A method is provided for forming at least three devices with different gate oxide thicknesses and different associated operating voltages, in the same integrated circuit device. A conduit support apparatus of embodiments may include a gravity-driven pulley support system. The mounting structure includes a transverse bar and the interface structure includes a portion that engages and mates with the transverse bar to form a rigid connection between the interface structure and the transverse bar. If both the valid and invalid bytes are present, the invalid byte is dropped and a valid byte from a succeeding data packet is concatenated with the valid byte of the first data packet, and byte shifting occurs in the succeeding data packet.
