摘要： Described herein are rotary transformers for coupling signals between components that rotate relative to one another. In an exemplary embodiment, a rotary transformer comprises a rotary shaft, a first magnetic core on the rotary shaft, and a first winding wound around the first magnetic core. The rotary transformer further comprises a hollow second magnetic core, and a second winding wound along the inner wall of the second magnetic core. During operation, the first winding on the rotary shaft rotates within the second winding with the magnetic cores magnetically coupling signals between the two windings. Also, the first and second windings are closely spaced to provide capacitive coupling between the windings that extends the frequency response of the transformer. In one embodiment, the windings comprises substantially flat conductors wound in the shape of the windings. In another embodiment, each of the windings comprises circular loops connected by jogs.

摘要： An electrical connector is described. In one implementation, the connector includes a female portion including one or more electrical contacts and a male portion including one or more electrical contacts. The female portion and the male portion each have a self-orientating geometry that allows the male portion to be mated with the female portion in any rotational position along 360 degrees of rotation. When mated, the electrical contacts of the female portion mate with corresponding one or more electrical contacts of the male portion to form one or more electrical connections between two electronic components.

The imaging core includes a rotatable driveshaft, one or more transducers, one or more conductors, and a conductive shield. The one or more transducers are mounted to the rotatable driveshaft. The one or more conductors are coupled to the one or more transducers and extend along the driveshaft. The conductive shield is disposed around the one or more conductors. The shield-coupling capacitor is electrically coupled to the conductive shield and includes one or more rotating capacitors. The one or more rotating capacitors include one or more rotating plates and one or more stationary plates. The shield-coupling capacitor is configured and arranged for coupling to a system ground.
