The main reason is that the human body has to be considered as a highly complex nonlinear system. Many engineers and scientists have attempted to create a closed loop controller for sections of this system. This research focuses on the simulation of the musculo-skeletal function of the lower leg, based on the Pendulum Reflex Test data. The developed simulation of the lower leg can then be utilized in the design of new controllers, to be used in the control of Functional Electrical Stimulation (FES). These more intelligent systems will enhance the therapeutic effects of the FES devices.","PeriodicalId":448427,"journal":{"name":"Proceedings of the IEEE 21st Annual Northeast Bioengineering Conference","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125898729","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}

A simple and cost effective device called an aspiration condenser has been used for ion mobility analysis in a variety of gas monitoring applications. This device has the potential to become a competitive alternative to existing anesthesia monitoring technologies. This paper is a preliminary feasibility study of anesthetic agent identification, using an Artificial Neural Network (ANN), from ion mobility spectra obtained using an aspiration condenser. Spectra of the five commonly used volatile anesthetic agents (Halothane, Isoflurane, Enflurane, Sevoflurane, and Desflurane), in varying concentrations, were used to train and test an ANN. Preliminary results show an overall agent identification accuracy was 75% (concentration/spl lArr/1.0%) and 98.21% (concentration>1.0%). With further refinement of the measurement and analysis approach, a low-cost clinical anesthesia gas monitor can be developed.","PeriodicalId":448427,"journal":{"name":"Proceedings of the IEEE 21st Annual Northeast Bioengineering Conference","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123350233","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}

Much work has been dedicated to understanding the biology of the mechanisms involved in these processes. A major shortcoming of most studies is their inability to quantitatively assess the impact of various parameters on the quality of the new bone formed. The primary objective of this study is to demonstrate that such an analysis is possible with a scanning acoustic microscope (SAM). This technique will provide material property information about the newly formed bone regenerate on a microscopic level in terms of its acoustic impedance. The data presented here represents the information currently available in this ongoing study. At the time of this writing the data from eight animals was available for evaluation.","PeriodicalId":448427,"journal":{"name":"Proceedings of the IEEE 21st Annual Northeast Bioengineering Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114119821","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 the last decade, artificial neural networks have been shown to be a powerful tool for such pattern recognition tasks. Many signals are transient in nature, that is, they exist for only a limited duration in time. Moreover, much of the information in these transient bursts is conveyed by the dynamic evolution of the waveform in time the temporal structure of the signal. This is especially true of biological signals. Standard feedforward neural networks are not well-suited to capturing this temporal dimension. A neural network is described here that allows time to be represented implicitly within its structure, aiding its efficacy as a classifier of transient signals.","PeriodicalId":448427,"journal":{"name":"Proceedings of the IEEE 21st Annual Northeast Bioengineering Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131220846","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 memory capacity of the associated telemetry data acquisition systems is limited. In order to correctly evaluate the reliability of the sensor, long time data measurement are necessary. They may last several days and are performed with a constant sampling frequency on a sheep. The goal of our project is the optimization of the memory space.
