This method is very restrictive for the following reasons: (i) a dedicated additional pin and a specific off-chip circuitry on the PCB are required thus increasing cost; and (ii) setting the output voltage by adjusting an analog voltage is not aligned with the current trend of automotive ECUs to make more and more use of digital interfaces and networking.
After all, during the 1970s and early 1980s, Xerox PARC researchers almost single-handedly developed many of the technologies underlying the modern PC: laser printing, "point and click" graphical interfaces, and Ethernet networking.
Keep branching out and networking.
In particular, it was predicted that higher levels of network programmability will result from separation of hardware from software, availability of open network interfaces, virtualization of networking infrastructure, and rapid creation and deployment of network services.
At the same time, since the new storage systems use the so-called small computer system interface (SCSI) networking standard, it won't compete with the fiber-channel products built by EMC that Dell has been selling to its customers.
However, in the same way that the plug-and-play initiative in 1992 between Microsoft, Compaq and Intel introduced common interfaces for networking devices, 1999 is likely to be the year of the "convergence convergence": different industry leaders coming together to incorporate their separate technologies and create new consumer products.
For example, engineers at Xerox Corp. in the 1970s pioneered key inventions in information technology (such as the graphical user interface and Ethernet computer networking).
The research activities within the group encompass all levels of communication systems, from antennas & propagation, air interfaces, PHY, MAC, networking layer up to the service support platforms and distributed applications and user interfaces.
