基于单片机的火灾探测和预警系统设计-英文翻译

Abstract The paper mainly deals with the design of hardware for an automatic fire fighting system, which aimed at closed combustible places. This system adopts single chip microcomputer with smoke sensor and temperature sensor as the detective devices. By using the single chip microcomputer, it c..
火灾报警-英文翻译

The traditional electron safe alarm system mainly is through the sensor automatic detection, produces the alarm, sends out the alarm from the scene or reports to the police through the special electric cable near distance, and thus causes people's vigilance. Through many years research and the de..
基于TMS320C242DSP的无刷无位置传感器直流电机的速度控制-英文翻译

Abstract The Brushless DC (BLDC) variable-speed drive is widely used because of its particularly high mechanical power density, simplicity, and cost effectiveness. A software rotor position generation has been implemented on the DSP Controller family, thus saving the mechanical position sensor co..
网络服务的个人信任的装置年复一年的多级安全-英文翻译

Abstract. In this paper we revisit the concept of mandatory access control and investigate its potential with personal digital assistants(PDA). Only if applications are clearly separated and Trojans cannot leak personal information can these PDAs become personal trusted devices. Limited processin..
图像增强-英文翻译

Image enhancement processes consist of a collection of techniques that seek toimprove the visual appearance of an image or to convert the image to a form bettersuited for analysis by a human or a machine. In an image enhancement system, thereis no conscious effort to improve the fid elity of a re..
一种新颖的用于消除PWM逆变器输出共模电压的有源滤波器-英文翻译

Abstract—This paper proposes an active common-noise can-celer (ACC) that is capable of eliminating the common-mode volt-age produced by a pulsewidth modulation (PWM) inverter. An emitter follower using complementary transistors and a common-mode transformer are incorporated into the ACC, the des..
