The exciter assembly provides an efficient and reliable approach for transferring the electrical power energy across a rotating interface.

Unidirectional and bi-directional fiber optic rotary joints are disclosed for coupling at least one optical signal across a rotary interface.

The disc (19) has a channel having a number of bearings to produce a rotating interface with the filter (15) and the base (10).

The exciter assembly provides an efficient and reliable approach for transferring the electrical power energy across a rotating interface.

The spin control is a circular graphical user interface that is positioned near a displayed document to which it applies.

Unidirectional and bi-directional fiber optic rotary joints are disclosed for coupling at least one optical signal across a rotary interface.

A spin control graphical user interface is used to display a currently applied option and to receive options from a user.

An external hook system for a rotary-wing aircraft includes a lower frame interface which accommodates longitudinal and lateral loads and an upper frame interface.

The cutting unit comprising a rotatory plate, a blade mounted on the rotatory plate, and protruding member mounted on the rotatory plate.

This results in reducing the revolving mass and the space necessary to accommodate the revolving mass.

The rotatable plate is rotatably mounted on and frictionally engaged with the plate support.

The disc (19) has a channel having a number of bearings to produce a rotating interface with the filter (15) and the base (10).

This rotating electrical machine unit is provided with: a rotating electrical machine; and a cooling device for cooling the rotating electrical machine.

To set its functions quickly and easily, it is also equipped with a new interface: the rotatable Ring Command bezel.
