Wireless Messaging System
Musil, Tomáš ; Dlouhý, Jiří (referee) ; Sekora, Jiří (advisor)
The aim of thesis is a design of wireless pager, that can be used for short text messages transmission from the sender to a particular recipient. The report is sent from a computer via serial port. The application is based on microcontrollers, which provide data protection, evaluation and display data on the display of the receiver. The wireless transmission is effected via the RF modules, that are powered from batteries.

Monitoring of persons in an enclosed space
Rivolová, Kristýna ; Kolářová, Jana (referee) ; Sekora, Jiří (advisor)
This diploma thesis deals with monitoring of persons in an enclosed space. The goal of this thesis is to get acquainted with the issue of indoor localization and the subsequent creation of own solution using the ultrasound technology. Ultrasound technology should eliminate some deficiency of current technologies. The theoretical part includes the overview of some current methods. Last part of the thesis verifies the function of device.

Microcontroler based ECG Generator
Ruttkay, Michal ; Bubník, Karel (referee) ; Sekora, Jiří (advisor)
This thesis describes the design and realization of the EKG generator which uses a microcontroller in order to generate the EKG signal. The EKG generator is equipped with one input and two outputs for recording the signal on the oscilloscope. The LCD display shows the heart rate that can be changed by means of buttons. In addition to the design and realization of the EKG generator, the thesis describes cardiac activity for the proper conduct of EKG signal as well as the flowchart of the program for the microcontroller.

3D dental scanner
Kotek, Lukáš ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
The general aim of my master´s thesis is to study the actual principles of 3D scanning, the anatomy of human teeth, use of 3D scanning in dentistry and other medical fields. Another part of this thesis is about software and hardware design of 3D scanning system, which enable us to scan dental casts. This design is using webcam, projector and turntable. The principle of scanning is based on the activ triangulation. The output of 3D scanner is a horde of spots, which are used for reconstruction of a surface. The reconstructed surface is finally saved as .stl format.

Classification systems in the hospitals
Valla, Radek ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
Classification systems in health care in the Czech Republic come increasingly to the fore when billing for services provided by hospitals. This work presents a review of classification systems and is focused on systems dealing with economic demands of hospitalization (DRG) in Czech Republic and abroad. In the Czech Republic, hospitals are working with IR-DRG system; therefore it is discussed in a separate chapter. The work also includes design of web application using technologies from InterSystems. The application serves as a module of the hospital information system Clinicom to calculate hospitalization rates by classification into the DRG.

Flight properties of discgolf disc
Valík, Tomáš ; Sekora, Jiří (referee) ; Hanák, Petr (advisor)
Even through the rising popularity of disc golf all around the world, there aren't many solutions on how to compare individual throws, other than by observing. By placing inertial sensors on the bottom plate of the disc, an average rotation frequency was obtained by an algorithm. By comparing six methods of evaluation with reference values measured with the Qualisys system, the best method returns an average percent error of 2,66 %. Based on this result a test comparing two throws, backhand and forehand, was made, with average values of 14,22 and 11,46 revolutions per second. Two sample t-test rejected null hypothesis at the 0,05 significance level with p-value 2,101*10^(-18).

Analysis of accelerometric signals during gait cycle
Nemčeková, Petra ; Sekora, Jiří (referee) ; Králík, Martin (advisor)
Kinematic analysis of gait is one of the most important examination of lower limbs. One of the possibilities of this analysis is measuring by accelerometer. This thesis is focusing on construction of a functional device, which measures an angle of ankle, hip and knee joint during gait and developing application, which enables measurement and displays measured data. Results from device were compared with kinematic norm used in ortopedy.

Feedback for active hand prosthesis
Trajlinek, Jan ; Sekora, Jiří (referee) ; Harabiš, Vratislav (advisor)
This thesis deals with the solution for feedback of active prostheses to ensure that it is as similar as possible to the biological somatosensory system, and at the same time to prevent any limitations to the patient and provide the patient with as much useful information about the sensual touch as possible. With regard to these factors, the system for the detection of forces acting on the limb and the subsequent transmission of this signal to the user´s limb is proposed. This system is designed particularly for an already constructed prosthesis manufactured by Ing. Štěpán Brázdil within the diploma thesis from 2020. The thesis describes the biological response, on which all substitutive and artificial responses are based on. The thesis then further describes these substitutive and artificial responses and aims to find solution, how the biological response can be more or less replaced.
