Automatized working place for measuring of airflow parameters
Smělý, Jakub ; Vejlupek, Josef (referee) ; Vlach, Radek (advisor)
This thesis describes the design work for the measurement of air values. The first part describes the airflow, pressure build-up in pipes and losses due to airflow losses. There is also a description of fans and explain their characteristics depending on the pressure generated by airflow. The next part describes the design of the measuring chamber, electronics and control for fully automatic measurement of air quantities.

Development of Laser Welded Common Rail with Radial Connected Pressure Sensor (RPS)
Šantavý, Ivo ; Skrutek, Ivo (referee) ; Ramík, Pavel (advisor)
This dissertation deals with a development of a laser welded common rail with a radially attached RPS sensor of pressure. The new concept required by Bosch Diesel s.r.o. Jihlava should be more modifiable and it should be easily integrated with the engine compartment. In this dissertation I suggested a number of concepts that I further analysed, verified in appropriate software, developed, and finally narrowed the selection down to the most suitable solution, which is recommended and justified in the conclusion.

Pressure sensor made 3D structure
Hanus, Martin ; Pekárek, Jan (referee) ; Kosina, Petr (advisor)
This thesis deals with the points at issue of a 3D structure pressure sensor. The pressure sensor converts pressure into another physical quantity which is easier measure and which is processed subsequently. Usually ways of pressure sensing is for example capacitive, strain-gauge and optical. The 3D structures are constructed through the use of a LTCC technology, which can be laminated to create multi-layer structures, compared to standard high-temperature ceramics. Passive circuit components can be applied onto particular ceramic layers using either thin-layer or thick-layer technology. Practice part of thesis deals with several ways of construction a pressure sensor. First of all capacitive, strain-gauge and optical sensor and possible problems with construction individual sensors above all problems with lamination, cavity or burning

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.

Application of Thick Films in the Modern Electronics
Somer, Jakub ; Urban, František (referee) ; Szendiuch, Ivan (advisor)
Tato diplomová práce se zabývá technologií tlustých vrstev a jejím možným použitím pro nekonvenční aplikace. První část práce je rešeršní a zaměřuje se především na aplikace tlustovrstvé technologie v různých oblastech použití. V teoretické části práce je dále popsána technologie LTCC, včetně technologických postupů výroby. V praktické části jsou řešeny dvě aplikace v tlustovrstvé technologii. Jedná se návrh a výrobu vysokofrekvenčního filtru a optického senzoru tlaku technologií LTCC. V závěru práce jsou provedena měření a jsou zhodnoceny dosažené výsledky.

Digital signal of pressure senzors processing using CPLD
Zátura, Michal ; Fedra, Zbyněk (referee) ; Kováč, Michal (advisor)
The goal of this bachelor’s thesis is to design electronic part of the scanning system used to measure altitude. The electronic part is designed as module connected to the development platform XC2-XL. This module is realized like PCB. The principles of the signal processing of the signal from the pressure sensor MPXH6250, particular blocks of the designed module and principle of the barometrical altitude measuring are also described in this thesis. Thesis briefly informs about designing environment Xilinx ISE, VHDL language, the principle and the application of the pressure sensors, the structure of the programmable logic device CPLD and FPGA, the development platforms XC2-XL, the Xilinx Spartan-3 Starter Kit, the programmable logic devices CPLD Coolrunner-II XC2C256 and Spartan-3 XC3S200 FPGA used on the development platforms. The very important part is to design algorithm for processing the logarithm in the digital logic and it´s implementation in VHDL language.

Fuel Systems of SI-engines
Faiman, Jiří ; Drápal, Lubomír (referee) ; Dundálek, Radim (advisor)
The aim of this work is to create a list of fuel systems used in modern gasoline engines and describe the basic components of these systems. It will then be described the function of each of these components and modes of operation of the fuel system at different modes of engine operation. Finally, will be characterized by the selected engines with these systems.

Evaluation of pressure sensor placement into a floor of sewer line with supercritical slope
Štarhová, Marie ; Šafář,, Robert (referee) ; Žoužela, Michal (advisor)
This bachelor thesis investigates an installation of pressure sensor into sewage line bottom with supercritical slope. Original construction for installation of the sensor was unsatisfactory, therefore so called “bottom pocket” was designed. Using this design, the sensor is placed below sewer line bottom level. For investigation, several variants of sensor placement and its coverage were chosen. The aim of this thesis is to find the best sensor placement into the bottom pocket in combination with its coverage, so that figures reported by the sensor are the least possibly determined by Froudé criterium.
