Abstract: A method for the automated early detection of forest fires by means of the optical detection of clouds of smoke, includes the following steps: producing images by means of at least one digital color-image camera and transmitting said images to a digital data processing medium; defining membership functions in a fuzzy-logic system for the classes “smoke,” “forest,” and “dark surface” by evaluating a plurality of test images or test sequences recorded by the color-image camera with respect to the saturation value (S) of the image pixel.

Abstract: The invention relates to a brake disc having a brake disc pot (42) and a friction ring (10) which is positively connected to the brake disc pot via toothing (50). The friction ring (10) comprises two friction ring halves (12, 14), wherein the toothing extends across only one of the friction ring halves. In this manner it is possible to mount through-passages (30) axially adjacent to the toothing running around the friction ring half on the interior circumference of the friction ring, said passages connecting the interior circumference of the friction ring to an interior ventilation arrangement of the friction ring. In this manner both a good force transmission and a stable positive connection is ensured between the friction ring and the brake disc pot, as is an efficient cooling by means of an interior ventilation of the friction ring.

Abstract: The invention relates to a brake disk for a motor vehicle having a brake disc cup (10) and having a friction ring (18) supported thereby and made of a cast material, joined to each other by means of a joint connection, particularly a welded connection (32), wherein an intermediate component (20) is cast into the friction ring (18), by means of which the friction ring (18) is connected to the brake disk cup (10). The invention further relates to a method for producing such a brake disk.

Abstract: The invention relates to a disk brake, especially for a motor vehicle, comprising a wheel hub (10) and a friction ring (18), which are firmly interconnected radially by a form lock (24) and axially by at least one securing element (26). The invention is characterized in that the at least one axial securing element (26) is arranged in a receiving recess (38) which extends radially inside the friction ring (18), said friction ring (18) being radially movable relative to the securing element (26) in the area of the receiving recess (38).

Abstract: A device for a full-duplex-capable radio transmission system with DS-CDMA access, including a central radio base station, and a plurality of subscriber stations which are independent of one another and which are each designed with at least one transmission and reception antenna, the radio base station having a reception antenna divided in its horizontal antenna characteristic into a plurality of reception segments, and an evaluation unit connected to the reception segments and operative to determine which of the reception segments has the best reception quality on a subscriber-specific basis and to select the determined reception segment for further data processing, the radio base station further including a transmission antenna having a segmented antenna characteristic.

Abstract: A method is proposed for assembling micromechanical sensors, in particular Hall sensors, or pressure or acceleration sensors, in which at least one silicon sensor element is applied to a substrate. The at least one silicon sensor element is joined to the substrate via at least one assembly pedestal, the cap faces of which are kept small compared with the surface of the silicon sensor element, so that a gap exists between the substrate and the silicon sensor element except for the region of the at least one assembly pedestal.

Abstract: A frequency divider circuit and variants thereof, intended for use with the fuel injection system of an internal combustion engine. The primary trigger signal is one derived from a rotating engine member and this signal is used to generate two input pulse trains of opposite relative phase. A basic dividing block includes two bistable multivibrators formed by gates with crossed feedback. The inputs to these multivibrators are provided by two-input gates and the input pulse trains are applied, respectively, to the input gates ahead of the first and second multivibrators. The second inputs of the input gates receive the direct or crossed-over outputs of the multivibrators. Additional circuitry is disclosed for providing odd dividing ratios, e.g. 1:3.
