Time difference of arrival (TDOA) based indoor ultrasound localization systems are prone to multiple disruptions and demand reliable, and resilient position accuracy during operation. In this challenging context, a missing link to evaluate the perfor

We discuss two methods to detect the presence and location of a person in an acoustically small-scale room and compare the performances for a simulated person in distances between 1 and 2 m. The first method is Direct Intersection, which determines a

We propose an asynchronous acoustic chirp slope keying to map short bit sequences on single or multiple bands without preamble or error correction coding on the physical layer. We introduce a symbol detection scheme in the demodulator that uses the s

In this article, we propose a new robust, stable, accurate, and efficient time-delay estimation scheme for the angle-of-arrival (AoA) ultrasonic indoor single-source localization systems. The AoA technique employing microphone arrays and ultrasonic s

We present a novel approach for locating a smartphone in mixed non-line-of-sight (NLOS) and line-of-sight (LOS) environments when the positions of the sensor nodes are unknown. The reception times of acoustic signals emitted by the smartphone are use

The resilience of indoor localization systems is a main concern of their industrial application. A combination of different techniques can enhance the overall robustness of such systems. In this work, we present fusion possibilities of coarse Bluetoo

In this paper, we propose a system that is capable of detecting the breath rate of an athlete. Furthermore, we investigate equivalences with the tidal volume over the inclination angle of the thorax to analyze correlations with the respiratory minute
