Two patents were granted in the field of resonance measurements representing a significant achievement in the exacting measurements of small impedance changes. Both patents were implemented in the industry and a multi-purpose hybrid circuit designed for resonance measurements was developed. A contribution was made to the international scientific encyclopeadia of electrical and electronics engineering, which covers the core knowledge and the latest developments in the field and represents an important contribution to the development of science. Moreover, an active role has been played in the creation of the new standards. Also, a genetic algorithm for the computer measurement system optimization was constructed. Also developed were technologies for differential GPS (DGPS) to be used in road vehicles and sea vessels, for the computer-based measurement of materials accumulating electrical charge and for the Internet-based measurement via pocket PC (pocket PC as a modern instrument) and notebook PC, then the method for the measurement of the porosity of volcanic rock based on quartz crystals, the methodology for the measurement simulator designed for the research of the measurement uncertainty (which was also implemented in the educational programs), algorithms for controlling compressed image quality based on fuzzy computing and neuron networks and advanced coding for image compression based on fuzzy logic. The research work was particularly focused on Web-based remote measurements and virtual instrumentation. Useful results were also achieved in the field of Bluetooth technology and GPRS-based measurement data transfer. In the measurement of quantities, new procedures for the measuring and calibration of 3D position, velocity, height and accelerations of the moving object using satellite signals were developed. Further results were achieved in the field of influence quantities. They involved improved temperature stabilization of the parallel measuring structure and two developed measuring probe prototypes operating at the frequency of 48 MHz (improved measuring accuracy and stability as well as general applicability), development of a special model for the optimization of the measuring uncertainty in the steady state (whose advantage is general applicability and comparativeness) and EMI-filter simulation model as well as the development of some actual filters designed for the reduction of disturbances caused by digital switching circuits (the modelling of the filter in question enables the determination of its elements on a case-to-case basis). Also developed was a two-way data transfer in the existing cable TV network and its optimisation with various algorithms for diverse data types, special microcomputer modules with signal processors for predictive regulation systems based on non-parametric models. It is furthermore worth mentioning the development of the intelligent controlling methods with theoretical emphasis on the neuron networks. Also successful was the research in the field of multimedia systems, where the experimental foundations for the distance learning covering the contents and techniques of high-speed data transfer were developed. In the field of image setting the upgraded procedure for the pattern recognition based on advanced polynomials was deployed. In addition to the patents mentioned, a number of articles were published in scientific journals with impact factor.
