Abstract:
1. A character input process comprising the steps of: providing a substrate, providing and affixing to said substrate at least one wireless energy transmission circuit, providing and affixing to said substrate a plurality of switchable RF contacts including a first switchable RF contact in a first state in a first physical position on said substrate, a second switchable RF contact in a first state in a second physical position on said substrate, a third switchable RF contact in a first state in a third physical position on said substrate, and a fourth switchable RF contact in a first state in a fourth physical position on said substrate, providing a memory, storing in said memory one selected from the group consisting of: a plurality of modulation patterns, a plurality of wireless transmission signatures, and a positional attribute of the physical locations of the switchable RF contacts on said substrate, storing in said memory a plurality of characters selected from the group consisting of: character meanings, character maps, character images, character shape attributes, and character modulation patterns, providing a wireless energy sensor wherein said wireless energy sensor is in wireless communication with said energy transmission circuit and said wireless energy sensor is in communication with said memory, wherein at least a single character is printed on said substrate, thereby altering at least said first switchable RF contact from said first state to a second state and said second switchable RF contact from said first state to a second state, wherein at least two of said plurality of switchable RF contacts are sensed by said wireless energy sensor, thereby sensing a state status of one from the group consisting of: said RF contacts that are in said first contact state, said the RF contacts that are in the said second contact state, utilizing said sensed contact states of at least two RF contacts to assign a character meaning to the printed input.
