Wireless Tire Pressure Monitoring
Hampl, Tomáš ; Čožík, Ondřej (referee) ; Levek, Vladimír (advisor)
This master‘s thesis describes the design of a system usable for wireless measurement of the tire pressure. The goal is to make a theoretical acquintace with the wireless measurement of a tire pressure. Within the master‘s thesis was suggested device at the block level. For individual blocks have been chosen specific circuits. For the device has been selected the pressure sensor SP100-7AT, the microcontrollers Atmega8 and Atmega16 and the wireless module RFM22. The result of the work is a functional prototype of device including software for microprocessors. Final solution was tested during the experimental measurement.

Oscillometric blood pressure measurement
Brabencová, Klára ; Harabiš, Vratislav (referee) ; Slávik, Vladimír (advisor)
The aim of my work is to propose a meter of blood pressure with oscillometric method using LabView software. To determine systolic and diastolic blood pressure is used detect the maximum oscillation of the envelope signal. The maximum oscillation corresponding to a mean arterial pressure and this value is then calculate systolic and diastolic pressure. In the programming environment of LabVIEW is the signal from the pressure sensor and cuff over the LabPro processed and are calculated limits of arterial pressure.

Analytical workplace for gas valves
Skočík, Pavel ; Havránek, Zdeněk (referee) ; Klusáček, Stanislav (advisor)
This work deals with the measurement of parameters of different types of gas control valves, of a assembling measuring workplace and development of a program for a complex control system consisting of the Siemens acquisition boards and software resources LabVIEW. The program stores the values of inlet and outlet pressure, flow, time or modulation current into a text file. The timing and number of samples can be changed. Outlet pressure versus time or modulation current is displayed on the monitor chart.

Wireless safety appliance
Čapek, Lukáš ; Kováč, Michal (referee) ; Kolouch, Jaromír (advisor)
The purpose of this project is to secure an object, for example bicycle, buggy,merchandise. Protecting device consists of a sensor unit and a pager unit. Both of these units contain a transceiver which works in ISM band. Operation circuits drive microprocessor AVR with low power technology because of possible battery supply. Sensor unit is monitoring the state of sensors and battery discharging. This unit can use accelerometer sensor and two contact sensors. The pager unit indicates alarm, the state of battery in both units and signalizes loss of connection.

Project Pretrigger
Veverka, David ; Pavlík, Michal (referee) ; Háze, Jiří (advisor)
Práce se zabývá návrhem stabilního a rychlého bezdrátového spojení mezi dvěma body. K vytvoření tohoto spojení bude použita technologie Bluetooth a nebo její moderní alternativy vzhledem k tomu, že tato technologie již byla v daném pracovním prostředí testována a byla prokázána její stabilita. V této práci a v navazující diplomové práci budou diskutovány výsledky časových analýz zvolených senzorů, komunikace mezi senzorem a zvoleným mikrokontrolerem a nakonec návrh kompletního řešení, na jehož základě bude vytvořen funkční prototyp požadovaného zařízení.
