The control unit of the door systems for public transport
Jablončík, Lukáš ; Vlachová Hutová, Eliška (referee) ; Friedl, Martin (advisor)
The topic of my bachelor´s thesis is to design a control unit of the door systems for public transport. The control unit is designed by using modern components. Their availability should be not less then ten years. The unit is controlled by a microcontroller ATMEGA and the motor is switched using the h-bridge. The control unit has ten programmable inputs and two switching outputs. PCB design is optimized for mass production. The result is a functional prototype of control unit.

Adjustable source feeded and controlled by USB bus
Staněk, Miroslav ; Frýza, Tomáš (referee) ; Kolouch, Jaromír (advisor)
The aim of this bachelor’s thesis is concept and realization of voltage source which is controlled and feeded by Universal Serial Bus. There will be presented whole design, execution, development progress and finalization of this project in the following text. This source must boost and buck standard voltage from USB. So it will be necessary using two source lines. Microcontroller of AVR family will be used in the direct part of this adjustable source. Into this microcontroller will be embedded USB interface by the software solution. The microcontroller isn‘t used only for communication with PC by the computer programme, but it is also used for switching the source lines by the PWM modulation. According to the minimum output voltage scale (0 – 15 V) this source is useful for a wide spectrum of low- power devices. This equipment could be helpful together with laptop to charging devices (cell phone, camera, pocket osciloscope etc.), which are carried with notebook for doing outdoor activities and measurements.
