模拟/混合信号：传感器连接是信号调理成功的关键 作者：Gene Heftman，特约编辑，《Electronic Design》...

信号灯受一个启动开关控制，当启动开关接通时，系统开始正常工作，且先南北红灯亮，东西绿灯亮；当启动开关断开时，所有信号灯熄灭；南北绿灯和东西绿灯不能同时亮，如果同时亮则应报警后关闭信号灯系统。-To start signal by a switch control, when the start switch connected to the system started to work, and the first north-south red light, green things when the start switch off all lights extinguished north-south and east-west green light green light can not be at the same time, if At the same time, bright lights should be shut down after alarm system.

1997年9月，NIST征集AES方案，以替代DES。 1999年8月，以下5个方案成为最终候选方案：MARS, RC6, Rijndael, Serpent, Twofish。 2000年10月，由比利时的Joan Daemen和Vincent Rijmen提出的算法最终胜出。（ Rijndael 读成Rain Doll。） http://www.esat.kuleuven.ac.be/~rijmen/rijndael/-September 1997, NIST AES assembly program to replace DES. In August 1999, the following five programs become final candidate : MARS, RC6, Rijndael, Serpent, Twofish. In October 2000, from Belgium J.J.K.Daemen3 Joan and Vincent Rijmen proposed algorithm eventually win. (Rijndael read Rain Doll.) Http://www.esat.kuleuven.ac.be/ ~ rijmen/rijndael /
