A device for realizing upstream aggregation and downstream translation of a virtual local area network includes a buffer and a processor. The method is realized with the use of a tape of a porous structuring material that may be dry or impregnated with a liquid having a freezing point above the temperature of a cryogenic fluid in the pipeline. The approach also involves causing, at least in part, the preamble sequence to be divided into a predetermined number of blocks. Each block contains sufficient texture information such that the transformed texture retains the continuity of visual properties, such as shape, size, and color, of the image texture sample. A torsional spring is located between the rigid region and the mounting region.
