Data collection from sensor units
Frkal, Pavel ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
This thesis deals with data collection from sensor units connected via 6LoWPAN standard (IEEE 802.15.4 standard), which uses simplified IPv6 protocol on the network layer. Featuring optimization makes this solution suitable for use in systems powered with chemical power supplies with a very low current consumption of both the sensor units and the control units. The thesis focuses on collecting data from sensor units that communicate on a star topology basis but it's also discussed possible usage of general topology, the end-station in such case works as active repeater and thus extend sensor network coverage without need of additional devices for wireless frames repeating or forwarding. It evaluates the realization of sensor networks created by both the actual data collection as well as specific technical parameters of used sensor boards. The practical part contains a specific application for gathering data from sensors present on the units and storing them in a relational database MySQL.

Temperature regulator
Fireš, Martin ; Richter, Miloslav (referee) ; Macho, Tomáš (advisor)
This work deals with design and construction of the temperature regulator with a resistive load as primarily. Each structural element is described by a theoretical part which is needed for further understanding and practical solution the thesis heads for. The current output for half-wave modulation is solved in PSD control loop using temperature measurement by DS18B20. Rotary encoder, character display or PC visualization are used to controlling and displaying.

Upgrade of extruder head for 3D bioprinting of thermolabile hydrogels
Kedroň, Kryštof ; Harabiš, Vratislav (referee) ; Jaroš, Josef (advisor)
3D bioprinting is a perspective method of tissue engineering, capable of creating tissue structures with physiological function and spatial arrangement. The thesis deals with the use of this method for printing thermolabile hydrogels. The main goal of the thesis is to extend the print head for 3D printing of thermolabile hydrogels. The theoretical part is devoted to the description of 3D bioprinting, especially the important properties that each material must meet to be able to print, there is also a review of used hydrogels in bioprinting, focusing on thermolabile, print modalities, the possibility of cooling the printhead and a description of the ideal equipment for printing of thermolabile hydrogels. The practical part deals with the design and realization of the print head for 3D printing of thermolabile hydrogels, in the last part the achieved results are evaluated and discussed.

Control unit for an industrial convection oven
Augustin, Stanislav ; Dušek, Martin (referee) ; Kubíček, Michal (advisor)
The contents of this semestral thesis is to explore ways to design of controll unit for convection oven for prototype transformers production for welding technology and design a scheme of the unit. The controll unit must be able to regulate the ambient temperature inside the oven using a power management of heating elements (for example heating rail) inside the oven.
