Abstract: A monocular head mounted display system that is convertible between a right eye display system and a left eye display system includes a generally symmetrical frame. A flexible support arm moveably mounted on the frame, supports an image display module. The image display module includes a display and optical system to project an enlarged image at a distance from the user. With the frame in a first position with the image display module below the frame, the image is viewable by a user's right eye. The system is converted by moving the support arm so that the display module is above the frame in the first position and then the frame is flipped over to an inverted position with the display module again below the frame but the image viewable by the user's left eye.

Abstract: A system is disclosed for the three-dimensional representation of scenes and/or objects from planar layer images which are obtained from scaled representation planes in the spatial depth of the scenes and/or objects. To this end, a plurality of adjacent representation elements are provided, wherein said elements are perpendicular to the vision direction of an observer or a camera. The representation elements are arranged relative to each other so as to define a flat raster comprising a plurality of lines and columns. Two at least of these adjacent representation elements, in a line and a column of this raster, have different focal distances. The number of different focal distances corresponds to the number of scaled representation planes in the spatial depth. The representation elements having the same focal distance are always associated with the same representation planes. A portion of a planar layer image is placed in the optical axis of each representation element.

Abstract: A pressurized slip joint for a marine intervention riser decouples the flowhead assembly in the moon pool of a vessel from the riser string, enabling safe changeover of equipment during workover operations. One part of the slip joint assembly is coupled to the flowhead assembly through a flexible joint assembly. A second part of the slip joint assembly supports the riser string and is coupled to the tensioning mechanism. The first part may be inserted into the second part and locked in place during workover operations except when equipment changeover is taking place. When changeover is being carried out, the first and second parts are unlocked, so that the flowhead assembly does not move relative to the vessel. In the locked position, a metal-to-metal high pressure seal, with a secondary and tertiary seal controls the pressure in the riser. In the unlocked position, a hydraulically operated dynamic low pressure seal is used.

Abstract: An indicating light display for a motor vehicle, and in particular a raised stop light in the form of a strip which contains a plurality of light sources, also includes optical processing means for redirecting the light received from the light sources so that it will be propagated in the general emission direction. The display thus consists of a series of light cells, each defining a transition zone between each cell and the next. The optical processing means include, in association with each light source, a first element for distributing the light, in a plane at right angles to the general emission direction, on a second element in the form of an optical plate. This optical plate is divided into zones each associated with one of the cells and formed with projecting striations. Each transition between a zone and the next zone is formed with a transition striation which receive light from both of the two adjacent light sources and redirects this towards the general emission direction.
