    In the FT this weekend..

    Bluetooth was conceived in 1994 at Ericsson in Sweden, but the company saw little value in it and let it go open-source. Two former employees have a rightful claim to be the inventors. One is a Swedish Navy reserve doctor who had the basic idea and the first patents, the other an engineer who made it work. They live modestly in Gothenburg, Sweden and Groningen in the Netherlands, respectively, with no sign or expectation of Bluetooth riches.

    A third player, arguably the intellectual mother of Bluetooth, was the Hollywood star and part-time physicist Hedy Lamarr, who died in 2000 at the age of 85. It is unknown if she was aware of Bluetooth, or WiFi, or GPS, for which she also laid the groundwork.

    Yes bluetooth uses a frequency hopping approach and Lamarr's patent was for a frequency hopped spread spectrum method.

    Fortunately for Hedy, her talents went far beyond the technical !

    Look at that face and try to tell me you have not seen perfection.
