In this paper we present a classifier called bi-density twin support vector machines (BDTWSVMs) for data classification. In the training stage, BDTWSVMs first compute the relative density degrees for all training points using the intra-class graph whose weights are determined by a local scaling heuristic strategy, then optimize a pair of nonparallel hyperplanes through two smaller sized support vector machine (SVM)-typed problems. In the prediction stage, BDTWSVMs assign to the class LABEL depending on the kernel density degree-based distances from each test point to the two hyperplanes. BDTWSVMs not only inherit good properties from twin support vector machines (TWSVMs) but also give good description for data points. The experimental results on toy as well as publicly available datasets indicate that BDTWSVMs compare favorably with classical SVMs and TWSVMs in terms of generalization

There is an unprecedented enthusiasm for radio frequency identification (RFID) technologies today. RFID is based on the exchange of information carried by electromagnetic waves between a LABEL, or tag, and a reader. This technology is currently in full economic expansion, which has manifested itself in widely backed research activities, some of which will be examined in this book.

PT2262/2272是一对带地址、数据编码功能的红外遥控发射/接收芯片。其中发射芯片PT2262-IR将载波振荡器、编码器和发射单元集成于一身，使发射电路变得非常简洁。 接收芯片PT2272的数据输出位根据其后缀不同而不同，数据输出具有“暂存”和“锁存”两种方式，方便用户使用。后缀为“M”为“暂存型”，后缀为“L”为“锁存型”，其数据输出又分为0、2、4、6不同的输出，例如：PT2272-M4则表示数据输出为4位的暂存型红外遥控接收芯片。

Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the protection limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltages are also present on circuits that are isolated from mains. The Agilent 34401A are designed to safely withstand occasional transient overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltages could exceed this level. Additional Notices Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC This product complies with the WEEE Directive (2002/96/EC) marking requirement. The affixed product LABEL (see below) indicates that you must not discard this electrical/electronic product in domestic household waste. Product Category: With reference to the equipment types in the WEEE directive Annex 1, this product is classified as a "Monitoring and Control instrumentation" product. Do not dispose in domestic household waste. To return unwanted products, contact your local Agilent office, or see www.agilent.com/environment/product for more information. Agilent 34138A Test Lead Set The Agilent 34401A is compatible with the Agilent 34138A Test Lead Set described below. Test Lead Ratings Test Leads - 1000V, 15A Fine Tip Probe Attachments - 300V, 3A Mini Grabber Attachment - 300V, 3A SMT Grabber Attachments - 300V, 3A Operation The Fine Tip, Mini Grabber, and SMT Grabber attachments plug onto the probe end of the Test Leads. Maintenance If any portion of the Test Lead Set is worn or damaged, do not use. Replace with a new Agilent 3413

第一步：新建PCB工程文件 并向工程文件里添加PCB文件和原理图文件 第二步：元件库、封装库设计 部分元器件厂商或者经销商不提供元件库和封装库，只给了元器件尺寸图，所以需要自行设计元件 库文件或是封装库文件 元件库设计： 新建 .SchLib 文件：File -> New -> Library -> Schematic Library 使用Place下拉菜单或使用快捷工具栏放置图形，引脚等，记得保存！ 封装库的设计 新建.PcbLib文件：File -> New -> Library -> PCB Library 使用Place下拉菜单或使用快捷工具栏，画线，放置孔位，记得保存！第三步：原理图的绘制 新建.SchDoc文件 ：File -> New -> Schematic 添加元器件库和封装库 在软件底部菜单栏System中勾选Libraries，打开侧面工具栏 在侧面工具栏中点击“Libraries...” -> “Add Library”找到自己保存的库文件并添加 添加各元器件 可直接从侧面工具栏中选择元器件拖入原理图中，在拖动过程中按Tab键修改元器件信息 添加网络标识Place -> Net LABEL 快捷键（PN） 确定各元器件封装 打开封装管理器Tools -> Footprint Manager 快捷键（TG） 可挨个修改、检查各元器件封装
