This is believed to be the first book that takes a view of nanotechnology from a telecommunications and networking perspective. Nanotechnology refers to the manip- ulation of materials at the atomic or molecular level. Nanotechnology is getting a lot of attention of late not only in academic settings and in laboratories around the world, but also in government and venture capitalists’ initiatives. There now is a major drive to commercialize the technology by all sorts of firms, ranging from start- ups to Fortune 100 companies.

Sensors are points ofcontact betweenthe material world ofatoms, mass, andenergy and the seemingly immaterial world of information, computation, and cognition. Linking these two domains more tightly yields all sorts of practical benefits, such as improvedinputdevicesforcomputers,moreeffectivemedicaldevices(implantedor worn), more precise agricultural operations, better monitored buildings or bridges, more secure payment systems, and more reliable sensor–actuator control systems. There are many settings in which tighter coupling between digital and physical planes can enhance safety, security, performance, and reliability.

HRVAS is a complete and self-contained heart rate variability analysis software (HRVAS) package. HRVAS offers several preprocessing options. HRVAS offers time-domeain, freq-domain, time-frequency, and nonlinear HRV analysis. All results can be exported to an Excel file. For processing many files HRVAS offers a bach processing feature. All settings/options can be saved to a .mat file and reloaded for future HRV analysis. Upon starting HRVAS all previously used settings/options are loaded.

首先下載軟件,解壓軟件,安裝在程序中找到SEGGER,選里面的J-FLASH,進(jìn)入界面,剛開始的那個界面可以忽略,不用建project也可以;單擊菜單欄的“Options---Project settings”打開設(shè)置,進(jìn)行jlink配置;正在General選項,選擇“USB”,一般都是默認(rèn)配置,確認(rèn)一下即可;然后在CPU選項,選擇芯片型號,先選擇“Device”才能選擇芯片型號,芯片型號,要根據(jù)你使用的芯片進(jìn)行選擇;在Target interface選項 里面選擇SWD模式;首先Target里面選“Connection”連接目標(biāo)芯片,然后 Target--Auto進(jìn)行程序燒寫;首先Target里面選擇“Connection”連接目標(biāo)芯片,然后 Target--Auto進(jìn)行程序燒寫.SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years in embedded development. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments.

對于文件名為xx.ms11的文件,需要首先安裝multisim11仿真軟件才能使用;對于文件名為xx.ms11的8051單片機仿真電路文件(或者PIC彈片機仿真電路文件),不僅需要首先安裝multisim11仿真軟件,還需要有相關(guān)的工程文件(multisim11中默認(rèn)存放在C:\Documents and settings\Windows\My Documents\National Instruments\Circuit Design Suite 11.0\MCU Workspaces路徑\...中),因此建議讀者進(jìn)行單片機仿真時,最好按照光盤中給出的仿真電路圖,在multisim11重新繪制仿真電路,重新建立相關(guān)的工程文件,以保證仿真的順利進(jìn)行。當(dāng)讀者創(chuàng)建簡易數(shù)字頻率計的8051單片機仿真電路時,必須在MCU Wizard的第2步中將工程文件類型設(shè)置為“下載外部文件”類型(External hex file);具體方法請讀者參考與光盤配套的書籍的第8章和光盤的“簡易數(shù)字頻率計\軟件流程\調(diào)試”文件路徑中的“調(diào)試.txt”文件(其中的第0步)和光盤的“簡易數(shù)字頻率計\軟件流程\調(diào)試”文件路徑中"圖1"文件。簡易數(shù)字頻率計由于采用了“下載外部文件”的工程類型,因此MCU Code Manager窗口中的設(shè)置較簡單:只要按照光盤中“簡易數(shù)字頻率計\軟件流程\調(diào)試”文件路徑中的“圖3”文件設(shè)置好后綴為.hex的外部文件在磁盤中的路徑即可。
