Todd's Fascination with Flight

Todd's Fascination with Flight

Now he always knows how high he is in the sky, thanks to a portable altimeter he designed using a micromachined pressure transducer. By exploiting the inverse relationship between air pressure and altitude and compensating for nonlinearities, the device produces acceptable accuracy ( plus or minus 3%) for skydivers in freefall. And after all, Todd lived to tell about it.
