In present days there is no scientific laboratory without quality, adjustable and powerful source of voltage and current. Therefore this thesis is focused on creating such power source, which can provide voltage and current high enough for most of experiments or for development electrical devices or parts, which are not connected to power grid. This power source is able to provide symmetric voltage 30 V and current 6 A high in each branch. It is possible to control this power source remotely thanks for USB interface, which is standard equipment of majority of modern devices in these days. LCD display is part of this source, which shows the user set and real parameters at the output as well.

This diploma thesis is a part of HUMMER project. The project deals with three student’s development of two-wheeled unstable vehicle Segway type and its diminished laboratory model. This thesis deals with reviviscence of laboratory model, design of its control and realization of its actuating (a more detailed breakdown of tasks in the project is shown below). At the beginning of the work is presented reviewed study. The first part of study deals with similar models in the world, their construction and way of control. In the next part of reviewed study follows description of a real model and derivation of model basic equations, in the last part of search is given principle of operation of some used sensors. The next step was the selection and design of required electronics. In this capture are described all designed electronic modules and used sensors. There are also given parameters of used batteries and motors. The next task was the estimation of system parameters. The estimation was made by sections, in the capture is in detail described way of measuring data and structuring of estimation model. The penultimate step was design of PID and LQR controller using I/O card MF 624 and their comparing. Following thing was choice of better regulator and its implementation to the microprocessor. The last step was the realization of actuating driving of model by joystick and supreme PC.

The diploma thesis focuses on optical fiber sensors with detailed preview of the turbidity sensor, its design and testing. The introduction deals with the general theory of fiber sensors and measurement methodology of physical variables. This part is followed by a charter focusing on the possible ways of measuring turbidity. Furthermore, the diploma thesis introduces design of the new turbidity sensor which is realized with consideration of the industrial usage and future application to the automated process of beer production. It also includes a detailed description of the hardware and software sensors created within this thesis. The last section is devoted to a calibration and testing functionality of turbidity sensor.

The aim of this work is to design a microprocessor-controlled multimode VHF radio can receive AM, FM and DAB. The first step is to become familiar with digital radio broadcasting DAB and RDS. Then we can proceed to the design of the receiver circuit solution using modern component base. Next it is necessary to write utility software and construct a prototype of receiver, verify its functionality and parameters. The result of the work is the multi-mode VHF broadcasting receiver controlled using touch screen display and supported by web management.

This Master's Thesis is focused on the design and control of a small-series production line, for the production of segmetal arches and plastic reductions. It is about the conversion from a semi-automatic line to a fully automatic line. The production line consists of an extruder, a cutting unit, a exhaust unit, three pressing machines and a manipulator. Every single machine has a custom control for which was selected a baseplate with microcontroler ATmega 128 and designed powerful part of inputs and outputs. There is a simple communication between the machines. Appropriate elements were used for conversion of every individual part of the production line. The whole system is programmed with software called AVR Studio4.

Diplom work describes a proposal and the design of the device for controlling the temperature test in a climatic chamber Heraeus and the creation of software for operating equipment. Work describes in detail the design and construction interface for the climate chamber, with which will be able to run automated test sequences and the development of the firmware and the operating software to start the temperature test.

The Master's thesis Transformation of the microprocessor's description language to the hardware description language is aimed at design of application specific microprocessors with using ISAC language. It deals with design and implementation of transformation which converts description of microprocessor in ISAC language into equivalent description in VHDL language. The chapter Summary of research problems describes chosen problems, showing up some notions connected with problems and presents suggestion of transformation mentioned above. The chapter Suggestion of solution presents new extension of ISAC language. There is also described the way of design solution of transformation and solution of implementation of VHDL generator which performs transformation. Conclusion of thesis discusses next points of future work reached results.

The aim of this project is to describe, design and create a converter from 12V DC to 230 VRMS. The power of this device is about 500W. The device consists of two main converters. The first one is step-up DC/DC converter and the other is DC/AC inverter. Step-up converter is designed as a resonant converter. It is useful for pushing down losses in semiconductors and inceasing efficiency. The inverter is changing DC voltage from the first converter to AC voltage. Control of this device is realized with DSP Motorola. This device should be used mainly for supply common devices up to 500W. Main usage is planed in a car or to another place where is not posible to connect some device to plug.

The aim of this thesis was to design a concept and circuit for multifunction display. This unit is used in ground power supply for preflighting preparation of army helicopters. Multifunction display measures voltages and currents of AC and DC generators, teperatures of cooling air and fuel quantity. Display indicates a operational and fault states of ground power supply. The main element of multifunction display is 32-bit microprocessor from the manufacturer NXP, family ARM7. All information are displaying on graphic vacuum fluorescent display GU256x128.

This diploma thesis deals with the design and construction of a three-axis CNC machine primarily designed for PCB drilling and production of front panels for various electronic devices. All three axes are driven by stepper motors NEMA 23 which are connected to stepper motor drivers L6470. Processor STM32F407 is used to control the whole machine. The wiring is completed by a LCD display with touchscreen which is used to communicate with user. Data for drilling can be entering manually or via USB inerface. Part of this thesis is the selection of a suitable construction and components, assembling equipment, wiring design of electronic circuits and writing the code to control the machine. Finally, the parameters of the designed device have been measured.
