The paper presents a mechatronic system designed to simulate the surroundings of night-driving roads in mesopic vision. Visual Performance in the mesopic range to define mesopic visual performance is thought of the most essential methods to research the mesopic vision. And there is no standard model to evaluate the mesopic performance. Therefore, the experimental system BJ-MV2 is designed to measure and record the reaction time. By changing the parameters of mesopic environment, we get a series of experimental data and calculate curve-fitting data. According to the curve, the tendency of reaction time appears clearly and BJ-MV2 is proved to be a reliable system for researching mesopic vision.

Design the mechanical structure of automatic CNC grooving and bending machine based on the modular design method, and the three-dimensional mechanical structure model is created out using Pro/E; design the control system of automatic CNC grooving and bending machine based on the open CNC system theory, the control structure takes PC and motion control card method, and the control software is developed by Visual C++ 6.0. Finally the automatic equipment has been developed which has advantages of automatically processing, high precision and low price.

As the evolution of automobile industry, the application of cars has been gradually extensive. Nowadays, automobiles have been an essential part of modern society .The development of car equipments has also been accelerated by the growing popularity of the automobiles. Meanwhile, if these equipments are not regulated rationally, they also rouse extra consumption of power stored in car batteries. GPS system, as an example, causes unnecessary consumption while the automobiles are at rest. As the power loss of automobiles may cause series of dangers, such situation should be avoided. The article provides a feasible way to make an intelligent control on power supply system of automobiles through AVR single chip programming. Thus helps regulate the usage of the car batteries. From this, automobile securities can be enhanced.

Because the current research on traffic level has not yet been achieved classification, it cannot timely and effectively provide the basis for the public transportation and safety management of the traffic control department. Introduce traffic safety index based on toll data to evaluate freeway traffic levels. Firstly, combined with the relevant indicators of traffic engineering, put forward the concept of freeway traffic safety index; secondly, calculate the traffic safety index by analyzing real-time toll data; finally, in order to improve the accuracy of evaluation, have an optimization of traffic safety index definition. Application on the Beijing-Hong Kong-Macao freeway shows that traffic safety index can be combined with monitoring data to evaluate the condition of road sections and the road network, and its historical data can be used to predict the road traffic conditions, and provide effective guidance for freeway traffic safety operation.

This paper proposes an algorithm to generate and render fireworks in real-time based on programmable graphics hardware, which divides the queue into several regions to save the time when waiting for CPU, and uses the XML external data and XNA framework to achieve the fast simulation of fireworks. The experimental results show that the algorithm can draw the fireworks vividly, meets the demand of real-timing very well, and has a great scalability.
