  text: 'One method to generate focused sound is to transmit amplitude modulated ultrasound
    of high energy in a nonlinear medium, so that sum and difference frequencies develop.
    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: "In der industriellen Messtechnik werden optische, chemische und akustische
    Messverfahren zur Ermittlung von Prozessgrößen eingesetzt. Dabei haben die akustischen
    Messverfahren aufgrund ihrer Robustheit und Wartungsfreundlichkeit ein sehr großes

  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.

  text: In diesem Beitrag werden Messungen und Auswertungen der Ultraschallgeschwindigkeitsmessung
    zur Überwachung von Hefekultivierungen vorgestellt. Die Ultraschallgeschwindigkeit
    ist abhängig von Biomasse-, Glukose- und Ethanolkonzentration, aber auch von anderen
    Bioprozessvariablen. Um den Einfluss von Blasen auf das Signal zu reduzieren,
    wurde der Ultraschallsensor in einem Bypass-System eingesetzt. Es wurden Messungen
    sowohl im Flow- als auch Stop-Flow-Betrieb durchgeführt. Um die richtigen Informationen
    aus diesem unspezifischen Signal zu erhalten, wurde ein multilineares Regressionsmodell
    berechnet, wobei die Biomasse-, Glukose- und Ethanolkonzentration als unabhängige
    Variablen dienten. Ein Beispiel der Ergebnisse ist in Abbildung eins gezeigt.
    Es sind die Biomasse-, Glukose- und Ethanolkonzentration während einer Saccharomyces
    cerevisiae Kultivierung dargestellt. Die Parameter des multilinearen Regressionsmodells
    wurden durch Verwendung der Daten aus der dargestellten Kultivierung identifiziert.
    Wird dieses Modell zur Auswertung auf die Signale anderer Prozesse übertragen,
    ist das Ergebnis ähnlich, jedoch vergrößert sich der Fehler der Schätzung. Die
    Ergebnisse sowie Erfahrungen werden ausführlich in dem Beitrag diskutiert.

  text: Nowadays the use of ultrasonic sensors for process control for flow, level
    or concentration measurement is wide spread. In this application there are high
    demands for a defined and stable quality of the properties of such ultrasonic
    sensors. For the detailed investigation and characterization of ultrasonic sensor
    properties an efficient PC-controlled measuring system has been developed at ifak.
    In this report this new high performance approach will be presented to make the
    vibrating ultrasonic sensor surface and also the sound field in front of acoustic
    sensors in liquids visible.

  text: Recently there has been increased demand for chemicaJ sensors measuring in-line
    the concentration of selected substances in complex liquids in order to guarantee
    a high product quality in the process industry. At present there is a great interest
    in acoustic sensor systems for concentration measurements. This article presents
    a new ultrasonic sensor system consisting of a miniaturized multi-sensor arrangement
    for the comprehensive acoustic characterization of liquid mixtures. The sensor
    system measures sound velocity, impedance coefficient, attenuation coefficient
    an9 temperature.
