Abstract: A motor vehicle with a chassis which has at least two axles. A subframe is associated with one of the axles and is connected to the chassis and on which the at least two wheels of the respective axle are each mounted and held by way of a single-wheel suspension, and with at least one bearing device for elastically connecting the subframe to the chassis, which permits relative movements between the subframe and the chassis. A balancing between comfort and performance can be improved with at least one connection device for rigidly connecting the subframe to the chassis, which is switchable between an open state in which the connection device permits relative movements between the subframe and the chassis, and a closed state in which the connection device prevents relative movements between the subframe and the chassis.

Abstract: Pattern transfer sheets, methods of monitoring pattern transfer printing, and pattern transfer printing systems are provided, for monitoring and adjusting laser illumination used for transferring paste patterns from trenches on the sheets onto a substrate such as electronic circuitry and/or solar cell substrates. Pattern transfer sheets comprise, outside the pattern, (i) trace mark(s) configured to receive the printing paste, aligned to the trenches and are wider than the width of the illuminating laser beam—to detect misalignment of paste release from within the trace mark(s) and/or (ii) working window marks configured to receive the printing paste, set at specified offsets with respect to specific trenches, with different working window marks set at different offsets—to correct the effective working window by adjusting the power of the laser beam.
