Greatings, I am working on design and fabrication of a CMOS motion detector IC that I have classified as being fuzzy. The fol- lowing is a description of the circuit. It has 10 digital inputs and a final output. A strong voltage on the output (near VDD) means that majority of the inputs were fired in the preferred direction, otherwise output is silent. There is no feedbacks and therefor no neural-net like back props in this circuit. It detects motion in real time. Circuit is biologically motivated and operates in subthreshold. Here is a question. Basically what is the application of this circuit in real life ? . I have thought of waveform detection in scopes myself, but need more ideas. I appreci- ate all comments.

Over the last few years a number of people have been looking at what have been called Smart Geophones. As I understand your IC the 10 inputs would be looking at the same component of particle displacement. You might want to have them look at a variety of components?
