The aim of this research is to extend the current augmentative and alternative communication (AAC) system to wireless telecommunication service, for speech-impaired subjects. A pocket personal computer (PPC) with a Global System for Mobile Communications (GSM) module is adopted herein. The touch screen of PPC with designed graphics icon can be used as large buttons to activate the high-fidelity sound that is in turns sent to the GSM module for \"talking\" through the phone. An AAC layout editor is used to link the pre-recorded sound to the graphics icon and to compile the icon-based graphics for each individual. In addition, levels of dynamic linkages, including script-based, category of use, semantic linkage, and frequency of use are implemented for assisting the speech impairment user to retrieve these pre-stored conversational items which can speed up the communication rate.","PeriodicalId":386546,"journal":{"name":"2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116877830","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}

Three males and seven females in the age range 41-72 years (mean 56, SD/spl plusmn/10) participated in a within subject repeated measure study. The study consisted of two major testing protocols. The first was an objective passive movement protocol, which utilized a KIN-COM/sup /spl reg// dynamometer to measure range of motion (ROM) and evoked resistive torque during elbow extension. The second was an electromyographic (EMG) protocol, which allowed recording of EMG from 10 shoulder and arm muscles during the controlled passive elbow extension as the last component of ULTT1. A battery-operated micro-switch held by the subject, generated digital rectangular pulses to indicate occurrence of pain onset and pain tolerance limit during the experimental task. There was increased level of EMG activity prior to pain onset (P<0.05). There was also clear evidence that elevated perception of pain and elevated levels of resistive torque (P<0.05), were positively correlated with the EMG activity in the muscles responsible for antalgic posture of the upper limb (P<0.05). From these findings, now it is possible to propose that increased detectable resistance during elbow extension at ULTT1 position involves the protective reflex activation of the shoulder and arm muscles which is mediated by nociceptive and mechano-receptors as a result of the preferential mechanical stretching of the median nerve during the test.","PeriodicalId":386546,"journal":{"name":"2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117278944","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 study presents an attempt to clinically validate AT imaging in two patients with WPW-syndrome. We acquired 62-channel ECG mapping data during treatment in the catheter laboratory. The individual torso geometry was obtained by magnetic resonance imaging. Based on this data the AT map was estimated for the entire ventricular surface off-line for validation purposes. The AT maps were computed for a pacing protocol in the region of the right ventricular apex and for sinus rhythm beats prior and after successful pathway ablation. For paced beats the first onset activation was always found to be located in the apical region of the right ventricular endocardium. For beats in sinus rhythm prior to pathway ablation the location of the first onset of activation matched with the anatomic position of the ablation catheter during successful ablation. After the treatment this spot of early basal activation disappeared in the computed AT maps. Thus, we conclude that noninvasive AT imaging from ECG mapping data presents a novel clinical tool for assessment of cardiac electrical activation In reference to the associated anatomy.","PeriodicalId":386546,"journal":{"name":"2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128796805","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 experiments were done for its water solutions in the concentration range from 3.13/spl times/10/sup -7/ to 8.00/spl times/10/sup -5/ M, and some photophysical parameters have been experimentally determined for the lowest singlet excited state of ME2906. It was confirmed that ME2906 molecules were in the isolated molecular state below 1.00/spl times/10/sup -5/ M. It was also confirmed that the fluorescence in this concentration range was ascribed to the electronic transition from the lowest singlet excited state to the ground state. It was found that, above 1.00/spl times/10/sup -5/ M, a part of ME2906 molecules form dimers in water solution, which causes the red shift of the fluorescence spectrum and the enhancement of fluorescence in the 700-750 nm wavelength region. Semiempirical molecular orbital calculation revealed that the sodium aspartate attached to the tetrapyrrole ring through the ethanoic acid group was remarkably bent with respect to the tetrapyrrole plane, which seems to hinder the formation of Me2906 dimers up to 1.00/spl times/10/sup -5/ M.","PeriodicalId":386546,"journal":{"name":"2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128611497","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}
