Intelligent Control Using Hand Gestures
Apjar, Martin ; Hyrš, Martin (referee) ; Šimek, Václav (advisor)
This work deals with a creation of the device suitable for capturing the gestures of the human´s hand, selection of suitable sensors, creation of service software and communication proposal. The device working is based on Arduino board with microprocessor from the company Atmel ATmega32u4. In the first part of the thesis a detailed search of the existing ways of solving the given problem was performed. The following sections are devoted to the design of my solution, the description of the fabrication of the model body and the description of the used materials. Further, the Thesis contains a description of all sensors and scanners and a detailed description of the supplied PCB. At the end we will find the program section where the control and sensor work is disassembled. The result of this work is a hand-held model and firmware.

Solar charger with embedded accumulator
Háněl, Petr ; Dušek, Martin (referee) ; Kubíček, Michal (advisor)
The mobile devices are under rapid development today and thereby they put still more challenging requirements on charging technologies. The thesis deals with design and development of an off-line charger device for travel use. It is based on an accumulator that is being charged continuously using a solar cell. Alternatively the accumulator can be charged using a standard USB port. One of the key requirements on the device was simplicity of its circuitry in order to make the device cheaper and more reliable. The device is able to supply any mobile device that is using a standard USB port.

Smart Li-ion Batery
Prachař, Vojtěch ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
The thesis deals with lithium accumulators with electronics, which are composed to a unit called Intelligent Battery. Within this thesis, the main features of these accumulators are explained and the circuit to monitor these accumulators has been designed and manufactured, it can disconnect them when the parameters are exceeded, and it stores the history of the battery measurement in memory. It also allows reading of current and logged battery data via UART. The computer application is designed for communication, to display the information and to adjust the battery circuit parameters. The electronics secure charging when the 24V adapter is connected according to the set parameters and it also secure balancing of the individual accumulators.

Backup power supply with solar panel charging
Křepela, Pavel ; Götthans, Tomáš (referee) ; Kubíček, Michal (advisor)
This project aims to create a backup power source with solar charging for small mobile devices (through USB connector). The charger should store power in a battery that is charged either from external power source or the solar panel. In the introduction, the work deals with the theory of solar cells and batteries. Furthermore, it described the selection of suitable components and design diagram.

Backup power supply with solar cell
Hrubý, Michal ; Brančík, Lubomír (referee) ; Kubíček, Michal (advisor)
Due to the modern trends of energy production from renewable sources, this thesis deals with backup power powered solar cell. Analyzes the principle of operation of the solar cell, describes its technological development. Describes types of commercially available accumulators and their specific properties and the recommended charging. It then focuses on the description of the activities used DC-DC converters and their specifics. The aim of this work is to construct a backup power device that uses USB, independent of the electric distribution network.

Processor controlled backup power supply
Hořák, Jan ; Štraus, Pavel (referee) ; Kubíček, Michal (advisor)
This thesis describes the design of a processor controlled small battery backup power supply. The aim is to design a device which can recharge many kinds of mobile devices with a battery capacity up to 2Ah. The main control element is a microprocessor that records operating data of the power supply and stores in onto an SD card. Portability and durability were taken into account during the design. The result is completely designed and build a backup power supply, including program for its microcontroller.
