This master’s thesis focuses on the possibility of using contactless smart cards as an electronic hiding place in an activity known as Geocaching. The first part explains the theoretical knowledge about cards, smart card programming, the development of android applications for communication with the smart card using the NFC interface and usage of eliptic curves to sign digital messages. The second part is dedicated to the design of a Java card application and an Android application, which are able to communicate

The access system with the Ethernet interface is presented in this diploma thesis. Access control system is based on the RFID technology. Each identification unit reads the users card number and sends the request to the server other the network. Server checks the card number and sends the answer. The doors are opened. The first part of this diploma thesis deals with the theoretical description of the access control systems. All used technologies are described in this first part of this work. The second part of this thesis describes hardware design of the RFID identification unit with the Ethernet interface and microcontroller Rabbit. The last part presents designed communication protocol. This protocol supports AES secure communication standard. The control program of the identification unit and to the software design of the database and the server application is made and described in this work too.

Master's thesis analyses modern hash functions. The requirements for these features and briefly outlined some of the types of attacks are given in the first part. The second part focuses on the specication Skein hash function, which is among the candidates for the new SHA-3 standard, and a description of the JCOP platform, which is a function implemented. In the last part of the work there are discussed implementation problematic parts and evaluation of the selected solution.

This thesis focuses on the measurement with the help of sampling cards and determination of the basic parameters of the measured signal. There will be described basic characteristics of the used card Alazartech ATS860- 256M and brief description of the programming languages which will control the cards. In these environments there were the created driving programs for the operation of these cards. Main measuring program was created in the language C\C++, that shall work as oscilloscope and the same time as spectral analyzer. This programme will determine basic characteristics of the measured signal. Further there will be created simple preparation for memasuring with this card. In the conclusion of this thesis will create instrutions for laboratory exercise.

The aim of my master‘s thesis was design of analog measuring card with generator and Ethernet interface, based on RCM3200 Rabbit Core module. I described this module, introduced the conception and the design of the measuring card. In appendix I stated design of schematic, design of board. I tested functionality of the measuring card.

The task of this master´s thesis is to write a theory of radiation sensing, describe the function of GPS and design the measuring system which can measure the radioactive background and these values assigned to the current GPS coordinates.

The work deals with the 32-bit microcontroller with AT91SAM7X256 ARM7 core. The overall purpose of the thesis is to use the microcontroller as a data logger in Orpheus robotic system. The main part of the work focuses on detailed description of the designed board, software and development environment. A comparison of different varieties of the microcontroller with this core is included.

This thesis is about construction of a monitoring unit for motor vehicles. The unit is equipped with microcontroller, graphical LCD for displaying all measured values, GPS module and SD card slot. For measuremet of motor RPM, various methods of connecting to the motor are supported. Temperature is measured with few DS18B20 sensors, picking up engine temp, outsider and inside temp. GPS module is for measuring speed and height above MSL. All measured values can be recorded on SD card for future analysis on PC.

The thesis deals with design of the device for monitoring four signals from the probes for scanning ECG, PPG and heart pressure. The thesis is mainly focused on hardware design of the device and the most important part is the selection of the storage media to which will be the data recorded and the selection of the microprocessor which has to be able to meet the requirements of the device. For the data recording is used SD card and the ARM based MCU was selected from the AT91SAM7S series. This thesis also deals with the software design for MCU which is needed to launch the device and with design of PC applications used for setting the device and for downloading the measured data. At the end there are presented results of the constructed device.

The work deals with the registration of incoming patients to the physician. In the theoretical section summarizes the current technical solutions used in practice to record the waiting clients to provide various services. One chapter is devoted to describing the identifiers occurring in the population. The result is to design a custom solution based on reading data from health care cards.
