—In this paper the simple and robust method of measuring the pulse rate is presented. Elaborated algorithm allows for efficient pulse rate registration directly from face image captured from webcam. The desired signal was obtained by proper channel selection and principal component analysis. A developed non-contact method of heart rate monitoring is shown(More)
In Gram-negative bacterial cells, disulfide bond formation occurs in the oxidative environment of the periplasm and is catalysed by Dsb (disulfide bond) proteins found in the periplasm and in the inner membrane. In this report the identification of a new subfamily of disulfide oxidoreductases encoded by a gene denoted dsbI, and functional characterization(More)
An electrode matrix and electronic circuit for simultaneous monitoring heart performance and respiration activity is described in the paper. The heart performance is evaluated basing on a mechanical and electrical activity. The mechanical activity is measured using bioimpedance method while the electrical one using a typical approach, i.e. one channel(More)

Recently, an attempt to monitor elders, disabled and/or convalescent people at home has been an emerging discipline of technology and science. Especially, providing a home care based on remote sensing for single and elder persons is a challenging task. An integrated sensor for cardiac, breathing and kinetics of movement activities is developed. It enables a(More)
Gaining information on mechanical contraction of a particular heart chamber is essential in many clinical situations. There are a few techniques which may provide such information, e.g. Magnetic Resonance Imaging (MRI), Multislice Computed Tomography (MSCT) or Ultrasonography (USG). However, each of the mentioned technique has limitations. The main aim of(More)
