The present invention is directed to compositions, methods of use, and processes for the synthesis related to 3–1-ethyl)phenyl methyl–1-phenylpropan-2 yl)carbamate, and its pharmaceutically acceptable salt forms, including the hydrogen fumarate salt. An error amplifier adjusts the gate voltage of the output transistor such that the voltage that corresponds to the output voltage approaches a predetermined reference voltage. Also provided are methods of using the transdermal compositions and kits containing the transdermal compositions. The saved relevant information is displayed on a report window. The data wiring is formed on the gate insulating layer and includes a data line, source and drain electrodes.
