The increasing number of mobile terminals facilitates the development of context-aware applications. However, developing a context aware application is still a complex work, which involves mechanisms of context acquisition and context processing. In order to release the developer's burden, many context aware frameworks emerged. But none of them yet has sufficient consideration of mobile environment characteristics. Besides, restricted to the mobile platform, the developed application could not achieve cross-platform deployment. A cross-platform context-aware application developing framework for mobile terminals is proposed in this paper. This framework could shield system differences, centralize context acquisition, context modeling, context storing, context interpretation and context aggregation for many context aware applications on the same terminal. Applying the framework, data of same sensor would not be duplicated processed by many context aware applications. Context aware application would be built faster. And mobile terminal resources would be used more efficiently.

The paper illuminates the designed automatic weld control system. The RAC calibration arithmetic considering radial distortion is introduced, and according to the actual conditions of this weld system, the inchoate rapid calibration arithmetic is designed. Finally combined with the precision characteristic of the non-linear RAC calibration arithmetic and the concision characteristic of the inchoate rapid arithmetic, the improved automatic calibration arithmetic with six parameters is proposed, which achieves satisfied result.

The measurement of variety of non-electricity such as temperature and humidity is so important. To measure the temperature and humidity accurate with low cost is especially necessary. An open platform for multi-sensors including temperature and humidity etc. measurement and control is proposed. Three layers distributed architecture is adopted, and the distributed intelligent nodes are designed. All nodes are connected to the embedded computer through RS-485 and the data processing is accomplished. The software is developed with WinCE and good user interface is obtained. Other sensor modules are also supported and processed in the open platform. The results of application show that the platform is of low-cost, good openness, versatility and supporting complex industrial applications.
