Login Manager V3.0(LM3.0) is an authentication system which can integrate with any existing website that meets the requirements. LM3.0 provides a gatekeeper where user must be authorized before entering the membership secured areas. Features: 1. Flexibility LM3.0 allows administrator to integrate it with the current unprotected website. This is especially useful if major changes are going to be painful. With LM3.0, you re just one step towards getting the security you needed most. 2. Speed LM3.0 uses PHP and MySQL which enables fast data transactions.

Wireless range extenders or wireless repeaters can extend the range of an existing wireless network. Range extenders can be strategically placed to elongate a signal area or allow for the signal area to reach around barriers such as those created in L-shaped corridors. Wireless devices connected through repeaters will suffer from an increased latency for each hop. Additionally, a wireless device connected to any of the repeaters in the chain will have a throughput that is limited by the weakest link between the two nodes in the chain from which the connection originates to where the connection ends

现有基于MAX7219芯片的数码管驱动电路只适用于小尺寸LED，为扩展其使用范围，在介绍动态显示芯片MAX7219功能的基础上，提出了一个基于该芯片的8位高亮度8英寸数码管驱动电路。电路保留了MAX7219芯片的功能强大、编程简单等优点，通过74LS273锁存器和ULN2803达林顿驱动器，实现了对任意大尺寸数码管提供较高电压和电流驱动的静态显示，并亮度可调。 Abstract: The existing display-driving circuit based on MAX7219 was only applicable to small-size LED. To expand its use, based on the function introduction of dynamic display chip MAX7219, a display-driving circuit for high-brightness 8-bit LED with the size of 8-inch was proposed. The advantages of MAX7219 were retained, such as powerful function and simple programming. Static display with adjustable brightness for large-size LED with higher voltage and current was achieved with the help of 74LS273 and ULN2803.

为降低成本和解决现有膜片钳放大器系统中PC机的干扰问题，研究了一种基于单片机的膜片钳放大器小系统。该系统采用ADI公司生产的ADuC841作为控制核心，并且配置相应的液晶显示模块LCM3202401。模拟电路部分采用高输入阻抗的AD8627实现微电流信号的采集，并由后级电路进行信号的放大和电阻电容的补偿。它具有硬件电路简单、体积小、使用方便的特点。既可以单独作为小系统实现采集和显示，也可以通过红外方式和PC机进行通讯，在PC机上进行信号的处理。 Abstract: In order to reduce cost and resolve the interferential problem with PC in existing patch clamp amplifiers, a small patch clamp amplifier system design based on microcontroller is studied. It adopts a new high performance microconverter ADuC841 by the ADI as the control core in the system, configuring a liquid crystal module LCM3202401. In the analog circuit, AD8627 with high input impedance is used to detect the low current，signal magnification, as well as resistance and capacitance compensation are accomplished by subsequent circuits. It has the advantage of simple hardware circuit design, small volume and convenient operation. It can either be used as an independent system to measure and show signal detected or transmit to PC by infrared ray.
