恒流驱动和提 高LED的光学效率是LED 应用设计的两个关键问题，本文首先介绍大功率LED的应用及其恒流驱动方案的选择指南，然后以美国国家半导体(NS)的产品为例，重点讨论如何巧妙应用 LED恒流驱动电路的采样电阻提高大功率LED的效率，并给出大功率LED驱动器设计与散热设计的注意事项。-LED constant current drive and to improve the optical efficiency of LED application design of two key issues, this paper describes the application of high-power LED constant current driver and the choice of the program guide, and then the United States National Semiconductor (NS) products, for example, focus on how skillful application of LED constant current driver circuit of the sampling resistor to improve the efficiency of high-power LED, and gives high-power LED driver design and thermal design considerations.

机动目标的跟踪问题一直是人们研究的重点，实现机动目标精确跟踪，首要解决的问题就是使所建立的目标运动模型与实际的目标运动模型匹配。目前常用的有多模型(MM)，交互式多模型(IMM)，切换模型等。多模型方法就是对一组具有不同机动模型分别进行Kalman滤波，最终的参数估计是各滤波器估计值的加权和；在多模型基础上，Shalom提出了交互式多模型方法，这一方法对无序目标的机动检测，显示了更好的鲁棒性和跟踪的稳定性；切换模型则是分别建立机动和非机动运动模型，利用机动检测实现在这两个模型之间的切换。一般来说，交互式多模型的跟踪性能较好。-mobile target tracking problem has been a focus of research and achieve precise maneuvering target tracking, the most pressing issue is to enable the establishment of the target model and the actual movement of the target model matching. At present, more commonly used model (MM), interactive multi-model (IMM), switching model. Multi-model approach is a group of different mobile models were Kalman filtering, The final parameter is the estimated value of the filter is estimated weighted; in the multi-model basis, Shalom made the interactive multi-model approach that the objectives of the motor disorder detection, better show the robustness and stability of the track; switching model is set up motorized and non-motorized sports
