摘要： The current disclosure shows a fiber optic slip ring with through bore, or an off-axis fiber optic rotary joint to provide transmission of optic data between mechanically rotational interface with a through bore. Said fiber optic slip ring with through bore may include a ring assembly and a brush block assembly within a rotor and a stator. Said ring assembly may include a ring, a ring holder and a fiber. Said brush block assembly may include a fiber brush, a brush block, an optic index matching fluid, and shaft seals. Said ring may be a donut-shaped waveguide with flat surface on one side. Said fiber brush may have an angled-surface, which is fully contacted with said flat surface on said ring at any time so that during the rotation of said rotor, the optic signal can be transmitted between said fiber and said fiber brush in either direction.

摘要： A low insertion loss, low back reflection fiber optic rotary joint with increased data throughput capabilities has been invented. This is accomplished by using a dispersion free prism with optical coatings to minimize the amount of back reflection caused by the optical beam passing through the prism-air interface.

摘要： A multi-pin connector with a small envelop and low insertion loss capable of operating while submerged is described within. This configuration avoids the tolerance stack up troubles that has plagued other similar designs thereby allowing it to achieve a low insertion loss without the typical cost drivers of tighter tolerances. In addition this invention incorporates as relatively simple method of tuning each pair of connectors thereby further reducing the insertion loss for each matched pair.

摘要： The current invention is regarding an electrical slip ring system for high speed applications, which require slip rings to operate at speeds more than 60,000 RPM. It consists of multiple single stage slip rings and multiple gear devices, where all the stators, except the last one, are rotational. The speed limit on the slip ring market, by using the advanced fiber brush bundles, is about 10,000 RPM without cooling, or lubricating. The basic idea is that by designing gears, we can always can make sure the relative speed between the rotor and the stator in each stage is

摘要： The current disclosure is regarding an electrical slip ring assembly that transmit signals, data, and power across rotary platforms, especially for high frequency applications. The high frequency slip ring assembly with through bore may include a first stage slip ring, a second stage slip ring, a gear assembly, and an internal cable assembly. Rings may have an angled notch on a circumference to break said rings and have the same diameter. The first stage slip ring and second stage slip ring may be connected in series sequence, i.e., the stator in first stage slip ring is mechanically connected with the rotor in second stage slip ring. The internal cable assembly electrically connects the brush assembly in first stage slip ring with the ring assembly in said second stage slip ring in each channel respectively.
