书籍 Multiscale+Simulation+Approach
Battery systems for energy storage are among the most relevant technologies of the
21 st century. They – in particular modern lithium-ion batteries (LIB) – are enablers
for the market success of electric vehicles (EV) as well as for stationary energy
storage solutions for balancing fluctuations in ...
电源技术 DN445微型模块LED驱动器
 
Once relegated to the hinterlands of low cost indicatorlights, the LED is again in the spotlight of the lightingworld. LED lighting is now ubiquitous, from car headlightsto USB-powered lava lamps. Car headlights exemplifyapplications that capitalize on the LED’s clear advantages&mda ...
书籍 Time-Varying Channels
Wireless communications has become a field of enormous scientific and economic interest. Recent
success stories include 2G and 3G cellular voice and data services (e.g., GSM and UMTS), wireless
local area networks (WiFi/IEEE 802.11x), wireless broadband access (WiMAX/IEEE 802.16x), and
digital broad ...

书籍 System Requirements Analysis
The serious study of the practice of how to determine the appropriate content of a
specification is a seldom-appreciated pastime. Those who have the responsibility to
design a product would prefer a greater degree of freedom than permitted by the con-
tent of a specification. Many of those who would ...

技术资料 一种基于HID规范的可定义功能的医用图像采集脚踏控制器的研制
为解决传统医用脚踏存在的问题,本文在不修改任何医疗参数的情况下,设计并研制了一种可对多种图像采集设备或软件进行自定义采图及录制功能的脚踏设备。该设备主要基于HID规范,使用UTS2210模块,通过KeilC编程结合STC-12C5A60S2单片机向上位机串口发送控制信号来实现采图。实验结果显示该医用脚踏控制器成功率为98%。经过近一 ...
单片机编程 驱动程序与应用程序的接口
有两种方式可以让设备和应用程序之间联系：1.&nbsp;通过为设备创建的一个符号链；2.&nbsp;通过输出到一个接口WDM驱动程序建议使用输出到一个接口而不推荐使用创建符号链的方法。这个接口保证PDO的安全，也保证安全地创建一个惟一的、独立于语言的访问设备的方法。一个应用程序使用Win32APIs来调用设备。在某个Win32 APIs和 ...
