Design of Acoustic Emission Detector
Velecký, Petr ; Křenek, Ladislav (referee) ; Rubínová, Dana (advisor)
This bachelor thesis deals with design of acoustic emission detector, a professional device for leak detection in pneumatic systems. The aim was to create an intuitive device that would have a distinct appearance and respect all ergonomic, technical and aesthetic requirements. Manipulation with the device was made easier.

Design of system for indication of gas leakage by ultrasonic microphone
Bohuš, Michal ; Kovář, Jan (referee) ; Šotner, Roman (advisor)
The aim of this project is detection of gass leak based on the ultrasound sensing. Work introduces ultrasound, mechanism of its propagation and attenuation. From all of the available microphones, the piezoelectric microphone was chosen. Project continues with description of the device, which can be capable of detection of the ultrasound leakage in dangerous, explosive environment. This type of device must meet requirements of SIL 2 standard and ATEX directive for zone 2. Project discusses LNA (Low Noise Amplifier), filters and detection circuits design. The device is modular what means that each module can be freely replaced. The role of these modules is to convert analog signal to digital form suitable for microcontroller HERCULES TSM57012.
