According to one aspect of the invention, a method is provided in which a connection is established, via a first wireless network, between a first wireless device located at a first location and a diagnostic control unit located at a second location. In some embodiments, such a method is used for a router that partitions the region into a plurality of sub-regions. Based upon the information, the vector decoding section selects code-book vectors that represent the luminance signal and color-difference signals, and reconstructs the respective blocks. The testing may be performed for quality assurance after assembly or repair, or to determine the reliability of the device such as by testing the device until a particular life cycle value is reached or a component in the device fails. Rotation of the fiber bundle increases the relative velocity between the fluid and the hollow fibers and increases the mass transfer.
