An intermediate voltage is maintained between a first voltage and a second voltage by conditionally or selectively performing data bus inversion andor data swap operations on a first and second transmit channel. A driveshaft rotates the first cable reel and the second cable reel. In some embodiments, the die includes a defined recess that contains and centers the blank on the die as the blank is fed to the die. The technique includes receiving, at the server, position information from a mobile phone associated with the user indicating the user crossed a geo-fence corresponding to a specific location of a specific one of the one or more phones.
