A high accuracy localization of the order of millimeters is required for endoscopic applications. Location estimation of a capsule endoscope in the gastrointestinal (GI) tract is a challenging problem, as radio frequency signals encounter a high loss and highly dynamic channel propagation environment. In this paper, the characteristics of radio frequency signal absorption inside the human body are investigated with the aim of developing an accurate propagation model. Furthermore, the possibility of using a radar system for capsule localization is investigated and compared to its operation in the 2.4G Hz ISM band.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115286118","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, the 2.4 G Hz Industrial, Scientific and Medical (ISM) band, which is one of candidate frequency bands for WBAN, is not rich in diffraction, so when a man putting on on-body sensor nodes and a BAN coordinator takes different postures and actions, the direct links between them are frequently blocked by parts of his body, resulting in a higher packet error rate (PER). This paper proposes a cooperative relaying scheme for lowering the PER in a WBAN. For each node on a human body, the proposed scheme autonomously assigns a node as a cooperator out of other nodes and the cooperator re-transmits packets from the node for a BAN coordinator instead when the direct link between them is blocked. The paper evaluates the performance of the proposed scheme in terms of average and worst outage rates using experimental data for three subjects in a mixed indoor/outdoor environment.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127008749","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 perception of BCUs by the profoundly deaf has been objectively proven using magnetoencephalography (MEG). Furthermore, both the psychological characteristics and the neurophysiological mechanisms underlying the perception of BCUs have been identified by psychophysical, electrophysiological and physical approaches. In addition, we have developed a BCU hearing aid (BCUHA) for the profoundly deaf. Remarkable results have already been achieved with this device, which enabled 42 % of the profoundly deaf subjects in the trial to perceive some sort of sound and 17% of them to recognize simple words. These results suggest the feasibility of this device, but additional development and improvements are needed.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115188133","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}

Wireless BANs are generally divided into two kinds of groups, i.e., on-body BANs and in-body BANs. However, the performance requirements and channel propagation characteristics of the two BANs are quite different from each other, that is, wireless signals are approximately transmitted along the human body as a surface wave in on-body BANs, on the other hand, the signals are transmitted through the human tissue in in-body BANs. As a solution for this problem, this paper develops a structure of dual-mode transceivers, which is composed of transmitters for in-body and on-body communications and a receiver for the both communications. Then, we evaluate the communication performance of the dual-mode transceivers via a computer simulation with realistic channel models, which can well represent the propagation characteristics of on-body and in-body communications. Our computer simulation results demonstrate the feasibility of the dual-mode transceiver structure in wireless BANs.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130561902","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 systems are expected to have robustness against interference, low power consumption, and little interference from a human body. The most serious drawback is the shadowing problem due to a body in a hospital or home care bed. We confirmed by experiments and theoretical analysis that setting a coordinator near the ceiling and another coordinator under the bed is one of the best measures to prevent the shadowing problem. In this study, a shadowing model was used. A helical antenna having high antenna gain in the axial direction was used in the coordinator. In comparison with a biconical antenna, the helical antenna showed better radiation performance and less dependence on the angle direction of the antenna of the sensor node.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125477410","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}

Since the battery is flexible, it conforms to the shape of the diaper when the diaper is worn. The stress produce by the curvature presses the electrodes firmly against the diaper material, providing greater contact with any urine present. Thus, due to the curvature, the battery generates more power than when it is flat, as in an unworn diaper. The battery also acts as a wide ground plane for the antenna of a wireless transmitter, providing a large radiated power. To verify the effectiveness of the battery, we fabricated a battery and a prototype sensor and embedded the battery in a diaper. When 80 cc of urine is poured onto the diaper, the battery outputs a voltage of 1 V, which allows the sensor to transmit an ID signal over a distance of 5 m.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123807418","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 stroke neurologist has been conducting stroke education lessons for teens. However, efficiently conveying the information is difficult because the lesson has some limitations, including a shortage of physicians who can present the information. In this study, we have developed an online support system that enables schoolteachers to provide stroke education. This is a new approach. By using our system, schoolteachers can lecture to students on stroke signs, risk factors, symptoms and the FAST message (Facial droop, Arm weakness, Speech disturbance and Time of emergency call) for identifying typical symptoms of TIA. Additionally, we provide a web-based questionnaire survey for checking students' knowledge level. As a trial run of the system, we conducted a test lesson involving 78 students and a schoolteacher in a public junior high school. It was confirmed that the lesson could be conducted without trouble. On average, 70% of all students answered a question about the FAST message correctly. It was suggested that the function of the management side needs to be improved to increase the accuracy of the answer data. Our system could be used as a support tool for stroke education.","PeriodicalId":387991,"journal":{"name":"2013 7th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133966498","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}
