This paper presents the architecture of a low cost embedded platform for Web-based monitoring and control of a smart home. The platform consists of a distributed sensing and control network, devices for access control and a residential gateway with touch-screen display offering an easy to use interface to the user as well as providing remote, Web based access. The key issues related to the design of the proposed platform were addressed: the problem of security, the robustness of the distributed control network to faults and a low cost hardware implementation.

This paper introduces a combined analytical and numerical approach in order to study the suitability of a coil array for contactless transfer of the energy needed for the charging of batteries in active transponders. The way in which the geometry of the coil system influences the efficiency of the transfer is analyzed based on flux computation. An array of planar, circularly shaped primary coils is proposed as a solution to transmit the energy to a secondary coil, contained in the active tag, for situations of random placement of the active tag above the coil array.

Kombinuotas analitinis ir skaitmeninis ričių masyvų bekontakčiam baterijų krovimui aktyviniuose transponderiuose tyrimo metodas // Elektronika ir elektrotechnika.-Kaunas: Technologija, 2012.-Nr. 7(123).-P. 37-42. Pristatomas kombinuotas analitinis ir skaitmeninis metodas, skirtas ričių masyvų tinkamumui bekontakčiam baterijų krovimui aktyviuosiuose transponderiuose tirti. Analizuojama, kaip ričių sistema veikia energijos perdavimo efektyvumą, skaičiuojant sroves. Planarinių apskritimo formos pirminių ričių masyvas pasiūlytas kaip energijos perdavimo į antrinę ritę, esančią priėmimo pusėje, sprendimas, atsižvelgiant į atsitiktinę ričių tarpusavio padėtį.

Abstract-The paper aims to analyze the time and frequency domains of EMG signals coming from healthy patients and from patients with muscular disorders (muscular myopathy and neuropathy). The study of these signals can reveal some features in time domain or in frequency domain, that can serve as a basis for diagnosis.

The paper presents different ways of transmitting biomedical signals, depending on the transmission's range. Thus, the new wireless technologies, combined with the data transmission within a Local Area Network (LAN) or the internet, will contribute to a better health-care system developing.
