Smart accumulator tester and charger
Mílek, Čestmír ; Trmač, Jiří (referee) ; Michálek, Václav (advisor)
Nickel cadmium and nickel metal hydride accumulators sets are currently used for supplying hand tools (screwdrivers,...). Problems of cheap hand tools are chargers, mostly of it doesn’t use any charging driving circuits. In consequence of it the accumulators are kept incorrectly, which causes lowernig of lifetime. This thesis suggest circuit design Main of intelligent charging system, which enable better battery management, increases battery lifetime and lower load of environment.

Industrial building
Michálek, Vojtěch ; Pilgr, Milan (referee) ; Sýkora, Karel (advisor)
In the bachelor thesis a project for steel construction of an industrial hall in Brno area is developed. The extent of the ground plan of the hall is 30x63m with maximum height of 17,300m. The main load-bearing structural elements such as suspended purlin, truss bond timber, noggin pieces, solid-poles forming a cross linking with the bond timber, base and crane runway, are designed and considered in the static calculation. The statement of material and design documentation consisting of the design, cross-section, production drawing of a bond timber and selected details are part of the thesis.

Program for monitor testing
Matyáš, Pavel ; Prokeš, Aleš (referee) ; Michálek, Václav (advisor)
The goal of this term project are problems of LCD panels. The beginning of the term project is about theoretical description of particular types and features of actual LCD panels, origin of picture defects on computer monitors, measuring and picture quality testing methods of monitors. Practical part of project involves designing testing patterns and it's realisation in Borland Delphi development environment.

Control of the communication on the USB
Hlavica, Zdeněk ; Michálek, Václav (referee) ; Prokeš, Aleš (advisor)
The aim of Master’s thesis Control of the communication on the USB is realization hardware and software designed for microcontroller C8051F120 what is enabling recording of data on memory medium Flash drive. It includes study of USB, transfer protocols, which are needed and file system. The thesis deals about host type USB controllers and about USB controller MAX3421E fy Maxim, which has been choosen for development of software. It is required ability to create directories and files including recording data to file and ability of reading data from files in the file system FAT16.

The Roof Structure of a Multipurpose Sport Building
Michálek, Vojtěch ; Šmak, Milan (referee) ; Buchta, Stanislav (advisor)
The topic of the thesis is a project of roof of a multifunctional sport object with a ground-plan covering area 35x48m, and maximum height of 16m. This construction is projected for Brno and its surroundings. The project of roofing is evolved in two different variants. First one is formed by double-jointed arched latticed truss. Supporting components such as purlins, lateral and longitudal bracings, frontal column and anchorage are designed and assessed in static calculation. At the end of the thesis, comparison of both variants is elaborated. Design documentation, which consists of dispositional drawing, drawing of truss for manufacturing, drawing of indicative details and plan of anchorage, is a part of the thesis.

LCD monitors
Kančo, Jan ; Prokeš, Aleš (referee) ; Michálek, Václav (advisor)
LCD monitors brought new problems to plotting of quality of monitors (and visual equipment). Important parameter is response time of LCD monitor. The consequences of nonzero response time are motion artifacts, which are undesirable part of final scene. Response time depends on technology of production and dimension is typical for single technology. Measuring of response time may bring idea of using measured LCD monitor. Rightly response time decides, if monitor is enough “fast” for action video, games, etc, or other parameters are decisive. Producers of LCD panels assign response time which are measured in certain conditions and measured in different ways. The target of this project is designing digital meter response of LCD monitors, but also verification of response times of choice panels.

Voltage convertors for microprocessor devices
Kus, Václav ; Kolouch, Jaromír (referee) ; Michálek, Václav (advisor)
The task of this semester work is carried out summary converters DC / DC power supply suitable for small microprocessor devices with LCD display. As the input source voltage is 9V battery or two batteries (3V). The market has recently appeared a lot of manufacturers of these drives but more detailed information often not available. This work I wanted to help in selecting the correct convertor for your microprocessor equipment. The aim is not to describe all DC / DC converters. Another point of this work is the proposal of two DC / DC converters powered from 9V battery, and two converters fed from two batteries 1.5V. These converters are measured throughout the operating range of output values. This work also contains the documentation for the construction and use.

Measuring temperature inside PC
Rataj, Tomáš ; Kolka, Zdeněk (referee) ; Michálek, Václav (advisor)
This master’s thesis deals with measuring temperature inside personal computer. The main goal of this work is to develop tool which is able to measure temperatures in several places, display a store the values. Theoretical section is concentrated on selection of temperature sensor, that have suitable interface for microcontrollers and has sufficient accuracy for this application. In next part there is complete hardware and software design of instrument. Software solution is based on real-time operating system. Device is projected as a battery-operated compact tool. With created application for personal computer, measured data can be downloaded through USB and displayed in graphic format.

Contactless measuring ventilator-revolution counter
Pokorný, Aleš ; Trmač, Jiří (referee) ; Michálek, Václav (advisor)
This project is about design of contactless measuring ventilator - revolution counter. The counter serves to measurement of the speed of ventilator. The measurement is based on optical method of receiving the reflected laser beam. To measure and calculate use the revolution counter the microcontroller. This measured value is diplayed on LCD. After design follows experimental measurement.
