Method and system for providing data transmission with transparency over the Gigabit Ethernet data stream includes receiving the 10 bit code with a data rate of 1,250 Mbitssecond from the encoded 8B10B data and arbitrarily selecting 9 bit codes using a look-up translation table which can fully represent the 10 bit codes received. A scanner is described which acquires images of the dentition which are converted to three-dimensional frames of data. If the time t2 is later than the time T1, a transportation command for transporting the article to a buffer on the upstream side of the load port is assigned.
