The PT is adopted to drive a cold cathode fluorescent lamp (CCFL) to eliminate the downside of a conventional transformer and to reduce the dimension, particularly the thickness, of the backlight module. Next, a PLL is embedded in the backlight system, as a feedback mechanism, to track the optimal operating frequency of the PT so that the PT's temperature effect is resolved and, hence, the overall power efficiency, along with the system stability, is improved. The feedback variable proposed in this paper is a phase angle rather than a lamp current amplitude which is conventionally used. A simplified model and its design procedure are also introduced. The complete analysis and design considerations are detailed. Finally, it is encouraging to observe that the experimental results match our analytical solutions rather well.","PeriodicalId":175701,"journal":{"name":"IEEE International Conference on Mechatronics, 2005.

Defects may occur on the inside surface, outside surface, or interior of the glass. We designed and developed three sets of vision systems which can automatically inspect defects in CRT panels. The first system inspects the front-surface and two turn-segments, the second system inspects the other two turn-segments, while the third system inspects the side-wall defects. Two different kinds of lighting environments were developed to highlight the CRT panels and to simplify the image-capturing process. Meanwhile, a set of image processing methods were devised which can reliably detect the defects within the expected processing time. Experimental results demonstrate that the developed vision systems can be used to inspect CRT panels in the production line.","PeriodicalId":175701,"journal":{"name":"IEEE International Conference on Mechatronics, 2005.

Comparing with the machining, the main shortcomings of LM are the surface roughness of the work piece and time consuming. Many rapid prototyping techniques have been developed for many years, such as stereolithography apparatus (SLA), selective laser sintering (SLS) and laminated object manufacturing (LOM). The surface roughness and dimensional accuracy of the work piece still cannot conform to the requirements of the clients. The main reason is the \"step effect\" generated with layer stacking. This study develops an experimental system to achieve the layer thickness less than 25 mum which is thinner than the existing apparatuses using processes mentioned above, and the surface finish less than 8 mum. Besides, current study also investigates the feasibility of making ceramic shell mold via a new process, named ceramic laser sintering (CLS). Under the new process, the step effect can be minimized; the drying time is shortened dramatically and the production is speedy.","PeriodicalId":175701,"journal":{"name":"IEEE International Conference on Mechatronics, 2005.

Some researchers have been focusing on the RP applications for functional part fabrication in recent years. One of the most challenge research topics in RP is the heterogeneous object fabrication, particularly in the graded material objects. The graded material means the material composition is changed according to the area of the object. The graded material object model includes the typical part geometric information and the heterogeneous material information that forms a more complicated object model. This research developed a heterogeneous object model and implemented on a software program. The result shows that the heterogeneous model contains material grading information as well as geometry information. Two demonstrated examples are illustrated for the material composition distribution in the end of this paper.","PeriodicalId":175701,"journal":{"name":"IEEE International Conference on Mechatronics, 2005.

Gray code patterns are projected onto the object surface by a DMD projection device and a CCD camera captures the distorted pattern images. For the purpose of precision measurement, a 3D mathematical model is proposed for the system and a calibration process is developed to obtain system parameters. The surface profile can be computed based on the calibrated model. In order to acquire higher measurement resolution, we propose a correspondence matching method which combines Gray codes encoding and sub-pixel edge detection. With a line-shifting procedure, the measurement resolution is elevated four times higher. Furthermore, an uncertainty analysis is performed to evaluate the performance of the developed system. Experiment results demonstrate the system has measurement area of 12 times 9 mm2 with lateral resolution about 10mum and vertical resolution about 3mum.","PeriodicalId":175701,"journal":{"name":"IEEE International Conference on Mechatronics, 2005.

In this paper, the design of a uni-polar controllable intensity of magnetic field supply unit is described and implemented to improve the adjusting capability of magnetic field, H, for generating the related effect of magnetic field that is applied and the removal in MR to cool down systems. The proposed magnetic field supply unit, taking the coils as loading, is composed of a full-bridge PWM control inverter circuit, a coupling transformer, and a rectifier; thereby the controllable DC current can be outputted to regulate the total magnetic field by the produced H based on the magnetic core with wound coils. Simulation results demonstrate the feasibility of the presented structure, and the experimental results show the effectiveness of the controllable H ranges from 0.667 Tesla to 1.07 Tesla as well.","PeriodicalId":175701,"journal":{"name":"IEEE International Conference on Mechatronics, 2005.
