ABSTRACT:
An apparatus for affecting at least one physical parameter associated with a shaft oriented about a longitudinal axis includes: a piezoelectric tubular member in a substantially osculatory coaxial relation with at least a portion of the shaft; and at least one electrical network coupled with the piezoelectric tubular member for switchingly completing an electrical path through the piezoelectric tubular member.
