A counterpoise device for cantilevering at least one cylinder of a printing press has a movable counterpoise element for selectively contacting the cylinder and a stationary mount. The diffraction grating includes grating patterns with a nonuniform period or phase. For the hybrid scheme, a user equipment may be assigned different resource blocks in different transmission intervals based on a hopping pattern. Further, the processes of determining the threshold and reading out the side edge position are executed after driving of the registration roller pair is resumed. The web server then distributes the picture of the face and the metadata to the identified gateways.
