The so-called Sens-o-Spheres measure the temperature and in future the oxygen content and the pH of fluids. In order to evaluate the distribution of the measured values within the process, it is necessary to locate the wireless sensors. Because of the small size of the sphere (diameter 8 mm), inhomogeneous ambient media and the size of the reactor (less than 2 m), an inductive locating by magnetic fields with a frequency of f = 13.56 MHz is necessary. Since the behaviour of the magnetic field is very different from that of the electromagnetic wave, new locating methods are required, which are presented in this paper.","lang":"eng"}],"department":[{"_id":"59"},{"_id":"485"}],"user_id":"38240","_id":"21524","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"language":[{"iso":"eng"}],"keyword":["oxygen content","inhomogeneous ambient media","magnetic field","inductive locating method","miniaturized wireless sensors","inhomogeneous dielectrics","conventional rod probes","Sens-o-Spheres measure","frequency 13.56 MHz"],"related_material":{"record":[{"status":"public","id":"21524","relation":"earlier_version"}]},"publication_identifier":{"isbn":["9781728110318"]},"publication_status":"published","citation":{"ama":"Lange S, Schröder D, Hedayat C, Otto T, Hilleringmann U.

Therefore, acoustic microphone geometry calibration has recently become a very active field of research. This article provides an application-oriented, comprehensive survey of existing methods for microphone position self-calibration, which will be categorized by the measurements they use and the scenarios they can calibrate.

Furthermore, changing conditions like temperature and pressure result in varying acoustic properties of the liquid. That might necessitate an adaption of the ultrasound irradiation. To detect such changes during operation, process monitoring is desired. Labor intensive processes, that might be carried out for several hours, also require process monitoring to increase their reliability by detection of changes or malfunctions during operation. In some applications cavitation detection and monitoring can be achieved by the application of sensors in the sound field. Though the application of sensors is possible, this necessitates modifications on the system and the sensor might disturb the sound field. In other applications harsh, process conditions prohibit the application of sensors in the sound field. Therefore alternative techniques for cavitation detection and monitoring are desired. The applicability of an external microphone and a self-sensing ultrasound transducer for cavitation detection were experimentally investigated. Both methods were found to be suitable and easily applicable."}],"status":"public","publication":"Ultrasonics Symposium (IUS), 2012 IEEE International","type":"conference","keyword":["cavitation","chemical reactors","microphones","process monitoring","reliability","ultrasonic applications","ultrasonic waves","acoustic properties","cavitation based ultrasound applications","cavitation intensity","change detection reliability","external microphone","malfunction detection reliability","nonperturbing cavitation detection","nonperturbing cavitation monitoring","process monitoring","self-sensing ultrasound transducer","sonochemical reactors","sonochemistry","ultrasound cleaning","ultrasound irradiation","Acoustics","Liquids","Monitoring","Sensors","Sonar equipment","Transducers","Ultrasonic imaging"],"language":[{"iso":"eng"}],"_id":"9783","department":[{"_id":"151"}],"user_id":"55222","year":"2012","page":"1141-1144","citation":{"ama":"Bornmann P, Hemsel T, Sextro W, Maeda T, Morita T.

Notably during times when the GPS signal has a poor quality, e.g. due to the lack of a sufficiently large number of visible satellites, the INS, which may consist of a gyroscope and an odometer, will lead to improved positioning accuracy. In this paper we show how velocity information obtained from GSM (global system for mobile communications) signalling, rather than from a tachometer, can be used together with a gyroscope sensor to support localization in the presence of temporarily unavailable GPS data.
