Wireless sensoric network for hop drying facility
 Čapek, Lukáš ; Čech, Jakub (referee) ; Šnajdr, Václav (advisor)
The purpose of this project is to build a wireless sensor network for measuring temperature and relative humidity in hop drying facility. This is a monitoring device, consists of several sensor units and one control and display unit. Display unit coordinates a whole network and can display data on LCD or download collected data to PC. Sensor unit measures a relative humidity, temperature, battery voltage and transmits data to display unit. Units contain a transceiver which operates in ISM band 868 MHz. Circuits are driven by 8-bits microcontroller Freescale.

Cardiotachometer
 Čech, Jakub ; Sekora, Jiří (referee) ; Čech, Petr (advisor)
Master’s thesis deals with theme of heartbeats. Monitoring and evaluation of heartbeat is important for diagnostician cardiac dysfunction. First part of thesis is focused on anatomical description of heart and his operation. Another part is description of electrical activity of the heart and methods of capture. There is also mention of the cardiac rhythm and its disorders. One of the principal objective of this thesis is to study methods for sensing heart rate. These methods are analyzed and then selected a particular method for further solutions. The core thesis is to design functional cardiotachometer. Cardiotachometer derives the heart rate signal from phonocardiographical signal, which is acoustic manifestation of heart. Implementation takes place in the Labview, which is graphical programming environment. Suggested the device measures the current and average heart rate and the addition of HRV analysis in time domain.
