Microcontroller driven battery charger
Michalčík, Bohumil ; Florián, Tomáš (referee) ; Burian, František (advisor)
The first part of the work was dealing in general with switched power supply and types of battery chargers. The second part is made by my own design of microprocessor driven battery charger. The design is based on datasheets and recommended circuit connection. The electrical scheme and also the printed circuit board was designed in Eagle 5.11.0 design system. The battery charger is capable of charging these types of batteries: lead acid, NiMH, NiCd, LiPol a alkaline accumulators, and the maximal output current from charger is 3A. The software implementation and design are also part of this master‘s thesis.

Design of Flow, Temperature and Pressure Measuring System
Macíček, Ondřej ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
This master’s thesis contains complete design of the complex measuring system for temperature, pressure and flow. Objects of measuring are pressure in rabbit’s heart ventricle, flow of the saline through the heart and the temperatures of physiological solution. Work is interested in programming of microcontroller and program for LabVIEW environment, which is used to view and export relevant data related to measuring. Text also contains technical documentation of functional sample of measuring system.

Adaptive frequency filter
Kříž, Petr ; Hájek, Karel (referee) ; Sedláček, Jiří (advisor)
The aim of this work is to design a filter of the type low–pass of order 5th with Butterworth’s approximation in the range of over-tuning 10 – 100 kHz and if it will be possible so! achieve even higher marginal frequencies. To compare two typical representatives of the frequency filters cascading and non-cascading synthesis from the viewpoint the accuracy of an! approximation function, sensitivity to the tolerance values of components, number of the components (mainly OZ) and viability, especially the possibility of electronic over-tuning in selected frequency range. On the basis of these conditions will be chosen one design, which will be realized later. Further it will be necessary to consider the possibilities of electronic over-tuning and to choose for this over-tuning suitable component, to design user management changes of marginal frequency fm by the help of keyboard + LCD and control application on the PC. For this hardware will be programmed appropriate control software. At the end of this work will be constructed appropriate device, which fullfils requirements written above and will be subjected to the laboratory measurements that verify function of this device. The constructional details of the filter are presented in the enclosure at the end of this work. At the CD are available all materials, which were created during the master’s thesis or which are necessarily concerned.

Synchronization of the time using the GPS
Švábeník, Petr ; Šmíd, Petr (referee) ; Vyskočil, Pavel (advisor)
This thesis discusses about using the worldwide satellite system GPS for time and frequency synchronization. This thesis presents study about basic principles of the GPS system, its segments and ways of using this system. Some GPS receivers suitable for receiving the time marks (pulses) used for time synchronization are described. Thesis contents designing of the circuit that will receive time marks and it will digitalize and record external signal and send it with precision time information to PC for displaying and post processing. Thesis also discusses about both hardware and software development of the synchronization module and software used in PC.
