In order to provide a useful solution to chronic patients of all ages--with particular attention to the elderly--who are subjected to complex therapeutic regimen, an innovative ICT solution, called Dr.Drin, has been designed and tested. The aim of the developed framework is to assist the patient during the therapy and to enable and support a bidirectional communication between all healthcare stakeholders (doctors, caregivers and family members) and the patient. During the screening phase, patients were interviewed to understand what are the common practices they usually adopt to remember when and how to take a drug. The solutions which they rely the most on are the list of drugs, writing on the packaging, and setting up alarms. Patients who complained about difficulties of adherence and who had a smartphone were subsequently recruited to test Dr.Drin over a three-months period. In the following, preliminary resul...

This version of the kernel is especially targeted for an educational audience, that wants to experiment embedded system design, real-time scheduling and wireless communication on a simple inexpensive platform such as the LEGO Mindstorms RCX. The kernel architecture provides support for advanced scheduling algorithms and primitives, and for the standard devices available on the LEGO Mindstorms. A radio frequency module that interact with the RCX IR sensor has also been developed to enable easy cooperation between different entities. A case study is finally presented showing how ERIKA Educational can be used to create small networked embedded control systems.

Servers are restricted according to the principle of least privilege. For example, access to resources such as system memory and device I/O is fully protected. Although MINIX 3 is a potential candidate for embedded platforms, it currently cannot safeguard processes with stringent timing requirements, such as real-time applications.

New technologies are making their way in the area, including embedded real-time systems, standard local area networks like Ethernet, Wi-Fi and ZigBee, IP-based communication protocols, standard Service Oriented Architectures (SOAs) and Web Services. An automation system will be composed of flexible autonomous components with Plug & Play functionality, self configuration and diagnostics, and autonomic local control that communicate through standard networking technologies. However, the introduction of these new technologies raises important problems that need to be properly solved, one of these being the need to support real-time and quality-of-service (QoS) for real-time applications. This paper describes a SOA enhanced with real-time capabilities for Industrial Automation. The proposed architecture allows for negotiation of the QoS requested by clients from web services, and provides temporal encapsulation of individual activities. This way, it is possible to perform an a priori analysis of the temporal behavior of each service, and to avoid unwanted interference among them. After describing the architecture, experimental results gathered on a real implementation of the framework (which leverages a soft real-time scheduler for the Linux kernel) are presented, showing the effectiveness of the proposed solution. The experiments were performed on simple case studies designed in the context of industrial automation applications. ).
