摘要: 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.

摘要: Various embodiments of the present invention are directed to external, electronically controllable modulators. In one embodiment, a modulating device (100,400) includes a first electrode (104,404), a second electrode (106,406), and an active region (102,402). The active region is configured so that at least a portion of the active region is disposed between the first electrode and the second electrode. Applying a voltage of an appropriate magnitude and polarity to the electrodes changes the conductivity of the active region which in turn shifts the phase and/or amplitude of electromagnetic radiation transmitted through the active region.
