Advances in information and communication technologies, ICT, are bringing new opportunities in the field of middleware systems oriented to ubiquitous environments and wearable devices used for patient telemonitoring. At a time of such challenges, this paper arises from the need to identify robust technical telemonitoring solutions that are both open and(More)
New use cases to extend the interoperability standard ISO/IEEE11073 (X73) were found during the development of recent specializations. These use cases expose the need of remote command and control extensions to allow managers to configure agents through the standard. This paper presents a proposal for an extension of remote control and configuration service(More)
Ambient assisted living and integrated care in an aging society is based on the vision of the lifelong Electronic Health Record calling for HealthCare Information Systems and medical device interoperability. For medical devices this aim can be achieved by the consistent implementation of harmonized international interoperability standards. The ISO/IEEE(More)
The new paradigm of personal health demands open standards and middleware components that permit transparent integration and end-to-end interoperability from new personal health devices to healthcare information system. The use of standards seems to be the internationally accepted way to face this challenge. In this article, the implementation of an(More)
The ISO/IEEE 11073 (x73) family of standards is a reference frame for medical device interoperability. A draft for an ECG device specialization (ISO/IEEE 11073-10406-d02) has already been presented to the Personal Health Device (PHD) Working Group, and the Standard Communications Protocol for Computer-Assisted ElectroCardioGraphy (SCP-ECG) Standard for(More)
A proof-of-concept design of a patient monitoring solution for intensive care unit environments has been presented. It is end-to-end standard-based, using ISO/IEEE 11073 (X73) in the bedside environment and EN13606 to communicate the information to an electronic health-care record (EHR) server. At the bedside end, the system is a plug-and-play sensor(More)
In this work, a novel ambulatory ECG monitoring device developed in-house called HOLTIN is analyzed when operating in complex indoor scenarios. The HOLTIN system is described, from the technological platform level to its functional model. In addition, by using in-house 3D ray launching simulation code, the wireless channel behavior, which enables ubiquitous(More)
This paper explains the challenges encountered during the ISO/IEEE 11073 standard implementation process. The complexity of the standard and the consequent heavy requirements, which have not encouraged software engineers to adopt the standard. The developing complexity evaluation drives us to propose two possible implementation strategies that cover almost(More)
The newest branch of the ISO/IEEE 11073 (X73) standard for Personal Health Devices (X73PHD), allow the development of interoperable personal health ecosystems. At the moment of this writing, more than 11 specializations have been successfully published by the Personal Health Device (PHD) Working Group (PHD WG). Nevertheless, some recent specializations at(More)
In this paper several approaches to implement the ISO/IEEE11073 interoperability standard into personal health devices using low-voltage low-power (LV-LP) microcontrollers are proposed. The patterns methodology previously suggested by the authors is followed in all of the approaches which include an 1-process implementation using non-blocking functions,(More)
