  text: 'Modeling and simulation play a key-role in computer-assisted design of ultrasonic
    sensors. The accuracy of those numerical or analytical models highly depends on
    the material dataset chosen as well as on the digitized simplified geometry. Thus,
    researchers worked on techniques how to measure material datasets of piezoceramics
    or passive materials (i.e. polymers) for use in simulation [Rau08] [Rup09]. Most
    computer models neglect the influence of adhesive bonds between those active and
    passive material components used to form a complete ultrasonic transducer and
    thus imply perfect interface layers. To gain a more accurate model one need to
    go further and consider non-perfect interface layers between assembly parts. Because
    adhesive bonds are neither necessarily isotropic nor homogeneous and their geometric
    dimensions are very small, we need to define effective material datasets dependent
    on the model used in simulation. In this contribution the indicator under study
    is the electric impedance of the active element. We will show the influence of
    different adhesives used to adhere metal electrodes on piezoceramic discs. Therefore,
    we use several different types of adhesives (epoxies, cyanoacrylates and perfluorpolyether
    grease) and different sizes of piezoceramic discs (PIC 255, manufacturer: PI Ceramic
    GmbH) of the same batch (thickness, diameter). The electrodes have been cut from
    one plate made of stainless steel using a laser to avoid uncertainty effects due
    to variations in material-parameters. The probes have been prepared in an air-conditioned
    Lab with constant temperature and humidity. The indicators considered to identify
    the effect of those different adhesive films are extracted from the electric impedance
    of the electromechanical converter.'

  text: 'Es gibt unterschiedliche Methoden, um räumliche Schallwechseldruckverteilungen
    in Flüssigkeiten zu erfassen. Viele dieser Verfahren haben zwei Nachteile. Sie
    sind zum einen invasiv, beeinflussen somit die sich ausbreitende Ultraschallwelle,
    und zum anderen sehr zeitaufwendig. Die Visualisierung von Ultraschallfeldern
    mittels Schlierenmethode ist eine schnelle und einfache Methode, um zweidimensionale
    Schallfelder nichtinvasiv zu analysieren. Ein besonderer Vorteil besteht darin,
    dass man unmittelbar resultierende Veränderungen im Schallfeld zum Beispiel bei
    Frequenzänderung, Sensorausrichtung… beobachten kann. In diesem Beitrag werden
    zwei dieser Verfahren vorgestellt. Die modifizierte Schlierenmethode nach Toepler,
    das im Weiteren als modifizierte Schlierenmethode bezeichnet wird, und die Hintergrund-schlierenmethode,
    das sich bisher hauptsächlich zur Strömungsvisualisierung etabliert hat [1]. Im
    ersten Teil werden beide Messverfahren erläutert, die realisierten Messaufbauten
    sowie Einsatzmöglichkeiten für die Schallfeldcharakterisierung kurz vorgestellt.
    Im zweiten Teil werden beide Verfahren verglichen und die Vor- und Nachteile bezüglich

  text: There has been a lot of progress in finding measurable quantities of high
    in- formation content for the inverse determination of piezoelectric material
    properties. Since some material parameters (mainly \textgreek{e}S 11, e15and cE
    44) do not or only marginally influence the electrical impedance over frequency,
    it is not sufficient to look only at the electri- cal impedance of discoidal piezoceramics
    [1]. Moreover, the parameter sensitivities vary with respect to the diameter--thickness
    ratio of the disc and the design of an ultrasonic transducer's piezoceramic has
    to match other requirements than those of a good material characterization [2,
    3]. That is why it is still desirable to find model based approaches for parameter
    identification that either keep the technical effort low (e.g., only an impedance
    measurement) or increase speed of the inversion procedure. In this contribution
    we answer the question if an additional analytical approximation of cE 44, strictly
    following the ideas of Theocaris [4], in conjunction with a single measured elec-
    trical impedance will be sufficient for an accurate simulation of both, electrical
    impedance and surface normal velocity of a piezoceramic disc. Thereby, the remaining
    parameters are identified by means of the Inverse Method. Furthermore, we use
    the parameter ap- proximation as an initial guess and limiting boundary to speed
    up the inverse algorithm if both, electrical impedance and surface normal velocity
    are taken into account within the optimization procedure.

  text: Bei der Luftultraschall-Abstandsmessung mit einem einzelnen Schallwandler
    ist der Mindestabstand durch die Sendesignaldauer und die Ausschwingzeit des Schallwandlers
    begrenzt. Daher führt die Verwendung von codierten Sendesignalen, wie sie z.B.
    für die Unterscheidung mehrerer Sender genutzt werden können, im Allgemeinen zu
    einer Vergrößerung des Mindestabstandes. Dieser Beitrag zeigt, dass der Mindestabstand
    bei codierten Sendesignalen durch eine geeignete Signalverarbeitung, bei der eine
    Trennung des Sende- und Empfangssignals erfolgt, deutlich verringert werden kann.

  text: Simultaneous transmitting and receiving (STaR) enhances the utilization of
    single transducer ultrasound measurement systems. In distance measurement applications
    the dead zone can be reduced to nearly zero, independent of the transmitted signal.
    So it is possible to transmit codedsignals to identify different sensors without
    increasing the minimum distance. The electrical transducer signal consists of
    the electrical transmitted and received signal. A separation of these two signals
    can be done with a mathematical model of the electrical system. For this purpose
    it is necessary to digitize the electrical transducer signal. Due to the relative
    small amplitude of the received signal compared to the transmitted signal amplitude,
    a high resolution analog to digital converter (ADC) is needed. This leads to high
    requirements for the ADC. The necessary resolution limits the sample rate of the
    ADC. By down mixing the transducer signal using a coherent quadrature demodulation
    (CQD), as used in many high frequency ultrasound applications, the sample rate
    of the ADC can be reduced. In this contribution an airborne ultrasound distance
    measurement system with reduced dead zone is used to analyze the effects of this
    concept to the signal conditioning, system identification and system performance.
    The approach is compared with a system without CQD and an ADC with a lower resolution
    but a higher sample rate. By analyzing the pros and cons of both systems the usability
    of a CQD based system for a STaR application is evaluated. The distance measurement
    system used for the experiments is based on a 40 kHz airborne ultrasonic transducer.
    A gyrator based transmit amplifier delivers a system bandwidth of about 10 kHz.
    In the experiments, coded transmitted signals are used to measure the distance
    to a metal reflector. The main objectives are short distances between 0 mm and
    200 mm. Here a separation of transmitted and received signal is necessary. The
    reflector distance is calculated by a cross correlation between transmitted and
    received signal.

  text: For many applications like level measurement and industry robotics it is of
    advantage if the directional characteristic of an ultrasonic transducer is changeable
    or adaptable for the improvement of spatial resolution. Often this goal is reached
    with the use of ultrasonic transducer arrays, which elements are driven with phase
    shifted excitation signals. One disadvantage of these solutions is the great effort
    for building such an array and the multi-channel sensor electronics. In this contribution
    the directional characteristic of a single air transducer with segmented electrodes
    is analyzed. Therefore a variable script based finite element model is used to
    discover the influence of different electrode configurations on the directional
    characteristic of a single piezoceramic transducer. Especially the influence on
    the angle of beam and the near field length are evaluated. The used variable model
    permits an optimization of the configuration with regards to the mentioned criteria.
    The findings will be used for the development of a level measurement system for

  text: There has been a lot of progress in finding measurable quantities of high
    in- formation content for the inverse determination of piezoelectric material
    properties. Since some material parameters (mainly \textgreek{e}S 11, e15and cE
    44) do not or only marginally influence the electrical impedance over frequency,
    it is not sufficient to look only at the electri- cal impedance of discoidal piezoceramics
    [1]. Moreover, the parameter sensitivities vary with respect to the diameter-thickness
    ratio of the disc and the design of an ultrasonic transducer's piezoceramic has
    to match other requirements than those of a good material characterization [2,
    3]. That is why it is still desirable to find model based approaches for parameter
    identification that either keep the technical effort low (e.g., only an impedance
    measurement) or increase speed of the inversion procedure. In this contribution
    we answer the question if an additional analytical approximation of cE 44, strictly
    following the ideas of Theocaris [4], in conjunction with a single measured elec-
    trical impedance will be sufficient for an accurate simulation of both, electrical
    impedance and surface normal velocity of a piezoceramic disc. Thereby, the remaining
    parameters are identified by means of the Inverse Method. Furthermore, we use
    the parameter ap- proximation as an initial guess and limiting boundary to speed
    up the inverse algorithm if both, electrical impedance and surface normal velocity
    are taken into account within the optimization procedure.

  text: Semi-analytical approaches for the description of dispersion in acoustic waveguides
    are based on root finding in a characteristic function. A mode-tracing algorithm
    helps to find all solutions of this problem by consecutively bracketing single
    roots. In this contribution we present a multistage and adaptive mode-tracing
    algorithm, which uses an adaptive step size for the prediction of consecutive
    solutions as well as an adaptive estimation of the search space around these predictions.
    Furthermore we present a validation stage to ensure the correlation between consecutive
    solutions alias waveguide modes.

  text: In single transducer applications it would be desirable if the received electrical
    signal (echo signal) could be evaluated during transmitting. Thereby it is possible
    to measure very short distances. There are some solutions to realize this, but
    they have one limitation which prevents the usage in many industrial application.
    They need a calibration without an echo. The main problem is that this calibration
    has to be repeated whenever the process parameters like temperature or acoustic
    load change. This contribution presents an approach which uses a model identification
    based on different successive measurements which may include echoes. It is done
    by an impulse response decomposition followed by a principle component analysis.
    Results of measurements with sine burst excitation and a reflector in front of
    the transducer are presented.
