- Sensor sem fios para monitorização da temperatura intra-corporalPublication . Mendes, Américo; Caldeira, J.M.L.P.; Moutinho, José Fonseca; Rodrigues, JoelA aplicação de novas contribuições científicas para a análise de processos fisiológicos deu origem a uma nova era na medicina, introduzindo técnicas e dispositivos para medição e monitorização de parâmetros fisiológicos. Este trabalho tem como objectivo a apresentação de um novo sensor de temperatura para medição e monitorização da temperatura intra-vaginal. Esta monitorização irá permitir estudar as variações deste parâmetro biológico ao longo de determinado período de tempo, como por exemplo, ao longo de todo um ciclo menstrual ou durante um dos dias desse ciclo. O conhecimento do comportamento deste parâmetro biológico poderá ser extremamente útil do ponto de vista clínico. Com base nesse conhecimento e nas suas correlações com determinados estados sintomáticos da fisiologia feminina, poderá ser possível estudar e propor novos métodos para combater a infertilidade dos casais, antecipar e monitorizar o período fértil (podendo ser usado, tanto para ajudar a favorecer a gravidez como apoio a métodos de anti-concepção), propor e ajustar terapêuticas de tratamento de inúmeras doenças ginecológicas, desenvolver novos métodos anti-concepcionais e ajuda à prevenção de partos pré-termo. O protótipo do sistema foi testado e validado com sucesso, estando pronto para utilização.
- A biosensor and data presentation solution for body sensor networksPublication . Neves, Paulo Alexandre; Caldeira, J.M.L.P.; Mendes, Américo; Pereira, Orlando; Rodrigues, JoelA Body Sensor Network can sense health parameters directly on the patient’s body, allowing 24/7 monitoring in an unobtrusive way. Several tiny sensors collect and route data to a special sink node. A new intra-vaginal biosensor was developed to study the relation between temperature variations and women health conditions, such as ovulation period, among others. We present a biosensor prototype and some initial results on real scenarios with a woman. One of the main issues in a body sensor network is the transformation of the sensor raw data into meaningful medical data for medical staff. Several approaches exist, from mobile device-based approaches to more powerful hardware such as a personal computer. This paper presents our current work in body sensor networks, namely a prototype for intra-vaginal temperature monitoring with initial results, and a mobile tool for data presentation of a three-tier body sensor network. The gathered results demonstrate the feasibility of the approach, contributing to the widespread application of body sensor networks.
- A novel intra-body sensor for vaginal temperature monitoringPublication . Rodrigues, Joel; Caldeira, J.M.L.P.; Vaidya, BinodOver the years some medical studies have tried to better understand the internal behavior of human beings. Many researchers in this domain have been striving to find relationships between intra-vaginal temperature and certain female health conditions, such as ovulation and fertile period since woman’s intra-vaginal temperature is one of the body parameters most preferred in such studies. However, due to lack of a appropriate technology, medical research devoted to studying correlations of such body parameters with certain womans’ body phenomena could not obtain better results. This article presents the design and implementation of a novel intra-body sensor for acquisition and monitoring of intra-vaginal temperatures. This novel intra-body sensor provides data collection that is used for studying the relation between temperature variations and female health conditions, such as anticipation and monitoring of the ovulation period, detection of pregnancy contractions, preterm labor prevention, etc.. The motivation for this work focuses on the development of this new intra-body sensor that will represent a major step in medical technology. The novel sensor was tested and validated on hospitalized women as well as normal healthy women. Finally our medical team has attested to the accuracy, usability and performance of this novel intra-body sensor.
- Accept mobile: a mobile tool for the SINMETRO accept information systemPublication . Caldeira, J.M.L.P.; Dias, Edgar; Paulo, Bruno; Neves, Paulo AlexandreIncreasing demand of mobile applications for on-site data acquisition pushes the development of flexible and easy to use mobile tools, with great advantages over the traditional computer-based approaches. The Accept System from SINMETRO allows data gathering for quality control, in the form of Inspection sheets. Such tool allows quality assurance by monitoring some samples of a given material, for instance milk, wine, and even maintenance management. This paper presents a mobile application in the Accept System that allows a Personal Digital Assistant (PDA) device to perform data gathering based on XML Inspection templates. Using .NET Compact Framework through C#, and database the technologies SQL Server and SQL Server CE, we developed Accept Mobile. Accept Mobile uses the Remote Data Access (RDA) mechanism to send data over to the server through a synchronization service, while also providing the needed support for disconnected operation. We prove that the mobile application is very convenient and provides enough functionality for the user to dismiss the portable computer, although the main application was never developed with mobility concerns in mind.
