Abstract: Methods for detecting radar targets are provided. According to one exemplary embodiment, the method includes providing a digital radar signal having a sequence of signal segments. Each signal segment of the sequence is respectively associated with a chirp of a transmitted RF radar signal. The method further includes detecting one or more radar targets based on a first subsequence of successive signal segments of the sequence. For each detected radar target, a distance value and a velocity value are determined. If a group of radar targets having overlapping signal components has been detected, a respective spectral value is calculated for each radar target of the group of radar targets based on a second subsequence of the sequence of signal segments and further based on the velocity values ascertained for the group of radar targets.

Abstract: Methods for processing an OFDM radar signal are provided. A plurality of Nc×NDS receive samples corresponding to a number of NDS consecutive OFDM symbols is received, each OFDM symbol comprising a plurality of Nc subcarriers modulated with a respective modulation symbol. Each of the plurality of Nc×NDS receive samples is divided by its respective modulation symbol to generate a number of NDS processed OFDM symbols. The number of NDS processed OFDM symbols is decimated to generate at least one decimated OFDM symbol. A first type discrete Fourier transform (e.g. IFFT) of the at least one decimated OFDM symbol is performed to generate at least one first transformed vector.

Abstract: First, an auxiliary cut-out (11, 16) is formed in a side wall (1) of a continuous casting mold. That cut-out extends, in the longitudinal direction, at least over the cut-out length (L) of the useful cut-out (10) and has an auxiliary cross-section orthogonal to the longitudinal direction. Then, an additional element (13, 14, 17) is inserted into the auxiliary cut-out (11, 16), and extends, in the longitudinal direction, at least over a cut-out length (L) of a later useful cut-out (10) and bounds the useful cut-out (10) orthogonally to the longitudinal direction at least over part of the periphery of the useful cut-out. The useful cut-out (10) is formed by inserting the additional element (13, 14, 17) into the auxiliary cut-out (11, 16). The useful cut-out (10) is closed all around orthogonally to the longitudinal direction. Orthogonally to the longitudinal direction, the useful cut-out has a (correspondingly small) useful cross-section and a maximum useful extent (d3).

Abstract: A monitoring device (6) records variables that are characteristic of operating parameters of a continuous casting mold (1) for casting a metal strand (2). The monitoring device (6) records at least some of the characteristic variables by independently performing measurements during the casting of the metal strand (2). The monitoring device (6) forms groups (G1, G2) of operating parameters and independently tests whether the operating parameters of the respective group (G1, G2) satisfy a respective predetermined stability criterion. The monitoring device (6) accepts the operating parameters into a database (12). The monitoring device (6) determines those data records (11) contained in the database (12) that coincide in their input variables with the basic operating parameters and determines admissible operating parameter ranges for supplementary operating parameters.

Abstract: A method and an apparatus for automatically feeding printing plates to a rotary printing press include conveying devices spaced apart from each other transversely to a conveying direction for feeding the printing plate to a clamping device having register pins. One of the conveying devices is lifted briefly off the printing plate in the event of a lack of in-register contact while the other conveying device remains in contact with the printing plate and thus ensures a forward drive of the printing plate, while the lifting of one conveying device promotes stress relief in the printing plate. A sheetfed rotary printing press having the apparatus, is also provided.

Abstract: A method of depositing sheets coming out of a sheet-processing machine includes decelerating the sheets and depositing the sheets of a main pile. Certain sheets are decelerated and fed to a second sheet pile.

Abstract: A piston internal combustion engine with at least one gas exhaust valve (2) for each cylinder (1), which is actuated by an actuator (7), in particular an electromagnetic actuator, controlled by a fully variable engine control unit (15). Based on the predetermined operating cycle, the valve can close off the cylinder interior space against a gas exhaust channel (13) that follows the valve seat (3) of the exhaust valve. This channel is connected to an exhaust gas system and is provided with a means for example a constriction (14) for reducing the pressure gradient during the start of the opening of the gas exhaust valve (2). A specific pressure fluctuation is used for a further reduction in the pressure gradient behind the exhaust valves during the opening through a corresponding layout of the pipe geometry and the container volumes in the exhaust gas system or corresponding installed components.

Abstract: The increasing number of mobile battery-powered small appliances with different feed voltages and connecting devices is calling for a universal and compact energy supply apparatus which provides for an uncomplicated and at the same time cost-efficient adjustability to as many small appliances as possible. To this end, the present application proposes a universal power supply unit consisting of an energy station with an integrated voltage converter in combination with various appliance-specific adapter cables with a group of electronic components. This generates an individual programming signal in the adapter cable which when coupling the adapter cable to the energy station causes a corresponding setting of the required output values. This leads to a simple matching of the unit with various small appliances and provides for a large field of applications. In particular, by feeding solar energy the power supply unit may be rendered autarchic in terms of energy.
