In an increasingly mobile world, many citizens and professionals are frequent travellers. Access during unplanned care to their patient summary, their most essential health information in a form physicians in another country can understand can impact not only their safety, but also the quality and effectiveness of care. International health information technology (HIT) standards such as HL7 CDA have been developed to advance interoperability. Implementation guides (IG) and IHE profiles constrain standards and make them fit for the purpose of specific use cases. A joint effort between HL7, IHE, and HealthStory created Consolidated CDA (C-CDA), a set of harmonized CDA IGs for the US that is cited in the Meaning Use II (MU-II) regulation. In the EU, the Patient Summary (PS) Guideline recently adopted, cites the epSOS IG also based on HL7 CDA, to support cross-border care in the EU and inform national eHealth programs. Trillium Bridge project supports international standards development by extending the EU PS Guideline and MU-II in the transatlantic setting. This paper presents preliminary findings from comparing patient summaries in the EU and US and reflects on the challenge of implementing interoperable eHealth systems in the cross-border or transatlantic setting. © 2014 European Federation for Medical Informatics and IOS Press.

Since the release by the Federal Communications Commission (FCC) of a bandwidth of 7.5GHz (from 3.1GHz to 10.6GHz) for ultra-wideband (UWB) wireless communications, UWB is rapidly advancing as a high data rate wireless communication technology. As is the case in conventional wireless communication systems, an antenna also plays a very crucial role in UWB systems. However, there are more challenges in designing a UWB antenna than a narrow band one. A suitable UWB antenna should be capable of operating over an ultra-wide bandwidth as allocated by the FCC. At the same time, satisfactory radiation properties over the entire frequency range are also necessary. To choose an optimum antenna topology for ultra wideband (UWB) design, several factors must be taken into account including physical profile, compatibility, impedance bandwidth, radiation efficiency, and radiation pattern. The main challenge in UWB antenna design is achieving the very broad bandwidth with high radiation efficiency and small in size. Accordingly, many techniques to broaden the impedance bandwidth of small antennas and to optimize the characteristics of broadband antennas have been widely investigated in many published papers as listed in this article. Planar monopole antennas are good candidates owing to their wide impedance bandwidth, omni-directional radiation pattern, compact and simple structure, low cost and ease of construction. Further detail on various bandwidth enhancement techniques will be discussed in this paper. This paper focuses on UWB planar printed circuit board (PCB) antenna design and analysis. Extensive investigations are carried out on the development of UWB antennas from the past to present. First, the planar PCB antenna designs for UWB system is introduced and described. Next, the special design considerations for UWB antennas are summarized. State-of-the-art UWB antennas are also reviewed. Finally, a new concept (case studies) for the design of a UWB antenna with a bandwidth ranging from 3GHz-8GHz is introduced, which satisfies the system requirements for S-DMB, WiBro, WLAN, CMMB and the entire UWB. © 2005 - 2012 JATIT & LLS.

This paper presents an Ultra Wide Band Microstrip Yagi antenna with very good performance at four main operating frequencies (0.85, 2.4, 3.5 and 5.2) GHz. Numerical simulation results of our design show more than (-20 to -40) dB return loss at the bands of (0.85, 2.4, 3.5, 4.5 and 5.2) GHz and VSWR less than 1.7 at these frequencies. The simulation method based on finite element method (FEM) was applied by using HFSS simulator to obtain the optimized parameters in order to find the best design for this antenna. The antenna bands can be varied to be suitable for various wireless applications. Finally a fabrication to the final design has been implemented, and then a measurement performed to compare the actual results with those simulated. Measured return loss and VSWR of this antenna are presented to validate the results of simulation so that it give (0.85, 2.4, 2.75, 3.6, 4.2 and 5.3) GHz for the measured return loss results and the antenna VSWR ≤ 1.5 at (2.4, 3.5, 4.5 and 5.2) GHz. © 2005 - 2010 JATIT & LLS.

Objective. This paper addresses the role of consumers/end-users, in our case Persons with Disabilities, in the creation of new standards regarding the accessibility aspects in society and the usability of products for all. The United Nations declaration on the rights of persons with disabilities requires that action has to be taken. The measures to be promoted is to include persons with disabilities, representatives. Until now consumers/end-users are not well represented in standards development. This is partly because European standardization is a new field for consumers/end-users for which they do not have the expertise to jump into. It is therefore needed to involve users with disabilities in the field of standardization. USEM project. To improve consumer/end-user participation in standardization a training is developed in the USEM project, which is EU funded. The USEM-principles describe the conditions for active user participation. These are: 1. Partnership as a basis; 2. Users are members and/or representatives of user organizations; 3. Financing participation should not be a barrier for participation; 4. Accessibility of all relevant materials and premises is guaranteed; 5. Every partner guarantees respect and expertise; 6. Detailed plan for the project. Results. In the USEM project 27 trainees from 14 countries are trained to participate in standardization in the ICT-field. A few of them participated in standardization-related activities like joining telephone conferences in an ETSI working group or joining the CEN/CENELEC StandardDays. A networkday with the USEM trainees a year after the actual USEM-training showed that there are still some hurdles for success. These include the cost of participation, not many running projects to participate in, the insufficient accessibility for blind participants of the written material, and the dominance of industrial representatives. Conclusion. - Concrete actions/developments are needed for users to get involved and stay involved. - An active user organization is important for the backing of the representative of users in standardization. © 2011 The authors and IOS Press.

The Stand4All project is a response to a call for tenders by the European Commission's Directorate-General for Employment, Social Affairs and Equal Opportunities. Its goal is to increase the use of CEN/CENELEC Guide 6, which contains guidance on the inclusion of the needs of elderly persons and persons with disabilities during the standards development process. To reach this goal, the project consortium has developed and delivered training on standardisation in several locations in Europe and for two types of audience: persons with disabilities and members of standardisation committees. The training for persons with disabilities is meant to increase their effective participation in the standardisation process. The training for committee members is meant to increase their awareness and knowledge of accessibility issues faced by persons with disabilities. © 2010 Springer-Verlag Berlin Heidelberg. Source
