This previously developed network utilizes Crossbow MICAz motes to create a wireless network to gather data, which is sent to a central monitoring station. It includes a graphical user interface to store and display incoming measurements for all patients being monitored. Here the range of the network is extended by interfacing a GSM modem to the wireless sensor base station, allowing critical data to be forwarded anywhere in the world and providing a remote query mechanism via the existing cellular infrastructure. Text messaging using short message service is used as the communication interface. A priority message handling layer is added to the current protocol to insure delivery of critical data to the monitoring station and from there to medical personnel via the existing cellular infrastructure.","PeriodicalId":333843,"journal":{"name":"2007 IEEE Dallas Engineering in Medicine and Biology Workshop","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130532689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This system is an extension of the visible hyperspectral imaging prototype developed at the National Institutes of Health, NIH. It uses visible and near-infrared, NIR, light and electro-optical components to obtain spectroscopic images, thereby rendering the name multimodal. The goal of this research plan is to fabricate and utilize this system for monitoring wound healing in below the knee amputations. The system illuminates the amputation area with a cold broadband light source, collects a series of spectroscopic images spanning the visible and NIR, in parallel, deconvolutes the acquisitioned hyperspectral data using chemometric methods for imaging the spatial distribution of inherent chromophores. This technique is non-invasive, eliminates the use of contrast dye injection. The images produced visualize changes in the deeper larger blood vessels, provided by the NIR component and the superficial microvascular capillaries, provided by the visible component.","PeriodicalId":333843,"journal":{"name":"2007 IEEE Dallas Engineering in Medicine and Biology Workshop","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122354630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus of this research is to provide a step forward towards pervasive health monitoring. We describe a system to remotely monitor data from a patient's electrocardiogram (ECG). The data is transferred to a central monitoring station via a wireless sensor network for display. Crossbow MICAz motes are used as the network nodes. One of the nodes is interfaced with a commercial 3-lead ECG module and others are used to route the data through the network. A graphical user interface is designed for monitoring the cardiac rhythm. The primary objective of this experiment is to wirelessly transmit streaming ECG data in real-time with high reliability and minimal packet loss. Test results indicate a high reception ratio while transmitting ECG data over multiple hops.","PeriodicalId":333843,"journal":{"name":"2007 IEEE Dallas Engineering in Medicine and Biology Workshop","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126460423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Active noise control systems employing delayless subband adaptive filters have been shown effective in fMRI acoustic noise reduction [3] [4]. In this method [5], adaptive filtering is done in subbands and the subband weights are stacked together to construct the fullband filter weights. There are two types of stacking methods called FFT and FFT-2. These stacking methods introduce distortion which limit the noise reduction level. In this paper, we model the distortion and analyze the effect of distortion when different adaptive schemes (nLMS, APA, RLS) are used. This analysis helps in selecting the appropriate adaptive scheme and determining the optimum number of subbands.","PeriodicalId":333843,"journal":{"name":"2007 IEEE Dallas Engineering in Medicine and Biology Workshop","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121378273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, not many studies have been conducted to investigate the adhesion of prostate cancer cells on vascular endothelium and related mechanisms and modulators. In this study, human microvascular endothelial cells (HMEC) grown on glass slides were exposed to two different circulating prostate cancer cells, PC-3 and PC-3ML (highly metastasis prostate cancer cells) using an in vitro parallel flow system. The gene profiles of HMEC, after exposure to prostate cancer cells, were also investigated using cDNA microarrays. It was found that PC-3ML cells had significantly higher adhesion than PC-3 cells on HMEC monolayer. In addition, PC-3ML cells triggered more gene changes of HMEC than PC-3 cells did. These results suggested that prostate cancer cells might increase their adhesion to vascular endothelial cells by affecting the endothelial cell on the gene expression level.","PeriodicalId":333843,"journal":{"name":"2007 IEEE Dallas Engineering in Medicine and Biology Workshop","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121662726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The field has some specific needs that are different to many conventional electronics applications. Low power operation is essential but with intermittent high power requirements and the need for long term reliability. Conversely, circuit operating speed requirements are often extremely low; including monitoring at only a few KHz. Data storage (memory) requirements may also be relatively low. Furthermore, the operating temperature range of implanted devices is low compared to many non-implantable applications. These requirements together are assessed against the unique attributes of silicon on insulator (SOI) as a semiconductor material of choice for this environment, compared to that of conventional 'bulk' silicon.","PeriodicalId":333843,"journal":{"name":"2007 IEEE Dallas Engineering in Medicine and Biology Workshop","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125510013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent advances in inertial sensing technology have spawned interest in capturing motion information from multiple degrees of freedom (DOF). Our current interest is in the formation of a valid, single number composite score that answers the basic question: \"How steady is the body segment under test?\" Two approaches to steadiness composite score formation are investigated: 1) the traditional method that relies on addition, and 2) a new performance theory-based approach. Conceptual and experimental investigations were performed. The latter involved previously published 4 DOF data from 20 healthy subjects. It is shown that the multiplicative, performance-theory based composite score has better intrinsic validity and is more sensitive.","PeriodicalId":333843,"journal":{"name":"2007 IEEE Dallas Engineering in Medicine and Biology Workshop","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126840051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
