A bearing assembly is disclosed. The bearing assembly includes a first race. Further, the bearing assembly includes a second race disposed concentric to the first race, where the second race has a radius that changes along an axial length of the bearing assembly. The bearing assembly also includes a housing disposed around the second race and operatively coupled to the second race. Moreover, the bearing assembly includes a plurality of support structures configured to detachably couple the second race to the housing, where the plurality of support structures are configured to disengage the second race from the housing to allow motion of the second race when a torque on the second race is greater than a threshold torque value.

Bearing assembly and method

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.

Nebulizer systems and methods

The present disclosure relates to methods for manufacturing porous mesh plates for use in ultrasonic mesh nebulizers, and the porous mesh plates manufactured by those methods. Cone-shaped dimples are first drilled in a substrate (e.g. a plate), but do not penetrate the bottom of the substrate. Next, the substrate (e.g. a plate) is subject to an electrochemical process to remove a layer of material from the surface of the substrate. Enough material is removed to allow the dimples to penetrate the substrate, thereby creating holes in the substrate. The size of the holes can be controlled by the conditions of the electrochemical process.
