Patent ID: 7616372

Claim:
A micro-electro-mechanical (MEMs) device comprising: a platform pivotable about first and second perpendicular axes above a substrate; a pedestal extending upwardly from the substrate underneath the platform; a first hinge extending from the pedestal enabling the platform to tilt about the first axis; a gimbal frame extending at least partially around the first hinge for receiving an outer end of the first hinge; and a second hinge extending from the gimbal frame to an underside of the platform enabling the platform to roll about the second axis; wherein the first and second hinges are disposed entirely underneath the platform to enable adjacent MEMs devices to be closely packed together; wherein the first hinge comprises a pair of serpentine torsional beams extending from opposite sides of the pedestal along the first axis into contact with the gimbal frame; and wherein the second hinge comprises a pair of serpentine torsional beams extending from opposite sides of the gimbal frame along the second axis.
