While looking for something at Google, I discovered there is a way to search for patents! My father-in-law, who is over ninety is a retired engineer and a graduate of Brown University in Providence. I knew he held some patents as he told me some years ago when he and I worked on some computer programming tasks together. I didn't know how many and I am sure he will be surprised when I show him what's out on the Internet.
It's fun and I thought you might like to try it so type his name into the Patents search at Google.
