Abstract: An effective bandwidth in a membrane based ultrasonic transducer is improved by a control element (C). The control element (C) is disposed on a first side (10a) of a first membrane (10) of the transducer to increase or decrease a displacement amplitude of the first membrane (10) towards the first side (10a) and/or the opposite, second side (10b). This induces a displacement asymmetry (Za< >Zb) in a motion of the first membrane (10) during a first vibration (V1) of the first membrane (10) to the first side (10a) compared to the second side (10b). The displacement asymmetry may result in improved bandwidth.

Abstract: An acoustic microscope system is described that includes a container for holding a medium with an object to be measured. Compressional waves are generated by a probe into the medium. The compressional waves travel along an acoustic axis to interact with the object. Shear waves are generated by a shear wave source into the medium. The shear waves travel along a secondary axis which intersects with the acoustic axis at the object with a non-zero angle. The shear waves are configured to cause shear wave oscillations directed transverse to the secondary axis and at least partially directed along the acoustic axis. A measurement of the object is determined based on the compressional waves having interacted with the object as a function of the generation of the shear waves.

Abstract: Techniques are described herein for presenting attribute variations (differing attribute values) of an item at a network page. A request for the network page associated with an item of an electronic catalog can be received. In response to the request, the network page can be presented. The content and/or format of the network page can be predefined by an interface specification associated with the item and/or item category for the item.

Abstract: A method and system for controlling an array of piezoelectric transducers (11, 12, 13). Respective driving signals (Vn) are applied to the transducers. The driving signals (Vn) comprise an alternating component (A) oscillating at one or more driving frequencies to cause corresponding vibrations in the transducers for generating acoustic waves (Wn). One or more of the driving signals (Vn) are offset by a respective bias voltage (Bn). The bias voltage (Bn) is controlled to reduce a difference in resonance frequencies between the transducers. To eliminate any remaining difference, the alternating component (A) to at least a subset of the transducers (11,12) is periodically reset. In this way the phases of the resulting acoustic waves (W1,W2) can be synchronized.
