Thanks. I'll consider that.

Not very. Indeed, the important part is the asymmetric acceleration - higher in one direction with a slower return. I want a miniature device - think pager-motors. Jack hammers are a tad too big.

Yes. That was my thinking too. I mentioned DCT ([Discrete] Cosine transform) which has good signal de-correlation attributes. I'm glad this idea was not so far-fetched. Would FFT be better than DCT (or DST = Sine Transform)? What exactly are "sinusoidal harmonic vibrators"?

The mechanism is as drawn in the diagram. It is not the Whitworth shaper, but it was designed to has an asymmetric acceleration profile.

Say I have a mechanical device like this one: If I plot the acceleration profile at (trace-) point D I get something that looks something like this: Now, here's the question: Can I build a device composed of one of more (eccentric rotating mass) vibration motors that when rotating...
