Abstract: Various embodiments of the disclosure include methods for testing measuring devices n for resources of an energy system assigned to a common measuring device. The method may include: acquiring a measurement signal Pn(t) by way of each of the measuring devices n; acquiring a sum signal PPCC(t) by way of the common measuring device; providing an objective function Z, which defines a difference between the acquired sum signal PPCC(t) and a modeled sum signal {circumflex over (P)}PCC(t), wherein the modeled sum signal {circumflex over (P)}PCC(t) is formed by way of the acquired measurement signals Pn(t) and a respective scaling factor Sn; and computing the values of the scaling factors Sn by extremizing the objective function Z. The test includes determining an error with one of the measuring devices n through a deviation of the computed value of the associated scaling factor Sn from a value defined for the respective measuring device n.

Abstract: In the present embodiments, a statement related to an image point or an image region in a reconstructed x-ray image is made in relation to the reliability of the reconstructed grayscale value for the image points of a 2D/3D x-ray image. A confidence level is formed for the grayscale value from a first number of the available x-ray images in relation to a second number of required x-ray images for a complete reconstruction of the respective grayscale value of the 2D/3D x-ray image to be imaged.

Abstract: In a method and an apparatus for representing an x-ray image of an examination subject, a measurement field is determined in the image field of the x-ray image, the measurement field being dependent on the position of a subject image region representing the examination subject in the image field and being essentially situated within this subject image region grey scale values for the image rendering are determined exclusively from the intensities measured within this measurement field.

Abstract: A motor vehicle front end and a method for producing a motor vehicle front end are provided in accordance with embodiments of the invention. The motor vehicle front end has a front wall and the front wall girder, the front wall girder essentially being situated in the direction of a vehicle transverse axis. In addition, the motor vehicle front end has a first front wall girder, the first front wall girder being situated essentially in the direction of a vehicle vertical axis. The first front wall girder is supported on the front wall crossbeam in a first area of the front wall crossbeam.

Abstract: In a method and an apparatus for generation of an x-ray image of an examination subject, a subject image region exclusively reproducing the examination subject is identified in the image field of a first, complete x-ray image. A grayscale value range is identified in an intermediate image encompassing the entire image field and derived from the first x-ray image by digital image processing; and all image points whose grayscale value in the intermediate image lie within this grayscale value range are associated with the subject image region.
