Realtime signal processing has been implemented using automatic DC calibration based on compressed sensing algorithm and ‘differentiate and cross-multiply’ (DACM) demodulation algorithm. Experimental results show that the proposed compact instrument based radar is able to measure respiration motions with simple hardware configuration. This facilitates many proof-of-concept studies for noncontact vital sign detection.","PeriodicalId":341652,"journal":{"name":"2014 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"210 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130158417","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}

It is a critical issue for health worker to provide a comprehensive, proactive health care in hospital, especially for those vulnerable patients who are unable to speak or behave for themselves. This study proposes an innovative, wearable RFID tag which embedded body temperature monitoring sensor, and equipped with automatic identification and localization, real-time emergency notification for health care workers. Additionally, operating with the intelligent backend system architecture, this system can also provide immediate physician advices in case if emergency situation happens without doctor near the site. The result of this study provides a ubiquitous medical care throughout whole hospital, and the new-invented tag may bring a significant change to normal health care process, especially in patient care.","PeriodicalId":341652,"journal":{"name":"2014 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131366757","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, in real applications random body movements during measurement will cause drift of “DC” level in the experiment results. Also, the dc level will shift slowly with the temperature change of the radar circuit. Those DC drifts will cause inaccurate measurement results. To solve the dc drift issue during the experiments, an automatic DC-correction algorithm is developed. Experiment results show that this algorithm eliminates undesirable DC drifts and offset while recovering useful information of the original respiration signal. It is able to provide reliable respiration measurement even if there are large body movements that otherwise overwhelm the desired signal.","PeriodicalId":341652,"journal":{"name":"2014 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124925020","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 inductive coupling based wireless power transfer technology has been the primary approach to remotely power an IMD [1]. Reducing the coil size and improving efficiency are the two primary design goals for the power harvesting component in an IMD. A pulse-width-modulated (PWM) boost converter has been demonstrated to efficiently convert the low-voltage (much less than the regular diode's turn-on voltage) AC power generated by a miniaturized receiving coil to a desired high-voltage DC power [2]. In [2], the switching frequency of the PWM is much higher than the frequency of the input AC power. The high switching frequency not only dissipates more power during the switching, which deteriorates the converter's overall efficiency, but also prevents the circuit from handling the high-frequency input AC power. In this paper, a low switching frequency AC to DC boost converter is demonstrated. By aligning the PWM signal with the input AC, the boost converter is able to convert the AC power, whose amplitude is 500 mV at the open-circuit condition, to a >5 V DC output. The converter demonstrated in this paper has the potential to significantly improve the conversion efficiency by reducing the dissipated power associated with the PWM switch, especially when the input AC is at higher frequencies.","PeriodicalId":341652,"journal":{"name":"2014 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133179157","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}

Analysis of two slot-type (annular and meandered) and two strip-type (ring and meandered PIFA) antennas embedded in muscle is presented in this paper at 2.4 GHz ISM band. It reveals that the slot types have superior performance in terms of their radiation efficiency. Also, the radiation efficiency is improved by operating away from the resonance, mostly where the admittance is inductive. The radiation efficiency may vary over an order of magnitude or more depending on the choice of the antenna and its resonance point, a fact that deserves further attention.","PeriodicalId":341652,"journal":{"name":"2014 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128331928","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}
