The Philips family of Multiplexers and Switches consists of bi-directional translating switches controlled via the I2C or SMBus to fan out an upstream SCL/SDA pair to 2, 4 or 8 downstream channels of SCx/SDx pairs. The Multiplexers allow only one downstream channel to be selected at a time, while the Switches allow any individual downstream channel or combination of downstream channels to be selected, depending on the CONTENT of the programmable control register. Once one or several channels have been selected, the device acts as a wire, allowing the master on the upstream channel to send commands to devices on all the active downstream channels, and devices on the active downstream channels to communicate with each other and the master. External pull-up resistors are used to pull each individual channel up to the desired voltage level. Combined interrupt output and hardware reset input are device options that are featured.

Agilent AN 154 S-Parameter Design Application Note S參數(shù)的設計與應用
The need for new high-frequency, solid-state circuitdesign techniques has been recognized both by microwaveengineers and circuit designers. These engineersare being asked to design solid state circuitsthat will operate at higher and higher frequencies.The development of microwave transistors andAgilent Technologies’ network analysis instrumentationsystems that permit complete network characterizationin the microwave frequency rangehave greatly assisted these engineers in their work.The Agilent Microwave Division’s lab staff hasdeveloped a high frequency circuit design seminarto assist their counterparts in R&D labs throughoutthe world. This seminar has been presentedin a number of locations in the United States andEurope.From the experience gained in presenting this originalseminar, we have developed a four-part videotape, S-Parameter Design Seminar. While the technologyof high frequency circuit design is everchanging, the concepts upon which this technologyhas been built are relatively invariant.The CONTENT of the S-Parameter Design Seminar isas follows:

PhpDig is a search engine written in PHP that uses a MySQL database backend. It features indexing of both static and dynamic pages, spidering of almost all links in HTML CONTENT, in hrefs, areamaps, and frames, and full text indexing. The search results appearence is skin-able, using a very simple templates system. PhpDig是一個用PHP編寫的搜索引擎，它使用MySQL數(shù)據(jù)庫后臺。它的功能有靜態(tài)和動態(tài)頁面索引，在HTML內(nèi)容中用hrefs, areamaps，和frames以及全文本索引構(gòu)成所有的鏈接網(wǎng)。搜索結(jié)果的外觀是可定制外觀的，使用一個非常簡單的模板系統(tǒng)。

留言本 需要修改的地方都有注釋 你可以自行修改 主要有l(wèi)ogin.jsp和jdbc.java里面關系都數(shù)據(jù)庫連接部分 jdbc你修改編譯之后請放到WEB-INF\classes\wu目錄下面 數(shù)據(jù)庫采用的是mysql 建表語言是： CREATE TABLE liuyan_temp ( id int(6) NOT NULL auto_increment, url varchar(100) default # , ip varchar(20) default NULL, email varchar(50) default # , qq varchar(20) default NULL, sj varchar(30) default NULL, CONTENT text, xm varchar(20) default 沒有姓名 , KEY id (id) ) TYPE=MyISAM

In this book, we aim to give you an introduction to a wide variety of topics important to you as a developer using UNIX. The word Beginning in the title refers more to the CONTENT than to your skill level. We ve structured the book to help you learn more about what UNIX has to offer, however much experience you have already. UNIX programming is a large field and we aim to cover enough about a wide range of topics to give you a good beginning in each subject.

The extraordinary growth of the World Wide Web has been fueled by the ability it gives authors to easily and cheaply distribute electronic documents to an international audience. As Web documents have become larger and more complex, however, Web CONTENT providers have begun to experience the limitations of a medium that does not provide the extensibility, structure, and data checking needed for large-scale commercial publishing. The ability of Java applets to embed powerful data manipulation capabilities in Web clients makes even clearer the limitations of current methods for the transmittal of document data.

本書包含了許多Ajax技術(shù)的設計模式。例如：你應該如何分割數(shù)據(jù)以便于分配呢？答案是，采用內(nèi)容分塊模式（CONTENT Chunking Pattern）；如何有效地維護狀態(tài)或至少是維護痕跡呢？答案是，采用持久通信模式（Persistent Communications Pattern）；如何讓用戶對所有潛在的數(shù)據(jù)了如指掌呢？答案是，采用無限數(shù)據(jù)模式（Infinite Data Pattern）。通過書中呈現(xiàn)的九種模式，作者幾乎發(fā)掘了所有的Ajax理論，這些知識對你將來編寫應用程序時制定策略有重大的幫助。每種模式都有相應的章節(jié)對其進行論述，每章均以模式的設計意圖為開頭，然后介紹使用該模式的動機，并列舉一系列使用該模式開發(fā)的應用程序和與該模式相關聯(lián)的設計模式。接著，以解決實際問題的方式詮釋該設計模式的架構(gòu)。最后，執(zhí)行程序通過代碼及用戶與各種網(wǎng)頁的互動形式展現(xiàn)。在章末，還有對該章精華內(nèi)容的總結(jié)回顧。
