Being able to rapidly detect a low air flow rate with high accuracy is essential for various
applications in the automotive and biomedical industries. We have developed a thermal …

In order to gain the desired information from a sensor and to improve its reliability and
selectivity, efforts in different domains can be taken, eg determining time dependencies or …

Two examples of self-controlled wind and weather sensors for everyday usage based on
temperature-dependent resistors are described and the potential for further enhancing …

A self-validating algorithm is proposed for hot thermistor constant differential temperature air
flow sensor. Through this algorithm, the health of the sensor can be evaluated online, and a …

Im Beitrag werden einfache Witterungssensoren, z. B. an automatisch geöffneten Fenstern,
auf der Basis von Kaltleitern und einfachen Pt-100-Widerstandsthermometern vorgestellt …

In case of large temperature dependencies of the properties, due to sufficient high voltages
and currents the power dissipation in electric devices causes' virtual'electrical impedances …

Abstract The Continues Positive Airway Pressure (CPAP) therapy is the most popular
noninvasive therapy used to treat Obstructive Sleep Apnoea symptoms (OSA). Recent sleep …

A smart, low-cost wind sensor consisting of just two self-heated PTC (positive temperature
coefficient) elements is described. Placing the elements asymmetrically in a cylindrical shell …

Self-validation of sensors is often based on model parameters estimation by calibration. In
order to “repair” the sensor's behavior by correction of the model parameters, it is important …
