    Abstract: The present invention relates to a device for the ultrasonic processing of materials, which has an ultrasonic processing system, which comprises: an ultrasound generator, a converter (12), a sonotrode (16), and a counter tool (18); wherein the sonotrode (16) and/or the counter tool (18) has a substantially cylindrical sealing surface having at least one elevation (45) and can be rotated such that, during the processing, the elevation (45) rotates about the axis of rotation and comes in contact with the material web (20) during a sealing time, wherein a control apparatus (24) is provided for the ultrasound generator, to which control apparatus a feedback variable from the ultrasound processing system is fed and which control apparatus determines a manipulated variable therefrom and feeds said manipulated variable to the ultrasound generator, wherein a process variable from the processing process is determined and is linked to the manipulated variable determined by the control apparatus (24) before the feeding to the ultrasound generator. In order to provide an improved device for the ultrasonic processing of materials having an ultrasonic processing system, a trigger apparatus (44) is provided, which determines the position of the elevation (45) and is designed to permit or prevent the linking of the process variable to the manipulated variable in accordance with the position determination.

    Abstract: Methods and devices are described for driving ferroelectric perovskite oxide crystals to achieve polarization inversion with reduced coercivity. In some embodiments, the anisotropy in the potential energy surface of a ferroelectric material is employed to drive polarization inversion and switching with a reduced coercive field relative to uniaxial excitation. In some embodiments, polarization inversion with reduced coercivity is produced via the application of an electric field that exhibits a time-dependent orientation, in contrast with conventional uniaxial electrical excitation, thereby causing the central ion (and the crystal structure as a whole) to evolve along a lower-energy path, in which the central ion is driven such that it avoids the potential energy maximum. This may be achieved, for example, by applying at least two non-parallel time-dependent voltages (e.g. bias, potential) such that orientation of the electric field changes with time during the switching cycle.

    Abstract: An electrical waveform generator for driving an electromechanical load includes a digital signal processor connected to a waveform generator component in turn connected to an amplifier section with a filter network, the latter being connected to sensing and conditioning circuit componentry that is in turn connected to analog-to-digital converter circuitry. A digital memory stores digitized voltage and current waveform information. The processor determines a phase difference between voltage and current waveforms, compares the determined phase difference to a phase difference command and generates a phase error or correction signal. The processor also generates an amplitude error signal for inducing the amplifier section to change its output amplitude to result in a predetermined amplitude error level for a respective one of the voltage and current waveforms.
