Abstract:
1. A microelectromechanical tiltable-platform apparatus, comprising: (a) a substrate; (b) a platform tiltably supported above the substrate by a plurality of flexures, with each flexure being connected to the platform proximate to an outer edge thereof through a compliant member; (c) at least three gear-driven racks located on the substrate and moveable in the plane of the substrate, with one of the racks being connected to an end of each flexure to tilt the platform in response to movement of at least one of the racks by a rotary microengine located on the substrate; and (d) a thermal actuator operatively connected to an end of each rack opposite the flexure to act in combination with the rack to initially uplift the platform above the substrate.
