Abstract:
A two position optical actuator device, comprising:a mounting base; an actuation arm having a first end, a second end, and a middle region, said middle region being rotatably connected to said mounting base, said first end including an elongated opening; an optical element attached to said actuation arm second end; a driver bar, having a first end rotatably connected to said mounting base and a second end on which is mounted a bearing for engaging and traveling within said elongated opening, for driving said actuation arm between actuation arm first and second positions when said driver bar pivots from driver bar first and second positions, so that when said driver bar pivots in a given direction said actuation arm is driven in an opposite rotational direction by said bearing; powered means for applying a restraining force to said driver bar to hold said driver bar in driver bar first position; and non-powered means for applying a driving force to said driver bar which causes said driver bar to pivot from said driver bar first position to driver bar second position when said powered means ceases to apply said restraining force to said driver bar.
