It became a standard to collect data and create databases of human gait characteristics. One of the reasons is to derive standard deviations to be able compare patients' data. The most laboratories create their own databases to ensure objectivity in evaluation of pathological gait cases. Acquired normative data of lower limb anatomical joint angles were compared with normative data of three different world laboratories in this study. Methods of statistical characteristics testing were used for their comparison. The results of these tests showed considerable differences at the significance level alpha=0.05. It is evident, that there is still no standard database to compare gait data acquired in different laboratories. The trends are to establish standard roles for data acquisition to ensure objective assessment of patients' gait.</div><br />

Nowadays, the deployment of low-cost platforms, such as Raspberry Pi is applied not only in educational or hobby projects, but it finds application also in industry or various commercial products. Therefore, it is crucial to explore the possibilities of using such low-cost systems. Target setting. The research aimed to create a "low-cost" photo booth that would be comparable or better in parameters to commercial solutions, but at a much lower cost. Actual scientific researches and issues analysis. When designing the system and preparing this paper, we considered both current sources – publications and papers dealing with the current state of development of the photo booth as well as existing solutions, which are available on the market. Uninvestigated parts of general matters defining. The created photo booth solution currently neither have printing applied, nor send the resulting photos to email or cloud automatically. It will be implemented in the next stage of development. The research objective. The purpose of this article is to explain how we can create original photo booth using Raspberry Pi platform. The statement of basic materials. We used single-board low-cost microcomputer Raspberry Pi, and in combination with a camera, we made a photo booth. For this system, we created a control program in the Python environment, which is one of the most widespread programming languages and finds application in various areas. Conclusions. Using the Raspberry Pi and the camera, we created a fully functional photo booth qualitatively comparable to commercially available products at a much lower price.

To solve this, we provide a different view of the interconnection between individual devices (positioner, robot, etc.) controlled by third-party methods (Siemens products). Also, to obtain the necessary effectiveness, we tested and verified selected accuracy parameters for the participating device component (positioner). The proposed work tries to fulfill expectations for a precise welding technology (to ensure simultaneous movements of both the industrial robotic arm and positioner) to achieve higher quality and productivity. However, the components are from different manufacturers.

These physical characteristics of patients are followed by sensors and the output information is broadcasted via Zigbee to PC for further processing. The tested e-health system is based on Arduino e-health kitwith Zigbee for transmitting information and a PC with Arduino and Zigbee for receiving data. Bluetooth is a well-known conventional wireless data transfer protocol, but it´s not much encouraged for long duration applications because of power consumption limitations, so Zigbee offers a better solution for such cases. Basic tasks of the system are to measure main health functions as heart rate, body temperature and body position. The tested system enables quick access to parameters of monitored biosignals, therefore identification of health risks and intervention can be provided in real time [1].

Four young sportsmen participated in the initial study. They have performed standing long jump in two measuring conditions: with and without arms swinging. Motion was captured using a 3D opto-electronic camera system SMART (BTS) and selected kinematic data were evaluated using software packages and data processing: trajectory of body centre of gravity (COG), velocity of COG, maximal vertical distance of COG, takeoff angle together with momentum of upper extremities were analyzed. The data were statistically evaluated using descriptive statistics and analysis of variance. Statistical significance of the kinematic data and jump length were analyzed using the Kruskal-Wallis test and post-hoc test (p<0.05) in Statistics toolbox of Matlab program. Statistically significant differences were assessed within intraindividual and intraclass comparison of data.

Particularly, if there is a cobot (collaborative robot) as a main part of workplace. This article concerns the chosen aspects for cobot implementation into the automated workplaces with emphasis to the safety as general and important factor. The article structure describes main techniques for safe operation in order to optimization of workplaces as an industry 4.0 concept. Their implementation is based on a proper understanding of on-site activities in the form of available information about material flow, number of produced components, quality or specific measured values from different sensor types. The information contributes to correct automated innovation implemented as a specified type of cobot with regard to safety as a main factor. The strict separation of robots, humans or other peripheral equipment is currently being phased out with a sensitive integration into group building of automated workplaces. For these reasons, discussions on safety categorization, standards and options for safe operation in automated workplaces are still ongoing.

This article focuses on the analysis and evaluation of existing material flow at the manufacturing operation. The assessment is based on comparing the total distance traveled during the transport of material for certain time consumption. And due to financial indicators, the costs necessary for the operation of the production workplace are monitored. In the efficient operation of the production system, efforts are made to minimize traffic routes, thereby reducing transport costs as well as the need for means of transport.
