Radio frequency identification (RFID) and Wireless sensor networks (WSN) are the two key wireless technologies that have diversified applications in the present and the upcoming systems in this area. RFID is a wireless automated recognition technology which is primarily used to recognize objects or to follow their posi- tion without providing any sign about the physical form of the substance. On the other hand, WSN not only offers information about the state of the substance and environment but also enables multi-hop wireless communications.

Recent work has shown that convolutional networks can be substantially deeper, more accurate, and efficient to train if they contain shorter connections between layers close to the input and those close to the output. In this paper, we embrace this observation and introduce the Dense Convo- lutional Network (DenseNet), which connects each layer to every other layer in a feed-forward fashion.

如果了解FAT的系統(tǒng)結(jié)構(gòu)，并理解了FatSL的軟件結(jié)構(gòu)，那么文件系統(tǒng)移植并不困難（其實(shí)文件系統(tǒng)移植都是大同小異的）。本文給出的例子是基于STEVAL-CCM007V1硬件平臺，通過NFTL層（NAND Flash Translation Layer）在NAND Flash上建立該文件系統(tǒng)的情況。

基于藥物治療在臨床治療中的重要性,分析目前服藥提醒裝置存在的不足,以STM32F103VET6單片機(jī)為控制核心,設(shè)計(jì)了一種多功能電子藥箱。該系統(tǒng)包括顯示模塊、語音模塊和數(shù)據(jù)存儲模塊。顯示模塊通過觸摸屏電路和LED指示燈電路,與語音模塊相配合,實(shí)現(xiàn)了服藥提醒及指導(dǎo)的功能;數(shù)據(jù)存儲模塊通過EEPROM存儲電路,能夠?qū)崿F(xiàn)掉電時服藥信息不丟失的功能。并且為了實(shí)現(xiàn)電子藥箱的智能化控制,開發(fā)了手機(jī)APP,兩者之間可通過WIFI進(jìn)行數(shù)據(jù)通信。經(jīng)測試,該藥箱能夠有效地幫助慢性病患者按時、定量、正確服用藥物,適合在家庭中推廣使用,具有較高的應(yīng)用價值和實(shí)踐意義。Based on the importance of drug therapy in clinical treatment, this paper analyzes the shortcomings of current drug reminder devices, and designs a multi-function electronic medicine box with STM32 F103 VET6 microcontroller as the control core. The system includes a display module, a voice module, and a data storage module. The display module cooperates with the voice module through the touch screen circuit and the LED indicator circuit to realize the function of reminding and guiding the medicine;the data storage module can realize the function of not losing the medication information when the power is off through the EEPROM storage circuit.After testing, the medicine box can effectively help chronic diseases patients to take drugs on time, in a quantitative and correct manner,and is suitable for popularization in the family, and has high application value and practical significance.
