Abstract: In a method and apparatus for the mechanical strength testing of components with respect to a strength criterion an acoustic pulse in the form of an acoustic shockwave is introduced into a component to be tested such that the shockwave is reflected acoustically with a polarity reversal at a reflection location before passing though a region of the component to be tested, thereby subjecting that region to tensile stress. The amplitude of the shockwave is selected such that the component is destroyed if it does not meet the strength criterion.

Abstract: An ultrasound imaging apparatus employs an ultrasound sensor arrangement formed by an at least two-dimensional sensor matrix and an imaging lens to generate signals which are used to calculate a true-to-scale, real-time, three-dimensional image of a subject according to the pulse-echo principle. A therapy apparatus using such an ultrasound imaging apparatus as its locating system is also disclosed.

Abstract: A pressure pulse source for generating acoustic pressure pulses in an acoustic propagation medium has a foil arrangement formed by a number of electrically contacted piezoelectric foils stacked directly on top of one another with no interstices between the foils, and employs a drive system for driving the individual foils in succession according to the traveling wave principle.
