  text: Impulsbasierte Ultraschallsensorsysteme zur Messung von Füllstand, Durchfluss
    und Konzentration sind heutzutage aufgrund ihrer Robustheit und Wartungsfreundlichkeit
    weit verbreitet. Probleme treten immer dann auf, wenn sich Gasblasen im Medium
    befinden. Diese verändern das empfangene Signal derart, dass eine exakte Messung
    der Schallgeschwindigkeit des flüssigen Mediums nicht mehr möglich ist. Dieser
    Beitrag behandelt eine neue Art der Signalauswertung, die eine zuverlässige Bestimmung
    der Schallgeschwindigkeit auch in diesem Fall gewährleistet. Darüber hinaus können
    auch Rückschlüsse auf den Gasanteil innerhalb des flüssigen Mediums gewonnen werden.

  text: Currently there are pulse based ultrasonic sensor systems used to measure
    flow, liquid level, concentration or in process monitoring. In several processes
    the investigated media are a mixture of liquid and solid ingredients (emulsions,
    suspensions). The use of ultrasonic sensor systems will be very complicated if
    gas bubbles appear at the measurement place caused by chemical reactions, high
    temperature or fast flow that means by typical process conditions. Firstly, the
    appearance of gas bubbles falsifies the measured absorption. Secondly, the measured
    velocity is influenced by gas bubbles. In figure 1 is visible that a volume fraction
    of 0.1 ppm of undissolved air decreases the sound velocity by 1.4 m s-1

  text: In vielen verfahrenstechnischen Prozessen ist die kontinuierliche Regelung
    von Prozessgrößen für einen stabilen und sicheren Betrieb eine wichtige Vorraussetzung.
    Die Erfassung der Zielgrößen geschieht aufgrund von hoher Robustheit und Wartungsfreundlichkeit
    zunehmend mit akustischen Messverfahren. Besonders impulsbasierte Messsysteme
    werden häufig zur Messung von Durchfluss, Füllstand und in der Flüssigkeitsanalytik
    auch zur Konzentrationsmessung benutzt. Dabei führen am Messort auftretende Gasblasen
    zu großen messtechnischen Problemen. Sie verändern die gemessenen akustischen
    Stoffkenngrößen, wodurch es zur fehlerhaften Regelung bestimmter Prozesszielgrößen
    kommt.

  text: Today headlights are built with transparent polycarbonate front windows. If
    the air moisture inside the headlight is high and the outside temperature decreases
    below the dew-point, the air moisture condensates inside and the inner surface
    of the polycarbonate front window (PCFW) becomes nontransparent (figure 1). To
    the costumer this appears as an optical defect.In order to avoid the condensation
    and to speed up the evaporation of the condensed water (condensate) on the PCFW
    a Computational-Fluid-Dynamic-simulation is used. The simulation results are proceeded
    to optimise the airflow and the arrangement of the breather holes. An important
    problem is the validation of the simulated results with the reality. It was necessary
    to build a non-invasive measurement system for the continuous characterisation
    of condensated areas without affecting the material properties, the airflow and
    the light distribution inside the headlight.

  text: In the 1950's many investigations have been made in measuring the Young's
    and the shear modus of isotropic materials with acoustic waves. Therefore both
    the longitudinal and transversal sound velocities have been determined with only
    one specimen, that had to be large in comparison to the wavelength (Brown, Reynolds,
    Dunegan). Therewith the method was suited only for low absorbing materials. In
    the 1990's further developments led to mono mode rods to describe viscoelastic
    properties. Their diameters had to be very small for high frequencies, thus giving
    practical values up to 65 kHz (Benatar). This contribution is about a tubular
    multi mode specimen and its application for the simultaneous measurement of the
    abovementioned acoustic properties at high frequencies.

  text: "In den bekannten grundlegenden Ausf¨uhrungen zur Erzeugung hörbaren Schalls
    durch Eigendemodulation amplitudenmodulierten\r\nLeistungsultraschalls (siehe
    u.a. Westervelt, Berktay) wird von zwei räumlich übereinander\r\nliegenden Wellen
    unterschiedlicher Frequenz im nichtlinearen Medium ausgegangen, so dass neben
    ihren\r\nHarmonischen auch Summen- und Differenzfrequenzen entstehen. Die perfekte
    räumliche Ueberdeckung\r\nder Wellen im Freifeld kann mit herkömmlichen Schallwandlern
    allerdings nur unzul¨anglich erreicht werden.\r\nTrotzdem sind in der Vergangenheit
    einige so genannte parametrische Lautsprecher entwickelt worden. Um\r\nannähernd
    die erwähnten Voraussetzungen zu gewährleisten, sind gängige Systeme mit einem
    Durchmesser\r\nvon ca. 30 cm relativ groß. Dies soll auch dem angestrebten Sekundärschalldruck
    Rechnung tragen, der linear\r\nmit der effektiv abstrahlenden Fl¨ache wächst.
    Zum Aufbau dieser großen Flächen werden teilweise viele\r\nkleine Ultraschallwandler
    zu einem Array zusammengesetzt. Der hohe Preis einzelner Wandler aber auch\r\ndie
    notwendige Sortierung beispielsweise bezüglich ihrer Mittenfrequenz macht den
    Aufbau solcher Systeme\r\naufwändig. Erst am vollständig aufgebauten Array werden
    schließlich Frequenzgang und Richtcharakteristik\r\ndes Sekundärschalls ermittelt.
    Im Sinne kürzerer Entwicklungszeiten und -kosten wäre es wünschenswert,\r\nbereits
    vor dem Aufbau des Arrays allein durch Untersuchung des einzelnen Ultraschallwandlers
    eine Prognose\r\nüber die zu erwartenden Eigenschaften des Gesamtsystems vornehmen
    zu können. In diesem Beitrag\r\nwird ein Versuchsaufbau vorgestellt, der unter
    strenger Beachtung der anfangs erwähnten Voraussetzungen\r\ndie parametrische
    Schallerzeugung mit nur einem Ultraschallwandler kleiner Baugröße erlaubt. Die
    Frequenzg\r\nänge des Sekundärschalls von Einzelelement und Array werden bei entsprechender
    Distanz gegen¨ubergestellt.\r\nVorzüge des neuen Messaufbaus, beispielsweise die
    Möglichkeit zur Variation von Druck, Temperatur\r\noder Luftfeuchtigkeit, um atmosphärische
    Einflüsse auf die parametrische Schallerzeugung zu untersuchen,\r\nwerden skizziert"

    Practically wide arrays of many small ultrasonic transducers are used, but the
    generation of very low frequencies is always weak. This contribution is about
    the experimental investigation of the {\textquotedbl}generation zone{\textquotedbl}
    -- that is the distance between the ultrasonic loudspeaker and the listener --
    and the decrease of the lower frequency bound of the audible sound beam with distance.
    The main focus is on the experimental setup, which permits the parametric sound
    generation with only one ultrasonic transducer and a waveguide. In addition, the
    new measurement setup enables to show an additional effect: The de-coherence of
    the primary ultrasound wave which may be caused by saturation of air. This is
    why the lower frequency bound decreases as well if we approach the ultrasonic
    transducer.'

  text: The classical forms of noise present in the frequency of MEMS resonators have
    been recently investigated and described in detail. The present paper extends
    this investigation to 1/f noise. That is of fundamental nature in microelectromechanical
    systems (MEMS) resonators, and is given by the universal quantum 1/f effect. In
    recent years new piezoelectric and compound semiconductor materials have been
    developed along with advanced manufacturing technologies for MEMS including them.
    These technologies enable the deposition of thin compound semiconductor, or PZT
    films and their integration into MEMS devices.

  text: The appliance of time-reversal acoustics to classical trans-ducer design,
    medical, technical or audible range applica-tions brings forward new ideas whenever
    we need both, focusing acoustical energy in time and space. Unfortunately, the
    spatiotemporal focusing is limited through the amount of applied transducer elements
    as well as the ergodicity and randomness of the cavity [1]. This paper will show
    how the simulated annealing technique, a multi-objec¬tive optimiza-tion algorithm
    [2], is used to increase the nar¬rowness of the refocused spot by breaking up
    randomness for the benefit of ergodicity in a predetermined cavity.

  text: Currently there are ultrasonic sensors to measure flow, liquid level, concentrations
    or to monitor the process course. In several processes the investigated media
    is a mixture of liquid and solid ingredients. The use of ultrasonic sensor systems
    will become very complicated if gas bubbles appear at the measurement place caused
    by chemical reactions, high temperature or fast flow this means under typical
    process conditions. The appearance of gas bubbles falsifies the measured absorption
    and also the velocity. The sound propagation in liquid mixtures is influenced
    in a complex manner for instance by solid particles, rapid changes of temperature,
    and liquid droplets of other density in the measured liquid simultaneously. For
    the detailed investigation of the influence of bubbles on sound propagation, an
    experimental setup was build. This setup permits the comprehensive processing
    of transmitted and scattered signals. Using a smart signal processing it is possible
    to find a reliable indication for gas bubbles.

  text: Today there are many different ultrasonic sensors to measure flow, liquid
    level and concentrations or viscosity in several processes. One of the biggest
    problems by doing the measurement using ultrasonic sensors is the appearance of
    bubbles at the measurement place caused by chemical reactions, high temperature
    or fast flow. These bubbles falsify the received signal and the measurement becomes
    erroneous. Therefore, it is useful to know if there are gas bubbles or not. It
    is important to obtain the information about bubbles in real-time, how ever the
    detection of the signal amplitude is not reliable to detect gas bubbles. The amplitude
    is influenced by solid particles, rapid changes of temperature and liquid droplets
    of other densities in the measured liquid. These arguments are the motivation
    to find new possibilities to detect the appearance of gas bubbles in liquids independent
    of the transparency and rheological properties of liquid.

  text: Die elektrische Impedanzmessung ist heute in einem weiten Frequenzbereich
    technisch möglich und wird vielfach zur Materialcharakterisierung eingesetzt.
    Neben den elektrischen und optischen Messverfahren verfügen aber auch gerade die
    akustischen Messverfahren über vorteilhafte Applikationseigenschaften wie Robustheit
    und geringe Wartungsanforderungen. Die zuverlässige Bestimmung der Schallkennimpedanz
    als eine der drei akustischen Stoffkenngrößen erweist sich aber noch heute als
    sehr diffizil, wie im Folgenden gezeigt wird.

  text: One of the most widely spread measuring tasks in chemistry or food technology
    is the continuous determination of fill levels in liquid tanks. The aim of this
    paper is to present a new contactless and noninvasive measuring method based on
    ultrasonic time-reversal and correlation techniques. The novel method enables
    asserted fill levels to be identified and small deviations of them to be calculated
    even if the direct path from the sensor to the liquid surface is obstructed. This
    article will present the structure and principle of the measuring system as well
    as the procedure of signal processing. A simulative approach is used to demonstrate
    the excitation of a virtual sound source in the liquid and to show both the advantages
    and limits of the new technique. In addition a simplified model is developed where
    the solutions of the simulations are applied to.

  text: The determination of small liquid volumes and their changes over a period
    of time is a measuring problem with increasing importance considering the growing
    market of micro-systems. In this paper, experimental investigations are described
    which aim to observe the growth of droplets at the end of a micro channel, such
    as a cannula or capillary. The main focus of the work lies on the calculation
    of flow rates below 1 millilitre per hour. Furthermore, the potential of the measuring
    equipment for liquid level and surface tension measurement is described.
