The remote control workplace of electrochemical sensors
Cieslar, Jakub ; Šteffan, Pavel (referee) ; Adámek, Martin (advisor)
This master’s thesis deals with the design of automated workplase for measurement with electrochemical sensors. Design and realization of a device, which communicates with computer and which can be controlled via WAN or LAN nets, are the main aims of this work. This thesis describes the process of designing, realization and optimalization of designed preparation adjustment. It also describes created software of a device, driver for service PC and programme of a web client.

I/O Card Controlled by SMS
Bachtík, Martin ; Pavelka, Ondřej (referee) ; Orság, Filip (advisor)
The aim of this bachelor's thesis is design and implementation of a universal device with input-output character. The device detects incitations on few inputs and sets few outputs. The user controls the device via SMS or short multiple dialling. The device interacts with the user via LED diodes, SMS or hort multiple dialing.

System for position monitoring
Brouček, Jan ; Younes, Dina (referee) ; Šteffan, Pavel (advisor)
Bachelor's thesis contains design of device that is able to determine its own location by the GPS. Detected location data are stored on the memory card microSD and they are optionally posted on the web server via the GSM network. Data are stored in GPX format, ensuring the compatibility with commercially available programs and devices. Planed usage of device is for informational tracking of moving objects, or as a car security feature, which can inform user about car position.

Universal switch for security systems
T.Kovács, Matúš ; Fedra, Zbyněk (referee) ; Frýza, Tomáš (advisor)
The aim of this work is to discuss the topic of a secure technology device using an electronic securing system and a camera system. The device is using four cameras, from which each is connected to a motion detector. The device is designed so it allows the recognition of a possible failure to the analyzer, damage or arcing fault of the guidance, the switch of the video signal within the vertical blanking interval, or a malfunction of the SMS sending from a GSM modem. Important parts of the device are the VIDEO MUX, which provides the signal from the camera to the screen, and the PIR HANDLER which detects the states of the PIR detector. The work of these peripheries is monitored by the ATmega128 microcontroller.

Design and Implementation of Small-lot Production Line
Šíl, Petr ; Vdoleček, František (referee) ; Zuth, Daniel (advisor)
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.

Testing and charging of accumulator cells
Sršeň, Jan ; Kubánek, David (referee) ; Lattenberg, Ivo (advisor)
Direction of the master's thesis is design and construct electronic device for testing available accumulators. Than there are in detail subscribe some metods of charging cells and their right usage to select type of cells. Also eventually problems that can become if the choice is false. Next part contains description of principles as several type accumulator works and their loading characteristic witch are important know for choose the best testing way. The most important knowledge is detection of stop point charging when accumulators are charged and following charging can be dangerous. Because there are more methods to detect this point so in thesis are overwrite. The most important part is design of tester. That is mapped to more segments witch communicating together. Controller part of intelligent tester contains ATmega128 microcontroller so there is present a passage of program code. Last section of master's thesis describe a physical consruction and explain division for smaller parts and hole process of tester function.

Multifunction board computer for motorcycles
Netáhlo, Tomáš ; Tošovský, Petr (referee) ; Brančík, Lubomír (advisor)
Master’s thesis deals with a design and a realization of multifunction board computer for motorcycles. The goal of the device is measuring speed, rotation speed of engine, temperature of ambient, temperature of engine, temperature in intake including signalization of overvoltage and hightemperature. The device is completed by above standard function such as measuring titl of motorcycle, climbing of route, route recording and data transmission to the computer. The thesis includes a complete solution of hardware and software part of the device.
