In artificial ventilation of neonates uncuffed endotracheal tubes are commonly used. The unknown leakage hampers the detection of spontaneous breathing. A new method to measure respiration by using antennae has recently been presented. A respective setup is investigated numerically and experimentally. Both approaches show that the method seems capable of allowing a contactless triggering to synchronize ventilation. The results are compared to derive a better understanding of influencing factors.

The possibility to estimate the resulting DVOR bearing error caused by multiple WTs summating the known errors of the particular WTs is investigated. The linear addition is found to be not suitable for use as a worst case estimation. Good estimations are achieved by the geometrical addition in proximal operation distances. In general bearing errors are decreasing with rising distance of WT and analysis point from DVOR. So the estimations can be interpreted as a kind of worst case values.

To investigate the possible interference of wind turbines with terrestrial navigation aids and Radar systems, the signals of these systems have to measured in the air space used by aircrafts or being under surveillance, respectively. From the measurements performed in areas with and without wind turbines the influence of these on the signals of terrestrial navigation and/or Radars can be derived. Drone-based and state-of-the-art electronics were used for the measurements.

The coupling behavior of electromagnetic pulses into the shielded enclosure of vulnerable systems is of great interest in order to estimate and to predict the system's reliability. The usage of an optical field sensor reduces the influence of the measuring setup and thus, enables the analysis of the enclosure's resonance behavior, which delivers revealing information about the dependence of the quality factor on the aperture size of the enclosure.

The validation of GTEM cells, which are an established alternative for an open area testside and are used for electromagnetic emission and susceptibilty tests, is performed in time domain with a specifiedl transient pulse with a double exponential shape. This paper provides a new validation method, wich is applicable for any transient pulse and presents further investigations of a GTEM cell in frequency domain.

In this paper the electromagnetic field distortion of a DVOR surveillance navigation system in presence of a wind turbine (WT) is investigated as a function of wind direction and rotor position. Therefor regularities of the distortion behavior were determined by 2040 simulations. Based on the calculated data a method is developed which allows to approximate the worst case distortion with the results of only two simplified simulations, which significantly reduces simulation effort.

The paper presents a statistical approach to estimate the risk of an electronic system to intentional electromagnetic interference. The keywords Smart Grid, Industry 4.0 and Internet of Thinks leads to complex system with many dependencies between each electronic system. A faultless function of that complex systems is needed, which is achieved only with a cost efficent protection. That only can achieved with a stastical estimation of the risk to find the weakest link in the chain.

Keywords: cross correlation method; transient signal transmission Paper Message: Correlation coefficient can be used to qualify the waveguide with respect to signal distortion.

Ethernet connections can suffer from data corruption due to intentional electromagnetic interference. In this paper a software-based measuring method is presented, which allows a direct assessment of the effects on the link layer without an unwanted influence of software related effects on higher protocol layers. This gives a simple tool for a quantitative analysis of the disturbance of an Ethernet connection based on time domain data.
