A novel elastic sensor sheet for pressure injury monitoring: design, integratio...
Amini, Mohammad Mohammad; Devin, Mohammad Ghassem Farajzadeh; Alves, Paulo; Sheikholeslami, Davood Fanaei; Hariri, Fatemeh; Dionísio, RogérioThis study presents the SENSOMATT sensor sheet, a novel, non-invasive pressure monitoring technology intended for placement beneath a mattress. The development and design process of the sheet, which includes a novel sensor arrangement, material selection, and incorporation of an elastic rubber sheet, is investigated in depth. Highlighted features include the ability to adjust to varied mattress sizes and the in...
Design of CAN Bus communication interfaces for forestry machines
Spencer, Geoffrey; Mateus, Frutuoso; Torres, Pedro; Dionísio, Rogério; Martins, RicardoThis paper presents the initial developments of new hardware devices targeted for CAN (Controller Area Network) bus communications in forest machines. CAN bus is a widely used protocol for communications in the automobile area. It is also applied in industrial vehicles and machines due to its robustness, simplicity, and operating flexibility. It is ideal for forestry machinery producers who need to couple their...
Literature review of machine-learning algorithms for pressure ulcer prevention:...
Ribeiro, Fernando Reinaldo; Fidalgo, Filipe; Silva, Arlindo F.; Metrôlho, J.C.M.M.; Santos, Osvaldo; Dionísio, RogérioPressure ulcers are associated with significant morbidity, resulting in a decreased quality of life for the patient, and contributing to healthcare professional burnout, as well as an increase of health service costs. Their prompt diagnosis and treatment are important, and several studies have proposed solutions to help healthcare professionals in this process. This work analyzes studies that use machine-learni...

Cyber-physical production systems supported by intelligent devices (smartboxes)...
Torres, Pedro; Dionísio, Rogério; Malhão, Sérgio; Neto, Luis; Ferreira, Ricardo; Gouveia, Helena; Castro, Helderndustry 4.0 paradigm is a reality in the digitization of industrial processes and physical assets, as well as their integration into digital ecosystems with several suppliers of the value chain. In particular, Industry 4.0 is the technological evolution of embedded systems applied to Cyber-Physical Systems (CPSs). With this, a shift from the current paradigm of centralization to a more decentralized production,...

All-optical multifunctional logic operations using simultaneously both interfer...
Reis, Cláudia; Chattopadhyay, Tanay; Parca, Giorgia; Dionísio, Rogério; André, Paulo; Teixeira, AntónioIn this paper, all-optical logic functions, implemented with a single SOA-based Mach-Zehnder interferometer (SOA-MZI), are demonstrated experimentally and through numerical simulations. The proposed optical configuration is capable to carry out four logic operations, using simultaneously both output ports of the SOA-MZI. This may reduce the power cost and make possible to obtain simultaneously multi logic funct...
Combination of a geolocation database access with infrastructure sensing in TV ...
Dionísio, Rogério; Ribeiro, Jorge Miguel Afonso; Marques, Paulo; Rodriguez, JonathanThis paper describes the implementation and the technical specifications of a geolocation database assisted by a spectrum-monitoring outdoor network. The geolocation database is populated according to Electronic Communications Committee (ECC) report 186 methodology. The application programming interface (API) between the sensor network and the geolocation database implements an effective and secure connection t...
