Optical transmission for rotating device from rotating component to stationary hub

A moving rotor transmits signals to a stator using lights at some wavelength (visible, infrared, UV, etc.). These lights are lit/extinguished in a pattern, with timing algorithms to distinguish which sensor should detect which light source.

Sensors are staggered to allow constant transmission by switching from an "outer" to an "inner" sensor right every 1/2n period, where n is the number of receiving sections. Therefore, the transmission bandwidth is theoretically limited by the rate at which the light can switch on and off. This gives the potential for high-speed optical data transmission using no physical connector.

    The invention herein transmits signals from a moving rotor to a stator using optical/infrared signal emitters. It allows a fan to send signals from the rotating part to the stationary part for further transmission. Optical transmitters for high speed or LED lights (low speed transmission) are placed on the rotor of a rotational platform (similar to a fan hub), which is the computing device. These transmitters send signals from the rotor to the stator. Multiple signaling devices may be placed concentrically, such that multiple signals are sent at the same time for each blade "section." Figure 1 below gives an idea of the device which could use this signaling system. It consists of a rotor, which functions as a computer and must transmit signals to the stator, which fu...
