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 super-junction structure, which has P-type pillar layers as shown left,
realizes high withstand voltage and ON-resistance lower than the conventional
theoretical limit of silicon.
This Delphi 4.0 example uses the MapX Ver 4.0 OCX Control. The main goal of this example is
to show the use of the new object editing capabilities in MapX Ver 3.51. The program show how
to perform functions such as adding a new layer adding lines and
points, and editing a layers data.
Using a holistic approach to teaching developers the ins-and-outs of GNU/Linux programming using APIs, tools, communication, and scripting, this book introduces programmers to the environment from the lowest layers to the user layers.
The Unisoft software module GERBER CONNECTION (CNC-BRIDGE). GERBER CONNECTION has all the features of VIEW-MARKUP and adds the ability to open multiple gerber file layers and add information to components. It is always the preference to use the CAD data vs. gerber data. If you do not have the CAD data then GERBER CONNECTION can help.
DirectFB is a thin library that provides hardware graphics acceleration, input device handling and abstraction, integrated windowing system with support for translucent windows and multiple display layers on top of the Linux Framebuffer Device.
A Cross-browser JavaScript DHTML Library which adds Drag Drop functionality and extended DHTML capabilities to layers and to any desired image, even those integrated into the text flow.
