The sensor is equipped with a high-birefringent photonic crystal fiber (HB-PCF) as sensing unit and used to measure the pressure in gaseous and liquid media. The linear polarized light injects into HB-PCF with 45° angle at the slow axis and the output light is separated into two perpendicular polarized light with 0° and 90°. Then one of them is rotated 90°, which combine with the other to form light interferometer. Pressure load affects the birefringence of HB-PCF, leading to the variety of output light intensity. The analysis result shows that the centripetal pressure increases the effective refractive index of polarization model in both fast and slow axes with a linear relationship of 8.97×10-6 RIU/MPa and 6.48×10-6 RIU/MPa respectively, so that tends to counteract the birefringence of the HB-PCF caused by its asymmetric structure, with a linear relationship of 2.49×10-6 RIU/MPa. Consequently, the pressure vary from 0 to 100 MPa can be inferred by the output light visibility. The proposed sensor has many advantages such as small volume, simple structure, strong environmental, and tolerance, etc. It can be widely used in pressure measurement and structure health monitoring.","PeriodicalId":297617,"journal":{"name":"2016 10th International Conference on Sensing Technology (ICST)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132240177","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}

Head-mounted eye-tracking equipment has a wide range of application because of its flexibility and high gaze estimation accuracy. But the user's head should keep still using a chin rest or other tools, or will lead to enormous gaze estimation errors. In this paper, a head rotation compensation method is proposed for head-mounted eye-tracking glasses. The whole cost of our system is 38 USD. According to our preliminary result, the mean error of gaze estimation is reduced from 8.0162° to 0.5748°, which shows that our method can compensate head rotation effectively. The data in the task based experiment reveal that our system can be used as an alternative input device to mouse.","PeriodicalId":297617,"journal":{"name":"2016 10th International Conference on Sensing Technology (ICST)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134148022","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}

Fault classification to bearing that aims to identify category of bearing fault is helpful to improve reliability and safety of bearing.

Coefficient for data representation is solved by sparse representation. Spectral clustering is performed on the coefficient to classify the samples into its category. Effectiveness of the presented method is validated by test data of bearing with different degrees of fault.

Compared with L1C/A, the length of L2C code is longer, and includes the civil moderate code (CM code, 20ms) and the civil long code (CL code, 1.5s), which are based on time division multiplexing. For the long CL code, rapid acquisition is difficult due to the large search space. To accelerate the search process and improve detection performance, a fast direct GPS L2C CL signal acquisition algorithm based on time-frequency dual folding technique is introduced in this paper. By folding both the incoming and local signals, the method can be used to significantly accelerate the acquisition speed, and the degraded code correlation properties are insignificant. The effectiveness of the method of fast direct acquisition algorithm based on the time-frequency folding technique is proven through both theoretical performance analysis and real GPS L2C signal experiments.","PeriodicalId":297617,"journal":{"name":"2016 10th International Conference on Sensing Technology (ICST)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123912351","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}

Alternatively, trust management schemes are tools to address some main issues in WSNs including memory and storage space, key generation, and re-keying. In this work, we will present solution of memory resources consumption and key management processing issues for a secure maritime coastal monitoring system.
