TL;DR: This report discusses continuous glucose monitoring in terms of its purposes, technologies, target populations, accuracy, clinical indications, outcomes, and problems.
Abstract: Continuous glucose monitoring provides maximal information about shifting blood glucose levels throughout the day and facilitates the making of optimal treatment decisions for the diabetic patient. This report discusses continuous glucose monitoring in terms of its purposes, technologies, target populations, accuracy, clinical indications, outcomes, and problems. In this context, the medical literature on continuous glucose monitoring available through the end of 2004 is reviewed. Continuous glucose monitoring provides information about the direction, magnitude, duration, frequency, and causes of fluctuations in blood glucose levels. Compared with conventional intensified glucose monitoring, defined as three to four blood glucose measurements per day, continuous monitoring provides much greater insight into glucose levels throughout the day. Continuous glucose readings that supply trend information can help identify and prevent unwanted periods of hypo- and hyperglycemia. The difference between an intermittent and a continuous monitor for monitoring blood glucose is similar to that between a regular camera and a continuous security camera for monitoring an important situation. A regular camera takes discrete, accurate snapshots; its pictures do not predict the future; it produces a small set of pictures that can all be carefully studied; and effort is required to take each picture. A continuous security camera, on the other hand, takes multiple, poorly focused frames; displays a sequential array of frames whose trend predicts the future; produces too much information for each frame to be studied carefully; and operates automatically after it is turned on. The two types of blood glucose monitors differ in much the same way: 1 ) an intermittent blood glucose monitor measures discrete glucose levels extremely accurately, whereas a continuous monitor provides multiple glucose levels of fair accuracy; 2 ) with an intermittent monitor, current blood glucose levels do not predict future glucose levels, but with a continuous monitor, trends in glucose levels do have …

TL;DR: A wireless, real-time pressure monitoring system with passive, flexible, millimetre-scale sensors, scaled down to unprecedented dimensions of 1 × 1 × 0.1 cubic millimeters is reported, which has broader applications in continuous wireless monitoring of multiple physiological parameters for biomedical research and patient care.
Abstract: Continuous monitoring of internal physiological parameters is essential for critical care patients, but currently can only be practically achieved via tethered solutions. Here we report a wireless, real-time pressure monitoring system with passive, flexible, millimetre-scale sensors, scaled down to unprecedented dimensions of 1 × 1 × 0.1 cubic millimeters. This level of dimensional scaling is enabled by novel sensor design and detection schemes, which overcome the operating frequency limits of traditional strategies and exhibit insensitivity to lossy tissue environments. We demonstrate the use of this system to capture human pulse waveforms wirelessly in real time as well as to monitor in vivo intracranial pressure continuously in proof-of-concept mice studies using sensors down to 2.5 × 2.5 × 0.1 cubic millimeters. We further introduce printable wireless sensor arrays and show their use in real-time spatial pressure mapping. Looking forward, this technology has broader applications in continuous wireless monitoring of multiple physiological parameters for biomedical research and patient care.

TL;DR: In this paper, a multi-sensor data acquisition system is presented for continuous monitoring, real-time analysis, and automated and personalized training of exercise, which is especially targeted to, cardiopulmonary monitoring for athletes for improving the efficiency and safety of exercise.
Abstract: A method and system is invented for continuous monitoring, real-time analysis, and automated and personalized training of exercise. The system embodies a multi-sensor data acquisition system to measure body sounds, body signs, vital signs, motions, and machine settings continuously and automatically. The system is able to capture the body sounds and other vital signs, analyze them, and report and display summarized results. The signal processing functions utilize a unique signal separation and noise removal methodology by which authentic signals can be extracted from interfered signals and in noisy environments, even when signals and noises have similar frequency components or are statistically dependent. The method and system will facilitate continuous monitoring, real-time analysis, and computerized evaluation of level of effort, physical stress, and resulting fatigue during physical activity or exercise. In addition, based on body sound data, or in combination with other monitored physiological signals, and knowledge of the individual and exercise being performed, the system will evaluate the person's physical performance and then act as an automated coach to guide exercise intensity and duration thereby optimizing and individualizing the training process. The invention is especially targeted, but not limited to, cardiopulmonary monitoring for athletes for improving the efficiency and safety of exercise, rehabilitation programs for out-of-shape individuals, and routine exercise of the general population.

TL;DR: In this article, a wind and structural health monitoring system (WASHMS) has been devised and operated by Highways Department to monitor the structure conditions of the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge and the Ting Kau (cablesstayed).
Abstract: Instrumentation and health monitoring of cable-supported bridges in Hong Kong involve the integration of instrumentation, analytical and information technologies with knowledge and experiences in design, construction, operation and maintenance of cable-supported bridges for continuous monitoring of performance throughout their life-span. A bridge health monitoring system, called the WASHMS (wind and structural health monitoring system) has been devised and operated by Highways Department to monitor the structure conditions of the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge and the Ting Kau (cable-stayed) Bridge. The main objective of instrumentation and health monitoring is to detect and evaluate any symptoms of operational anomalies and/or deterioration or damage that may induce adverse effects on service or safety reliability through the processing and analysis of data collected from transducers and sensors. This WASHMS is composed of six modules, namely, the sensory system, the data acquisition and transmission system, the data processing and control system, the bridge health evaluation system, the portable data acquisition system and the portable inspection and maintenance system. The monitoring items are in general classified into three categories, namely, the loading sources (or input parameters) which include: wind, temperature, traffic (highway and railway) and seismic loadings; system characteristics (or system parameters) which include: static influence coefficients and global dynamic characteristics; and bridge responses (or output parameters) which include: variation in geometric configuration (or displacements of the bridges), stress/strain distribution, cable forces and fatigue stress estimation. This paper introduces the system architecture of the WASHMS with a brief functional description of each module. Categorization of the monitoring parameters and corresponding monitoring procedures are also outlined. The applications of the monitoring results are illustrated by some typical graphical plots such as wind-rose diagrams, spectral analysis, bogie loading and remaining fatigue life assessment. For successful design and operation of a bridge health monitoring system, conclusions are drawn with reference to the integration of knowledge and experience in four aspects: (i) design, construction, operation and maintenance of long-span bridges; (ii) instrumentation technologies for collection and processing of data; (iii) graphical CAD and numerical analytical technologies for modeling and analysis; and (iv) information technologies for transmission, processing and visualization of data.
