A prototype of an experimental set-up has been built to identify human implemented motor-cognitive control function in a loop control task. Man-machine systems or systems where the human operator is embedded into the control loop (human-in-the-loop) are known and studied since the beginning of the cybernetics in the 60’s of last century. Modern tec...

Aerosol therapy nebulizer is a modern and efficient method of treating respiratory diseases. Nebulization treatment is in a process of development as new drugs intended for this method of care are requiring new ways of aerial administration. A mechanical ventilator (invasive or non-invasive) is often used for these patients and the combination with...

A quite inexpensive instrument for cervical auscultation is described. Provided you already have a laptop computer, an optional MP3 recorder/player and a copy of your preferred sound analyzing software (e.g. PRAAT), then you just need a common microphone (like one of those ready to be connected to the computer) in a proper encapsulation (described)...

The importance for an athlete to control emotion has been widely accepted. However its measurement is still a difficult task. World Archery, an international federation, along with Tabrasco Ltd, wanted to measure the heart rate of their athletes, to help TV viewers understand the inner state of an athlete during main competitions. We present here t...

A planar-spiral antenna to be used in an ultrawideband (UWB) radar system for heart activity monitoring is presented. The antenna, named “twin,” is constituted by two spiral dipoles in a compact structure. The reflection coefficient at the feed point of the dipoles is lower than −8 dB over the 3–12 GHz band, while the two-dipoles coupling is about...

In the last 20 years, a lot of research activity has been carried out on UWB radar in medicine. Over the years, many implementations of medical UWB radars have been presented in literature.
