In-bed Patients Behaviour Monitoring System

Falls on elderly people represent a significant health problem where having a permanent care personnel attention is the unique effective method to avoid them. As more is investigated on causes originating falls, more is known about pre fall conducts. This project studies in-bed patient behaviour with the purpose of detecting a fall before it happens, sending an alarm to the complete system. The work presented in this article is still being developed within the framework of INTEK projects founded by the Basque Government, in cooperation with Atica Innovation Company.

Virtual Laboratory for On-board ETCS Equipment

Available ETCS equipment suffered from a long process before being put into service, due to inconsistencies in the specifications and the inability of the laboratory certification procedures to completely address all the needs of the system testing. To overcome those problems, this paper presents a novel ETCS Testing Laboratory, which will help in the reduction of on-site testing amount, and a Golden Reference Model of the ERTMS on-board equipment, that will help in the interpretation of the current normative. The design, implementation, operation and validation of these developments will be presented in this research work.

ETCS's Eurobalise-BTM and Euroloop-LTM Airgap Noise and Interferences Review

Wireless communications interfaces are vulnerable to interferers and noise. The effect of interferers and noise in the system will depend on the robustness of the communication system and the criticality of the system. ETCS European Train Control System is a safety-critical system responsible for the train control and command. There are two ETCS constituents installed on the track with a wireless communication to the train, namely Eurobalises and Euroloops that communicate with Balise Transmission Module BTM and Loop Transmission Module LTM. This paper includes an analysis of the state of the art of noise and interferers and proposes the worst case scenarios to be used in the laboratory to measure the robustness of the systems against noise and interferers.

Wireless Communication Emulator Device and Methodology for the ETCS BTM Subsystem

Currently European Train Control System ETCS rollout is a major concern for train manufacturers and railway infrastructure managers. But available laboratory certification procedures do not completely address all the needs of the system, which leads to long and expensive field-testing. This research work proposes a new tool that reduces the required on-site testing amount. The BTM Wireless Communication Emulator WCE reproduces the potential interferers that can be found in the air-gap of the BTM wireless communication channel. That way, the laboratory testing procedures can emulate the behavior of the wireless channel in a more realistic way. The identification of the potential interferers to be included in the emulator has been done first, and the design and implementation has been carried out afterwards. Finally, the testing and validation of the tool has been completed.

Wireless Sensor for Intravenous Dripping Detection

Nowadays the use of wireless technologies provides a great benefit to the society. This article shows a wireless sensor network for Intravenous Dripping System, which can detect when an intravenous liquid, provided to patients in hospitals, run out, as well as detecting obstructions in the catheter. This way, the attention in sanitary centers is more efficient and immediate, as the observation of the state of the container will not need human supervision. The work displayed in this article is still being developed within the framework of INTER projects founded by the Basque Government, in cooperation with Atica Innovation.

Wearable wireless sensor network for the monitorisation of Parkinsonian patients using a novel mobility algorithm

Recent advances in the field of wireless sensor networks (WSN) include the creation of a new kind of these networks, called body sensor networks (BSN). These systems have been proven to be an enabling technology for the application domain of unobtrusive medical monitoring. In this paper a novel algorithm is proposed, which covers one of the main technological lacks regarding BSN: the mobility of the network itself. These algorithms have been proven using a BSN applied to the monitoring of the gait of patients affected by Parkinson disease (PD). This work is being developed with the participation of the University Hospital of Navarra (CUN).
