I would take issue with the Bluetooth one - it was invented by Ericsson, AIUI.
It was called Bluetooth by an Intel engineer, who was reading a novel about the Vikings, and in particular King Harald Bluetooth, who united all the various Danish, Swedish and Norwegian viking tribes, as Bluetooth was supposedly invented to provide a single wireless communication protocol.
THe Bluetooth logo is an amalgamation of the Norse runes for the letters H and B - after Harald Bluetooth.
EDIT
Did a bit of digging. My assertion is correct, Bluetooth was indeed invented by Ericsson.
HOWEVER
Austrian actress Hedy Lemarr did come up with the concept of spread-spectrum transmission, aka "Channel Hopping", transmitting radio signals at a frequency which changed throughout the transmission. If you varied the frequency, anyone trying to intercept or jam the transmission would not know what frequency to target their efforts at.
She came up with the idea in the 1940s, but it was ignored until the late 50s, early 60s. The principle underpins virtually all secure radio transmissions today, including Bluetooth, as well as cellphones and Wifi.
