This weeks I stumbled across what seemed like a very old-fashioned design for a slide rule. Curious, who would seek patent protection for something seemingly outdated, I found – our government. More specifically, the super-secret National Security Agency.
Seems the NSA provides a rare glimpse into their inner workings. It appears the agency that otherwise deals with breaking sophisticated cipher codes has a heart for good old technology. But then: Keeping secrets is still in their blood: The original design patent application was filed with a non-publication request, even though design patents don’t publish before issue anyway. Probably just to make sure.
Wonder what slide rule they use to read AES encrypted messages…










Microsoft was just awarded design patent D644654 for icons, that somehow look like liquid-filled balls. Any guesses what those may be meant for?
