http://www.freepatentsonline.com/8024279.html

This patent from Nokia teaches a way to implement a system of pattern recognition and classification using nanoscale resonating elements. Claim 1 reads:

1. Apparatus comprising:

at least one resonator comprising a plurality of nanoscale resonator elements, the at least one resonator having at least two, different resonant frequencies and being configured to provide at least two signals in response to an input signal; and

at least one adder configured to weight the signals with respective weights and to add weighted signals so as to produce an output signal.
