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.
Regards,

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?
