Fusing Multiple Sensor Modalities for Complex Physiological State Monitoring

Body health monitoring is so important to us for ensure that our health is in an excellent case. The systems for Health monitoring are a new subject and significant research scope nowadays. There are many significant vital parameters in the health observing systems, Heart Rate (HR) is one of the most important signs of these parameter to be monitor; it is a vital indicator of people’s physiological state. Monitoring of heart rate oftentimes includes high costs and complex application of sensors and its systems. Therefore to cover this needed it must advance systems that are able to measure HR and ECG systems for the purpose of monitoring. This paper focuses on reviewing the monitoring of the heart rate systems with the uses of a fingertip sensor and electrocardiogram other remote technologies. More than forty of the heart rate measuring and observing systems and Electrocardiogram systems have reviewed and grouped into two groups one for heart rate and the other for wearable ECG, presented its features and common specifications for each of them, resulting from this review that the authors have focused on designing systems that can be optimum choice for illness people which they have needed to be continuous monitoring. The systems are acceptable error rate and some of them allow the user to freely move based on the wireless technology, the systems easy for usage by the patient or elder people and with a suitable cost. Also, this paper presents security, personality, reliability of systems and the quality of the signal.

Cognitive Attention

Mental state changes induced by stimuli under experimental settings or by daily events in real life affect task performance and are entwined with physical and mental health. In this study, we developed a physiological state indicator with five parameters that reflect the subject’s real-time physiological states based on online EEG signal processing. These five parameters are attention, fatigue, stress, and the brain activity shifts of the left and right hemispheres. We designed a target detection experiment modified by a cognitive attention network test for validating the effectiveness of the proposed indicator, as such conditions would better approximate a real chaotic environment. Results demonstrated that attention levels while performing the target detection task were significantly higher than during rest periods, but also exhibited a decay over time. In contrast, the fatigue level increased gradually and plateaued by the third rest period. Similar to attention levels, the stress level decreased as the experiment proceeded. These parameters are therefore shown to be highly correlated to different stages of the experiment, suggesting their usage as primary factors in passive brain-computer interfaces (BCI). In addition, the left and right brain activity indexes reveal the EEG neural modulations of the corresponding hemispheres, which set a feasible reference of activation for an active BCI control system, such as one executing motor imagery tasks. The proposed indicator is applicable to potential passive and active BCI applications for monitoring the subject’s physiological state change in real-time, along with providing a means of evaluating the associated signal quality to enhance the BCI performance.

Technique Development

Microprobe analysis of biological tissue is now in the end phase of transition from instrumental and technique development to applications pertinent to questions of physiological relevance. The promise,implicit in early investigative efforts, is being fulfilled to an extent much greater than many had predicted. It would thus seem appropriate to briefly report studies exemplifying this, ∿. In general, the distributions of ions in tissue in a preselected physiological state produced by variations in the external environment is of importance in elucidating the mechanisms of exchange and regulation of these ions.

Dimensional Reconstruction

Chromatin structure at the fundamental level of the nucleosome is important in vital cellular processes. Recent biochemical and genetic analyses show that nucleosome structure and structural changes are very active participants in gene expression, facilitating or inhibiting transcription and reflecting the physiological state of the cell. Structural states and transitions for this macromolecular complex, composed of DNA wound about a heterotypic octamer of variously modified histone proteins, have been measured by physico-chemical techniques and by enzyme-accessibility and are recognized to occur with various post-translational modifications, gene activation, transformation and with ionic-environment. In spite of studies which indicate various forms of nucleosome structure, all current x-ray and neutron diffraction studies have consistently resulted in only one structure, suggestive of a static conformation. In contrast, two-dimensional electron microscopy studies and three-dimensional reconstruction techniques have yielded different structures. These fundamental differences between EM and other ultrastructural studies have created a long standing quandary, which I have addressed and resolved using spectroscopic electron microscopy and statistical analyses of nucleosome images in a study of nucleosome structure with ionic environment.
