Practical application shows that the system is reliable designed the slip motor speed control system for packing rubber strip which is used in plastic steel door and window. The system stable and higher precision of control. The system design provides reference for similar control system and builds the basis for the design of intelligent control system. 2010 IEEE. 32-bit embedded microprocessor LPC2136 as the control core PWM speed control velocity feedback from tachogenerator rubber strip position feedback from the CMOS camera has proved that CMOS camera's image quality meets the engineering requirement
	Remote sensing image restoration using estimated point spread function (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Information, Networking and Automation, ICINA 2010, October 17, 2010 - October 19, 2010, Kunming, China 作者: Yang L.; Yang L. 收藏 \| 浏览/下载：32/0 \| 提交时间：2013/03/25 In order to reduce image blur caused by the degradation phenomenon in the imaging process the acquired images of the space remote sensing camera are restored. First the frequency-domain notch filter is adopted to remove strip noises in the images. Then degradation function which is referred to as the point spread function (PSF) of the imaging system is estimated using the knife-edge method. To improve the accuracy of the estimation the estimated PSF is adjusted with Gaussian fitting. Finally the images are restored by Wiener filtering with the fitted PSF. The restoration results of the remote sensing images show that almost all strip noises are eliminated by the notch filter. After denoising and restoration the variance of the remote sensing image worked with in this paper increases 30.979 and the gray mean gradient increases 3.312. Due to Gaussian fitting the accuracy of the PSF estimation is heightened. Image restoration with the final PSF is benefit to interpreting and analyzing the remote sensing images. After restoration the contrasts of the restored images are increased and the visual effects become clearer. 2010 IEEE.
	Micro-motion exposure method based on PZT piezoelectric ceramics (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photoelectronic Detection and Imaging 2009: Material and Device Technology for Sensors, June 17, 2009 - June 19, 2009, Beijing, China 作者: Meng Z.; Meng Z. 收藏 \| 浏览/下载：102/0 \| 提交时间：2013/03/25 There mainly is laser digital photofinishing technique and digital photofinishing technique based on LCD consisting of TFT and LCOS in the digital photofinishing field at the present time. The former have a good many merit such as wide color gamut high processing rate large output size and high brightness but his cost is very high his maintain technique being comparatively complex that result in difficult use for people. The utilization ratio of the latter is low because of lower resolution and lower aperture ratio for LCD but the digital photofinishing based on LCD have lower cost and higher utilization ration being suitable for people's current standard of living. Considering above mentioned problem a micro-motion exposure method based on PZT piezoelectric ceramics used in digital image photofinishing is presented. The two-dimension micro-motion exposure system consisting of PZT piezoelectric ceramics LCD panel polarizing film and spring strip is designed. By means of PZT piezoelectric ceramics the LCD panel is removed about the one half of the pixel size of the LCD panel for four times from the original place at the same time imaging system is exposed four times at the printing paper. The software is used to control the time synchronization the exposure time and motion range of the LCD panel. The system has advantages such as shorter response time than 0.1seconds lesser motion error than 0.01 microns high stability and repeatability. Experimental results show that the proposed micro-motion exposure method improve the picture brightness and enlarge output size at the meantime reducing the cost of the system. 2009 SPIE.
	A novel method for fabrication of integrated shadow mask for patterning electrode in passive matrix OLED displays (EI CONFERENCE) 会议论文 OAI收割 6th Electronics Packaging Technology Conference, EPTC 2004, December 8, 2005 - December 10, 2005, Singapore, Singapore Huang Z. H.; Su W. M.; Qi G. J.; Lu H. J.; Zeng X. T.; Wong S. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 This paper reports a novel method for making an integrated shadow mask used in fabrication of passive matrix OLED displays. Common positive and negative photoresists were employed to produce retrograded strip pillars with large overhang and undercut by photolithography. The pillar strips serve as an effective shadow mask for patterning the organic layers and the metal cathodes in OLED display devices. It is expected that this method can significantly enhance the performance of passive matrix OLED at a low shadow mask fabrication cost. The method can be used for fabricating more complicated structures for other display applications. 2004 IEEE.
