Abstract: A system for positioning of a road construction machine of the type paver. The system comprises a first measuring unit configured for continuously generating first measuring data in a first detection range during a movement of the road construction machine and comprising at least a first camera and a first LiDAR sensor module, wherein camera and LiDAR data are recorded covering the first detection range with minimum repetition rate and minimum resolution, and several markers. The system further comprises a data memory, wherein the data memory has stored a 3D design model referenced with respect to a 3D construction site coordinate system and information about a known absolute reference of the several markers in the 3D construction site coordinate system, and a computing unit.

Abstract: An air vent has at least one first control lamella that is pivotably mounted in a housing, and a second lamellae extending orthogonally to the first control lamella. For controlling the amount and direction of outflowing air, an operating element is pivotable mounted about an axis that extends parallel to the pivot axis of the second lamellae, and which is coupled to a first adjustment element and to the first control lamella. The first adjustment element has a toothed segment, which is in engagement with a first gearwheel that is rotatably mounted on the housing. The first gearwheel is in engagement with a second adjustment element that is arranged on a second control lamella of the second lamellae, wherein the second control lamella is coupled with the other second lamellae by way of at least one connection rod, and the second gearwheel is of spring-mounted design.

Abstract: A device for controlling an air stream includes a control slat swivelly mounted in a housing and second slats extending orthogonally with respect to the control slat and swivelly mounted in the housing. The direction of the air stream exiting from the housing and the quantity of air streaming out can be set by the slats. An operating element is arranged orthogonally with respect to the longitudinal axis of the control slat to swivel and is coupled to a first bevel gear rotatably mounted on the bearing web and to the control slat. The first bevel gear is in engagement with a second bevel gear which is coupled to a lever arrangement which has at least one rotatably mounted first coupling member which is coupled to at least one first coupling rod and the at least one first coupling rod is coupled to the second slats.
