An insert for receiving a bone screw includes an elongate sleeve having opposed proximal and distal ends and a wall defined by an outer peripheral surface configured for engaging bone and an inner peripheral surface configured for receiving a bone screw extended therethrough. In a medium that recordsplays back data including video data and control information, the control information includes information for accessing a specific portion of the video data. More particularly, the visual gauge will take the form of a table or listing that shows a continuum of possible time-increment or data-increment-ranges and that shows, for each range, the associated cost. The taps and corresponding fine stage switches are arranged into two or more groups, where each group has n-number of fine stage switches and corresponding taps. The belt spool is rotatable to a limited extent with respect to the drive wheel and a sensor is provided that on rotation of the belt spool relative to the drive wheel generates a signal which is representative of the belt force acting in the safety belt and is supplied to the electronic control unit.
