Robious, it has a very rigorous, and yet, user-friendly, design. It's got some key features, but no so key, no features that can't be done in other programs. I think the interface is very decent. It's very, very well organized. It was designed in one of our, under one of our world class software developers, in our world class research and development group, but is a very functional and usable product.
My interest is in the fact of how can we get the right fit for user, that's right. The computer -- the software and the hardware, that's the key technology. Now, you can have an inexpensive CAD system, but what you don't have is good responsiveness from the user. And, so, when you take that inexpensive CAD system, are you going to be able to bring the user to the computer, very quickly, very efficiently? So, the key technology in it is a tight partnership with usability.
Believe it or not, I think it was the streetlights that made useful the light bulb that made lighting possible. Programmable logic controllers (PLCs) are the mechanical brains that direct power to the lights. They handle dimming and on-off control and are the core components of any lighting system. And the PLCs that are used in streetlights today, heres''s a complex device that has an analog I/O card and that contains the analog...
I get to ask a question back, of course. By the way, these are telecommunications outlets, not household outlets. So, the PLC's have led electrical outlets. Now, these PLCs are analog devices, and as technology has evolved, we have been able to convert analog devices into digital ones. What have we gotten in return?
We have gotten considerably better performance. We have gotten greater reliability, so it - our substations are more reliable because we converted to digital devices. So, I think, we have greatly benefited and we've sold that to the customer.
