However, sometimes these sensors need to be located in areas where wiring is not possible, such as in application of implanted biomedical devices. Some challenges that that must be overcome include the wireless power supply of sensors, accurate and steady DC reference, load-matching of circuitry, linearity of the measurements and the modulation of data. This paper investigates two types of rectification for power transfer in implanted sensor applications and the use of rectifier for phase and level modulation via Load-Shift Keying (LSK).","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132497975","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 idea of suspension is to improve the ride quality while maintaining good handling characteristics to different road disturbance. The purpose of designing the active controller for vehicle suspension systems is to decrease the traditional design between ride and handling by directly controlling the suspension forces to suit the road and driving conditions. The presented approach uses linear controller that does not require physical model of shock absorber or the car which is time consuming to derive and implement. Performance of active suspensions like robust H∞ controller, LQR controller and Fuzzy control are compared with existing passive suspension. Simulation result shows that the active controllers are better than passive in terms of settling time.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127087898","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 facial feature displacements in the video stream are used as input to a Support Vector Machine classifier. We evaluate our method in terms of recognition accuracy for a variety of interaction and classification scenarios. Our person-dependent and person-independent experiments demonstrate the effectiveness of a support vector machine and feature tracking approach to fully automatic, unobtrusive expression recognition in live video.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131616327","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 achievements notwithstanding, IGS is still tied to the traditional procedure which from the perspective of a computer engineer makes it time consuming and irresponsive to patients' needs. In this paper, a paradigm for a computational effective IGS is presented focusing on two aspects of the current IGS model which are believed to be the bottleneck for improvement viz: pre-operative planning, and inter-operative guidance.

The proposed controller design employs modern optimization tools (Particle Swarm Optimization and Differential Evolution) in a single objective constrained optimization. The objective of the optimization is to search for a set of robust controller gains such that the stability radius of the closed-loop system is maximized. The constraint of the optimization is a closed-loop poles region which is directly related to the desired time-domain control performance. The proposed controller design is applied to control of pendulum-like systems (gantry crane, flexible joint and inverted pendulum). The results show the robust performance of the designed controller.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129204648","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 several closed loop power control algorithms are analyzed considering loop delay to cope with random changes of the radio channel and interference. Adaptive algorithms are considered that utilize ideas from self-tuning control systems. The inherent loop delay associated with closed loop power control can be included in the design process. Another problem in closed-loop power control is that extensive control signaling consumes radio resources, and thus the control feedback bandwidth must be limited. To enhance the performance of closed-loop power control in limited-feedback-case is investigated. The performances of the adaptive algorithms are investigated through both analysis and computer simulations, and compared with well-known algorithms from the literature. After proper investigation and analysis it is anticipated that significant performance improvements are achievable with the adaptive algorithms.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126825624","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 uses a web camera as a vision sensor, PC sound cards as output signal controllers, and two DC motors as a pan-tilt driver mechanism. The sound card is expected to produce a higher output signal in a PWM form to drive the motors. The motors will react accordingly when they receive the signals to ensure that the camera always focuses on the centroid of the light source. The system used image processing technique to detect and determine the location of the light source and was programmed to send PWM through the sound card to drive the motors to correct the error produced from the light movement. In MATLAB programming environment, a closed-loop control is implemented to provide interaction between camera and sound cards as devices to control the motors to track the light source. The system has been designed and tested with various locations of light source. The data which were obtained by experiments indicate the ability of the proposed controller.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115312434","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}

Many consideration need to be taken care while designing and controlling robotic arm. In addition, different robotic arm design may lead to different control solution. Furthermore, it is difficult for the robotic arm to follow the assigned geometry path in high precision and accuracy manner. This paper introduces the design and development of 6-DOF (degree of freedom) PC-Based Robotic Arm (PC-ROBOARM). The main context of the study is concerning a 6-DOF robotic arm, which is modeled as three-link, with each joint connected with a suitable servomotor. The robotic arm design and control solution is implemented by self developed computer software which is named as SMART ARM. It is a computer aided design and control solution for 6-DOF robotic arm which come with an user friendly graphical user interface (GUI). It allows user to model or design virtual robotic arm before building the real one. Therefore, the user can estimate the optimum size of actual robotic arm at the beginning so as to minimize the building cost and suite the practical environment. Furthermore, once the actual robotic arm has been built, the user can reuse the software to control the actual robotic arm in an effortless way without wasting time in constructing new control solution. The software also provides simulation feature. Through simulation in the GUI, the software assists greatly in visualizing the robotic arm trajectory planning. The PC-ROBOARM is actual robotic arm developed to prove the simulation results. The 6-DOF robotic arm design is based on PUMA (Programmable Universal Machine for Assembly) jointed-arm model. Both point-to-point motion and continuous path motion are tested in simulation and actual arm controls.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133482147","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}
