Virtual factory for PCB and thick-film circuits fabrication

The contribution describes practical implementation of virtual processing approach in education of electrotechnology, aimed to printed circuit boards (PCB) and thick-film circuits fabrication as a part of the virtual electrotechnology factory building. Appropriate tools are described for particular components development. The current knowledge in the field of web publishing and animation technology was used during development. The study texts supported by animations and video materials of technological procedures are the opus locatum at virtual factory development.

Virtual electrotechnologic factory as a tool for e-learning

This paper represent an approach of applying the graphical visualization methods to the educational process. The Virtual electrotechnologic factory is created based on theory and contains the theory itself. The technology utilized during the process of the development was the Flash multimedia platform. This allowed us to visualize all the theoretical processes, logically connect them and link them with other multimedia content such as animations, video, still images or audio. Moreover factory was created in two language versions and possibility of offline and online usage is available. Virtually all the content is loaded into the factory from external folders and thus allows easy editing without the need to access the Flash source files. This method of visualizing educational material may be used for other areas of education.

Animated components in the scope of the electronic technologies education

The contribution deals with possibilities and practical utilization of animated components in educational process with the scope of technologies used in microelectronic industry. The effort in this area is the part of evolvement of multimedia support in education process at the Department of Technologies in Electronics of Technical University of Košice. With utilization of multimedia components were created number of study modules for electronic educational courses in the area of materials, technologies and sensors used in electronics industry.

E-learning system and virtual laboratory for the study of electronic technologies

The paper describes the e-learning system and virtual laboratory that are intended for implementation into electrotechnology-oriented study programs. It is a short description of the main functions of the systems as well as the technologies used for the implementation.

Low-cost assistive device for hand gesture recognition using sEMG

In this paper a low-cost solution for surface EMG (sEMG) signal retrieval is presented. The principal goal is to enable reading the temporal parameters of muscles activity by a computer device, with its further processing. Paper integrates design and deployment of surface electrodes and amplifier following the prior researches. Bearing in mind the goal of creating low-cost solution, the Arduino micro-controller was utilized for analog-to-digital conversion and communication. The software part of the system employs support vector machine (SVM) to classify the EMG signal, as acquired from sensors. Accuracy of the proposed solution achieves over 90 percent for six hand movements. Proposed solution is to be tested as an assistive device for several cases, involving people with motor disabilities and amputees.

Possibilities of motor oil continuous diagnostics

Connecting to motor aggregate reliability and operational life it is very important to reliably observe the oil change interval. Determination of critical parameters of motor oil is important for correct statement of its condition in engine. By implementation of sensor system which directly acquires several parameters simultaneously, it is possible to achieve the better sight onto degradation process of motor oil. Some most relevant, mainly electric parameters were investigated at samples of standard semi-synthetic motor oil and discussed with inscribed the subsequent interest.

Heat dissipation based on LTCC-HTCC heterostructure

Articles deals with technology of realization of LTCC-HTCC heterostructure based on different thermal conductivity of substrates as well as with fabrication process of inner channels on the interface of heterostructure. In the practical part the results of measurements on realized samples for the purpose of use in field of heat dissipation from electronic microstructures are presented.

The computer animation in education

This paper presents a new approach to use of the animations as a tool for education. Our approach is focused on the methodology of designing the animation rather than on the study whether it is or is not beneficial in the educational process. We will introduce the animation as a tool, present commonly used tools for development and then introduce a basic technique for developing an animation. Education is the most powerful mean to improve the understanding and the ability to perceive the world, therefore its resources should be used wisely.

The design concept of system integration based on heterostructure

This study shows technological realization of heterostructure LTCC structure - HTCC substrate. Heterostructure realization results are analyzed regarding the application of LTCC ceramics and HTCC substrates where possible solution is local heat dissipation from power elements. Technological solution has been applied during the 3D integrations of mobile mini-machine control electronics in a System on Module (SoM) assembly.

System for control of limb straining in rehabilitation process

The paper deals with construction of rehabilitation insole for medical use. The purpose of its application is in time indication of rehabilitated leg overloading. The patient has to follow the limited burden of the injured leg at a certain stage of the rehabilitation process. As recommended by doctor, rehabilitation specialist defines partial load of limb from 10 kg to full load with adjustable insole support. Rehabilitation insole monitors loading of the leg and provide the feedback to the patient. The system is fully integrated and with the exception of charging it needs no special approach during application by the patient.
