Implementation of RTOS to the WSN node
Ulianko, Michal ; Kučera, Pavel (referee) ; Pavlata, Karel (advisor)
Bezdrátové senzorické sieťe zväčša používajú `event-driven` operačné systémy. Táto práca diskutuje výhody nevýhody použitia RTOS v bezdrátových senzorických sieťach. Najvhodnejší RTOS je vybratý a sú podniknuté všetky kroky aby bolo možne demonštrovať schopnosť mikrokontrolérov Gecko od EnergyMicro prevádzkovať tento RTOS s nízkou spotrebou energie a demonštrovať jednoduchú bezdrátovú komunikáciu s Atmel AT86RF212 rádiami.

Low Energy GSM/GPRS Module for Sensoric Applications
Pál, Tamás ; Mráz, Ľubomír (referee) ; Šimek, Milan (advisor)
This project deals with the problematics of self-powered universal GSM/GPRS module which is used for sensorical applications. The first part analyzes features of mobile networks and applying energy from the environment. The second section expalins the various parts and characteristic of their associated components together with some fundamental functions of the technology for possible realization of sensoric module. The third part describes plan for system realisation and fourth parth illustrates achiaved results.

Inverter design and control
Starec, Stanislav ; Kozovský, Matúš (referee) ; Blaha, Petr (advisor)
This bachelor's work is focused on description and proposition of solution in the field of hardware frequency inverters for control of induction motors within 100W of output. Based on known information, specified business requirements and the recommendation of the bachelor's work supervisor real hardware components will be chosen. Part of the paper is focused on the assembly of prototype and firmware writing followed by cooperation testing between the prototype and firmware. The end of this work is dedicated to description of communication through digitally isolated interface of USB to PC.
