Modular fluidic microchips, systems integrating such microchips, and associated preparative and analytical methods are presented. Each of the planetary gear sets includes first, second and third members. By exposing the portions of the base electrodes on the peripheral surfaces and whole base electrodes on the end surfaces, the contact strength between the base electrodes and the terminal electrodes can be substantially increased. The method further includes placing a value in the virtual network identifier field identifying the virtual network associated with the data frame and transmitting the data frame over the shared communications medium. There is also provided a method of fabricating an OLED capable of controlling static electricity when an organic layer is formed using an laser induced thermal imaging method, since the donor substrate having a conductive layer is electrically connected to an earthed stage.
