    Abstract: A method for producing an ultrasonic transducer including an arrangement determination step of determining an arrangement of piezoelectric elements in a stack on the basis of mechanical quality factors of the respective piezoelectric elements; and an assembly step of assembling the stack in which the piezoelectric elements are arranged according to the arrangement determined in the arrangement determination step, a horn, and a back mass. In the arrangement determination step, the arrangement of the piezoelectric elements is determined so that the difference in mechanical quality factor between the piezoelectric elements adjacent in the longitudinal direction is within 5% of a mean value of the mechanical quality factors of the piezoelectric elements.

    Abstract: Delay line memory device, systems and methods are disclosed. In one aspect, a delay line memory device includes a substrate; an electronic unit disposed on the substrate and operable to receive, amplify, and/or synchronize data signals into a bit stream to be transmitted as acoustic pulses carrying data stored in the delay line memory device; a first and a second piezoelectric transducer disposed on the substrate and in communication with the electronic unit, in which the first piezoelectric transducer is operable to transmit the data signals to the acoustic pulses that carry the data through the bulk of the substrate, and the second piezoelectric transducer is operable to transduce the received acoustic pulses to intermediate electrical signals containing the data, which are transferred to the electronic unit via an electrical interconnect to cause refresh of the data in the delay line memory device.

    Abstract: Transducer driving methods and transducer driving systems are described. According to one aspect, a transducer driving method includes providing a plurality of initial driving signals to a transducer, wherein each of the initial driving signals has a respective one of a plurality of different frequencies, identifying one of the frequencies where the transducer has a reduced impedance as a result of the provision of one of the initial driving signals having the one frequency to the transducer compared with impedances of the transducer resulting from the provision of others of the initial driving signals having others of the frequencies to the transducer, determining that the identified one of the frequencies is not acceptable for driving the transducer, as a result of the determining, identifying another of the frequencies, and driving the transducer using another driving signal having the another frequency.
