Item The OCARIoT Data Acquisition App(Institute of Electrical and Electronics Engineers Inc., 2020-07) Barbosa, Paulo; Santos, Douglas; Lucena, Caio; Bastida, Leire; Ferreira, Jose Fernando; Cea, Gloria; de Herrera, Alba Garcia Seco; Rodriguez Gonzalez, Alejandro; Santosh, KC; Temesgen, Zelalem; Kane, Bridget; Soda, Paolo; ADV_INTER_PLATWe introduce the OCARIoT Data Acquisition App, a mHealth open source solution that synchronizes and manages data in Health IoT pilots. It was developed during the H2020 project entitled OCARIoT (Smart childhood Obesity CARing solution using IoT potential) and is innovative in the sense that it allows efficient IoT data collection, integration of different commercial devices, improves the user's privacy, data's security and the management of data controllers respecting legal and ethics policies. The application acts as a token manager for accessing external services. Besides the main features of the application, we report the integration of Fitbit services, and the deployment in four Health IoT pilots in Brazil, Greece and Spain. A survey was conducted with users in these three pilots and collected information about their user experience. The results presented excellent feedbacks from the users, with initial needs of synchronizing different children's accounts and privacy, which justified the development of the tool. Finally, we got feedback of improvements in ethics, technological and reuse in Health IoT pilots.Item Safety Case Driven Development for Medical Devices(SPRINGER INT PUBLISHING AG, GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND, 2015-11-25) Ruiz, Alejandra; Barbosa, Paulo; Medeiros, Yang; Espinoza, Huascar; Koornneef, Floor; van Gulijk, Coen; Quantum; Tecnalia Research & InnovationMedical devices are safety-critical systems that must comply with standards during their development process because of their intrinsic potential of producing harms. Although the existing trend of an increasing complexity of medical hardware and software components, very little has been done in order to apply more mature safety practices already present on other industrial scenarios. This paper proposes a methodology to enhance the Model-Based System Engineering (MBSE) state-of-art practices from the safety perspective, encouraging the use of safety cases and providing guidance on how to show the correspondent traceability for the development artifacts. We illustrate our methodology and its usage in the context of an industrial Automated External Defibrillator (AED). We suggest that medical device industry could learn from other domains and adapt its development to take into account the hazards and risks along the development, providing more sophisticated justification, as, for example, the impact of design decisions.
