Abstract: A method for operating a brake system. A brake request signal characterizing a brake request is generated by actuating a positioner system of an actuating circuit, and a setpoint brake pressure required in an active circuit is ascertained based on the brake request signal. An actual brake pressure is set in the active circuit according to the setpoint brake pressure using a pressure generation device by moving a displacement piston using an electric motor to actuate a wheel brake coupled with the active circuit. Under the condition that the brake request signal is constant over a predefined period of time, a pressure modulation is carried out, which includes setting the actual brake pressure in the active circuit to a value that is greater than the setpoint brake pressure, and lowering the actual brake pressure by moving the displacement piston using the electric motor until the setpoint brake pressure is reached.

Abstract: The invention identifies plants carrying certain mutations, which can be used as haploid inducers or doubled haploid inducers in plant breeding. According to the invention, significant haploid induction and even doubled haploid induction rates can be observed when at least one functional mutation within a SAD-homology domain is present, wherein the functional mutation affects the expression of certain SAD-homology consensus sequences. The present invention further provides haploid and doubled haploid plants, which are obtained by contacting a first gamete from a plant as identified according to the invention with a second gamete from a plant expressing a wild-type SAD-homology domain to generate a zygote. Furthermore, the present invention relates to a method for identifying a plant having the activity of a haploid inducer or a doubled haploid inducer in a plant population.

Abstract: The production of noble metal oxalate complexes from noble metal precursors and oxalic acid and/or oxalic acid salts is an exothermic reaction, in which heat and CO2 are produced, is described. The temperature can increase above the decomposition point of the noble metal oxalate complexes in the course of the reaction, which simultaneously releases more CO2. For safety reasons, when the reaction is carried out on a large scale, it is therefore necessary to take into consideration that the product must not be decomposed by heat that is produced during the reaction. Therefore, according to the invention, a method for the production of noble metal oxalate complexes is provided, in which the product noble metal oxalate complexes are added to the reaction mixture as an auto-catalyst.

Abstract: A device for recognizing the angular position of a rotating part is described in which the rotating part is a pick-up disc (14) provided with a multiplicity of regular angle marks (11) and a distinguishable reference mark (12), which is formed, for example, by two missing angle marks (11). The number of angle marks is (n-2), where n is a number which is divisible by as many numbers as possible corresponding to different numbers of cylinders and, for example, is 36. The voltage sequence generated in the sensor (15) is analyzed in the control unit (19), unambiguous cylinder recognition being obtained after the recognition of the reference mark (12) by comparison with a camshaft signal. The analysis of the voltage sequence also supplies the rotational speed and flanks, which can be predetermined, of the pulse sequence used for ignition and/or injection control.

Abstract: The invention relates to ignition circuit monitoring in an internal combustion engine, where a sensor signal is generated in the course of each ignition by an ignition current sensor (5), which is supplied via a pulse shaper (6) to a memory unit (7). An ignition computer (4) reads out the contents of the memory following each ignition or each sensor signal and resets the memory unit (7) prior to the next ignition. Thus, when the sensor signal is missing, the ignition computer (4) detects the lack of ignition and an appropriate control signal is made available for control actions.
