A Multi-Level Cell memory device and method thereof are provided. The driver circuit has a current generator that is in series with the transmitter, and a current robbing circuit is coupled to the transmitter. The hollow nano-tube structure facilitates salt dissociation, serves temporarily storage for lithium ions, creates new conducting mechanism and improves the conductivity thereof. The detecting mechanism is disposed in an adjacent relationship with the mechanism for providing an internal anatomic image so that the body part remains in the same position during and between anatomic and radiotracer imaging. More particularly, the first gear is prevented from rotating with a cam mechanism associated with the pulley causing the translation of the first gear and, once the first and second gears become so engaged, the first gear can rotate with the pulley.
