Abstract: A self-exciting vibratory device for producing vibration signals in a housing includes actuator means (12) attached to housing (16), sensor means (14) attached to housing (16) and electronics module (18) connecting actuator means (12) and sensor means (14). Actuator means (12) creates vibration signals within housing (16). Sensor means (14) senses the vibration signals created by actuator means (12). Electronics module (18) amplifies and phase shifts the vibration signals sensed by sensor means (14) and containing resonant modes of vibration of housing (16). Electronics module (18) then supplies these amplified, phase shifted signals to actuator means (12) to enhance the vibration of housing (16) at the dominant mode of vibration of housing (16).

Abstract: A method for operating an electrosurgical system including an ultrasound generator and an ultrasonic instrument, includes the steps: determining an initial resonant frequency of the ultrasonic instrument by the ultrasound generator, energizing the ultrasonic instrument by the ultrasound generator with an operating amplitude and an operating frequency which correspond to the initial resonant frequency, tracking the operating frequency of the ultrasound generator with changes in the resonant frequency of the ultrasonic instrument, and terminating the energizing of the ultrasonic instrument by the ultrasound generator. A method terminates the energizing of the ultrasonic instrument by the ultrasound generator, in a decay phase the operating amplitude of the ultrasound generator is reduced to zero with a predefined or predefinable rate of change. An ultrasound generator is also presented.

Abstract: An acoustic levitation system contains an acoustic transducer array emitting acoustic energy of periodically varying intensity. The acoustic transducer array includes a set of transducer elements arranged on a surface extending in at least two dimensions. The transducer elements are controllable in response to a control signal so as to emit the acoustic energy at a wavelength and a phase delay determined by the control signal. A controller generates the control signal such that an acoustic channel comprising one or more high-pressure region enclosing a continuous pressure minimum region that extends along a defined channel path from a start position to an end position. The continuous pressure minimum region enclosed by the one or more high-pressure region represents a trap volume suitable for carrying, levitating and translating matter in a contactless manner.

Abstract: In a vibration unit, a first electrode of a sensor circuit of a control unit is electrically connected to a first external electrode of a first piezoelectric element, a second electrode of the sensor circuit is electrically connected to a second external electrode of the first piezoelectric element, a first electrode of a drive circuit is electrically connected to a first external electrode of a second piezoelectric element, and a second electrode of the drive circuit is electrically connected to a second external electrode of the second piezoelectric element. Only a relatively small voltage induced by an electromotive force occurring due to the flexure of the first piezoelectric element is applied to the sensor circuit. In addition, only a relatively large drive voltage to be applied to the second piezoelectric element is applied to the drive circuit.
