piece is fixed to the first component and a second conductive piece is fixed to the second component. The first and second pieces are joined together with the possibility of sliding one on the other, in such a way that the first piece is connected to the conductive surface of the first component and the second piece is connected to the conductive surface of the second component, so that, when displacements take place of the second component with respect to the first component, the first piece slides on the second piece maintaining the electrical conductivity between the first and second components.
