Patent ID: 8107157

Claim:
An actuator assembly comprising: a. an outer frame; b. a first plurality of fixed comb-teeth connected to the outer frame and extending in a first direction; c. an inner frame formed in a conductive layer and flexibly connected to the outer frame, the inner frame having a first common axis; d. a second plurality of movable comb-teeth connected to the inner frame and extending in the first direction, wherein the first and second pluralities of comb-teeth are horizontally offset from a perspective perpendicular to the first direction and the first common axis; and e. a mirror member connected to the inner frame and movable with respect to the inner frame along a second common axis; f. a torsion bar formed in the conductive layer and connecting the inner frame to the outer frame, wherein the torsion bar is thinner than the second plurality of movable comb-teeth in a second direction perpendicular to the first and second axes.
