Abstract: A material processing unit has a movable tool accommodated in a housing. The housing includes a housing part which can be moved between an open position and a closed position relative to a further housing part. A safety device prevents any opening of the housing when the tool is driven and/or prevents any driving in the open position. The safety device includes at least two actuators and a controller. A first actuator locks the housing part in the closed position. A second actuator causes, supports and/or permits a movement of the housing part. Sensors are assigned to the actuators. A controller is designed to control the drive and the actuators and to receive the actuation states detected by the sensors. A method for opening/closing a housing of a material processing unit is also provided.

Abstract: The invention relates to a crusher unit (10), in particular an impact crusher, having an impact rotor (11), having at least one swivel-mounted impact rocker (20), wherein a crushing gap (15) is formed between the impact rotor (11) and the impact rocker (20), wherein the impact rocker (20) can be swiveled along an adjustment path by means of at least one gap-adjusting means (30) to set a gap width of the crushing gap (15), wherein the impact rocker (20) is mounted such that its weight force acts in the direction of a reduction of the crushing gap (15). For a high degree of operational safety, the crushing gap can be readjusted during operation in that at least one retaining device (50) is provided, which uses a retaining force to flexibly counteract a swiveling of the impact rocker (20) in the direction of the impact rotor (11). The invention also relates to a method for setting the crushing gap (15) of a crusher unit (10).

Abstract: The invention relates to a material processing device (1), in particular a mobile material processing device (1), having a conveyor device (10), in particular a conveyor belt, for conveying processed material and/or material to be processed in a direction of conveyance (FR) between a pick-up area (13) and a discharge area (16) of the conveyor device (10), wherein the conveyor device (10) has a first and a second conveying area (11, 12), wherein the first conveying area (11) is coupled to the material processing device (1) in the area of a first connection (15) such that it can swivel about a first joint having a first swivel axis (15.

Abstract: A driver assistance system (1) for a vehicle includes environment sensors (2), which sense a vehicle environment of the vehicle, and a data processing unit (4), which evaluates sensor data of the environment sensors (2) to detect obstacles (H) in the vehicle environment. In accordance with detected obstacles (H), concealed regions (VB) in the vehicle environment of the vehicle are determined, which concealed regions are concealed by the obstacles (H) and restrict a field of view (FOV) of optical environment sensors (2) of the driver assistance system (1).

Abstract: The invention relates to a method and a device for displaying an image of the surroundings of a combination of two vehicles that are coupled to one another. According to the invention, image data is sensed by sensors on both of the combined vehicles. Taking into account the three-dimensional position of the vehicles relative to one another, the image data is then combined so as to obtain a common image of the surroundings. The obtained common image of the surroundings allows a driver/operator to efficiently and safely perceive the surroundings around the entire vehicle combination.

Abstract: A camera surround view system for a vehicle includes at least one vehicle camera that supplies camera images processed by a data processing unit to generate an image of the surroundings. The image of the surroundings being displayed on a display unit. The data processing unit re-projects textures, which are detected by the vehicle cameras, on an adaptive re-projection surface, which is similar to the area surrounding the vehicle, the re-projection surface being calculated based on sensor data provided by vehicle sensors. The data processing unit adapts the re-projection surface depending on a position and an orientation of a virtual camera.
