Ubiquitous and plug-and-play are fundamental characteristics for the development of wireless sensor networks (WSNs). The ISO/IEC/IEEE 21451 family of standards has recently awakened its interest in this development, making easier the introduction of both characteristics in the design of wireless sensor nodes. Dynamic reconfigurability is also an exciting topic that is gathering interest for the development of embedded systems and smart sensor nodes in the last few years. The use of dynamic reconfiguration increases the scalability and heterogeneity capabilities of the sensor network. However, the ISO/IEC/IEEE 21451 standards do not handle dynamically reconfigurable nodes and previously proposed frameworks do not include this capability into novel wireless sensor nodes. In this paper, an ISO/IEC/IEEE 21451 transducer electronic data sheet (TEDS) architecture for the management of reconfigurable WSNs nodes is proposed. To test the node architecture and validate its capability, the proposed TEDS was implemented for an environmental sensor network. © 2014 IEEE.

This study presents MoWebA, a navigational role-centric model driven development (MDD) proposal for web applications development. The approach was conceived considering a previous study of web methods and analysing some open issues. This article presents the fundamentals of the proposal; the methodological aspects for modelling and transformation processes; and the defined notations/techniques for modelling and transformation tasks, including their abstract and concrete syntax definitions. We include a summary of the validation experiences and main results, and a comparison against other related proposals, in order to highlight the main contributions of MoWebA.

This paper presents the development of a novel functional electrical stimulation (FES) system. New approaches in emerging rehabilitation robotics propose the use of residual muscular activity or limbs movements during the rehabilitation process of neuromotor. More ambitious projects propose the use of FES systems to restore or compensate motor capabilities by controlling existing muscles or subject limbs. These emerging approaches require more sophisticated FES devices in terms of channels, signals controls and portability. In the framework of HYPER project, such devices are being developed to support the main objective of the project: the development of neurorobots and neuroprosthetics to restore functional motor capabilities in patients who suffered cerebrovascular accidents or spinal cord injury. The presented portable FES system includes novel elec-trostimulator circuits and improved channel switching capacities to enable emerging approaches in rehabilitation robotics. © 2011 IEEE.

This paper presents a low cost system for the assessment, diagnosis and training of balance based on static posturography and functional electrical stimulation (FES). This system includes low cost technology as the Wii Fit Balance Board and the Kinect. The posturography is a complementary tool to clinical diagnosis, and allows to find sensory systems and inputs degraded by different pathologies. The presented system also allows to explore new rehabilitation techniques based on functional electrical stimulation. Precisely, this paper describes the implementation of a novel balance and posture control rehabilitation approach based on muscle synergies.

IEEE Conference on Intelligent Transportation Systems, Proceedings, ITSC | Year: 2010

The widespread use of electronic equipments and their integration into the vehicular system have become a necessity in the automobile industry. The Smart Transducer concept -along with IEEE Standard 1451- improves the scalability of these networked electronic devices into a vehicular system. This paper describes the design and implementation of a real-time environmental wireless sensor network that characterizes air quality in Asuncion, Paraguay. Mobile sensor devices in public transport vehicles provide an effective mechanism to develop an efficient solution for this characterization. The development of the sensor network is presented, and experimental results obtained for the characterization of the proposed environmental monitoring system are provided. ©2010 IEEE.
