Design of hot-swap of main accumulator of mobile robot
Kandera, Tomáš ; Rubeš, Ondřej (oponent) ; Krejsa, Jiří (vedoucí práce)
This thesis analyzes issues and available solutions of a hot-swap device, which allows the primary supply of mobile platform BREACH to be swapped without interrupting the operation of its components. The first part describes methods of redundancy and electrical phenomena during the hot-swap event. Second part describes creating schematics and PCB design of hot-swap controller, choice of backup power supply and design of its dedicated charger. Last part describes testing of the subsystems and complete system from multiple aspects.

Design of communication interface in WBAN systems
Kandera, Tomáš ; Najman, Jan (oponent) ; Krejsa, Jiří (vedoucí práce)
This thesis provides a technical realization of the WBAN device that supports concurrent operation of two wireless communication protocols. Recherche of available solutions is provided by rating multiple products, according to specified demands. The software part contains custom BLE service design, Timeslot API setup, and configuration of peripherals commonly used in WBAN devices. Printed circuit boards for the multiprotocol device prototype and its dedicated controller are made, including custom antenna, power supply management solution, and nRF52810 SoC circuitry. Prototypes testing is summarized in the last chapter with signal attenuation experiment.
