The Nexus Trilogy a treadmill in Kyoto, Japan. Later work done by Phillip Kennedy and colleagues built the first intracortical brain–computer interface by implanting neurotrophic-cone electrodes into one man, Johnny Ray, a stroke victim unable to move muscles below his face. With the connection made, the electrodes can record the electrical impulses that travel across neurons when thinking occurs. Those signals are transferred to a transmitter embedded beneath the scalp. Amplified 1,000 times, the signals go to a computer, which translates them into cursor movement, allowing him the ability to communicate simply by thinking. Other research has seen success with sensory data, including
Signals, Crane and Subway, Charters Towers railway station the signal box, although electrical or hydraulic operation could be used for more distant signals. At night, lights were necessary, and kerosene lamps with movable coloured spectacles displayed different colours, including green (proceed), yellow (prepare to find next signal red), and red (stop). Later, electrical coloured lights were used. Smaller points indicator signals, which confirmed whether or not points had been switched, could be used for shunting within a railway yard, and the most common form was the rotating disk signal. These could also contain a kerosene lamp for night operation. To coordinate signals so that is impossible to give
