We are pleased to inform that two inventions presented by scientists from the AGH University of Science and Technology were awarded medals at the 43rd International Exhibition of Inventions of Geneva. This biggest event in Europe exclusively devoted to inventions was held in Geneva on 15-19 April, 2015.

Gold medal with distinction: Separation drain street inlet

Inventors: professor Elena Neverova-Dziopak of the AGH UST Faculty of Mining Surveying and Environmental Engineering, and professor Daniel Słyś of the Rzeszow University of Technology


The separation drain street inlet enables an effective separation of rain sewage into the sewage of high level of contamination, which requires further purification, and the sewage of low level of contamination, which may be drained directly into the rivers. The device allows to separate sewage directly at catch basin grates on the streets of towns and cities. The inlet also enables a simultaneous drainage of less contaminated rain sewage into the ground, which is beneficial from point of view of the environmental protection, as well as the maintenance cost of sewerage systems. The separation of rain sewage into less and more contaminated streams is based on the differences in hydrodynamic properties between the first and the subsequent waves of rain and their kinetic energy. This inexpensive and environmentally friendly solution enables the hydraulic relief of sewerage systems and waste-water treatment plants, as well as the infiltration of clean sewage into the soil, which helps to supply underground waters.

Silver medal: Precise and ultrafast integrated circuit for new generation pixel digital X-ray cameras

Inventors: professor Paweł Gryboś, professor Robert Szczygieł, Piotr Maj, DSc, and Piotr Kmon, DSc, of the Faculty of Electrical Engineering, Automatics, Computer Science and Biomedical Engineering


The invention is an ultrafast integrated circuit composed of ca. 50 million transistors, designed for modern X-ray cameras. The presented chip combined with a pixel silicon detector allows to take precise X-ray photographs with the speed of several dozen frames per second. For example, the parameters of the integrated circuit make it possible to observe dynamic physical processes, to obtain quickly a localisation of micro-defects in steel elements and constructions, as well as to conduct tests on delicate biological objects (example – photo of a daisy taken with the use of X-radiation). The project is carried out within the framework of a research grant of the National Centre for Research and Development no. PBS1/A3/12/2012.


This year’s exhibition “Geneva Inventions” was participated by 752 exhibitors from 48 countries, who presented in total over 1,000 innovative solutions. Within the five days, the exhibition was visited by over 60 thousand people.


Polish inventors, who represented scientific research units and industry, presented over 40 solutions at the exhibition. Poland’s medal account looks as follows: 13 gold medals, including as many as 5 gold medals with distinctions, 22 silver medals, and 4 bronze medals. It is worth noting that the number of presented solutions gives Poland the third place among all the countries which were present at the exhibition (just behind China and Thailand).


Alongside the exhibition, the Association of Polish Inventors and Rationalizers organised a “Polish Day”. An honorary guest of the event was Dr Alicja Adamczak, President of the Polish Patent Office, who, after visiting the Polish stand, took part in the ceremony of presenting distinctions and medals awarded by the international associations of inventors to the Polish team.
