一般有使用到無線通信的產品，通常都會在電路板上設計屏蔽框(shielding FRAME)來隔絕電磁干擾(EMI)，現在有些腦筋動得快的廠商想出了使用夾子(clip)來取代屏蔽框的方法，這種夾子不但可以使用SMT打件，而且體積小所以不怕變形。這就是傳說中的屏蔽夾了。

介紹一種基于CAN總線的牽引變電站自動化系統通訊規約的設計，CAN通訊規約采用標準幀，報文采用主動發送和發送查詢兩種處理形式。該設計在城市輕軌與地鐵牽引變電站中的應用表明：可實現間隔層和通訊處理層的數據快速、可靠的交換，提高牽引變電站的安全性和穩定性 。 Abstract: This paper firstly presents a kind of design dealing with communicational protocol to the traction substation automation system based on CAN bus,and then comes up with the ideas that all FRAMEs of CAN communicational protocol should adopt the standard FRAME,and that messages be processed by two ways:sending initiatively and sending quiries.Subway and light rail application shows that the use of the CAN bus is possible to exchange data quickly and reliably between the layers of the middle and the communicational processing,hence to improve the safety and stability of traction substations.

The LPC1700 Ethernet block contains a full featured 10 Mbps or 100 Mbps Ethernet MAC (Media Access Controller) designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control FRAMEs, hardware acceleration for transmit retry, receive packet filtering and wake-up on LAN activity. Automatic FRAME transmission and reception with Scatter-Gather DMA off-loads many operations from the CPU.
