A system and method is provided for attenuating a light signal. The pixel array includes scan lines, signal lines, pixels, and auxiliary scan lines. Thereafter, a portion of log segments are replayed up to a specified position while skipping at least one portion of the log prior to the specified position that is identified by the at least one log hole. A term generally is important and remains part of the profile as long as its weight and the weight of the next term may be differentiated. Optionally, the signal modules may include vias having conductive liners therethrough that electrically connect ground planes from opposite sides of a signal module to one another.
