FLATcon system – CCD detection of media meters with RF communication
Lancz, Michal ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
Bachelor’s thesis deals with designing the concept of battery powered miniature microcontroller system based on CCD detection of media meters. The FLATcon design concept contains the necessary inputs and outputs for communication with microcontroller and with peripheral devices. The aim of the thesis is to detect the state of a media meter equipped with an analogue dial, to save the scanned image along with the scanning time and forwarding through the RF module. The bachelor thesis describes FLATcon system design, soldering and supplying the system and testing peripheral devices.

Embedded System with Communication Interface NFC and Wi-Fi
Bugár, Loránt ; Valach, Soběslav (referee) ; Horák, Karel (advisor)
This master’s thesis deals with communication system design via the NFC and Wi-Fi interface. The thesis has two basic goals. The first goal is to create a device that is capable of storing of data and its subsequent transfer via the NFC interface. The second aim is to utilize this device for measuring various physical variables. The IoT technology is employed to fulfill the aforementioned goal. IoT technology is capable of visualizing data in real time and make them accessible via the Internet. The result of this work is an universal device, that contains the most popular communication interfaces, such as I2C, SPI and that is capable of processing measurement data from digital, analogue, and wireless sensors.

Smart charger with cell identification
Alechko, Ivan ; Harvánek, Michal (referee) ; Kubíček, Michal (advisor)
Cílem bakalářské práce je zvolit vhodnou metodu pro identifikaci jednotlivých akumulátorových článku a vybrat vhodný způsob jejich nabíjeni. Ze zvažovaných metod identifikace jsem vybral jako vhodnou technologii RFID. V práci je popsán princip identifikace včetně konkrétního návrhu pro následující realizaci funkčního zařízeni. Část práce je věnovaná problematice nabíjeni akumulátorů. V této části je detailně popsán charakter nabíjeni článku v závislosti na jeho chemickém složeni. Pro realizaci (demonstraci funkce) jsem zvolil technologii nikl-metal hydridových článků (Ni-MH). Důraz jsem kladl na bezpečné a zároveň efektivní nabíjeni. Dalším úkolem bylo navrhnout metodu dlouhodobého sledování stavu akumulátorů v průběhu více nabíjecích cyklů. K tomu bude sloužit mikrokontrolér, který bude pro každý článek zaznamenávat údaje o nabíjecím cyklu.

Cyklocomputer with Frequency Meter
Netáhlo, Tomáš ; Fedra, Zbyněk (referee) ; Hermany, Jiří (advisor)
The Bachelor’s thesis deals with design and realization of the cyklocomputer with a measuring frequency of pedaling. The device measures speed, pedaling frequency, heart rate, distance traveled and the current time and date. Measured values are stored in memory and then can be transferred via USB bus to computer. The work includes a description of the magnetic sensors and ECG sensors. The practical part includes the design of hardware and software cyklocomputer.
