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
ausgewählter Messaufgaben bewertet. '

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
bulk solids.
