Towards the next generation of intelligent building: An assessment study of current automation and future IoT based systems with a proposal for transitional design

The intelligent building, a major smart city research and development domain, has grown beyond the scope of automation, currently focusing on the occupant centered approaches and the ancillary services offered to the power grid. The Internet of Things (IoT) introduced in the recent years are enabling those prospects. However, due to numerous legacy automation systems already in the construction market, the IoT based intelligent building approach is frequently challenged. This paper assesses the opportunities along with the criticism for a fully IoT enabled and controllable intelligent building against the well established, legacy automation systems in a fair and transparent approach. In the second part, it proposes an interoperable intelligent building design for the creation of advanced building managements schemes, by integrating the assets of current automation tools and the emerging innovations. This unification and the progressive phasing out of legacy technologies, would catalyze the market of intelligent buildings in the context of smart cities by not limiting their potential solely on new constructions and by mitigating the investment if legacy systems are already installed.

An Event-driven Low Power Electronics for Loads Metering and Control in Smart Buildings

The Internet of Things market is experiencing a period of intense growth. From 7 to 10 billion of connected devices in 2013, it is expected to reach 26 to 30 billion in 2020. Smart buildings represent between 2 to 21% of this market. Indeed, the possibility of connecting objects changes the paradigms of measurement, monitoring and management within the building. This paper presents a miniaturized event-driven low power electronics device dedicated to electrical loads in the context of energy management and optimization systems. An electronic device for distributed intelligence is proposed. It is designed and intended to be added in the path of the power supply of existing electrical appliances. This device helps, as well, to perform local processing of measured data in order to provide a dedicated and optimized control of the connected load

A System for Wireless Power Transfer of Micro-Systems In-Vivo Implantable in Freely Moving Animals

A system for wireless power transfer of micro-systems in-vivo implantable in small animals is presented. The described solution uses a servo-controlled transmitter moved under the animal moving space. The solution minimizes the power irradiation while enabling animal speeds up to 30 cm/s. An x-y movable magnetic coil transmits the required power with a level able to keep constant the received energy. A permanent magnet on board of the implantable micro-system and an array of magnetic sensors form a coil tracking system capable of an alignment accuracy as good as 1 cm. The power is transferred over the optimized remote powering link at 13.56 MHz. The received ac signal is converted to dc voltage with a passive full-wave integrated rectifier and the voltage regulator supplies 1.8 V for the implantable sensor system. Experimental measurement on a complete prototype verifies the system performance
