According to the invention, the complementary logic function to the prior art is replaced by a single transistor appropriately sized to provide the complementary output OUTBAR.

If the 21st century is the ‘individual age’, then the right approach is not a binary logic, that defines itself in opposition to something, but a complementary logic that connects differences.

A wireless mobile phone (100) is provided with one or more buttons (102) and complementary logic to facilitate entry of encoded representations of a varaible length encoding scheme of alphanumeric data.

The character has at least one additional non-data bit position that has a first logic signal for the initial character of a message and the complementary logic signal for the remaining characters in the message.

These circuitry and complementary logic support a hierarchical view of the serial bus elements (16), logically dividing the hierarchy into multiple tiers.
