In many instances, this data may be generated at a specified 1/0 location and it needs to be transferred to the main memory of the computer system for further processing and interpretation. Speed of data transfer is of utmost importance. One possible and most widely used mechanism is the Direct Memory Access (DMA) for high speed data transfers. The other method is based upon the multi or parallel processing. The former method is more applicable in small to medium sized systems while the later is widely used in large systems. In this article, We will discuss the technical aspects of the DMA based data transfers which are well suited in the bio engineering environment.","PeriodicalId":297811,"journal":{"name":"Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127782903","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 technique processes video images of marks on a contact lens adhered to an eye. This method gives accurate and high-speed measurement , because clear and simple marks eliminate the complex image processing such as extraction of the marks. Accuracy of this measurement is 0.08' of standard deviation. The rotational angle is able to record and display on a computer with a sampling frequency of 30Hz.","PeriodicalId":297811,"journal":{"name":"Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126325302","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 goal of this study is the application of computer programs as a possible strategy in rehabilitation of children with cognitive problems. Four programs were designed to stimulate various basic brain functions: problem solving, categorization, logical sequence and spatial thought. The programs were tested on a group of 20 mentally retarded young subjects matched with a comparison group of 20 like subjects trained with ordinary techniques. The computer trained group showed a significant improvement in tests involving attention, motivation for learning and problem solving abilities. These results, in our opinion, would confirm the usefulness of specific software as a rehabilitative method in dealing with cognitive problems of children.","PeriodicalId":297811,"journal":{"name":"Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128124147","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}

These are attenuation, spatial resolution, scatter, and noise as well as linear and angular sampling. At present, serious controversy is the choice of angular data sampling. The question is whether angular data sampling around complete 360' rotation is necessary or a limited 180' arc would be sufficient. Data obtained from point source in addition to a three-dimensional analytical, non-stationary simulation study are used. The results of these studies have confirmed that the 180' reconstructed images suffer more severely than 360' images from variable geometric distortion.","PeriodicalId":297811,"journal":{"name":"Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125631369","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}

In order to more fully evaluate cardiovascular control mechanisms in the human, a full range of hemodynamic variables should be measured. Without the simultaneous measurement of stroke volume and cardiac output, with the calculation of peripheral resistance, data interpretation based on heart rate and blood pressure alone is severely limited. Impedance cardiography, because of its noninvasive nature and ease of application, is well suited for the study of cardiac performance in the general population, as well as, in the clinical setting.","PeriodicalId":297811,"journal":{"name":"Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125990300","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}
