This paper presents a universal stand to diagnose air gear models made in the process of Rapid Prototyping (RP) at the production stage. The stand is designed in an open system, powered by a three-phase electric motor with a power of 0.75 kW, whose speed is controlled by a single-phase inverter. The stand is equipped with two measuring shafts, connected directly to a recorder RMC that allow you to read values torque and rpm in real time. Between this measuring shafts installed a gear reducer to allow the exchange of tested pair of gears. Powder brake with variable speed control is installed on the output as a load. Responsible for data acquisition software is copyright RMC-M-Monitor, which allows you to preview the results of measurements and print them in a report. Trials conducted on the universal test stand for air gears demonstrators give reproducible, stable work parameters and thus enable to obtain uninterrupted, accurate measurements.

In this study the methodology of balancing water needs in a crisis situation was presented. The example was done for city of Rzeszow. The municipal infrastructure: water supply system, sewage system, gas network, heating and energy systems was shortly characterized. The research undertaken in this study was related to Systemic Crisis Management and protection of the inhabitants of the city. The balance of emergency water supply Rzeszow in drinking water for the 29 neighborhoods of the city was shown.

The properties of energy conditioning electrical circuits that are developed for powering additional functional blocks of autonomous RFID transponders working in the HF band have been analyzed and presented in the paper. The concept of autonomy is realized by implementing extra functions in the typical transponder. First of all, the autonomous system should harvest energy, e.g. from the electromagnetic field of read/write devices but also the possibility of gathering information about environment should be available, e.g. by measuring different kind of physical quantities. In such an electrical device, the crucial problem consists in energy conditioning because the output voltage-current characteristic of an front-end (antenna with matching and harvesting circuit) as well as the total and instantaneous power load generated by internal circuits are strongly dependent on a realized function but also on energy and communication conditions in the RFID interface. The properly designed solution should improve harvesting efficiency, current leakage of supply storage, matching between antenna and input circuits, in order to save energy and increase operating time in such a battery-free system. The authors present methods how to increase the autonomous operation time even at advanced measuring algorithms. The measuring system with wide spectrum of sensors dedicated for different quantities (physical, chemical, etc.) has also been presented. The results of model calculations and experimental verifications have been also discussed on the basis of investigations conducted in the unique laboratory stand of object navigation systems. © 2014 SPIE.
