以太網和CAN總線應用廣泛，但由于其通信協議不同，兩種總線器件間無法進行數據通信，因此，設計了基于CP2200與C8051F040的以太網總線與CAN總線接口轉換電路，并給出部分相關硬件電路與軟件設計分析。在保證數據完整和協議可靠的前提下，通過握手協議和簡化的以太網協議，不僅實現了以太網數據與CAN數據的轉發，同時還順利的解決了以太網的高速性與CAN的低速率沖突，以及兩者數據包之間的大小不同的矛盾。
Abstract: In the development of actual application， Ethernet and CAN bus are used very extensively. Owing to its various communication protocols， the communicating between two kinds of bus device can’t be carried out. Therefore， in order to solve this problem， the Ethernet-CAN bus interface circuit based on CP2200 and C8051F040 was designed in this paper， and part of the related hardware circuit and software design analysis were given. On the condition of data’s integrity and protocols’reliability， through the handshaking protocols and the Simplified the Ethernet protocol， not only the data switching between CAN and Ethernet was realized， but also the differ in velocity and packet size was solved.
基于PIC單片機的低功耗讀卡器硬件設計:本文提出了一個完整的基于串口的智能讀卡器子系統設計方案并將其實現。讀卡器的設計突出了小型化的要求，全部器件使用貼片封裝。為了減小讀卡器的體積，設計中還使用了串口竊電的技術，使用串口信號線直接給讀卡器供電。為此，讀卡器使用了省電的設計，采用了省電的集成電路，并大膽簡化了許多傳統的設計電路。關鍵字： 讀卡器， 單片機， 串口竊電
Abstract： This paper aims to put forward a complete design of Smart IC card reader based onSerial Port and propose the way of realizing it for the purpose of Network Security. SMD isadopted to make Smart IC reader smaller in this design. To reduce the volume of Smart ICreader， Serial Port powered technology is employed to get power from the signal line of Serial Port. For this reason， low-power consumption components are adopted in the design and some traditional designs are Simplified to reduce the power consumption.Keywords： Card Reader； Single-chip Computer； Serial Port Powered
IC 卡系統保存了加密算法所需要的工作密鑰，供加密算法對網絡上傳輸的數據加密使用，是整個系統網絡安全的核心。在IC 卡子系統中，讀卡器是一個重要的部分。它起著管理IC卡、在IC 卡和PC或網絡計算機間傳遞數據的重要作用。本文以一片PIC單片機為核心完成了基于RS232 串口的讀卡器的硬件設計。
TOYFDTD1 is a stripped-down minimalist, 3D FDTD code demonstrating the basic tasks in implementing a simple 3D FDTD simulation. An idealized rectangular waveguide is modeled by treating the interior of the mesh as free space and enforcing PEC conditions on the faces of the mesh. A Simplified plane wave source is inserted at one end. First released 12 April 1999. Version 1.03 released 2 December 1999.

This paper presents an interactive technique that
produces static hairstyles by generating individual hair strands
of the desired shape and color, subject to the presence of gravity
and collisions. A variety of hairstyles can be generated by
adjusting the wisp parameters, while the deformation is solved
efficiently, accounting for the effects of gravity and collisions.
Wisps are generated employing statistical approaches. As for
hair deformation, we propose a method which is based on
physical simulation concepts but is Simplified to efficiently
solve the static shape of hair. On top of the statistical wisp
model and the deformation solver, a constraint-based styler
is proposed to model artificial features that oppose the natural
flow of hair under gravity and hair elasticity, such as a hairpin.
Our technique spans a wider range of human hairstyles than
previously proposed methods, and the styles generated by this
technique are fairly realistic.
