Abstract: Anti-vibration mount comprising first and second mounting members connected to each other by an elastomer body. The first mounting member comprises a head integral with the elastomer body and a connector rigidly fixed to the head by a connection permitting a degree of relative positioning tolerance between the head and the connector in a first direction. The head comprises a deformable stop that is interposed between the second mounting member and the connector, the deformable stop being capable of not obstructing the relative positioning tolerance between the head and the connector, and of abutting against the second mounting member by pressing against the connector in the first direction.

Abstract: A system, installed in the extension of a line across which an object or a person passes, includes: an optical device for projecting an image of this line onto a photosensitive sensor capable of providing an image signal; at least a processor for processing the image signal; and a screen, connected to the processor, for displaying an image representative of the image signal, called the video image, connected to said processor, wherein the sensor is formed of a pixel matrix. A reticule signal is generated and superposed onto the video image displayed on the screen, the system also being capable of generating electric signals originating from a pixel column which corresponds to the position of the reticule on the screen.

Abstract: A hydraulic anti-vibration device includes two rigid frame members, an elastomer body, two sealed chambers, a constricted passage putting the two sealed chambers into communication with each other, a valve member that defines portions of the two chambers and that has an axis of revolution, and two grids between which the valve member is interposed. The grids limit displacements of the valve member. Interposed non-uniformities cause the amount of contact the valve member has with a grid to vary progressively and angularly around the central axis of the valve member. The non-uniformities are disposed around the central axis in a distribution that is angularly non-repetitive.
