7、ased higher-layer protocols. All activities are based on CiA members interest, participation and initiative. CiA representatives actively support international standardization of CAN protocols and represent the members interest in national and international standardization committees, such as ISO an
8、d IEC. CiA members initiate and develop specifications that are then published as CiA standards. These specifications cover physical layer definitions as well as application layer and device profile descriptions. All the technical development needs to be marketed in order to reach a broad audience a
9、nd to further the CAN technology. For this purpose there are several marketing groups within the CiA. Access to these groups is open for all CiA members, just as in the technical groups. Participation may be active or passive, regular or irregular, just as the individual member company wishes. All m
10、arketing measures to promote the CAN technology are feasible. At the moment CiA organizes joint marketing activities including stands and booths at fairs and exhibitions. CiA publishes the CANopen Product Guide on CD-ROM and in the web, application-specific brochures and the CAN Newsletter magazine.
11、 They provide a CAN product database available to all on the web. CAN specifications can downloaded online. Further activities are free-of-charge CANschools in selected countries and CAN and CANopen seminars as well as In-house seminars. Also, CiA representatives speak at international conferences a
12、nd fairs about CAN and invite other organizations to jointly develop profiles.中国矿业大学机电工程学院-张有忠 版权所有 2012-08现场总线技术7About KVASERnOne of the worlds leading CAN development companiesnwith our main operations focusing on automotive, trucks, industrial automation, and medical equipment.nWe cover a broad s
13、pectrum of competence and capability in CAN, with development of innovative and creative CAN products tailor- made for the engineer. Our products are spread in 18 segments, and our own strength and strategic partnerships enable us both to compete and to collaborate in all international markets. Kvas
14、er has the world as its market, but research, development and production are carried out principally in Sweden. nWe began in the early 1980s to specialize in Distributed Embedded Control Systems. A few years later the CAN protocol was published and the first CAN chip became available. Our founders q
15、uickly realized the excellent features of CAN, and made the strategic decision to dedicate its resources to CAN solutions, and became one of the very first companies in the CAN industry. 中国矿业大学机电工程学院-张有忠 版权所有 2012-08现场总线技术8About SAEnThe Society of Automotive Engineers has more than 84,000 members - engineers, business executives, educators, and students from more than 97 countries - who share information and exchange ideas for advancing the engineering of mobility systems.
