A rewinder having a first winding roll that transports and supports the web, at least one core support plate that is curved for receiving and guiding cores adjacent the first winding roll, and a web separator adjacent the first winding roll and movable into pressing relationship with the web at a velocity at least equal to that of the web. A first diode and a second diode are connected in series, the anode of the series connected to the IO pad and the cathode connected to the power pad. The device includes first-stage correlators taking correlation between M received signals and M spread code sequences obtained on decimating a spread code sequence of a length N, and a second stage correlators taking correlation between the correlation values associated with K signatures output by the first-stage correlators and a pre-defined signature pattern. For example, the adjustable component may be adjusted longitudinally with respect to the axis of the nozzle or rotationally using the tool, thereby increasing or decreasing the volume, velocity and distance of the water stream exiting the nozzle. Accordingly, multiplexing a single instance of the wide range amplitude detector andor multiplexing multiple instances of the wide range amplitude detector may result in reduced design time, reduced circuit size, andor reduced cost. Six embodiments of the implant are shown along with three embodiments for a vertebral distractor and reamer guide.
