Autonomous Wireless Sensors and RFID's: Energy harvesting, Material and Circuit Challenges
9 nov., 10 h 30, salle Europe, LAAS-CNRS
The presentation begins with an overview of energy considerations and challenges for low power system requirements in emerging applications such as health and smart homes, environmental monitoring, as well as an outlook of various energy harvesting technologies. The state-of-the-art in commonly used energy harvesting technologies such as solar, piezoelectric, thermal and electromagnetic is then presented. Figures of merit are provided and emphasis is placed on design challenges and novel technologies and materials, such as paper, textiles, inkjet printing.
Special focus is placed on hybrid–multiple technology harvesters leading to the development of low profile and conformal solar antennas and solar–electromagnetic harvesters. Design and optimization challenges are provided. Nonlinear circuit optimization combined with electromagnetic analysis is used to optimize circuit performance, and design methodologies for ultra-wideband and multiband RF energy harvesters are presented. Continued interest in electromagnetic energy harvesting is attributed to the minimum additional cost associated with its implementation due to existing antenna modules on wireless sensor nodes and RFIDs, as well as due to the capability for powering of wireless devices by intentional radiation known as wireless power transmission. The latter is addressed and novel system concepts such as transmission of chaotic signals for optimum performance are proposed. Circuit and system examples of autonomous system operation are demonstrated such as wirelessly powered sensors, beacon signal generators, energy harvesting applied to RFID systems. Finally, future perspectives and challenges are discussed in terms of energy storage, materials, and circuit performance and application scenarios.

He is an IEEE Senior Member and Chair of IEEE MTT-S TC-24 RFID Technologies. He is Chair of the IEEE MTT-S TC-24 RFID Technologies and Member of IEEE MTT-S TC-26 Wireless Energy Transfer and Conversion. He serves at the Editorial board of the Radioengineering Journal and as an Associate Editor of the IET Microwaves Antennas and Propagation Journal.
A LAAS team wins the security challenge of SSTIC
22 octobre 2012
Two researchers of TSF team, Eric Alata and Fernand Lone Sang, have
solved the SSTIC Challenge, and they are the only team awarded for the challenge. Three other individuals have been awarded for solving the challenge. For their solution, the TSF researchers had to develop their own reverse engineering tools (decompiler, debugger, emulator, etc.).
As part of the conference SSTIC, an annual challenge of security is offered to the scientific community around safety. The challenge this year was organized by CERT-Lexsi, EADS Innovation Works and ANSSI. It was to find an email address contained in an encrypted file itself stored in a corrupted hard disk image.
The all-terrain robot Mana from LAAS to ELROB
18 octobre 2012
Around 10 academic and industrial teams in Europe participate in these meetings designed to test the limits of capabilities of robots with a huge requirement.
LAAS participated to the ELROB event (European Land Robot Trial), held in Thun (Switzerland), Sept. 24-28. In this event all-terrain robots are tested realistic conditions in various scenarios: navigation, replay of previously learned trajectories, exploration of a given area. The laboratory has evaluated and demonstrated the autonomous navigation capabilities of the robot Mana, in particularly difficult conditions: woodlands, rough and slippery terrains...
The participation in this event helped to identify some issues (detecting water holes, locomotion control on slippery terrains). Developments carried out in the laboratory have also been validated, such as precise 100 Hz localization by fusing vision and inertial sensors, or a distributed architecture for the supervision of all the on board processes.
Best paper at ECEC'2012 conference
01 octobre 2012
Article "A Semantic Adaptive Framework for Collaborative System" by Aymen Kamoun, Saïd Tazi et Khalil Drira
Best paper, ECEC'2012, 18-20 April, 2012
Abstract
The collaboration environments are context sensitive; they may be subject of modification whenever parameters of use change. Dynamic adaptation is a key issue to enable continuity of collaboration and communication.
In this context, the collaborative development of products provides new challenges in distributed systems. It requires continuous communication and exchanges between teams of collaborators having different roles and using different tools. A global model of collaboration is necessary to guarantee the quality of communication and to ensure adaptability and interoperability between tools whatever may happen. In this paper, we present a framework for collaborative model-based services development that supports a semantic adaptation model. This framework enables a dynamic deployment of component that is triggered by the change of collaboration context such as the arrival/absence or change of roles and tasks of actors. In this article, the implementation of the framework and its conceptual model are presented. A test case for collaborative software development has been developed to validate the framework.
Furthermore, ECEC'2012 will feature a special workshop on Factory Planning and Control for Small and Medium sized Enterprises organized by the Polytechnic Institute of Castillo Branco in Portugal. The ECEC helps the dissemination of information and exploitation of results from the research and technical development and provides a forum for the exchange of experiences in developing and implementing CE based solutions across the wide spectrum of manufacturing and engineering industries. The conference is targeted at industrial enterprises, industrial associations, universities and research institutes.
European project Flagship Guardian Angels for a Smarter Life
31 mai 2012
The LAAS is a partner of the European Flagship Guardian Angels for a Smarter Life. Projects Flagships are large-scale initiatives to accomplish an objective scientific visionary to 10 years. The system developed in the Guardian Angels project will have applications for health, improving the city environment, monitoring of industrial environments and accident prevention.

The UseNet Projet obtains ITEA Achievement Award 2011 - Silver (Eureka)
29 février 2012
The ITEA 2 Board recognises the value of the UseNet challenge to free the machine-to-machine (M2M) market from the fragmentes vertical business syndrome through an open architecture. The great innovation of this project is the M2M Internet; separating M2M services forme M2M infrastructures drastically increases the size of the potential market for M2M deployments. UseNet has delivered an open architecture and has been very active in the new ETSI M2M TC standard. Highlights among the many exploitation cases include fast exploitation of the Ouman centralised remote control service system localisation of vehicles and ALU 5580 Home Network Manager evolution.
Each year, the ITEA Achievement Award highlights three concrete examples of best practice by aknowledging outstanding achievments - high-level technical contributions based on true European collaboration that lead to significant results and thus further promote the ITEA programme and its goals.
ITEA a pour objectif de rendre l'industrie européenne plus compétitive, l'exploitation industrielle des résultats du projet étant cruciale.
