This diploma thesis is focused on testing ECG monitors and ECG instruments. There are discussed origin and charakteristics of ECG signal. The ECG signal is presented by standard leads. This is the reason, why the way of making leads is mentioned. One chapter is aimed at generating ECG signal. There are set requierements for the ECG generator. These requierements results from ECG instrument possibilities and from ECG signal character. Next part of this diploma thesis includes hardware design of each part of the system. The system was designed with respect to mobility and 12-leads systems compatibility. Finaly the thesis includes design of the controll software.

The concept proposal of the RFID security terminal is described in this Master Thesis. The RFID identification and its usage are analyzed at first. The description of the selected fitting circuits, communication bus as well as its parameters follows. The practical realization, proposed module design and designed printed circuit board is described afterwards. Several problems found during activation phase are analyzed in the chapter describing the practical module realization. The problem resolution is mentioned as well. The practical prove of the real module parameters and differences compared to the designed values are described at the end of this Master Thesis.

Diploma thesis is focused on principles of measuring the vibrations using accelerometers and using them for making vibration measuring instrument with focus on modern integrated digital accelerometers. In the first part are described ways to measure acceleration and vibrations with available technical supplies with respecting place and purpose of measuring. In practical part are measured characteristics of used sensor, instrument for measuring vibrations is designed and built and for few experimental object vibrations or acceleration are measured and graphical interpreted.

This article describes AVR Wizard programme that was developed for AVR Studio. This software simpliefies microcontrollers (MCUs) programming in a way of general peripheries settings and registers settings for varied MCUs. AVR Wizard is able to generate C language-based MCU main programme structure with chosen settings. User-friendly handling and no longer detailed studies of MCU datasheets are also main advantage.

The main goal of this work is to design an efficient and cheap car-alarm with an electricity consumption not exceeding 1mA in the stand-by mode. The first part focuses on the conception of the car-alarm. As the best option - GPS/GSM car-alarm conception is chosen. Then the design of the switching power supply, communication via RS232 with the GSM module, and GPS module, I2C communication with accelerometer and timer IC, and design of the display module are described. Furthermore, the process of how to code/decode sms into the PDU format is also discussed in this part. The second part provides some basic empirical characteristics of the switching power supply (efficiency, switching frequency etc.). Then the owchart of the main loop is explained, followed by an example of the sms which the car-alarm sends in case a car theft. Explanation of how to set up timer, acceleration threshold and the time between the check of the sms commads is the subject of the next section. Fifth part deals with the installation the car-alarm into a car which is illustrated on the Skoda Favorit example. Total costs and also different cost items are listed just before concluding and suggesting some potential improvements of the device.

The main target of this work is to design and to implement unfailable safety appliance for motocycles with use any GSM technology. In my masters’s thesis I applied to individaul fields which I had to knows for realization of this work. The introductory chapter tells the reader about evaluation of former semestral projects and about brief description of the realized mechanism. It is followed by descripctoin of principles of communication between PC and mobile phone. The main part of my work is dedicated to application itself. The applicaton is called motoalarm. The last chapter creates description service of localisation mobil phones which is called Kde je... The conclusion includes evaluation of this master´s project and general description of the realized mechanism.

In first chapter I introduce with aim of diploma work and in second chapter with principles distance measuring in robotic. After it in next chapter I describe used distance sensor, his principle and characteristics. In fourth chapter I describe control and parts mechanics shoulders. The fifth chapter describes program, which control mechanics shoulders by the 32bits microcontroller Freescale. At last sixth chapter gained data are modified and resulting imagery in 2D and in 3D.

This thesis deals with principles of measuring of acceleration with commercially available accelerometers and theoretical analyses of measuring of angular speed of rotational motion. Then the proposition of application’s connection controlled by microprocessor and software solution with implementation of serial communication interface is described. The function of the apparatus is examined with experimental measuring and elaborated protocol.

The content of this thesis is to create a detailed description of 32-bit ARM-based processors. Reader will be inform about the each one of the family of ARM-based processor, about the options of creating applications for these CPUs. The Applications are commonly developed by using the C/C++ language. This text also deal's with the development environments. These tools are making easier the development of new applications. This thesis also contains a complete design and description of development board with Atmel AT91SAM7S64 MCU (with sample of source code included).

Subject of this thesis is introduction to questions of stepping motors control. The thesis characterizes basic principles some types of stepping motor, their features and control methods. These knowledges are consequently used for proposition of controlling circuit for driving stepping motor using microcontroller.
