Abstract
An electromechanical translation apparatus comprising a driven member which is adapted to be incrementally moved in a selected direction, and a piezoelectric multiaxis micropositioner adapted to produce incremental movement of the driven member in the selected direction wherein the micropositioner includes a mounting means, at least one piezoelectric driver assembly having a housing, an engaging member formed of a hard material having a selected driving end at one end thereof and a driven end at the other end wherein the engaging member's one end is positioned to selectively engage and translate said driven member in response to a driving force, and at least three piezoelectric driver elements positioned between the driven end of the engaging member and the housing wherein the piezoelectric driver elements are positioned in a spaced, angular relationship to the others and wherein each piezoelectric driver element is capable of separately responding to an electrical signal having a predetermined frequency and amplitude which varies between a first polarity and second polarity to expand and contract to change its geometrical dimension to apply a driving force on the engaging member which imparts an incremental movement to the driven member in the selected direction is shown. The use of an electromechanical translation apparatus as a piezoelectric multiaxis micropositioner for incrementally rotating a sphere having an optical element affixed thereto for use in an optical path is also shown.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
