1. A data entry and decoding system comprising:
- a surface divided into a plurality of discrete electrically conducting zones electrically insulated from one another, an electric contact device for transmitting electric signals to said zones as said electric contact device is moved over said surface in a path forming a data character;
logic circuit means connected to said zones for generating a sequence of multi-bit combinations of signals, each multi-bit combination of signals representing a zone contacted by said contact device as said contact device is moved over said surface to form said data character, and the position of each multi-bit combination in said sequence corresponding to the sequence in which said zones are contacted;
storing means responsive to said logic circuit means and having means for storing said multi-bit combinations of signals in accordance with the sequence in which they are generated; and
decoder means responsive to said storage means for generating a pattern of signals representing said data character.

Abstract
A conductive stylus is utilized in conjunction with conductive segments torovide for data entry into extremely small calculators such as might be incorporated in an electronic digital watch case. Multi-bit codes, representing the segments contacted by the stylus, are generated and stored as the stylus moves over the segments. These codes are stored until a complete character has been scribed. The stored multi-bit codes are then analyzed in accordance with the segments contacted and the sequence in which they were contacted to determine what character was scribed.
