Abstract
A pattern recognition system includes an active media, an input system, and a sensing system. The active media is such that initial states respectively evolve over time to distinguishable final states. The input system establishes in the active media in an initial state corresponding to an input pattern, and the sensing system measures the media at separated locations to identify of which of the final states the media has after an evolution time. The identification of the final state indicates a feature of the input pattern.
Claims19
A pattern recognition system comprising:
- an active media having states that respectively evolve over time to a set of final states, wherein the active media has a characteristic that is fixed during an evolution time and varies across an area of the active media, and the final states are distinguishable according to activity in the active media at a plurality of separated locations of extrema in the characteristic;
- an input system coupled to establish in the active media an initial state corresponding to an input pattern;
- and
- a sensing system coupled to measure the active media at the separated locations to identify which of the final states the active media has after the evolution time, wherein the identification of the final state indicates a feature of the input pattern.
A pattern recognition system comprising:
- a first active media having states that respectively evolve over time to a first set of distinguishable final states;
- an input system coupled to establish in the first active media an initial state corresponding to an input pattern;
- a sensing system coupled to measure the first active media at separated locations to identify which of the first final states the first active media has after an evolution time, wherein the identification of the first final state indicates a first feature of the input pattern;
- and
- a second active media having states that respectively evolve over time to a set of second final states, wherein:
- the input system is coupled to establish in the second active media the initial state corresponding to the input pattern;
- and
- the sensing system is coupled to measure separated locations of the second active media for identification of which of the second final states the second active media has.
