Unit for wireless transmission of electrical energy
 Jelínek, Aleš ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
The aim of this work is to prove the practical applicability of the concept of contactless energy transfer using induction coils. The first part deals with the mathematical model and theoretical proof of the concept being able to work in practice and describes the process of detecting resonance of receiver circuit on transmitter side. Next chapter describes hardware solution of the experimental prototype. The last part contains measurement results of a coupling coefficient of coils and discusses performance and notable features of the prototype.

IR thermometer
 Kobza, David ; Čech, Petr (referee) ; Rozman, Jiří (advisor)
This master's thesis deals with the issue of temperature measuring with the use of contactless thermometer. The thesis examines the physical findings, methods and detectors for contactless temperature measurement. Is then selected a suitable detector, measuring methods and assembled a block diagram of the IR thermometer. The main section is a specific system design. This includes circuit solution, including printed circuit board design and simulation of the functional parts.

Measurement of conductivity of liquids
 Mašláň, Stanislav ; Havránek, Zdeněk (referee) ; Beneš, Petr (advisor)
The first part of thesis is theoretical and it is the introduction into conductometry. It defines the essential terms of this field as well as contact and contactless methods of measurement of fluid conductivity and also the influential parasitic phenomena and possibilities of their elimination. The second part is dealing with design of the contactless transformer conductivity probe. The characteristics of designed probe are verified in the practical part of the thesis. The final part of the thesis is dealing with measurement according to the defined points in the assignment. The characteristics of several contact probes are verified and also the characteristic of the contactless transformer probe, which was implemented according to the design from the second part. Outcomes of these measurements establish the suitable power supply frequencies and currents for all these probes.
