Display Autónomo para Elevadores
Gonçalo Lopes; Hugo Sá; Ernesto Martins; José Alberto Fonseca; António Garrido; Este artigo descreve sumariamente um sistema dedisplays universais e autónomos para equipar elevadores. Asolução desenvolvida consiste numa arquitectura distribuídade módulos inteligentes, munidos de displays gráficos do tipoLCD (liquid cristal display), ligados pelo barramento CAN(controller area network). Os módulos incluemmicrocontrolador PIC 18F, mem&oacu...
Unidade Remota de Telegestão e Controlo da Qualidade da Água
Isabel Veiga; Pedro Claro; Osvaldo Pacheco; Ernesto MartinsToday, public health issues and environment concerns place tight quality control requirements on the water used for human consumption. These can only be met by monitoring networks, and a careful control of the captation, storage and distribution systems.This paper presents the architecture of a remote unit thatworks both as a water quality monitoring system and as aremote management terminal.The remote unit acq...

A prognosis system for colorectal cancer
Oliveira, Tiago José Martins; Barbosa, Ernesto; Martins, Sandra; Goulart, André; Neves, João; Novais, PauloThe level of uncertainty and incompleteness in the information upon which healthcare professionals have to make judgments has been a subject of discussion in the past, and more nowadays, with the advent of the so-called Clinical Decision Support Systems. This work addresses uncertainty in the postoperative prognosis for colorectal cancer. The interdependence and synergistic effect of different clinical features...
A Coprocessor for Traffic Scheduling and Schedulability Analysis in FTT-CAN
Ernesto Martins; José Alberto FonsecaThe low-processing power microcontrollers typically used within CAN nodes, usually place tight limits on the complexity and flexibility of on-line message scheduling systems. One solution to break this barrier is to transfer the scheduling task to a hardware implementation.A preliminary version of a traffic scheduling and schedulability analyser coprocessor is proposed in this pape...
