Embodiments for at least one method and apparatus of controlling a bypass resistance of a voltage regulator are disclosed. The internal retractor has a transverse dimension insertable through a cannula, and a longitudinal dimension deployable to retract user selectable organs. A welder, rotatably inserted into welded portions of the first and second pistons supported on the support, performs friction stir welding along the rotation direction of the first and second pistons. The sensing and writing circuit amplifies the bit of information and transmits it to the controlling device via the at least one IO bus. Thereafter, the user is notified, for example, with a distinct ring at the user’s telephone, of the option that the user may monitor and override the forwarded call.
