Abstract: A method for detecting an interfering object in a camera image of a camera image sequence includes: reading in a first pixel data value of a predetermined position in a first camera image obtained at a first point in time, a second pixel data value of the predetermined position in a second camera image obtained at a second point in time after the first point in time, and a third pixel data value of the predetermined position in a third camera image obtained at a third point in time after the second point in time; ascertaining a reference value on the basis of the second pixel data value and a comparison value on the basis of the first pixel data value and/or the third pixel data value; and detecting the interfering object at the predetermined position when the reference value is in a predefined relationship with the comparison value.

Abstract: A method for assisting a user of a vehicle, in which driving-condition variables (v, a, q, ?, n) are sensed or ascertained via sensors of the vehicle, and a camera of the vehicle covers a coverage area of a road scene at least in front of the vehicle and outputs image signals. Based on the image signals, it is determined whether a further vehicle which is outputting blinking signals is in the coverage area. As a function of the ascertained driving-condition variables (v, a, q, ?, n) of the vehicle and as a function of the determination as to whether other vehicles are indicating a change of direction, information signals, particularly warning signals, are able to be output to the user and/or an automatic driver-assistance control is able to be implemented in which control signals for interventions in a vehicle control for a longitudinal control and/or lateral control, especially a distance control, are output.

Abstract: Classification methods are described that proceed in computer-assisted fashion, and in particular a method for evaluation and stabilization over time of classification results is described in which objects to be classified are sensed using sensors over a period of time, and are repeatedly classified with the inclusion of specific quality parameters for each object class. To ensure better classification reliability, the following steps may be carried out: a) increasing the value of the confidence parameter if a subsequent classification confirms the result of a previous classification; b) decreasing the value of the confidence parameter if a subsequent classification does not confirm the result of a previous classification; and c) generating a final classification result including the confidence parameters that have been increased or decreased in value.

Abstract: In a method for displaying an image of a scene in front of a vehicle, recorded by a video camera, in which the scene in front of the vehicle contains a roadway which is illuminated by the vehicle's headlights, the gray values of the pixels of the image data generated by the video camera are weighted using a reduction factor, which is a function of the respective pixel within the image and of the brightness of objects in the near range in front of the vehicle, in such a way that the contrast between the display of the near range in front of the vehicle and the display of other parts of the image is reduced.

Abstract: A method for determining an accident risk of a first object with at least one second object is proposed, a collision probability and a hazard probability of the at least one second object being determined in a predefined region around the first object, the collision probability and the hazard probability being determined as a function of motions and object classes of the first and the at least one second object. The accident risk is then determined as a function of the collision probability and the hazard probability.

Abstract: A method for controlling the drive-off of a motor vehicle in which the area in front of the vehicle is sensed using a sensor device and a drive-off enabling signal is automatically output after the vehicle stops, if the traffic situation allows. Features of the road in the area in front of the vehicle are extracted from the data of the sensor device, and on the basis of these features, at least one enable criterion is checked, a positive result indicating that the road is clear.

The control unit receives a signal about the prevailing activation state and/or availability state from the lane keeping system.

Abstract: A measuring device for a heat exchanger includes a heat exchanger pressure pipe having a pipe wall with a circumference, and an indentation extending over and deforming a portion of the circumference. At least one thermocouple is disposed eccentrically in the portion of the circumference deformed by the indentation. Filling material fills the indentation.

The size of the indentation can be decreased for a given size of the thermocouple due to the eccentric configuration of the thermocouple, so that the heat flux is obstructed to a comparatively small degree by the pipe wall while local overheating of the pipe wall is prevented.

Abstract: A bearing system for a water lance of a water lance blower contains a ball joint having a ball with a surface and a diameter. The ball further has a passage, on and/or in which the water lance can be disposed. The bearing system is characterized in that a ball seat is provided and contains two axially interspaced bearing shells each of which has an opening, whereby the ball protrudes at least partially into the openings. A method for operating the bearing system that seals gaps, which can occur as the ball rotates, between the surface of the ball and the spherical contact surface of the at least one bearing shell. The bearing shells enable the bearing system to be easily assembled, and the small contact surfaces reduce the amount of friction during operation. In addition, the bearing system is also suited for use as a seal.

Abstract: A water lance blower for cleaning heat installations is disclosed. A water lance linked with a water feed conduit system is swivel-mounted with its orifice disposed in a hatch. The water lance can blow a jet of water through the heating installation in operation and through which flames and/or flue gases are guided to wall areas that can be reached from the hatch. The water lance blower is provided with a drive system with at least two drive units that control the water lance, and with a holding device that fastens the water lance blower onto the heating installation. Further, parts of the water feed conduit system are integrated onto the holding device, thereby substantially limiting the size of the water lance blower to the swivel range of the water lance.
