摘要：The continued development of CMOS technology and the emergence of new applications demand continued improvement and enhancement of compact models. This paper outlines the recent work of the BSIM project at the University of California, Berkeley,including BSIM5 research, BSIM4 enhancements, and BSIMSOI development. BSIM5 addresses the needs of nano-CMOS technology and RF high-speed CMOS circuit simulation. BSIM4 is a mature industrial standard MOSFET model with several improvements to meet the technology requirements. BSIMSOI is developed into a generic model framework for PD and FD SOI technology. An operation mode choice,via the calculation of the body potential △Vbi and body current/charge,helps circuit designers in the trend of the coexistence of PD and FD devices.

摘要：现有的客运汽车监控系统功能不完善,对于环境监测、远程监控、联动报警等任务不能很好完成,基于B/S架构的客运汽车监控系统能够较好实现这些任务。整个系统可分为车载终端、服务器端、客户端。车载终端主要实现对车内环境参数、视频音像的采集传输;服务器端主要负责响应、处理各请求;客户端主要实现人机数据交互。客运公司管理中心通过浏览器即可随时了解车内的环境参数及人员情况和车辆运行的状况。

摘要：儿童被困车内的事件时有发生,针对这一问题,本文设计了一套基于GPRS技术的智能检测、实时监控、精准定位、安全可靠的防儿童被困车内的紧急救援系统。该系统通过热释电红外传感器、二氧化碳传感器、车门门框触电开关及GPS模块的组合,检测出有人员遗留在车里时可能出现的危险情况,通过STM32控制汽车车窗下降实现车内通风换气,同时通过GPRS通信模块给车主发送救援短息并自动拨打车主手机,同时将车内实时信息反馈到服务器,实现远程自动寻呼报警,客户端实时监控引导救援。
