Design digital optical output
Kubáč, Stanislav ; Beneš, Petr (referee) ; Klusáček, Stanislav (advisor)
This work descibes general principles of measuring the alternating current and voltage using conventional and unconventional sensors.This work shows specific parmeters conected with principles of the measurement, advantages and disadvantages of individual measuring procedures, types of output signals, precisions, limitations, ways of power and so on. Part of the work is to find optimal measurement procedure, which can be aplicated to practical measuring of alternating currents and voltage. Main part of the work concerns the realisation of optimal method of measuring alternating current.

Strain Gage amplifier
Kneblík, Adam ; Havránek, Zdeněk (referee) ; Beneš, Petr (advisor)
The thesis deals about method of gain signals from strain gauge bridges. There are mentioned some signal conditioning methods for bridges amplifiers and charactered their properties. In the next part of this thesis are calculated the amplifier errors for various temperature. There are projected individual variants of strain gage amplifiers (instrumentation amplifier AD524, isolation amplifier, switched capacitor based instrumentation amplifier), their properties are compared with strain gage amplifier Vishay P-3500.

Power harvesting sensors
Arnošt, Karel ; Klusáček, Stanislav (referee) ; Beneš, Petr (advisor)
The thesis deals with power harvesting sensors as a source of energy. As the power requirements for microelectronics decreases the environmental energy sources become more perspective. In a few last years batteries reach a higher capacity but there is still problem with their replacement. Power harvesting sensors appears as a good solution for powering microelectronics.

Eddy current sensors
Gregor, Lukáš ; Fidler, Petr (referee) ; Beneš, Petr (advisor)
This master’s thesis discourses the problematics of eddy current sensors of transformer type dedicated for measuring non-contact distances of unferomagnetic and feromagnetic objects. This thesis contains the design, realization and finding of the optimal values for the sensor usage. The sensor properties are measured and certified by empirical calculations and simulations in the Comsol Multiphysics programme.

Workplace of flow and pressure measurement
Brabenec, Jiří ; Beneš, Petr (referee) ; Bejček, Ludvík (advisor)
The thesis deals with formation of a workplace for preparation gaseous mixtures and their future usage. The main goal of the thesis is testing of new materials which have suitable usage as catalysts. Gaseous mixture is prepared by calorimetric mass flow meters with control valve and multiposition microelectric valve actuators. The next part describes measuring of pressure and temperature and controlling of furnace temperature. The thesis deals with specifications of all devices, their circuitry, communication and program controlling. All devices are controlled by computer with program which is programmed in LabVIEW.

Signal Analysis
Vávra, Pavel ; Keprt, Jiří (referee) ; Beneš, Petr (advisor)
This thesis deals with problem of analysis signal acquiring measurement of uniformity motion harmonic drive and planetary gearboxes. In introduction part are explain some features of FFT and concept of cepstrum. Further is present overview of most often measured parameters of these gearboxes and needed formulas, which express connections among particular mechanical parts of gearboxes. The next part deals with description of SW program unit generated in LabView environment, which is output product of work and makes analysis on measured courses.

Inclinometers and Gyroscopes
Hývnarová, Irena ; Beneš, Petr (referee) ; Havránek, Zdeněk (advisor)
This study deals with tilt sensors. Besides others methods, accelerometers and gyroscopes are also convenient to solve this problem. Tilt sensors which are described in this thesis are working with capacitive, piezoresistive and thermal method. Capacitive accelerometers from producer Analog Devices, STmicro and Freescale, piezoresistive accelerometers from producer Panasonic Matsushita and gyroscope ADXRS300 are tested by practical measurement. Parameters of these accelerometers are found and they are compared with parameters from producer. Measurement reliability in this study is analysed as well. This thesis is divided in chapters theoretically describing principles of particular accelerometers and the chapters containing measured data evaluation.

The family house with place of busines
Guzdek, Michael ; Berousková, Dana (referee) ; Beneš, Petr (advisor)
Bachelor’s thesis deals with the preparation of a new detached house with a place of business at a level of the documentation for the structure realization. The building is partly basement with two above-ground floor and a flat roof. The building is situated on steep terrain of the village Krásné Pole. The work puts emphasis on layout including security of the construction in terms of statics, architecture, energy savings and safety at utilizing the structure.
