U.S. patents covering time keeping mechanisms

“An inventor fails 999 times, and if he succeeds once, he’s in. He treats his failures simply as practice shots. It doesn’t matter if you try and try and try again, and fail. It does matter if you try and fail, and fail to try again.”
Charles Kettering
