Abstract: The present invention discloses a method and apparatus for providing very fast message synchronization of synchronous serial data streams by reducing system reliance on complex and highly computational synchronization schemes. The benefits of the instant invention are realized by performing most of the computational effort during message design, rather than during real-time detection. The synchronization pattern preceding the data stream is constructed in accordance with predetermined rules and compared using multiple bit segment compares rather than performing comparisons bit-by-bit. The synchronization pattern is further provided with an index that is used to access a lookup table that contains information for providing true alignment of the data stream once synchronization has been detected.

Abstract: A computerized press control includes a set of counters countable in real time as the associated press cylinder rotates to enable the press control system to readjust the inspection zone, wherein the mark to be sensed on the web can be expected to be found, on a per revolution basis of that cylinder and to dynamically alter the length of the inspection window on a per revolution basis to enable the press control system to control color registration in spite of wide variations in press speed or conditions of the web.
