  Hehehe, you can call her the mother of early 802.11 (and Bluetooth).

      Yeah, I think I get it. I mean the analogy is a bit flawed. What she invented is that alike synchronizing the rolls of player pianos, you could build a mechanism that hops frequencies (instead of piano keys) to make remote controlling torpedos resilient against jamming.

      Idk. To me it feels like calling the inventor of three-wheeled vehicles the father/mother of cars, if we want to stay with that analogy. It’s remotely related, not an integral part and nowadays solved differently. But the first car was a tricycle. (Benz Patent-Motorwagen)

      But I don’t want to invalidate her achievements either…

      She didn’t invent frequency hopping, Nicola Tesla did She invented a system that used a piano roll (from a player piano) to alternate frequencies.

        Or rather she was part of a team, with her husband and one more, that patented that idea, never really got it to work in real torpedos, and the technology was forgotten until someone referred to it in a later patent. Then her role as background got expanded to take the role of other more influential women, maybe because she had a nicer picture.

    For the Bluetooth development, the developers of the technology didn’t know about her patent until their IP department was about to file for a patent. They added this patent to the list and then they got connected. As is the case with many, patent and patent connections. It’s a quite common way of how patents are connected, and part of the IP industry. R&D people come up with an idea, these people don’t read tons of patents but solve issues in an intuitive way. Then IP lawers dig into existing patents and make the legal connections.
