Abstract: A system and control method for embossed-in-register of a sheet is provided. The system comprises a printed film winding/releasing mechanism, a film laminating roller and a pattern roller spaced from the film laminating roller, wherein the printed film is provided with first identifiers at intervals, and the pattern roller is provided with second identifiers at intervals; the system further comprises: a color code sensing mechanism configured to detect the first identifiers, an encoder configured to detect a rotation position of the pattern roller, and a control system; the control system comprises a storage unit, a data acquisition unit and a control unit; wherein, the control unit is configured to calculate a deviation of a pattern position, corresponding to a current first identifier, of the printed film and a pattern position, corresponding to a current second identifier, of the pattern roller in a same pattern, and generating a control signal of the pattern roller based on the deviation.

Abstract: A method and system for managing IPv6 address conflict automatically are provided. The method comprises: after receiving a DAD message of a terminal, a BRAS searching local records to judge whether there is an interface identifier in the DAD message under a prefix which is the same with a local routing prefix in the DAD message, and if yes, then transmitting a reconfiguration message to the terminal; otherwise, then recording the interface identifier.
