The current method was applied to the laparoscope video at the rate of up to 5 frames per second to visualize its stereo video. Correlation coefficients between the depth maps calculated with our method with those from the shape from shading algorithm were within the range of 0.70 to 0.95 (P <; 0.05).","PeriodicalId":265886,"journal":{"name":"2014 IEEE International Symposium on Bioelectronics and Bioinformatics (IEEE ISBB 2014)","volume":"36 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121163751","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}

Dementia wandering is a subject of study and research in the field of gerontology for more than 3 decades. The topic has then drawn the attention of technologists and particularly computer scientists since early 2000. Though a number of solutions and applications have been proposed and implemented to manage wandering, not many are widely used in practice due to 2 reasons. First, technologists' understanding and perception of wandering do not align with those of gerontologists. This consequently lowers the chance of proposed solutions to be accepted for clinical applications. Second, most solutions do not address all the dimensions of dementia wandering. Few applications cater the needs of other stakeholders involved including caregivers, physicians and researchers. This paper aims to bridge the knowledge gaps between gerontologists and technologists. We first present a conceptual map of wandering science from the perspectives of gerontologists. Then we provide a framework which identifies main threads of technologies that can be further developed to manage dementia wandering. We hope that the conceptual map and technological framework will guide technologists in developing relevant and essential assistive solutions which are not only widely used in clinical practice but also address the needs of all the parties involved.","PeriodicalId":265886,"journal":{"name":"2014 IEEE International Symposium on Bioelectronics and Bioinformatics (IEEE ISBB 2014)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127479706","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 system includes a graphical user interface, which allows real-time graphing of the force measurements and keeps a database for offline comparative data analysis by the therapist. It employs a wireless connection between the microcontroller and the computer using Bluetooth technology, which increases mobility of the patient.

In order to calculate SpO2, accurate amplitude of PPG is essential. As a matter of fact that the PPG signal is acquired through an optical sensor, it is prone to be affected by motion artifact. As a result, noise cancellation is a major issue in the calculation of SpO2. In the calculation of SpO2, the exact waveform is not the key point, whereas the amplitude plays the important role. Therefore, Fourier analysis is adopted to perform the noise cancellation. In the proposed system, data acquisition and analog filtering are done on a printed circuit board which is controlled by an FPGA. The acquired data are sent to a computer, where Fourier analysis is done to cancel motion artifact. Experiments have been done to demonstrate the performance of the proposed algorithm.

We decomposed a number of intrinsic mode functions, the instantaneous spectrum and the Hilbert energy spectrum and compared the differences between spike and non-spike waves. The analysis results showed that the ratios of the normal wave to the referred total energy for IMF1, IMF2, and the residual function exceeded 10%.
