The natural gas stations typically comprise overground facilities for filtering, pressure reduction, flow metering and odorizing. The facilities and the interconnecting pipelines are subject to risk of damages due to material failures or external factors. The failure detection algorithm presented in the paper is based on two physical phenomena concerning the temperature of piping. The first one is bound to the process of natural gas expansion to the atmosphere leading to a rapid decrease of the gas temperature, usually below the ambient temperature. Therefore, the flux of gas absorbs heat from the pipe walls implying a local drop of the surface temperature. The second phenomenon is related to the change of the flow pattern in the station, since leakages typically induce high discharge flow rates. The new flow pattern affects the thermal effect exerted by the gas flux on the pipe walls, hence significant variations from previous values as well as from the ambient conditions may be registered in short-time intervals. The algorithm implements integrity test procedures based on both thermal mechanisms, as well as initializing procedures for image normalization and identification of relevant pipeline sections.

There are numerous facilities that are endangered of an terrorist or an fanatic individual attack. Commercially used weapon detection gates are very expensive and sometimes impossible to install into already existing security infrastructures. Here we present a miniature prototype device for concealed weapon detection using two cameras: IR and visual. The prototype consists of two printed circuit boards (PCB). First PCB is responsible for analog to digital and digital to analog conversions of the video stream. The second board is the main processing unit realizing the presented fast image fusion algorithm. The relative size of the prototype can be assumed as a miniature in comparison to the current used solutions. Such miniature device could be mounted under the ceiling or inside 3 DOF gimbals for wider view angle. Presented device can be considered as an alternative to already existing man-sized gates traditionally used for CWD.

The entire system, hardware and software are scalable and compliant with the Wireless Body Area Network model. The wearable system modules can work independently and continuously indoor and outdoor. Each of the tracking and controlled subjects is wearing a Body Acquisition System (BAS). BAS is a human acquisition system for monitoring human motion and multiple physiological signals. It is built into a wearable unobtrusive smart clothing and enables to create wireless sensor network using WIFI for external communication, local hub for local data acquisition, processing and transfer. The central hub for global data processing and data exchange has been developed as Cloud Based Human Multimodal Database (CBHMD). A software application, Multimodal Data Environment (MMDE) has been built to visualize and control the acquisition and monitoring process. MMDE allows domain experts such as physicians, physiotherapists, film producers, to work with connected BASs control and react in real time. MMDE enables remote communication, data acquisition directly from BASs, diagnostics, management and maintenance of medical devices in BASs, as well as data processing using customized processes and algorithms.
