A device for processing a data stream originating from a device generating matrices of Nl rows by Nc columns of data includes K computation tiles and interconnection means for transferring the data stream between the computation tiles. Two cams, having openings for the spindle, bush pin and fastening bolt, are aligned with the bracket bores. The method also includes receiving buffer control header with a data packet of a second stream. The covering layer is placed around an outlet opening of the nozzle hole. In other aspects, an electrical module includes at least one of these electrical connectors. A condition of the value document is determined for the condition value using a preset criterion.
