This paper describes a smart system to monitor high temperature in industrial applications. The solution includes a semipassive microchip which allows logging data and wireless reading. Protection for the electronics against high temperature environment is provided by a vacuum packaging. Thermal isolation at 150°C and 800°C ambient temperature allows the system to work properly during 14 and 2 minutes...
We report a new algorithm for the generation of the microimages ready for their projection into an integral imaging monitor. The algorithm is based in the transformation properties of the plenoptic field captured with an array of digital cameras. We show that a small number of cameras can produce the microimages for displaying 3D scenes with resolution and parallax fully adapted to the monitor features.
Integral imaging is a rising 3D imaging technique that can be considered the incoherent version of holography. In integral imaging the multiperspective information of 3D scenes is stored in a 2D picture. Such picture is nothing but a sampling version of the lightfield emitted by the 3D scene. The recorded lightfield can be used for many purposes. One is the display of 3D color scenes to audiences...
Integral imaging is a rising 3D imaging technique that can be considered the incoherent version of holography. In integral imaging the multiperspective information of 3D scenes is stored in a 2D picture. Such picture, composed by a set of elemental images, is obtained through a 2D array of microlenses. The elemental-images set can be used for many purposes. One is the display of 3D color scenes to...
Governments in under developing countries face serious problems for offering quality healthcare services at reasonable cost due to rapidly graying population and patients with chronic diseases. Due to currently healthcare resources are not sufficient, many deaths without medication are produced. Thus, this increasing important issue needs to be attended. Our approach to tackle this issue is based...
In this paper, a vision-based system to detect the eyelid closure for driver alertness monitoring is presented. Similarity measures with three eye templates (open, nearly close, and close) were calculated from many different features, such as 1-D and 2-D histograms and horizontal and vertical projections, of a big set of rectangular eyes images. Two classifiers, Multi-Layer Perceptron and Support...
This paper presents a novel implementation methodology of ISO/IEEE11073 standards for use in real monitoring platforms based on patterns paradigm. These monitoring platforms include several medical devices based on low voltage-low power microprocessors. As a proof of the concept, INTENSA project which aims to develop and evaluate a heart failure follow-up interoperable system including weigh scale,...
Continuous technological innovations are bringing new opportunities to healthcare applications. Although these improvements apply to most of its different fields, outstanding results are being achieved in medical devices interoperability, oriented to ubiquitous solutions including wearable devices, focused to the new paradigm of personal health (p-health). These evolutions can improve the quality...
Advances in information and communication technologies, ICT, are bringing new opportunities in the field of middleware systems oriented to ubiquitous environments and wearable devices used for patient telemonitoring. At a time of such challenges, this paper arises from the need to identify robust technical telemonitoring solutions that are both open and interoperable in home or mobile scenarios. These...
This paper reports concentration levels of 22 chlorinated organic compounds (both primary compounds and metabolites) in food marketed in the city of Barcelona (Catalonia, Spain) in 2001–06. Samples included meat products, fish and seafood, eggs, milk and dairy, vegetal oils, cereal products and derivates, vegetables, fresh fruits, dry fruits, spices, formula and baby food, tea and wine. Levels of...
The proposed method detects fetal R waves on abdominal non-invasive records. An exponentially averaged pattern of the mother PQRST segment is obtained and subtracted. Subsequently the fetal R detector based on a Smoothed Nonlinear Energy Operator (SNEO) is applied to the residual signal. Finally, criteria about amplitude, heart rate and backward search are settled to correct false detections. To evaluate...
