Ambulatory ECG Holter Monitor
Majerík, Peter ; Strašil, Ivo (referee) ; Číž, Radim (advisor)
The thesis deals with design of the device for monitoring four signals from the probes for scanning ECG, PPG and heart pressure. The thesis is mainly focused on hardware design of the device and the most important part is the selection of the storage media to which will be the data recorded and the selection of the microprocessor which has to be able to meet the requirements of the device. For the data recording is used SD card and the ARM based MCU was selected from the AT91SAM7S series. This thesis also deals with the software design for MCU which is needed to launch the device and with design of PC applications used for setting the device and for downloading the measured data. At the end there are presented results of the constructed device.

Wireless doorbell with digital voice transmission
Partsch, Patrik ; Šebesta, Jiří (referee) ; Mikulka, Jan (advisor)
The master´s thesis deals with a design and layout of wireless doorbell with digital voice transmission. It also includes the nRF9E5 circuit analysis. In the beginning of the document there is characterization of the problem in general. Next part describes a layout example for the application schematic, a layout of printed circuit board and a layout of software. nRF9E5 is a true single chip system with fully integrated RF transceiver, 8051 compatible microcontroller and a four input 10 bit AD converter. Despite of all studies of available literature I have found only very little particular information related to this matter. In general, the main aim of this work is to make the wireless doorbell with digital voice transmission. Further, ilustrated schematics are enclosed as a attachement of this thesis.
