Abstract
An apparatus and method having a first unit for creating mechanical movement with a certain frequency ofmovement. A second unit is operatively associated with the first unit for producing a pulsing electrical signal that has a pulse rate substantially proportional to the frequency of movement. A third unit is operatively associated with the second unit for producing a pneumatic signal that is substantially proportional to the pulse rate of the pulsing electrical signal.
