Design and implementation of testing platform of small form-factor pluggable transceiver based on LabVIEW [PDF]
, 2011 介绍了一种利用lAbVIEW构建SfP(SMAll fOrM-fACTOr PluggAblE)光模块测试平台的方法。测试平台通过读写计算机并口来映射地址上的数据,控制并口端口的逻辑电平实现计算机并口模拟I2C总线。计算机利用模拟的I2C总线与SfP光模块实现通信。分析了生产者/消费者结构队列状态机并用于设计中,该设计模式可以及时响应前面板动作或外部事件,并且使得状态机的状态变换更加灵活多变。This paper introduces a method of constructing a SFP ...

Study on a remote-control PWM drived mini car based on AT89C51 [PDF]
, 2008 TX-2B编码的控制按键基带信号经ASK振幅键控后由30 MHz的载波发射,通过超再生接收电路再由RX-2B解码后,无线信号转化为数字脉冲信号并输入到AT89C51。从而控制单片机输出PWM信号,控制功率管驱动电路,配合直流电动机及现有玩具小车机械传动装置,实现遥控电动玩具车的前进、后退、加速、左右转等功能。The base-band signal,coded by TX-2B as the control key,is transmitted on 30 MHz carrier wave after ...

Research on consistency control of nickel plating and investigation on corrosion mechanism and protection technology of the copper layer [PDF]
, 2012 电镀技术不仅仅在传统工业中扮演重要角色；在高新技术产业，如现代电子技术、微电子技术、通讯技术及产品制造上发挥愈来愈大的作用。本文在厦门宏发电声股份有限公司电镀车间现有滚镀工艺基础上，针对滚镀镍与滚镀铜工艺，详细研究了镀镍层厚度一致性控制工艺与镀铜层腐蚀与防护机理。 1、通过对镀液组份的研究，发现不同的镀液添加剂对镀液的极化度不尽相同，选择合适的光亮剂从而获得更高的阴极极化度可以提高镀层一致性。通过向镀液添加导电盐，降低镀液电阻率，也能够改善镀层一致性。 2、通过对滚镀生产设备的研究 ...
