Abstract
A transducer responsive to a mechanical input produces a binary coded electrical signal on a single data bus. A plurality of piezoelectric elements each produce a voltage pulse when stressed and an actuator applies stress to the elements to generate a sequence of voltage pulses. The elements are coupled to the data bus according to polarity to establish a coded sequence of polarized pulses.
