In this work the feasibility study of a medical equipment based on electromagnetic technology for breathing detection is presented; this system was designed to detect a victim buried from a landslide through the sensing of the thorax displacements due to breathing activity. The system was preliminary tested into a controlled environment and subsequently in a real scenario (a road construction site)...
In this work, the development and the testing of a capacitive distance sensor, based on E-field measurement, for applications in industrial environments is presented. In particular, the structure and the working principle of the sensor, as well as the process of optimization of the sensing elements and some functional tests in absence of disturbances are described. Then, the EMC precompliance, in...
The paper describes a set of measurements carried out in a reverberating chamber and aimed to characterize the field statistics when the source stirring technique is applied. Twenty antennas are used to build up the radiating system and to cover the operational frequency range 1 GHz–3 GHz. The quartiles of the received power distributions are analyzed over a wide frequency range showing satisfactory...
The paper describes an analytical model applied to study the behavior of an antenna moving inside a resonant cavity. It is the basic step to develop a source stirring mode reverberation chamber (RC). The model is able to account for the different coupling of the source with the many cavity modes. The results obtained for a simple dipole are used to design an array of 50 dipoles, whose generated electromagnetic...
