Visual inspection becomes very important part of mechatronic and industry applications. The methods which replace human eye and human factor increase speed and reliability of many processes. Virtual instrumentation (LabVIEW from National Instruments e.g.) is very good environment for developing visual inspection tools integrating all basic elements: imaging sensors, I/O hardware and algorithms [1]. Paper focuses on possibilities of designing automated visual inspection link based on LabVIEW for searching and counting of selected parts of products. Algorithms such as Pattern and Geometric Matching, Color Location or Hough Transformation are key elements of all software solutions. Designed visual systems also serves like client communicating with superior system (server) via TCP IP enabling remote control
The main paper deals with the analysis of the methods of signal processing and events recognition in the audio signal and the implementation of the selected method in real use. Recognized events are gunshots mixed with a background sound such as traffic noise, human voice, animal sounds and other forms of environmental sounds. The proposed algorithm adapted for explosion detection can be used as part of a security system for monitoring depots or places dedicated to storing dangerous materials. For events classification and class recognition, the freely available machine learning frameworks TensorFlow and Keras are used.

There is no direct evidence for the exact cilia-inhibitory effects of opioids, which are generally used to achieve general anesthesia in combination with other anesthetic drugs. These are the reasons, why we analysed direct concentration-dependent or systemic effects of anesthetics (propofol, sufentanil, and midazolam) at a recommended doses administered individually or simultaneously on the tracheal ciliary beat frequency (CBF) in in vitro experimental conditions. Brush biopsy technique was used to remove the tracheal epithelia of guinea pigs for microscopy evaluation of ciliary beating monitored by high-speed video camera and analysed by Ciliary Analysis software. The tracheal CBF was significantly lower in the presence of sufentanil (10-8 mol/L) than in the control group; similarly for midazolam-sufentanil (10-8 - 10-5 mol/L), as well as for midazolam-propofol (10-5 and 10-3 mol/L) combinations. The fact that concurrent administration of benzodiazepine significantly increased the risk of sufentanil-induced cilia-inhibition was pharmacologically confirmed using GABAA receptor antagonist, bicuculline methiodide. The benefit of propofol on the potent cilia-inhibitory effect achieved by benzodiazepine-opioid combination was non-significant. We highlight the pharmacodynamics interaction between anesthetic drugs mediated via GABAA receptor with negative impact on the CBF in a respiratory epithelium under experimental condition rather than the effect of individual anesthetic.
