This paper proposed a method of generating two attractors in a novel grid multi-scroll chaotic system.Based on a newly generated three-dimensional system,a two-attractor grid multi-scroll attractor system can be generated by adding two triangular waves and a sign function.Some basic dynamical properties,such as equilibrium points,bifurcations,and phase diagrams,were studied.Furthermore,the system was experimentally confirmed by an electronic circuit.The circuit simulation results and numerical simulation results verified the feasibility of this method. 相似文献

为解决在Windows CE系统启动过程中的黑屏现象,提出了一种基于Windows CE 6.0下Bootloader中添加启动画面的设计方法,避免在系统启动时间内显示屏幕上无画面输出,减小了在实际产品启动过程中的时延造成客户的视觉等待而降低客户体验的问题.该方法是在Bootloader中LCD控制器初始化后加入一段完整启动输出画面的代码,同时,利用线性插值法对图像进行优化处理.与传统的启动画面的实现相比较,在保证图像清晰的同时,该设计方法降低了对图片大小的限制,实验结果表明,线性插值算法对于缩放比例较小的情况是完全可以接受的. 相似文献

手机侧背光照明导光板设计模拟 总被引:1,自引:0,他引:1
为了提高手机侧背光照明导光板的亮度及亮度均匀性,对上表面为41 mm×26 mm的楔形导光板进行了模拟仿真,并对导光板底面不同的印刷式散射网点排布、不同的楔形导光板底面角度及不同的球缺形凸包网点排布进行了研究。结果显示,导光板底面排布印刷式散射网点时,导光板上表面亮度分布的均匀性较差,而出射光通量的百分比小于26%;当导光板底面排布球缺形凸包网点时,导光板上表面亮度分布的均匀性得到提高,出射光通量的百分比提高10%。楔形导光板底面角度81°时的出光效果优于85°时的效果。 相似文献
