Some embodiments of the present invention provide methods of operating an electronic device, such as a wireless communications terminal, a personal digital assistant andor a media player, having a personal information manager, such as a scheduling application andor a contact management application. The porous or microporous separator laminate may be a single polymer layer or a multiple polymer layer. The sign metric may specify an error associated with the plurality of TPC bits. The extension of the technique to swivel head mill-turn machines is also described. The architecture includes the following components: an input isolation block, an analog voltage divider, an input comparator, a sampling latch, a current control counter, and a bitwise output driver. The sales representative is then credited with the sale.
