Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols and security certification programs developed by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the previous system, WEP (Wired Equivalent Privacy).[1] WPA (sometimes referred to as the draft IEEE 802.11i

我们都知道Intel一直在试图将Android带到自己的Atom平台上，1个月前他们宣布了Atom已经可以成功运行Android和Meego系统，今天他们又透露了这颗Atom芯片的一些技术细节。 这颗Atom芯片属于Z6xx系列，在手机上可达到1.5GHz的主频，在平板上更是可以摸高到1.9GHz的速度，足以提供1080p视频的解码和720p视频的录制，帮助3D显卡闲置功耗降低50倍以上，等于多赋予电池10天的待机。这个新的芯片组应该可以提供长达2天的音频回放和4-5小时的视频浏览。 对Android的支持方面，Z6xx平台可支持标准的WiFi、3G/HSPA和WiMAX无线连接。之前传说Google和索尼联手打造的Android TV就内置了Intel的Atom芯片，那么很可能就是Z6xx系列，我们会在5月19日的Google I/O大会上见到运行Android的Atom芯片的庐山真面目。

XLP Energy Harvesting Development Board The XLP 16-bit Energy Harvesting Development Kit is a true development platform for realizing energy harvesting applications. The Microchip nanoWatt XLP PIC MCUs are ideal for these low power applications with sleep currents down to 20nA, active mode currents down to 50uA/MHz, code execution efficiency, and multiple wake-up sources. Powered only by light, the XLP kit enables rapid prototyping of low power applications such as RF sensors, temperature/environmental sensors, utility meters, remote controls, and security sensors to name just a few. For software development and programming, the kit includes the PICkit 3 programmer/debugger for use with the Microchip’s free MPLAB™ Integrated Development Environment.
