This study has developed a plantar pressure sensing device by utilizing the piezoresistive sensor array that has adopted Nano-technology and Screen Printing Technology. This sensor array has high linearity (>0.95), high repeatability(<5%), large range of pressure (2.54Mpa) and the high bending fatigue tolerance. Comparing the specification of this piezoresistive sensor array with other similar device, it can be considered as the thinnest sensor array, highest range of pressure and greatest number of sensors among the commercialized products.

Embedding pressure sensors into household fixtures enables unobtrusive occupant health and safety monitoring at home. To monitor bathroom grab bar use, the force applied to a grab bar is desired from the output of three embedded pressure sensors. We examine the measurement of applied force in a non-uniform pressure sensor array, where forces are distributed with spatial nonlinearity to the pressure sensors. Two methods that ignore the spatial nonlinearities are compared to two methods that incorporate them. These include a polynomial response curve, a theoretical model, a lookup table, and an artificial neural network. When many calibration points can be taken and location estimates are accurate, the location-based lookup table presented the lowest error. However when calibration time is limited, the theoretical model performs best, while an artificial neural network is preferred when location inputs are inaccurate.

Most football simulators available use computer simulation to mimic football motion in a virtual environment. These kinds of simulations, while fun and interactive, are primarily for entertainment rather than as a training tool. In this paper, we present a virtual training system for football kicking based on computer sensing and football impact dynamics using real-time wireless feedback. It is designed as a computer-assisted training system that will give a kicker the ability to practice off the field and receive the detailed feedback comparable yet more quantitative than they would experience at a training camp. In addition, it enables football coaches with quantitative data to design player-specific training program for kickers in order to achieve a goal with more precision. The system includes a force-sensing panel to determine the position and velocity as initial data, real-time wireless feedback to calibrate the football kicking dynamics model, and an advanced visualization environment designed to recreate the realistic atmosphere of all major football stadiums. The system has been designed and tested in a lab environment. The preliminary results show that the wireless signal is sensitive enough to detect football positions on the fly. The data collected in real-time can be used to calibrate the football dynamics model in predicting the final position of the football with respect to the field goal, which is visualized using 3D stereoscopic technology.

Breathing patterns are useful clinical parameters that may have more potential than is currently realized for palliative care patients. However, continuous respiratory monitoring is not feasible or appropriate, given the goals of end-of-life care. Recent advances in unobtrusive sensing could allow palliative care patients to be monitored from their bed. A pressure sensor array was placed into the beds of two palliative care patients in a palliative care ward and four healthy participants at home. A number of common disordered breathing patterns were identified from the extracted respiratory signals of the palliative care patients. Trends in a proposed index of respiratory amplitude and interval disturbance (RAID) uncovered periods of respiratory disturbance for the palliative care participants as well as the healthy participants. This study demonstrates that bed-based respiratory monitoring of palliative care patients is feasible in both hospice and home settings.

Assessing a patient's standing stability provides information to clinicians when monitoring a patient's recovery after a stroke or hip surgery. This paper explores the usability of pressure sensitive floor sensors for capturing clinical information related to standing stability. The configurable parameters of the sensor array;sampling rate and resolution are varied to design a system that is efficient and effective in presenting data to clinicians. An algorithm using image processing techniques was developed to calculate the patient's center of pressure (COP). The location of the COP is used to determine how symmetrical the patient's stance is. While investigating the impact of reducing the sampling rate and resolution of the pressure sensor, a trade-off between bandwidth and accuracy was discovered. However the results show that the minimum sampling rate to obtain >95% accuracy was 3.3 Hz and the minimal resolution to obtain >90% accuracy used only 1/4 of the sensor array.

In this paper, a personal micronavigation system that uses high-resolution gait-corrected inertial measurement units is presented. The goal of this paper is to develop a navigation system that uses secondary inertial variables, such as velocity, to enable long-term precise navigation in the absence of Global Positioning System (GPS) and beacon signals. In this scheme, measured zero-velocity duration from the ground reaction sensors is used to reset the accumulated integration errors from accelerometers and gyroscopes in position calculation. With the described system, an average position error of 4 m is achieved at the end of half-hour walks.

Background and objective: The SD-101 is a non-restrictive, sheet-like medical device with an array of pressure sensors, to detect sleep-disordered breathing by sensing gravitational alterations in the body corresponding to respiratory movements. This study evaluated the accuracy of the SD-101 for screening sleep apnoea-hypopnoea syndrome (SAHS) by comparison with polysomnography. Methods: Nocturnal polysomnography and SD-101 monitoring were conducted simultaneously and compared in 201 patients with suspected SAHS (suspected SAHS group) and 165 male employees of a transport company (screening group). Results: Polysomnography revealed an AHI of <5, 5 <= AHI < 15, 15 <= AHI < 30, 30 <= AHI < 60 and AHI >= 60 events/h in 39, 35, 38, 68 and 21 subjects in the suspected SAHS group and 103, 34, 12, 12 and four subjects in the screening group, respectively. Central SAHS and obstructive SAHS were subsequently diagnosed in 11 (5.5%) and 135 (67.2%) of subjects in the suspected SAHS group and five (3.0%) and 39 (23.6%) of subjects in the screening group, respectively. Significant correlations were apparent between AHI and the respiratory disturbance index (RDI) measured with the SD-101 in both the suspected SAHS group (r = 0.88) and screening group (r = 0.92). Receiver operating characteristic curve analysis revealed 89.5% sensitivity and 85.8% specificity in identifying SAHS, using an RDI of 14.0 events/h. Conclusions: These findings suggest that the SD-101 is a useful device for screening SAHS.

pressure sensors can be used to unobtrusively obtain breathing signals from a person in bed. Obtaining a single representation of the breathing signal from an array of such sensors requires data-level fusion. We propose a decision directed adaptive linear estimator to perform this fusion online. The proposed method was compared with three other online fusion methods and two offline methods using one hundred data records collected from five healthy participants. The decision directed adaptive linear estimator had signal to noise ratios comparable to the offline correlation method that it was adapted from and better mutual information results. In the presence of movement noise and for low amplitude signals, the proposed method also provides good fusion performance.

Mechanical imaging: A new technology for medical diagnostics

引用

INTERNATIONAL JOURNAL OF MEDICAL INFORMATICS 1998年第2期49卷 195-216页

作者： Sarvazyan, A Artann Labs N Brunswick NJ 08530 USA

Mechanical imaging (MI) is a newly developed modality of medical diagnostics based on reconstruction of tissue structure and viscoelastic properties using mechanical sensors. The essence of MI is the solution to an inverse problem using the data of stress patterns on the surface of tissue compressed by a pressure sensor array. Imaged tissue structures are presented in terms of their visoelastic properties. Evaluation of tissue 'hardness' (shear elasticity modulus) provides a means for characterizing the tissue, differentiating normal and diseased Conditions and detecting tumors and other lesions. In contrast to the other existing methods of medical imaging which use sophisticated hardware such as superconductive magnets, expensive X-ray equipment and complex ultrasonic phased arrays, MI hardware consists of inexpensive mechanical sensors and a positioning system connected to a PC. A key feature of MI is 'knowledge-based imaging'. To produce a three-dimensional image, the computer uses both the measured parameters of an individual examined object and a general database on anatomy and pathology of the object. Two applications of MI are currently being developed: MI for mass screening and detection of breast cancer and MI for imaging the prostate and diagnosing prostate diseases. ii prototype of the device for mechanical imaging of the prostate has been developed and is being tested clinically at the Robert Wood Johnson Medical School, New Jersey. The device is comprised of a transrectal probe with a position sensor and a pressure sensor array mounted on the articulated rip, an electronic unit and a PC. Results of extensive laboratory studies with rubber prostate models and initial data obtained in clinical trials strongly suggests that for certain applications the MI technology, as a new modality of imaging, has a diagnostic potential comparable to that of conventional diagnostic technologies. Mechanical imaging of the prostate appeared to be an efficient means of obj
