Emulation of Character-Based LCD Display Using E-Ink Technology
Rusín, Tomáš ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The aim of this bachelor thesis is to design a simple printed circuit board interconnect. The board is planned to be equipped with a microcontroller that will receive communication signals originally intended for LCD character displays. The communication may be parallel or serial, in the form of SPI and I2C type interfaces. These signals are planned to be received and converted to E-Ink display signals. That display will show information in the same format as it was designed for LCD displays. The E-Ink display replaces LCD displays without the need of changing the original library or the original communication interface. This method of replacement is suitable when a LCD character display is destroyed and a suitable replacement cannot be found, or when the E-Ink display is more suitable.

Effect of acquisition site compression in multisite photoplethysmography
Hofrová, Lucie ; Kolář, Radim (referee) ; Janoušek, Oto (advisor)
The theoretical part of the thesis describes the pulse wave's origin, the principle of photoplethysmography, and the influence of vein compression on the morphology of the photoplethysmograph caused by external pressure during PPG signal measurement. Furthermore, the thesis contains the measurement and analysis of the PPG bilateral signal, which is used for the evaluation of whether there are differences between the PPG signal measured on the left or the right side of the human body. A dataset consisting of 10 volunteers was created for evaluation. The practical part contains the algorithm which analysis the PPG signal. Furthermore, normalization and statistical analysis is performed. The results show that external pressure has an effect on pulse wave width analysis and heart rate. When the pressure is high, the ability of pulse wave analysis is impaired.

Design of linear clock
Firla, Marek ; Malý, Martin (referee) ; Svoboda, Petr (advisor)
The main goal of this thesis is to describe the design, construction, and manufacture of linear clocks. The first part describes the current linear clocks design. The second part describes the design of a linear clock prototype. The linear clock is controlled by an Arduino UNO microcontroller unit, the time is measured by the real-time module, the movement of the time indicators is mediated by a pair of stepper motors. Manufacture is done using 3D printing.

System with RC Model Servos
Kutěj, Jaromír ; Nosko, Svetozár (referee) ; Musil, Martin (advisor)
This thesis addresses the design of a movable RC model with a use of servo motors. It describes both the analysis of suitable hardware and a realization of the project with an emphasis on microcomputer controlled devices and technologies communication technologies with said devices. Furthermore, an interaction a interfacing with user is discussed. Based on findings a system is then implemented in form of a model of a car built atop of microcomputer, controlled wirelessly using a mobile application. This system is then enhanced by proximity sensors that prevent collisions by halting movement of the car.

Mobile robot control system
Bugár, Loránt ; Jílek, Tomáš (referee) ; Hynčica, Ondřej (advisor)
Bachelors project is fixated for creating a mobile robot with a real time operating system. The robot control system is based on a microcontroller Arduino with ARM Cortex-m3 processor. The practical part is dealing with resolving the client-server communication with the UDP protocol, also with the identification of the engine from measured data’s by the Simulink and subsequently designing the PI regulator from the identificated data’s. In he last part of the work the focus is giving to solving the communication with I2C bus and using sensors like : accelerometer, ultrasonic sensor, infra sensor, light sensor, hall sensor and usage of a robotic arm. An application is created for controlling the robot and for visualisation of sensor readings..

Control and regulation of the temperature of the drug transport box
Maťašová, Daniela ; Králík, Martin (referee) ; Sekora, Jiří (advisor)
This bachelor thesis deals with the solution of drug transport in a transport box over longer distances. The work also deals with sensors for temperature measurement and methods of its control and regulation. The essence is the design, implementation and verification of the functionality of the transport device, which allows the display of continuous information about the state of the temperature inside the transport box. Temperature control is powered from the car’s on-board network and temperature sensing is powered independently. The transport device allows the setting of the limit temperature up to 35 °C, while exceeding it is indicated by an acoustic and visual alarm. The transport box, which is the result of the work, allows the transport of drugs, and ultimately meets all the requirements of the assignment.

Infant Movement Monitor
Zahradníčková, Ludmila ; Chmelař, Milan (referee) ; Sekora, Jiří (advisor)
Movement monitor is a detection device for monitoring the frequency of breathing of newborns and infants. It is usually indicated to children under the one year as a support to reduce the risk associated with sleep apnoea and Sudden Death Syndrome. The theoretical part of this bachelor thesis discusses the physiology of respiration, respiratory disorders, methods of monitoring and treatment. The aim of the technical part is to design own monitoring device for detecting and evaluating the frequency of breathing. It includes a block diagram and a wiring scheme of device and a flow chart of program, which is implemented by a microcontroller.
