This article presents our experience in integrating solar harvester systems into engineering training. The increased capacities of supercapacitors, as well as their advantages over ordinary batteries, together with harvester systems, make them extremely sought after and used by researchers and engineers to implement various projects. Following this trend, we have integrated into the students' practical classes laboratory exercises in the engineering disciplines “Microcontroller Design” and “Microprocessor Technology”, software and hardware methods for reducing the consumption of wireless sensor nodes and using solar energy harvesters as energy sources for sensor nodes. The article focuses on experimental studies of different harvesters - LTC 3588 and BQ25570, collecting energy from different photovoltaic panels. Students can design and implement autonomous wireless sensor nodes to be powered by solar energy harvesters. In this way, they acquire skills and knowledge to implement low-energy wireless sensor nodes without harmful chemical batteries. A good knowledge of solar harvester systems leads to an increase in the quality of engineering education.

This paper presents comprehensive research on the influence of the parameters and characteristics of wearable antennas on off-body channels in Wireless Body Area Networks (WBANs) in an indoor environment at 2.41 GHz in a line-of-side scenario. From the results, we can conclude that the surface, radiation efficiency, and radiation pattern of the wearable antenna play a vital role in the definition of the off-body channel characteristics.

The article discusses some aspects of teaching mechatronic systems based on a physical model of an elevator. After introducing the major building blocks of a typical mechatronic system, state-of-the-art control approaches are discussed in the paper. They include the software-centric jump table, the hardware-oriented finite state machines, and the use of the modern meta-operating system for robots ROS. The described physical laboratory mock-up and the suggested control methods provide a solid platform for teaching mechatronics in a real or remote environment without loss of realism.

Working in the mining industry is associated with a serious risk to the health of workers. For this reason, increasing the level of automation and security is a topical issue. The article proposes a project for the construction of a system for monitoring the atmosphere in an open pit mine using wireless technologies. The considered platform offers a universal, flexible and affordable device, allowing the collection and analysis of a large amount of data in real time. Experiments have been conducted with sensors of microelectromechanical type, which appear to be a good candidate to replace the more expensive electrochemical ones.

This paper11This publication has emanated from research conducted with the financial support of the Bulgarian National Science Fund (BNSF) under the Grant No. KP-06-IP-CHINA/I (K∏-06- HIT - KHT AN/1). describes a generic architecture for the creation of universal interpersonal communication applications (UICAs) capable of selecting the ‘best’ service for communication with particular person(s), depending on the current context, based on the calculated service ratings considering different evaluation criteria. A suitable service categorization, serving the UICAs, is proposed. The relevance of the UICA approach to a user-centric realization of the Always Best Connected and best Served (ABC&S) communication paradigm is highlighted.
