為解決傳統(tǒng)可視倒車雷達視頻字符疊加器結(jié)構(gòu)復(fù)雜，可靠性差，成本高昂等問題，在可視倒車雷達設(shè)計中采用視頻字符發(fā)生器芯片MAX7456。該芯片集成了所有用于產(chǎn)生用戶定義OSD，并將其插入視頻信號中所需的全部功能，僅需少量的外圍阻容元件即可正常工作。給出了以MAX7456為核心的可視倒車雷達的軟、硬件實現(xiàn)方案及設(shè)計實例。該方案具有電路結(jié)構(gòu)簡單、價格低廉、符合人體視覺習(xí)慣的特點。經(jīng)實際裝車測試，按該方案設(shè)計的可視倒車雷達視場清晰、提示字符醒目、工作可靠，可有效降低駕駛員倒車時的工作強度、減少倒車事故的發(fā)生。 Abstract: A new video and text generation chip，MAX7456，was used in the design of video parking sensor in order to simplify system structure，improve reliability and reduce cost. This chip included all the necessary functions to generate user-defined OSDs and to add them into the video signals. It could be put into work with addition of just a small number of resistances and capacitors. This paper provided software and hardware implementation solutions and design example based on the chip. The system had the characteristics of simplicity in circuit structure，lower cost，and comfort for the nature of human vision. Loading Road test demonstrates high video and text display quality and reliable performance，which makes the driver easy to see backward and reduces chance of accidents.

vxworks下的GIS系統(tǒng)。 使用說明： 1.下載 "VxEmapgis.out" 或則 "VxEmapgis2.out" 到目標機 2.運行 "main" ，啟動應(yīng)用程序 , 3.按 "ESC" 彈出菜單， 4.選擇 "打開圖層" ， 彈出圖打開窗口 ， 輸入圖層文件名稱 如 “Road.vxw” 或者 “water.vxw” 5.按 大寫字母"O"，確定， 或者大寫字母 “C”取消 6.按方向箭頭、pagedown , pageup 實現(xiàn)漫游 ， , + , - 實現(xiàn)縮放 7.按 "ESC" 第二次可以取消菜單 8.圖層控制窗口中,列出了已打開的圖層 , 使用方向箭頭移動,選擇相應(yīng)的圖層可以關(guān)閉,也可以在這里打開圖層 9.選擇菜單項 退出系統(tǒng) ，結(jié)束應(yīng)用程序 注：需要支持x86-bios 的PC機 ， 我測試所用機器是: 目標機: p2的350M cpu + 256M內(nèi)存 + Tornado2.02 + windml2.0 主機: p4 + window2000 server 雖然我已經(jīng)把windml的庫連接到程序里，可能還需要安裝WINDML2.0,我不大確定. 需要把圖層文件（“Road.vxw” , “water.vxw” , "region.vxw" , "placename.vxw"）,符號文件(symbollib目錄)等 拷貝到wftpd的根目錄下面 VxEmapgis.out : 沒有中斷提示 VxEmapgis2.out: 有中斷提示

It’s your first day in the lab.Undoubtedly you are experiencing a range of emotions: excitement, curiosity, anxiety. You will be working in this lab and with a group of people, as well as with your supervisor, for several years to come. This is the first day of a long commitment and, for some, a hard Road ahead. Which is why it’s important to get off on the right foot.

Much of Game Theory has developed within the community of Economists, starting from the book “Theory of Games and Economic behavior” by Mor- genstern and Von Neumann (1944). To a lesser extent, it has had an impact on biology (with the development of evolutionarygames) and on Road traffic Engi- neering (triggered by the concept of Wardrop equilibrium introduced already in 1952 along with the Beckmann potential approach introduced in 1956). Since 1999 game theory has had a remarkable penetration into computer sci- ence with the formation of the community of Algorithmic game theory.
