Abstract: During control of a user interface via free-space motions of a hand or other suitable control object, switching between control modes can be facilitated by tracking the control object's movements relative to, and its penetration of, a virtual control construct (such as a virtual surface construct). The technology disclosed includes determining from the motion information whether a motion of the control object with respect to the virtual control construct is an engagement gesture, such as a virtual mouse click or other control device operation. The position of the virtual control construct can be updated, continuously or from time to time, based on the control object's location.

Abstract: A gearbox including a gear-train including an input and an output and a rotating conduit internally traversing the gear-train is provided. The rotating conduit is configured to receive lubrication fluid from one or more components downstream of the rotating conduit and deliver lubrication fluid to one or more components upstream of the rotating conduit. The components downstream of the rotating conduit rotate at a different speed than components upstream of the rotating conduit.

Abstract: A transmission assembly included in a power generation system of a wind turbine, the wind turbine having one or more wind driven rotor blades. The transmission assembly includes a transmission including an input carrier and a gear-train rotatably coupling the input carrier to a transmission output, the input carrier configured to transfer a rotational input from the rotor blades to the gear-train and a removable input bearing cartridge coupled to a periphery of the input carrier, exterior to the gear-train, the removable bearing cartridge in axial alignment with the input carrier.

Abstract: A transmission, including a gear-train and an outer housing enclosing the gear-train, the outer housing including a torque reacting joint coupling a first section of the transmission to a second section of the outer housing, the torque reacting joint including mating indents between the first and second sections.
