Great guy!But Jim can't name an integrated circuit he designed. He can remember that the guy prompted Jim to come up with an interesting innovation, but can't bring himself to document anything Frederiksen himself was responsible for. Trump and Larkin behave like that. -- Bill Sloman, Sydney

And I have his paper on a Monolithic-Sonar-System. There are likely many more papers if one were to look. He also had patents, which I have stored in my computer. -- Thanks, - Win

You were there, please tell us more of Tom's story. And about these papers and patents, which product part numbers do they correspond to? -- Thanks, - Win

And about these papers and patents, which > product part numbers do they correspond to?Most of the co-inventors were young bucks at Motorola when I was there, who then fled to NSC with Solomon and Frederiksen. That's how I recognize the names. I'll browse the patents and can probably identify those products that are Motorola's. As for those at NSC, I might, or might not, be able to guess products. I was never at NSC... my foray into Californica was to Philco-Ford for 8 months in 1968 along with John Welty, then right back to Motorola. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | STV, Queen Creek, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Thinking outside the box... producing elegant solutions.
