Auto dimming system of automobile HID headlamp based on LIN bus Abstract: Aiming at the requirement of auto dimming for automobile HID headlamps, this paper designs a set of headlamp automatic dimming system based on LIN bus. Introduced the overall design scheme of the system.....

OSI seven-layer model and its functions At the end of the 1970s, the International Organization for Standardization ISO proposed an open system interconnection reference model. Protocol layering greatly simplifies the complexity of network protocols, which is actually a very .....

Common network topology The topology of the LAN defines the method of organizing network devices. The LAN has a variety of topologies such as bus, star, tree ring, and network. These topological structures are logical structures and have no inevitable relationship with the a.....

Dedicated line introduction The dedicated line is a transparent physical transmission channel. Due to its ease of use and wide coverage, it is widely used in enterprise network interconnection and private line Internet access. The obvious shortcomings of the dedicated line ar.....

Abstract: Two integrated circuits (ICs) and some associated components form a voltage-controlled sawtooth generator that costs less than $ 3 and produces an auxiliary square wave at the same frequency. The generator is useful in a variety of applicaTIons. Its sawtooth waveform .....
