This paper proposes a control architecture for driving a panel Braille, that works as an aid in the reading of information by visually impaired people and also for applications for teaching Braille. To validate a prototype it was developed containing the control algorithm, which uses two techniques together: the conversion of characters in dot matrix in software and hardware multiplexing signals, and both techniques are scalable to jointly control the display of Braille characters on the panel. The panel allows the rewriting and updating size to provide new operating parameters.

This paper reports on a study to investigate the feasibility of Thermal Reflective Multi-layer System (TRMS) as support for Disaster Resilience.\ud Design/methodology/approach\ud \ud It is an innovative insulation system, developed from space engineering studies, lightweight and is characterized by a thermal conductivity of 0.038 W/mK, making it a strong candidate for inexpensive shelter after disaster design.\ud Findings\ud \ud One of the results of this study is a proposal for the Air Shelter House (ASH), a new concept design of a shelter based on TRMS.\ud Originality/value\ud \ud The combined use of TRMS with low cost building materials and a 3D printer system for the construction joints provides a good comprise of building cost and energy efficiency performance. Such an innovative design supports disaster resilience during response, reconstruction and mitigation phases and is suitable for a wide variety of cultural and environmental situations where energy efficiency is important
