An medical device include a shaft having an elongated inner tubular member and an elongated tubular reinforcing member disposed over a portion of the inner tubular member. The weighting values are determined as a function of frequency based upon a state of a communication channel and the transmission mode of the signal. For example, the method may sequentially expose adjacent areas of semiconductor film to gated light in a first direction; and, simultaneously exposing adjacent areas of semiconductor film to gated light in a second direction, different than the first direction. Each output stage has one or more levels of cascoding including one or more thick oxide devices and one or more thin oxide devices. The sliding table contacts the driving arm.
