  • Patent number: 5489982
    Abstract: A method for determining the visual range improves the visual range measurement adopted as a basis, to the end that the measurement of the visual range can take place using one emitter and using one receiver, which are disposed to be stationary. The method permits the determination of the visual range, even though an obstacle is situated within the field of view. A comparison of a measured backscatter signal with a specimen curve permits the determination of the visual range from the intensity curve obtained, without any need, for this purpose, of further information such as, for example, the direction from which the backscatter signal comes.

  • Patent number: 5410304
    Abstract: A method for displaying the impending danger due to speed associated with the driving situation of a vehicle and a display appliance for carrying out the method are described. In accordance with the method, a degree of danger is defined and calculated and displayed to the driver of a vehicle and, in fact, independently of whether the vehicle, as following vehicle, is driving too close to a vehicle in front or other obstacle (distance problem) or is driving too fast in fog (visual range problem). The signals necessary for this purpose are obtained from vehicle environment sensors, for example from a distance warning radar or distance recording radar and an infrared visual range measuring system, and are analyzed, together with vehicle condition signals, by a safety computer.

  • Patent number: 3994532
    Abstract: An apparatus for the pneumatic discharge of containers which are lined with a foil bag which contains a pulverulent mass comprises a tubular connection to the container having an interior sleeve portion opening into the container and providing a rotatable support for a double walled suction tube. The double walled suction tube has an interior end with a central opening into the container and an annular opening which communicates with the space between the walls and which is supplied with an air for the purpose of breaking up the pulverulent mass at the entrance to the central suction. Additional air is supplied through openings in the sleeve to the space surrounding the suction tube and the sleeve advantageously includes an insert at its inner end forming a nozzle-like divergent sections with a flow of air into the container to support the bag against collapse.
