The purpose of this thesis is to show up possibilities of inter-vehicle communication and to introduce new approaches in communication for the purpose of enhancing the security and the fluency of vehicle transportation. This thesis also highlights vulnerabilities in communication. The main goal is the analysis of existing technology and the design of protocol for data transfer with focus on minimizing handover time of informations. Part of the design is a simulation of communication based on acquired information.

The work deals with the implementation of the specific architecture to detect anomalies in the classroom or in commercial use. The system consists of three parts: Measurement module, mobile applications and server part. Transmission between the measuring module of the server and the evaluation is carried out simultaneously with the visuals on the mobile device. All system components are implemented with the minimum cost and maximum expandability. All the necessary computing power is concentrated in the server part because of usability with multiple simultaneously operating mobile clients. Emphasis is placed on the solution architecture and the possibility of using the system as a whole, or selected portions separately. Finally, experiments are designed for the presentation of selected methods for anomaly detection.

The aim of this thesis is to study the possibilities of controlling high-brightness white LEDs using circuits operating at high voltages. The job itself is a division of existing light sources and mainly focus on semiconductor technology LED. The following describes the voltage of DC / DC and AC / DC. The work contains a description of the three high-voltage inverters are designed for power LEDs. Finally, it created a draft scheme of the PCB. As a control circuit is chosen ATMEGA 162 microcontroller from Atmel and source for LED diode is formed HV9910 and HV9861 circuits.

This dissertation deals with a development of MCU position steering application of two servomotors and with data process evaluation from a connected sensor for distance measuring as well. The connected sensor is adjustable as for azimuth and elevation. Data from the sensor will be useful both for instant evaluation according to preset criteria and for additional possible processing at PC. The development is to be carry out at MCU ATmega128. HMI is represented with keyboard, LCD and joystick. The result of the dissertation is to be adjusted for practical demo. This research has been supported by the Czech Ministry of Education in the frame of MSM 0021630529 Research Intention Inteligent Systems in Automation.

This master's thesis deals with application design and implementation of secured communication between smartphones. Analyses issues of cross-platform portability between operating systems, its differences and common features. It shows an overview of Android OS architecture and its individual layers. Thesis describes basic principles of secured communication in the modern cryptography and implementation of application for mobile platforms. Also shows an overview of modern mobile technologies such as NFC (Near Field Communication) and Bluetooth. This thesis reveals basic architecture and the way how it fits into concept of secured communication. It also describes the architecture of application and concept of secured communication, which is then implemented. In conclusion is summarization of achieved results and possible extensions of implemented application.

This master’s thesis deals with a modification of existing project which is used as a helpful tool for tracking and measuring digital audio interface I2S. The original design was created by Ing. Martin Stejskal, Polymorphic USB – I2S Interface. Modifications are based on practical one year experience when the device was tested and deals with new requirements for extension. This work describes and justify individual changes of hardware and software part of project.

This thesis deals with the safety of wireless networks and used protocols. The aim is to describe chosen network attacks and demonstrate the feasibility of using the device Pwn Phone. It will also be implemented a system consisting of a mobile application and a server component allowing execution of NFC relay attack on contactless credit cards. System will be tested in real world and evaluation of the success in different conditions will also be part of the thesis.

This thesis is focused on the design and realisation of inertial navigation unit INS. The unit is capable to measure, store and send data to a PC in real-time for a later offline processing. The first part of the thesis introduces the reader with the basic principles of accelerometers, gyroscopes and MEMS sensors. An introduction to coordinate systems and measuring errors is also included. The second and third part of the thesis deals with the analysis of the solution and the implementation of the INS unit. The fourth part of the document is dedicated to the software for the INS unit. This thesis concludes with explanation how the gathered data are processed.

This thesis deals with creating a library for the Android OS which enables efficient wireless communication with platform Arduino. The target is to create an application for Android OS, using a created library that allows you to capture data from various sensors and control effectors. The work describes basic wireless interfaces for Android OS and Arduino platform. The main benefits and drawbacks functions are also introduced. The comparison of current consumption for modules HM-10 and DIGI S1 has been carried out as well. Possibility of data acquisition and effector controlling exercises have been tested and verified.

The indoor positioning system is a series of networking systems used to monitor/locate objects at indoor area as opposed that of GPS which does the same at outdoor. The increase in the popularity of the Internet of Things made the demand for Bluetooth Low Energy technology more and more essential due to their compatibility in the smartphones which makes it to access easier. The BLE’s reliable signal and accuracy in calculating the distance has a cutting edge on others in IPS. In this thesis, the Bluetooth Low Energy indoor positioning system was designed and implemented in the office area, and the positionofIoTdevicesweremonitored. OntheIoTdevices,thebeaconswereplaced. And thesebeaconswerecoveringtheofficearea. Thereceiver,smartphoneinourcase,recorded theReceivedSignalStrengthIndicationofthetransmittedsignalsfromthebeaconswithin the range of the signal and stored the collected data in a database. Two experiments have beenconducted. Oneisforbeaconsthatarestationaryandonethatismoving. Toevaluate these experiments, a few tests were performed to predict the position of beacons based on therecordedreceivedsignalstrength’s. Inthecaseofstationarybeacons, itoffersaccuracy range from 1 m to 5 m, and 3 m to 9.5 m in anticipating the position of each beacon in the case of moving beacon. This methodology was a mixture of fingerprinting and an algorithm of multilateration. Finally, the experiments show that the algorithm used provides the most accurate indoor position using BLE beacons that can be monitored through an Android-based application in real-time.
