Abstract: An adjusting device for fastening an operating and/or display device on a wall, having a linear guide arrangement formed by a sliding element and a fastening element, wherein the sliding element has an attachment point for the operating and/or display device. A secure support of the operating/display element results if the fastening element or the sliding element has a pivotable seating arrangement or hinge, with a pivot axis oriented parallel with respect to the displacement direction of the linear guide arrangement. The fastening element can be supported on the wall on two supporting points, which are spaced apart in the displacement direction of the linear guide arrangement.

Abstract: A clock generator system is provided which includes several clock generators each containing a feedback shift register. A parity bit is calculated over the output of all shift registers and compared to an expected value. Additionally, a parity bit is calculated for each shift register, over the bits stored in the shift register, the number of ONE bits in a shift register being constant. A parity error at the output of the shift registers in combination with an error in the additional parity bit allows the correction of the erroneous clock pulse generated by the shift register in error.
