Ball and disk integrators are beautiful and the SMithsonian has a gorgeous Henrici Harmonic ANalyzer (19th centruy FFT box) on display with several of them working in parallel. But you probably have a B&D integrator on your desktop right now. The second most valuable "mouse" to come out of California. Open it up; you'll see two disks bearing on the ball, driving opto-encoders most likely. Same good old principle. [BTW, California's 1st most valuable mouse was created by Walt D.]. -- Mike Knudsen Bell Labs(AT&T) att!ihlpl!knudsen knudsen@ihlpl.att.com Round and round the while() loop goes; "Whether it stops," Turing says, "no one knows!" Shotguns -- just say PULL!
