Pilot transmission schemes suitable for use in wireless multi-carrier communication systems. During a set mode, a first and second floating gate are programmed to different charge levels that are a function of an input set voltage capacitively coupled to the first floating gate during the set mode. The apparatus determines a target-number of wavelengths for reducing a required number of transmission-systems. Thus, contamination and degradation of the liquid crystal can be avoided and further the two substrates can be conducted without using conductive material. In either case, the synchronization adapter makes the changes to the data, or performs a synchronization operation. A processor executes instructions from an application program module stored in the controller to perform a function of the configuration data for an electroluminescent device system selected from the multiple electroluminescent device systems in the internal electroluminescent device system configuration database.
