OSAMI-D: An open service platform for healthcare monitoring applications

In this paper conceptions and architectural considerations of the OSAMI project and their specializations towards the requirements of the e-health domain by the German subproject (OSAMI-D) are described. Along with the expected shift of healthcare service between stationary towards ambulatory care, a standardized way of integrating medical data acquired at home into the IT infrastructure of hospitals and the synchronization with medical workflows have to be implemented. Therefore, the OSAMI-D project will provide open source components that implement the required interfaces. Preliminary results of the requirements analysis and the implementation of first domain-specific services are presented. These services are used to realize two home care scenarios, which support ambulant cardiologic rehabilitation (indoor and outdoor). Special emphasis is placed on standards and formats for the communication and storage of patient data.

An XML format based integration infrastructure for IP based design

IP based design comprises two main steps. First, a suitable IP has to be found. Second, the IP has to undergo further processing before it can be included in existing designs. Since IP providers use different formats and design tools require different parts of the IP for their services it is hard to find an IP format that satisfies and is exchangeable between all parties. This paper presents such a unified format. It can be used to search for, deliver and exchange IPs between the designer and external IP service providers. A tool chain based on the format was implemented and evaluated. The results prove its applicability.

Ontology-based context management components for service oriented architectures on wearable devices

Up-to-now wearable applications are built from individual optimized software components. This paper presents a structured approach to design and implement context-processing modules for context-aware systems and applications which significantly enhances reusability of this common component. Instead of monolithic, single purpose, context processing solutions, the authors suggest a generic approach to define contexts, and to employ a context management framework to realize the context-awareness services which complements the idea of an extensible wearable computing framework based on a service-oriented architecture developed by the European research project wearIT@-work.

Generic platform for advanced E-health applications

The demographic change and the cost pressure in the healthcare sector drive the need for efficient and secure medical homecare solutions which apply for the people who are elderly or in anastasis. As the complexity of such systems is rising, there is a need of a common foundation of components which can be reused to lower the implementation effort of such systems. The European ITEA2 OSAmI research project targets such a common foundation of basic components for a basic, widely applicable service-oriented component platform. The German OSAmI-D subproject develops a construction kit based on the OSAmI component platform with a particular focus on services for medical and E-Health applications. The results of the ongoing project and especially the foundation of reusable components are demonstrated in the scenario of home-based ergometer training during the rehabilitation of patients with cardiologic illnesses.

Embedded System Design Based On Webservices

The structure of Internet applications and scenarios is changing rapidly today. This offers new potential for established technologies and methods to expand their area of application. New technologies encourage new methodologies to design processes and business-to-business applications. The application of such new advancements should be extended into the domain of the electronic design automation (EDA) industry. In this paper we present an approach to use webservices in the field of embedded system design.

OSAMI Commons — An open dynamic services platform for ambient intelligence

Today we live in an environment surrounded with networked converging devices. Human computer interactions are becoming personalized and a new concept of a global and cross-domain platform is emerging to exploit the full potential of the network in all business areas. In this convergence process, the software platform should be able to personalize itself dynamically in devices according to the context. OSAmI-Commons, an ITEA2 project for developing an open-source common approach to such a dynamic service-based platform, allows any type of device to connect and exchange information and services. OSAMI consortium is contributing to defining the foundations of a cross-platform open-services ecosystem. The sustainability of this platform is an objective beyond the project duration.

Provision and Integration of EDA Web-Services Using WSDL-based Markup

This paper studies the integration of resources (e.g., tools used in electronic design automation) into environments used to implement collaborative engineering workflows. Major attention is paid to the consideration of resources that are available through the web. Requirements that are implemented in the integration approach comprise the support of concepts for re-use and the web standards. The latter is achieved by employing the Web Service Description Language (WSDL), an upcoming XML-based format for mark-up of services residing in the web.

Software IP In Embedded Systems

IP-based hardware design became an important topic during the past years. There is an even older tradition of reuse of software components. In this contribution we try to address some key problems of software reuse. First of all, in a bottom-up approach we study some underlying communication techniques used to couple different software components. As the most general solution of this problem is CORBA (Common Object Request Broker Architecture) from our point of view, this technique is discussed briefly. From the bottom we move directly to the top. The most flexible way of handling reusable software IP is to deal with their abstract model. Following this approach, modules can be embedded to various target environments using standard synthesis methods. The problem of protecting property in this approach is not discussed in this chapter. We concentrate on how to combine modules that have been modelled in various languages. At least when using a language coupling approach strict support to define bridging semantics has to be provided. A very useful means for this purpose is given by the ASM (Abstract State Machine) method, which is shortly introduced in the chapter. When software IP has to be used this IP resides on various databases in most cases. We discuss, how design workflows can be defined that allow to access such remote IPs. The exchange format XML plays an important role in this context. Finally we discuss an application example: the application-specific synthesis of real-time operating systems (RTOS) and real-time communication systems (RCOS) from a library of reusable and highly generic software modules.

How to integrate Webservices in Embedded System Design

The structure of Internet applications and scenarios is evolving rapidly. New software architectures and formats for transfer of data and site-spanning interoperability are emerging and reshaping the realm of web-centered computing. These changes are having repercussions that will change the established methodologies of design processes and business-to-business applications. Therefore, these effects on the domain of the electronic design automation (EDA) have to be considered and their validity shown.. In this paper we present an approach to exploit webservices technology in the field of embedded system design.

An approach for classification of integrated circuits by a knowledge conserving library concept

A simulation based analysis of analog and mixed analog/digital circuits on printed circuit board level requires a lot of information about the involved components. Entering solely the data sheet information into a component library normally disregards structural knowledge which is well-known by the circuit designer. Therefore, the expert knowledge necessary for an optimum use of analysis tools is no more available. This paper presents an approach to overcome this problem. A concept to represent efficiently expert knowledge and classification information is introduced and a classification of circuits which conserves the structural information is presented.
