Abstract: A computer-implemented method is for determining at least one main acquisition parameter determining a dose of x-rays to be emitted from an x-ray emitter during image acquisition using an x-ray emitter and an x-ray detector. A first image data of a first preparatory image is evaluated to determine if a repeat condition is fulfilled and/or to determine the main acquisition parameter and/or at least one second preparatory acquisition parameter. The first preparatory image is acquired by the x-ray detector using at least one first preparatory acquisition parameter to control the x-ray emitter. In all cases or when the repeat condition is fulfilled, the main acquisition parameter is determined depending on second image data of a second preparatory image, acquired by the x-ray detector after the first preparatory image while at least one second preparatory acquisition parameter is used to control the x-ray emitter.

Abstract: A windshield wiper structure includes a supporting member, a connection bracket straddled on a predetermined surface of the supporting member, and a wiper strip engaged with the supporting member. The supporting member includes two elongated arc sheets parallel to each other. The connection bracket has a base, two parallel plates extending upwardly from two lateral sides of the base respectively, a bar over the base and connected between the two parallel plates, and a clip member extending inwardly from each lateral side of a bottom of the base in order to clasp the lower surface of the supporting member.
