FLATcon system – CCD detection of media meters with RF communication
Lancz, Michal ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
Bachelor’s thesis deals with designing the concept of battery powered miniature microcontroller system based on CCD detection of media meters. The FLATcon design concept contains the necessary inputs and outputs for communication with microcontroller and with peripheral devices. The aim of the thesis is to detect the state of a media meter equipped with an analogue dial, to save the scanned image along with the scanning time and forwarding through the RF module. The bachelor thesis describes FLATcon system design, soldering and supplying the system and testing peripheral devices.

Reliability of Technical Systems
Jirgl, Miroslav ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
This thesis deals with a reliability of technical systems. It is divided into four main parts. The first part deals with the mathematical description of reliability. Probability and statistics are used for this description. This part includes the definition and properties of random events, the description of discrete and continuous random variable and its distribution. The second part contains the definition and expression of reliability, types of faults in the digital circuits and the reliability of electronic components. This part introduces into problems of reliability. The third part includes making the reliability diagrams and reliability analysis. Each method is briefly described here. Further advantages and disadvantages of using each method are given here. The two most widely used reliability analysis - Failure Mode and Effect Analysis - FMEA (resp. FMECA) and Fault Tree Analysis – FTA are described in a greater detail. The last part focuses on an example of calculation of reliability. An analyzed object is Universal Charger NiMH and NiCd batteries. Reliability is analysed by block diagram, FTA and FMEA.

Accelerometer-based monitoring of steering wheel angle
Navrátil, Tadeáš ; Jirgl, Miroslav (referee) ; Mihálik, Ondrej (advisor)
This thesis deals with the design of a device which will be used for measuring the steering wheel angle. Main goal was to design basic concept of device which is using data gathered from three accelerometers in the reconstruction algorithm to get steering wheel angle. Discussion of various reconstruction algorithms (with regards to simulated output noise levels from acceleromater) and final Implementation of reconstruction algorithm (in MATLAB simulink enviroment) is also part of this thesis. Furthermore, thesis deals with the selection of suitable components. Mainly selection of accelerometers, microcontroller and the selection of a suitable communication bus for mutual communication between them. Thesis also deals with design improvements of algorithm and realization of the whole device. In the end, we compare results of measuring device and inner senzor of steering wheel.

Injection moulding machine prototype
Cikryt, Adam ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This work deals with the design of a prototype injection molding machine for the company Elzaco s.r.o. The work includes theoretical analysis which breaks down injection molding machine into individual components and describes their functionality and their important parameters. Based on the analysis and determination of critical parameters of the injection molding machine, a detailed model of the injection molding machine is created. There are also requirements for electrical components such as motors, power supplies, heaters, temperature sensors, control electronics. The method of controlling such a machine is also discussed.

Application for the HAWK regulator
Kvasnička, Petr ; Štohl, Radek (referee) ; Jirgl, Miroslav (advisor)
This bachelor’s thesis deals with the issue of intelligent buildings management and practical use of the control system HAWK from company Honeywell. The thesis describes the basic problem of intelligent building management, exactly why they created and how it is possible to implement building automation, including a listing of available equipment that can be used in these systems. The thesis also discusses one of the systems that can be used for building control. The control system is called HAWK and thesis describes the programming environment and connectable peripherals. For a given control system is formed in the scrubbing practical demonstration device wind tunnel, which is shown using the work of the control system.

Analysis of car drivers’ behaviour and driving style
Novik, Svatoslav ; Jirgl, Miroslav (referee) ; Mihálik, Ondrej (advisor)
Driving safety remains one of the important issues. Various assistance systems are also implemented, which focus mainly on the analysis of driving and control of the car by the driver. To understand the performance of the driver’s control, a program was created to obtain valuable data and relevant characteristics. To obtain the data, we used an internally designed, laboratory-made vehicle driving simulator. Driver data was measured from the motor vehicle driving simulation, and these were examined and evaluated in the MATLAB environment thanks to integral criteria and other calculated parameters. The obtained values were then used as a training set for the machine learning, using LDA and QDA methods (linear and quadratic discriminant analyzing). This method then provided information on which values are most appropriate and then determines as precisely as possible which driver may be involved in future measures, when this information is not stated in advance.
