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.

FM Transmitter of APRS Telemetry in 144 MHz Band
Bohátka, Jan ; Šádek, Václav (referee) ; Urbanec, Tomáš (advisor)
APRS system is described are sent toin my essay, which is used for sending and receiving text messages. The text messages frequenc 144 MHz by using the modulation scheme AFSK. APRS communicate by using the protocol AX 25, which sends and receives the text messages in the area where are carried despatches and control bits as well. The whole area of high frequency part is in one integrated circuit. The control, coding and decoding of the area is the microcontroller’s job.
