Play for Health (P4H) is a telemedicine service consisting of a telerehabilitation platform to improve cognitive and physical deficits through the use of serious games and various videogames controllers. This paper states that there are issues that could benefit the rehabilitation process using serious games. We present the P4H platform as an example of success in  telerehabilitation based on serious games.

This article includes the details of the experiment conducted at the University of the Balearic Islands related to organize a hackathon which involves interdisciplinary, Service-learning and enterprise internship. The goal of the activity is to increase the student motivation and their knowledges and skills. Results are analysed through post-test surveys.

This paper presents the new payload for Turbot, the SPARUS II AUV unit, manufactured by the University of Girona and recently acquired by the Systems, Robotics and Vision Group of the University of the Balearic Islands. The new payload has been entirely designed and integrated to host all elements necessary to perform visual 2D/3D mapping, optical (visual-laser) object reconstruction, acoustic and visual obstacle avoidance, and acoustic localization and communication. Several experiments in shallow waters of Mallorca show the validity of the sensor integration and operation for all the required tasks.

There is a growing interest in developing embedded systems capable of being deployed in dynamic environments that may change in unpredictable manners. When such systems are Distributed Embedded Systems (DESs) they must exhibit flexibility at all levels of their architecture, including the network. On the other hand, there is a clear trend in industry towards using Ethernet-based protocols at the network level of DESs. Nevertheless, Ethernet lacks appropriate support for real-time (RT) communications, mixing different RT traffic and on-line management of the Quality of Service (QoS). Several implementations of the Flexible Time-Tiggered (FTT) protocol over Ethernet were proposed to cope with these drawbacks. FTT is a master/multi-slave protocol that is able to simultaneously convey real and non-real-time traffic and provides mechanisms for dynamically changing the QoS of the network, including Admission Control (AC). The AC is a fundamental component for on-line network management, since it guarantees that each participant gets the required QoS. This paper presents the implementation in OMNeT++ of a simulation model of the AC in the FTT HaRTES switch as well as a preliminary performance study using that model.

Distributed Embedded Control Systems (DECSs) used for critical applications must usually abide by strict real-time and dependability requirements. Correspondingly, the FT4FTT project proposes a complete fault-tolerant (FT) architecture for RT DECSs. The Flexible Time-Triggered Ethernet (FTT-Ethernet) communication protocol fulfills the RT requirements, while the FT mechanisms added on top of it, which are based on channel duplication and active replication of nodes, provide the FT behaviour. Temporary faults affecting the channel or the nodes, which are the most probable type of faults in DESs, can manifest in such a way that a node replica loses its coordination with the others and, thereby, it also loses its communication and/or computation capability from then on, leading to attrition of the redundancy initially provided by the active replication of nodes. This paper describes the implementation and test of specific mechanisms that are devised to determine which replicas are temporarily faulty and to promptly reintegrate them.
