Design of indirect sensing of gas valve throttle position
Burian, Jaroslav ; Jankovský, Jaroslav (referee) ; Otáhal, Alexandr (advisor)
This thesis deals with the design of a circuit for measuring the throttle position of the PX52 valve from Resideo. The theoretical part discusses the methods whose principle can be used to determine the position of the throttle valve controlled by a stepper motor. Subsequently, the communication protocols that can be chosen between in the design are described. Methods for measuring the mutual properties of the coils were also described. In the practical part, a PCB was created to verify both methods. Furthermore, a program for testing both methods is described in the paper. These methods are compared with each other for different coil variants. Finally, the method is selected and the program is modified for the measurements.
Design of Power Supply for Aircraft Model
Šrámek, Martin ; Huzlík, Rostislav (referee) ; Hadaš, Zdeněk (advisor)
Diplomová práca, ktorú držíte v rukách, sa zaoberá návrhom elektrického generátoru pre modely lietadiel na diaľkové ovládanie poháňané spaľovacím motorom. Takýmto modelom je dodávaná energia pomocou batérií, ktoré sa musia po vybití vymieňať. Motiváciou tejto práce bolo potlačiť potrebu pristávania za účelom dobíjania batériových paketov. Práca vyvíja niekoľko analýz a simulačných modelov pre riešenie tohto problému.
Evaluation of broadband couplers for noise injection into powerlines.
Malček, Ladislav ; Musil, Petr ; Mlýnek, Petr
This paper deals with the problem of coupling noise into the transmission power line. The main goal is development of device which can effectively inject noise into transmission lines. This device will be used for testing industrial or commercial-used BPL (Broadband Powerline) modems and their ability to communicate under certain conditions. In the first part, there is an overview of coupler types. Next, the appropriate type was chosen according to required qualities. PCB (Printed Circuit Board) design of final device was developed on the principle of capacitive coupler. In the end, final PCB design was tested with several combinations of magnetic coils and capacitors.
Compact vacuum assembly for trapping and laser cooling of 27Al+ and 40Ca+ ions
Grim, Jakub ; Vlček, Ivan ; Jedlička, Petr ; Pham, Minh Tuan ; Číp, Ondřej
We present the design of a compact vacuum chamber for trapping and laser cooling of 27Al+ a 40Ca+ ions. The vacuum chamber has been designed to a compact size to achieve good optical access to the trapped ions and ultra-high vacuum in the chamber. In combination with the Helmholtz coils, saddle coils, and magnetic shielding is achieved a homogenous magnetic field in the ion trapping area. The presented apparatus will enable quantum experiments with single ions and also Coulomb crystals.

Electromagnetic Flowmeter
Kulenda, Vít ; Uher, Miroslav (referee) ; Beneš, Petr (advisor)
Bachelor thesis describe elementary principle of electromagnetic flowmeter. It contain information about their attributes, construction, montage and using. Problem of this flowmeter are explained, which can appear during their using and building. Own constrution of electromagnetic flowmeter are part of thesis, where procedure of desing electronic circuits are decribed. In the end reports and graphs are published. Because this flowmeter are intended for laboratory, construction of vessels are contained too.
