YADA series IC card intelligent electronic lock is a new generation intelligent product developed that synthesized a lot of advanced technology such as computer, microelectronics, and prec ision machinery manufacturing.

A background restraining method is proposed,it uses an electronic shutter combines a fixed aperture to control the exposure quantity of the CCD sensor,and makes the missile targets sharply focused in the CCD image.

With the combination of an electronic shutter and a variable diaphragm in a CCD video camera system, light is adjusted automatically under the control of a single chip microcomputer.

A special CCD camera is designed,which has such functions as manual and automatic electronic shutter,γ correction,and external synchronization.

Construction and work principle of electronic throttle pedal are introduced in detail,the voltage signal is identified by fuzzy control system and output signal is reformed and filtered by OR module and filter,lastly better torque signal which reflects the operation attempt of driver is gotten.

Construction and work principle of electronic throttle are introduced in detail,an electronic throttle detection system based on PCI-1712 data acquisition card is designed and realized.

Electronic throttle is a kind of flexible control system, controlled by the motor-driven throttle, realized position control to achieve precise control.
