Automobiles, aircraft, marine vehicles, uninterruptiblepower supplies and telecom hardware represent areasutilizing series connected battery stacks. These stacksof individual cells may contain many units, reaching potentialsof hundreds of volts. In such systems it is oftendesirable to accurately determine each individual cell’svoltage. Obtaining this information in the presence of thehigh “common mode” voltage generated by the batterystack is more diffi cult than might be supposed.

SL811開發資料_包含源程序_電路圖_芯片資料:SL811HS Embedded USB Host/Slave Controller.The SL811HS is an Embedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB peripherals. The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers.The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUs and many others. Internally,the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.

基本的編輯工具(GENERAL EDITING FACILITIES) 對象放置(Object Placement) ISIS支持多種類型的對象，每一類型對象的具體作用和功能將在下一章給出。雖然類型不同，但放置對象的基本步驟都是一樣的。 放置對象的步驟如下(To place an object:) 1.根據對象的類別在工具箱選擇相應模式的圖標(mode icon)。 2. Select the sub-mode icon for the specific type of object. 2、根據對象的具體類型選擇子模式圖標(sub-mode icon)。 3、如果對象類型是元件、端點、管腳、圖形、符號或標記，從選擇器里(selector)選擇你想要的對象的名字。對于元件、端點、管腳和符號，可能首先需要從庫中調出。 4、如果對象是有方向的，將會在預覽窗口顯示出來，你可以通過點擊旋轉和鏡象圖標來調整對象的朝向。 5、最后，指向編輯窗口并點擊鼠標左鍵放置對象。對于不同的對象，確切的步驟可能略有不同，但你會發現和其它的圖形編輯軟件是類似的，而且很直觀。 選中對象(Tagging an Object) 用鼠標指向對象并點擊右鍵可以選中該對象。該操作選中對象并使其高亮顯示，然后可以進行編輯。

This program will ask how many numbers you want to find the average of, then it will allow you to enter your numbers(yes they can even be decimals) then it will calculate the mean, median, mode and range of what you enter.

This program demonstrates how to do disconnected briefcase applications with ADO. When the Connected checkbox is unchecked the application is switched into offline mode. If the application is exited at that point then the data is persisted to a file on disk (along with any edits to the data). When the application is restarted it will load the persisted data if present, otherwise it will fetch the data from the database.

通子的考試系統 本程序版權屬于通子 程序功能： 1。考生可以選擇科目進行考試 2. 考過科目不再重新登陸考試 2。考題時隨機的，避免考生之間互相抄襲。 3。考題為五題，設定30秒后自動提交 4。提交后可以直接得到你的成績，并知道你是否通過了考試了 5. 可以了解你的成績與總成績的對比 程序優缺點： 1。未使用javaBean技術。 2。使用的是聲明語句在Conn.jsp，功能是進行數據庫連接； 3。使用html處理的不好，頁面不甚美觀。 4。未采用MVC，M(mode-database)，V(view-jsp)，C（controller-servlet）. 程序流程： 進入 考生 —— 登錄界面 ——進入——測試——提交——成績 login.jsp —— test.jsp —— score.jsp test.mdb test.mdb test.mdb 抱歉： 由于時間不足,未能把java(2)班全體同學的信息全部添加到數據庫中。 附： java（2）班全體同學信息打包在里面了，有意者可以添加。 希望對此程序作改進的有我聯系。我的QQ：120244312 E-Mail：zuotongyousai@163.com
