Wireless power transmission: R&D activities within Europe

Wireless power transmission (WPT) is an emerging technology that is gaining increased visibility in recent years. Efficient WPT circuits, systems and strategies can address a large group of applications spanning from batteryless systems, battery-free sensors, passive RF identification, near-field communications, and many others. WPT is a fundamental enabling technology of the Internet of Things concept, as well as machine-to-machine communications, since it minimizes the use of batteries and eliminates wired power connections. WPT technology brings together RF and dc circuit and system designers with different backgrounds on circuit design, novel materials and applications, and regulatory issues, forming a cross disciplinary team in order to achieve an efficient transmission of power over the air interface. This paper aims to present WPT technology in an integrated way, addressing state-of-the-art and challenges, and to discuss future R&D perspectives summarizing recent activities in Europe.The work of N.

Email-based interoperability service utilities for cooperative small and medium enterprises

Email, interoperability service utility, SME cooperation, recommendation As most SMEs utilize email for conducting business, email-based interoperability solutions for SMEs can have a profound effect on their business. This paper presents a utility-like system to support specialized SMEs to improve their business via emails by providing system, semantic and process interoperability solutions for individual SMEs and network of cooperative SMEs. We describe the concept of Email-based Interoperability Service Utility (EISU) and a software framework that provides almost zero cost interoperability solutions.
