A track for track-type vehicles is described, comprising a continuous sequence of articulated joints of the hinge type, oriented according to a first axis substantially perpendicular to the central longitudinal development axis of the track. Currents are sensed through induction of voltages in an electrically-isolated coil mounted directly to the rails. For example, there may be three options. If the tumor extends too close to the circular incision, the cannula may be rotated so that its sidewall opening faces the side of the remaining tissue to be excised and the surgeon can pull the remaining tissue through the sidewall and excise it, thereby avoiding a separate and delayed surgical procedure. A column address strobe latency control multiplexer selects the output enable signal corresponding to column address strobe latency among the plurality of output enable signals, on the basis of the signal obtained by delaying the input signal by the phase difference between the clock and the delay locked loop clock, and outputs the selected signal as the data output control signal.
