The following work deals with a design of power supply testbench with design of their replaceable modules and circuits for their measurement. The final product should be used for faster design and tuning of switching power supplies. In this essay, there is detailed description of switching power supplies, analysis of support circuits and calculations for design. Based on theoretical background and selected parameters, a connection concept will be created. This concept will be validated by a device that will consist of main board, changeable modules and measurement circuits.

The content of the master’s thesis is the elaboration of a real business plan, which deals with the creation of a digital space for the professional self-realization of customer segments. The theoretical part describes the specification and verification of the initial idea of the plan using the Lean Canvas tool, qualitative research among the first customers and other analytical methods to define key factors from the general and market environment and internal sources. The analytical part focuses on the application and results of selected analytical-research methods, including evaluation for the subsequent selection of a suitable market entry strategy. The proposition part contains the final business and market strategy and business model, which is developed into individual parts of the business plan.

This diploma thesis is dedicated to one of the problems in wireless sensor networks – over the air upgrade (OTAU) of nodes. The requirements for upgrade and possible ways how to transfer new firmware image to nodes are stated in the first chapter. The second chapter is focused on solving the problem of firmware dissemination to whole network based on analysis of known protocols. The practical part of this thesis deals with OTAU design and implementation in Lightweight Mesh software stack from Atmel. Proposed system was tested on deRFnode platform with plugged in deRFmega128 module. The upgrade process of designed system is evaluated on test network in last part. Practical test results are compared with OTAU solution for BitCloud.
