Shortcomings of single cuff blood pressure devices have led to research of devices with more than one cuff for improved accuracy. We assessed two devices that use two cuffs and one device that uses three cuffs. The devices with two cuffs use one occluding arm cuff an...

Technology for modifying the local temperature of a material is tested for hot forming. A system for selective controlled cooling was designed for this purpose and a workplace enabling heating, local cooling and material forming was built. This paper describes the principles and po...

Small satellites such as CubeSats are not adequately protected in the cosmic environment from ionizing radiation due to the low weight limit, which does not allow the use of heavy shielding materials with the high atomic number. Therefore, the power supply system of such small...

The Wingate Anaerobic test (WAT) is the most popular test for estimation a person's anaerobic capacity. Because anaerobic performance is important for many athletes, the most well-known application of the Wingate test is in sports medicine. But there is also more. The Wingate t...

The following topics are dealt with: artificial satellites; CMOS integrated circuits; switching convertors; reliability; DC-DC power convertors; failure analysis; oscillators; capacitors; solar power satellites; network topology.

This paper presents a design concept of new radio communication subsystem, intended for use on the PilsenCUBE nanosatellite. The hardware and software solution is based on previous experiences with the VZLUSAT-1 setup and operation. Our aim is to overcome weak points which were fou...

This article presents the recent (2017-2018) electronics modifications for the upgrade o the TOTEM roman pot detectors at the CERN LHC. To improve the timing accuracy and reliability the new Roman Pot detector configuration utilizes both DSDD (Double Side Diamond Detector) an silicon&#x...

One of the main goals of the PilsenCUBE-II picosatellite project is to offer on board payload space for the student's experiments for the students from the various secondary schools of the western Bohemia. The students experiments have to be simple enough in scope of skill...

This paper is focused on input impedance optimization of a stripline. The stripline for electromagnetic susceptibility testing represents a radiating structure which is composed of one active and one or more grounded conductors. The characteristic impedance of the stripline is given by ...

This paper is focused on optimization of electrical properties of 50 ohm stripline which was described in international standard for the automotive industry ISO 11452-5. The standard shows the dimension of the stripline but information about impedance matching is missing - and this ...

This article describes experimental measurements of a skin temperature in vicinity of a surgical wound. Measurements were carried out in collaboration with the orthopedic department of the University Hospital Olomouc, Czech Republic. A system used for sensing, transmission and visualization of&#x...

Human movement analysis is a research field with clinical and biometrics application. It has been shown useful in the objective measurement of gait, balance, falls risk assessment and mobility monitoring. Running and/or walking are also integral activities to most athletic disciplines. ...

This paper deals with dissipativity, stability, chaotic behavior and related structural properties of a relatively broad class of finite dimensional strictly causal systems. The class of nonlinear systems under consideration is described in the state-space representation form. System properties are&#x...

In the present paper a preliminary design and implementation of a readout interface for strip detectors, using Applied Specific Integrated Circuits (ASICs) is discussed. Key issues are the parameters and features of the main constituent parts of the system: strip detectors, ASICs and&#x...

The paper focuses on a selection process of boost diodes for Active Power Factor Correctors (APFC) based on the Boost converter. The choice of the suitable boost diode plays crucial role for an efficiency of APFC. The main aim of the paper is devoted to theoretical a...

This paper deals with the problem of the short distance measurement between two (or more) moving points with the ability of a simple data communication. Different possibilities were explored and using the ultrasonic transceiver was then chosen for a future development. The article ...

The paper presents a design of a four way signal splitter working in L frequency band, for standard GNSS (Global Navigation Satellite Systems) signals. These splitters are used when more than one receiver has to be connected to one signal source, like an antenna, a signal...

Single cuff automatic blood pressure (BP) measurements are subject to errors because the BP values are based on statistical estimation rather than on physiological principles. We developed a dual cuff experimental system that uses an arm cuff and a wrist cuff. The wrist cuff f...

Reliability of electronics is in the automotive industry very important. The average age of cars in Germany was 9 years at 2015.i Normally the life time is evaluated by the environmental test according ISO 16750. The content of this paper is to contribute that computer si...

This work deals with 4 th Generation Long Term Evolution (LTE) standard for mobile telecommunication. LTE comes with new approaches how to increase speed and stability of wireless data transmission. Planning these networks involves many complex tasks, therefore advanced software tools are&#x...
