1 要转换的SF1.x数据库文件必须为1.4以上的版本, 不然可能无法正常转换 2 由于转换要求2.0数据库文件必须无任何论坛、用户、帖子数据, 因此随本转换程序提供了一个真正的数据全空的数据库文件!(注意随SF发布自带的那个数据库文件内已有论坛版块等数据, 不能用于本转换程序!) 3 请将SF1.x数据库文件与SF2.0数据库空文件放在与sf1up.asp同目录下, SF1.x数据库文件命名为sf1.mdb, SF2.0空数据库文件命名为sf2.mdb, 然后再运行sf1up.asp-a change to the database files must SF1.x to version 1.4 and above, or may not be able to change the normal requirements resulting from the conversion of two 2.0 database files must be no forum for users to post data, with the conversion process provides a truly the It was all empty database files! (Note : With the release of SF"s own database files that contain data such as the Forum"s plate, not used in the conversion process!) I should be grateful if SF1.x three database files and database SF2.0 empty file on the same directory with sf1up.asp, SF1 . x database files named sf1.mdb, SF2.0 empty database file named sf2.mdb and then running sf1up.asp

This application report discusses the design of non-invasive optical plethysmography also called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). The pulsoximeter consists of a peripheral probe combined with the MCU displaying the oxygen saturation and pulse rate on a LCD glass. The same sensor is used for both heart-rate detection and pulsoximetering in this application. The probe is placed on a peripheral point of the body such as a finger tip, ear lobe or the nose. The probe includes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) and the other in the infrared spectrum (940nm). The percentage of oxygen in the body is worked by measuring the intensity from each frequency of light after it transmits through the body and then calculating the ratio between these two intensities.
