Abstract: A method for detecting actual slip in a coupling of a rotary shaft, for example, in a wind turbine power system, includes monitoring, via a controller, a plurality of sensor signals relating to the coupling for faults. In response to detecting a fault in the plurality of sensor signals relating to the coupling, the method includes determining, via the controller, whether the fault is indicative of an actual slip or a no-slip event of the coupling using one or more classification parameters. When the fault is indicative of the actual slip, the method includes estimating, via the controller, a magnitude of the actual slip using the plurality of sensor signals and a time duration of the actual slip. Further, the method includes implementing, via the controller, a control action based on the magnitude of the actual slip in the coupling.

Abstract: A nebulizer assembly configured for removable attachment to an ultrasonic actuator includes a base plate portion, a porous mesh member, and a cover member. The base plate portion includes an opening extending therethrough, and is substantially rigid such that ultrasonic vibrations from the ultrasonic actuator may be transmitted through the base plate portion to the porous mesh member to vibrate the porous mesh member. The porous mesh member is configured for passage therethrough of a nebulized fluid, and is disposed in the opening of the base plate portion proximate a fluid emission side of the nebulizer assembly. The cover member is disposed on a second side of the nebulizer assembly opposite the fluid emission side. The cover member covers the opening and defines a cavity between the cover member and the porous mesh member. The cavity is configured to retain a fluid to be nebulized.
