Abstract
Electronic means, including an analog-to-digital converter responsive to samples of the output from an analog angle sensor directly coupled to an immersed oscillated transducer, is used to trigger the energization of the transducer at each of a predetermined number of equal increments in angle position during each cycle of oscillation of the transducer, with the triggered angle positions during a certain half-cycle of oscillation being interlaced with the triggered angle position during the other half-cycle of oscillation.
