Abstract:
1. A system for positioning a functional element, comprising: a) a housing; b) a primary guide pin coupled to the housing and registered relative to the housing; c) a functional group movably coupled with the primary guide pin, comprising a functional element, a first friction surface, and a second friction surface, the first and second friction surfaces are oriented relative to one another at one of an obtuse angle and a straight angle; and d) a vibrational actuator assembly coupled to the housing and substantially registered relative to the housing, and including a first drive element and a second drive element, wherein the first drive element is configured to interact with the first friction surface and the second drive element is configured to interact with the second friction surface, and the vibrational actuator assembly operates to translate the functional group, wherein the first drive element and the second drive element are each in the form of a hollow cylinder.
