Examples are the practice support systems used in activities such as sport and dance, for instance, the system employed in baseball pitching form analysis. This analysis evaluates the state of the throwing form numerically and visually by measuring the velocity and trajectory of the hand. This requires measurement of the hand by a sensor and is accomplished by using a motion capture system as the method for measuring hand motion with high accuracy. However, it is time consuming to prepare the system. Therefore, a 3D range image sensor, which is inexpensive and easy to prepare, is proposed. However, as the actual measurement accuracy of this sensor is unknown, it was evaluated by calculating the error with the measured value of motion capture as the true value. In this research, we calculated the error between the 3D coordinates and velocity to evaluate the error. As a result, the effectiveness of the measurement accuracy of the hand motion by the 3D range image sensor was confirmed. The results suggest that the 3D range image sensor can be used in various situations involving human activity.","PeriodicalId":289209,"journal":{"name":"2017 Eleventh International Conference on Sensing Technology (ICST)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124113990","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}

This paper highlights the importance of media/buffers with different pH values when used for developing nanostructure based biomarkers. Very recently ZnS nanowires and ZnS coated CdSe quantum dots are being employed as selective biomarkers. The optical properties of ZnS-NW and CdSe/ZnS QDs strongly depend on the pH of the media. The work is then extended to the photoluminescence spectroscopy of water soluble CdSe/ZnS core/shell quantum dots in a varied pH of the phosphate buffer saline (PBS) media. Photoluminescence spectroscopy (PL) of mercaptoacetic acid (MAA) and a cardiac antibody (digoxin) conjugated ZnS-NW showed strong dependence of PL intensity on the pH of the media. It demonstrated that the pH and the pKa value of used thiol molecule were critically linked with each other. Similarly, the photoluminescence spectroscopy of the water-soluble CdSe/ZnS dots at varied pH (4 to 14) showed a strong dependence on the pH. The QD emission was found stable when the pH of the solution was close to 7. However, a strong decrease in luminescence intensity was observed in strong acidic and basic conditions, which was attributed to the presence of Lewis acid: protons (H+) and sodium ions (Na+) and Lewis bases: thiolate (S−) and oxygen ions (O−). At high ionic strength there is agglomeration of quantum dots was due to the formation of sodium salt bridge (COONaOOC) complex along with spectral red shift. The current study suggested the best use of water soluble QDs was at pH 7 to 10 for PBS buffer in different biological environments.","PeriodicalId":289209,"journal":{"name":"2017 Eleventh International Conference on Sensing Technology (ICST)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130236250","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 signal transmission through a hazardous region in the form of optical signal is preferred more than the electrical signal. In the present work, an experimental study has been made with low cost modified optically isolated Rotameter based flow transmitter and flow control system. This flow indicating controller has been designed using modified LVDT based Rotameter, PC based controller NI DAQ and LabVIEW software. An analog signal-conditioning and flow control circuit is developed. The same was calibrated with flow measuring test rig with a standard available industrial flow meter. The output of the opto-isolator circuit has been shown in a PC and the flow rate is controlled to a desired value using LabVIEW software. The output of the Rotameter is sent to the remote location through optical fiber cable and converted to electrical signal using optoelectronics converter. The experiment has been performed and results are presented in the paper. The experimental result follows the theoretical equations. Simulation is done on optical flow transmitter. It has been observed that variation of LVDT output voltage and the characteristic of the transducer and PC based controller are all linear in nature.","PeriodicalId":289209,"journal":{"name":"2017 Eleventh International Conference on Sensing Technology (ICST)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123120754","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}

Current transducer that is formed using Hall-Effect sensing elements arranged in the form of a circular array, around the current carrying conductor, has been reported in the literature. This scheme has many benefits as no magnetic core is used, but the accuracy of the system depends on various factors, including the positioning of the conductor at the center of the circular array and positioning of the individual Hall sensing elements. Positioning includes the alignment of the axis of sensitivity of the Hall sensor to the tangential component of the field and the position of the sensor in the predefined circle. When the sensor unit is made, there will be misalignments for each Hall sensor from its predefined position and direction of sensitivity. In addition, any deviation of the sensors array from the circular shape, say an oval shape, will introduce errors. Also, the normal of the plane of circular array should be parallel to the axis of the conductor. This may not be the case in practice. In order to analyze the effect of the above mentioned parameters and to quantify the error due to each in the final output, a suitable prototype of the Hall Effect current transducer has been developed and the above listed parameters have been tested in the laboratory, one by one. Along with the experimental studies, ANSYS Maxwell tool has been used for conducting the Finite Element Method (FEM) analysis and to support the experimental observations. This study will help the sensor designer to get detailed insights into the effect of various misalignments in the output.","PeriodicalId":289209,"journal":{"name":"2017 Eleventh International Conference on Sensing Technology (ICST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123131191","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}

Ensuring optimal levels in line with the volume and intensity of exercise is essential. Carbohydrate manipulation is a well thought out and rigorous component of any athlete's regime and ensures elite levels of performance and the correct training adaptations can be obtained. Glycogen from oyster mixed into a water solution was used to manipulate concentrations observed in healthy human subjects ranging from 0–400mmol/L. The electromagnetic sensor used in this study swept frequencies between 10MHz and 4GHz, allowing an ideal range to locate any possible frequencies that match glycogens electromagnetic footprint. Data produced from the scattering parameter S11 identified a strong linear correlation between glycogen (mmol/L) and S11 (dBm), r = 0.9, p = < 0.002, with a R2 = 0.87 at 2.11 GHz. This paper provides the first significant data that an electromagnetic sensor can successfully monitor change in glycogen concentration. This provides an encouraging basis for future work to create practical non-invasive method for in-vivo detection and quantification of glycogen in human skeletal muscle. The progression of this research will be to analyse the sensor during different glycogen depletion exercise trials in human subjects.","PeriodicalId":289209,"journal":{"name":"2017 Eleventh International Conference on Sensing Technology (ICST)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126475601","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}

Zinc is a metal, which when present in water in high concentrations, could cause adverse health effect with long-term exposure. Metal ion dispersion from abandoned mines is a global concern and one of the principle cause of metal pollution in water. Consequently, it is necessary to develop and deploy new sensing systems able to monitor continuously the water quality. In this work, the feasibility of using eight-pair interdigitated (IDE) sensors coated with bismuth oxide based film for continuous monitoring of zinc in water is assessed with microwave and electric techniques. The reaction between zinc in the concentration range 0–100 mg/l in deionised water and bismuth oxide based thick film screen-printed on planar IDE sensors starts after 30 seconds and the adsorption equilibrium was attained within 10 minutes; the response is faster during the initial stage and slows as equilibrium is reached. Furthermore, results show good linear correlations between C (capacitance) and S11 (reflected power) and zinc concentration, respectively about R2=0.99 and R2=0.97 at 5 and 10 minutes. In addition, the recovery time of sensors is evaluated to be 100–150 sec demonstrating the sensor reusability and potential for a continuous monitoring.","PeriodicalId":289209,"journal":{"name":"2017 Eleventh International Conference on Sensing Technology (ICST)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131556883","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}
