Abstract:
A water lance blower for cleaning heating installations, wherein a water lance (6) is movably (5) arranged with its mouth on or in a hatch (2) and can blow a water jet through the heating installation, which is in operation and is flowed through with flames and/or smoke, onto wall areas (A-E) which can be reached from the hatch (2), wherein the water lance (6) is movable by at least one movement element (8.1, 8.2, 8.3) which is stationarily fixed at one end outside a vertical plane through the point of movement (5) of the water lance (6) to the heating installation and by the other end (7.1, 7.2, 7.3) to the water lance (6), wherein path sensors are provided for precise determination of the position of the water lance (6). Preferably three movement elements (8.1, 8.2, 8.3) are provided, the fixing points (9.1, 9.2, 9.3) of which each form in particular an angle of approximately 80° to 140° to the point of movement (5) of the water lance (6). Such water lance blowers can be installed even when there are unfavorable spatial conditions and perform any freely pre-determinable blowing patterns and speed profiles.
Abstract:
A method for determining an item of control information for displaying a driving condition of a vehicle with the aid of a display unit includes: an ascertainment of the safe driving condition of the vehicle, in which no risk of a collision with an object exists; an ascertainment of a prevailing driving condition of the vehicle in relation to the safe driving condition is carried out; a determination of the item of control information for activating the display unit based on the safe driving condition and the prevailing driving condition, the item of control information causing a display of an item of information about the prevailing driving condition in relation to an item of information about the safe driving condition by the display unit.
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 machine tool, in particular a circular table saw, having a tool holding fixture, in particular for a disk-shaped, rotary-drivable tool, and a protective device. The protective device may be provided for the purpose of guiding the tool into a safety position, and from the safety position into at least one working position.
Abstract:
A circular saw including a saw blade (36) which may be rotatingly driven about a rotational axis, and at least one first splitting wedge is described. The circular saw is configured so that the first splitting wedge is movable relative to the rotational axis of the saw blade.
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 positioning of a controllable blower lance for cleaning a pre-determinable surface of a heatable internal chamber, preferably a combustion chamber, in which deposits form, wherein at least one site of impact of a cleaning medium of the blower lance on a surface to be cleaned of the internal chamber and at least one position of at least a part of the blower lance, by means of which the direction of flow of the cleaning medium out of the blower lance can be determined, are established and recorded and a correlation is established between at least the site of impact and the position, taking into account at least one parameter concerning the internal chamber, wherein by means of the correlation, the positioning of the blower lance can be determined for cleaning the pre-determinable surface. Furthermore a method and a device are provided for cleaning an internal chamber, preferably of a combustion chamber in which deposits form, with a controllable blower lance, the cleaning medium of which must strike a pre-determinable surface to be cleaned of the internal chamber, wherein a pre-determinable control system of the blower lance is superimposed with a correlation associated with the condition in the internal chamber and/or the condition of the cleaning medium, such that the pre-determinable surface to be cleaned is struck according to plan by the cleaning medium whatever the conditions in the internal chamber. Undesired shifting of the cleaning jet of a blower lance, caused by different operating conditions in the internal chamber, can be compensated for in this way.
Abstract:
A method for recognizing directional structures on a window pane of a vehicle is described. The method includes carrying out an assessment of image points of an image of the window pane, which image points are disposed along an evaluation path, a course of the evaluation path being dependent on an expected orientation of the directional structures on the window pane. The method further includes recognizing a directional structure based on the assessment.
Abstract:
A method for ascertaining image signals having color values and a camera set-up, which has: a camera having camera optics, an image sensor for recording an environment and for outputting first image signals, and a color mask applied in front of the image sensor, and an evaluation device, which picks up the first image signals emitted by the image sensor, the image sensor having a plurality of sensor pixels and the color mask having a plurality of filter pixels which are each situated in front of the sensor pixels and include first colored filter pixels and transparent filter pixels; and some of the sensor pixels picking up the light via the colored filter pixels and outputting the first color values, and additional sensor pixels picking up the light via the transparent filter pixels and outputting the intensity values. The evaluation device ascertains second color values from the intensity values and the first color values of various sensor pixels, and forms second image signals from the first color values and the second color values.
