In this paper, we propose a biased Kalman filter (KF) by biasing the minimum-variance unbiased (MVU) output of a traditional KF. The theoretical results show that the proposed biased KF (BKF) provides a tradeoff between the estimation bias and variance, leading to reduce the estimation MSE of the traditional KF. For different applications, two different bias methods, called as the optimal bias and blind bias method respectively, are proposed. Both the analytical and simulated results show that the presented BKF can outperform the traditional KF in terms of MSE.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115125931","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 powders of different compositions were heated at 1000 °C for 12 hrs. The copper chloride transforms into copper oxide upon heating. These films of different compositions were fired at 550 °C for 30 min. The electrical, structural and morphological properties of the films were investigated. The X-ray diffraction analysis of pure and loaded films shows the polycrystalline nature. The surface morphology of the films was studied by SEM. The final composition of each film was determined by EDAX analysis. The gas response, selectivity, response and recovery time of the sensor were measured and presented. The sensing performance was tested for various gases at different operating temperatures. The ZnO sensor loaded with 5 At. wt. % of CuO is found to be high gas response to LPG gas than pure ZnO and other loading concentrations with fast response and recovery time.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116098869","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 presented optical measurement unit consists of a CO2 sensitive layer mounted onto the end of sensing probe and an optoelectronic interrogation unit in order to convert the measurement signal into detectable signal. The measurement technique is the phase modulation fluorometry using Resonance Energy Transfer (RET) as sensing scheme. RET measurements were made by incorporation of ruthenium-(II)-tis-4,7-diphenyl-1,10-phennathroline (Rudpp)32- together with pH indicator ion-paired with tetraoctylammonium (TOA-OH) as the cunterion in a highly gas-permeable matrix. As a protective coating a high gas permeable Teflon with added graphite particles was used to eliminate interferences by ionic species. The performance of the whole sensor system is presented with respect to spectral characteristics, dynamic range (0 – 60 mg/l of dissolved CO2), required sensor system specifications, temperature behavior and long term stability. First field tests performed in real fish farming conditions are presented as well.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131734701","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}

In this paper, authors describe a sensor network built using PSoC (Programmable System-on-Chip) from Cypress Semiconductor. The advantage of PSoC is that it integrates analog, digital and controller components (all required to process sensor data) on a single chip, thus resulting in a smaller footprint for sensor nodes. Communication with other nodes is achieved through CyFi low power RF module operating in the 2.4GHz ISM band. Operation of the network has been tested by implementing the SPIN (Sensor Protocol for Information via Negotiation), a well-known data-centric protocol for sensor networks.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124873118","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 new high-speed composite flywheels are highly stressed on the rotor side and therefore require condition monitoring for a save and reliable operation. This paper presents a monitoring approach based on modal analysis. A cylindrical test object, representing the simplification of an external flywheel rotor, is analyzed. A numerical simulation of the test object is performed using Comsol Multiphysics software, and practical measurements are carried out to verify the basic assumptions underlying the proposed measurement approach. Simulation and experimental results are used to assess the applicability of the approach for condition monitoring of flywheel rotors.

Such a training system, where the position and angle of insertion of the needle used to administer anesthesia are determined employing a capacitive sensor array with suitable signal conditioning and sensing logic is described in this paper. Simulation studies and test results on a prototype built and tested demonstrated the practicality of the proposed scheme.

Existing robotic systems are still very far from humans in terms of their manipulation skills. This fact can be partly accounted for by a lack of integrated multimodal approaches to the problem. We present our research on the combination of vision, tactile and force sensing for manipulation with robotic hands, as part of our FPI approach the Framework for Physical Interaction, in which a grasp and a task are concurrently planned. A visual servoing loop is used to control the hand for task execution, which we combine with a tactile control signal, as well as an impedance force controller. The task can be performed even if a sensor is not available or provides inaccurate data. A number of experiments are reported for comparing the results of the integrated trimodal controller. Results show that it outperforms the bimodal or single-sensor approaches.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130179550","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 base station transceiver (BTS) is carried on an aerial vehicle to relay mobile users to ground base station. The Sky-Net System is designed for a temporary communication environment for emergency and disaster rescue in remote areas. An eCell BTS is selected for microwave downlink which requires high precision line-of-sight (LOS) antenna alignment. Two directional antennas for horizontal and vertical polarization are installed on airborne to track the ground receiver. To overcome the dynamic flight characteristics, a real time servo control system is developed on a microcontroller-based on GPS and AHRS feedbacks to accomplish high accuracy requirement for 5.8GHz microwave system. The UAV and ground station are exchanging their 10Hz GPS data and linking via 900MHz and 5.8GHz wireless modules for higher reliability. By reading the difference of attitude and position data, the ground antenna is tracking the UAV through the servo control system. The airborne unit reads AHRS and ground GPS data to control the tracking servo mechanism to align the airborne antenna onto ground antenna. The Euler's angles GPS and flight data are read to determine an appropriate angle for antenna alignment to ground antenna. The antenna tracking system is completed as the preliminary technology for further Sky-Net Project in real flight verifications with very stable antenna alignment for LOS microwave transmission.","PeriodicalId":202062,"journal":{"name":"2011 Fifth International Conference on Sensing Technology","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121736499","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}
