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参数的设计与应用 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是一个用PHP编写的搜索引擎，它使用MySQL数据库后台。它的功能有静态和动态页面索引，在HTML内容中用hrefs, areamaps，和frames以及全文本索引构成所有的链接网。搜索结果的外观是可定制外观的，使用一个非常简单的模板系统。

留言本 需要修改的地方都有注释 你可以自行修改 主要有login.jsp和jdbc.java里面关系都数据库连接部分 jdbc你修改编译之后请放到WEB-INF\classes\wu目录下面 数据库采用的是mysql 建表语言是： 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 没有姓名 , 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.

本书包含了许多Ajax技术的设计模式。例如：你应该如何分割数据以便于分配呢？答案是，采用内容分块模式（CONTENT Chunking Pattern）；如何有效地维护状态或至少是维护痕迹呢？答案是，采用持久通信模式（Persistent Communications Pattern）；如何让用户对所有潜在的数据了如指掌呢？答案是，采用无限数据模式（Infinite Data Pattern）。通过书中呈现的九种模式，作者几乎发掘了所有的Ajax理论，这些知识对你将来编写应用程序时制定策略有重大的帮助。每种模式都有相应的章节对其进行论述，每章均以模式的设计意图为开头，然后介绍使用该模式的动机，并列举一系列使用该模式开发的应用程序和与该模式相关联的设计模式。接着，以解决实际问题的方式诠释该设计模式的架构。最后，执行程序通过代码及用户与各种网页的互动形式展现。在章末，还有对该章精华内容的总结回顾。
