Abstract:
1. A system for positioning a payload within a miniature electronic device, comprising: a generally planar first stage having a damper coupled thereto for damping movement of the first stage within the plane of the first stage; a generally planar second stage coupled to the payload and having an opening therein, the first stage being supported within the central opening of and generally coplanar with the second stage by a first plurality of flexures; a generally planar support frame having an opening therein, the second stage being supported within the opening of and generally coplanar with the support frame by a second plurality of flexures; an actuator coupled to at least one of the first and second stages; and, a controller in communication with the actuator, the controller being configured to generate an excitation waveform corresponding to a desired position of the payload within the electronic device.
