Abrégé
Communications systems and methods for communicating data are provided. In one example, the communications system includes an outer ring having an inner surface and an inner ring having an outer surface. The inner surface and the outer surface are separated by a gap that extends around the inner ring to define a loop. A modulating light arrangement receives data and produces modulated light. A first light diffusing optical fiber and a second light diffusing optical fiber are disposed on a first side of the gap and extend in the loop to define an optical data ring. The first light diffusing optical fiber and the second light diffusing optical fiber cooperate to diffuse the modulated light along the optical data ring. A detector is disposed on the second side of the gap and detects the diffuse modulated light.

Abrégé
A wireless slip ring, system and method for transmission of data across a rotatable junction can be provided to permit transmission of data from a fixed element to a rotating element across a rotary interface. The wireless slip ring can provide high bandwidth multi-channel data transmission, for example each channel can have a bandwidth greater than 1 gigabit per second. Each channel may include a plurality of input/output data streams that can be serialized by a digital electronic circuit for transmission across the slip ring and then deserialized into its respective data streams. The wireless slip ring can form an annular chamber to act as a wave guide for the wireless signal for providing a continuous conductive covering around the annular chamber to act as a faraday shield to contain radio frequency emissions and prevent external jamming.

Abrégé
A direct drive actuator and method of driving a rotor relative to a stator is provided that requires no gearbox, but is capable of producing large instantaneous starting torques, which yields significant advantages to the performance of the system. The actuator includes rotor and stator pole arrays that are held in fixed spaced relationship, which provides a non- contact actuator for reducing wear and required maintenance. A control structure incorporates electronics for precisely commutating the actuator. In particular, each pole array is controlled by a dedicated control circuit or pole controller allowing for precise control of the direction and strength of the generated magnetic field. Each pole array may be selectively energized responsive to each pole controller associated therewith for precisely controlling the magnetically-induced forces at each individual pole independent of the other poles in the array.
