text: For the measurement of process data in bioreactors, very small wireless sensors
are currently under development to replace the conventional rod probes. 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.

text: Today, we are often surrounded by devices with one or more microphones, such
as smartphones, laptops, and wireless microphones. If they are part of an acoustic
sensor network, their distribution in the environment can be beneficially exploited
for various speech processing tasks. However, applications like speaker localization,
speaker tracking, and speech enhancement by beamforming avail themselves of the
geometrical configuration of the sensors. 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. Selected methods will be evaluated
comparatively with real-world recordings.

text: In this paper we present a system for indoor navigation based on received
signal strength index information of Wireless-LAN access points and relative position
estimates. The relative position information is gathered from inertial smartphone
sensors using a step detection and an orientation estimate. Our map data is hosted
on a server employing a map renderer and a SQL database. The database includes
a complete multilevel office building, within which the user can navigate. During
navigation, the client retrieves the position estimate from the server, together
with the corresponding map tiles to visualize the user's position on the smartphone
display.

text: To optimize the ultrasound irradiation for cavitation based ultrasound applications
like sonochemistry or ultrasound cleaning, the correlation between cavitation
intensity and the resulting effect on the process is of interest. 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.

text: 'A hydrothermal method utilizes a crystallization process in the solution
so that the pure and high-quality powders can be realized. Sintering from the
hydrothermal KNbO3 and NaNbO3 powders, a high-dense lead-free piezoelectric (K,Na)NbO3
ceramics could be obtained (density: 98.8\%). Concerning about the g33 constant,
high value as large as commercial PZT ceramics was measured. Therefore, the hydrothermal
(K,Na)NbO3 ceramics is usable for the sensors and the energy harvesting devices.
To demonstrate the (K,Na)NbO3 ceramics, a hydrophone sensor was fabricated and
evaluated.'

text: A combination of GPS (global positioning system) and INS (inertial navigation
system) is known to provide high precision and highly robust vehicle localization.
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. We propose a sensor fusion system architecture and present
simulation results that show the effectiveness of this approach.

text: 'In neurosurgery, delineation of tumor boundaries during resection of brain
tumors is of substantial relevance. During operation distinction between tumor
and healthy tissue rely on the abilities of the surgeon based on visual and tactile
differentiation. In this paper a high sensitivity actuator-sensor system using
a piezoelectric bimorph is presented. Frequency shift and transfer function of
the bimorphpsilas voltages are detected and evaluated. Sensorpsilas sensitivity
is evaluated using two frequency controls strategies: A phase-locked loop (PLL)
and a self-oscillating circuit. Results of measurements conducted on gel-phantoms
are presented and discussed.'
