Abstract: A method and system for biasing focusing optics of a miniature camera in a predetermined position are disclosed. A spring can be used to bias the optics in a position for focus at infinity. Such biasing mitigates power consumption, provides a failsafe feature, and mitigates the detrimental effects associated with the use of autofocus upon a subject having fuzzy features.

Abstract: A method and system for limiting the motion of components such as the optics of a camera are disclosed. The system can comprise a stage and a snubber assembly for controlling motion of the stage in six degrees of freedom. For example, the snubber assembly can permit movement in one translational degree of freedom while substantially limiting motion in the other five degrees of motion so as to facilitate focusing and/or zooming of a camera while inhibiting misalignment of the optics and while providing some protection against shock and vibration. Such motion control can be achieved while mitigating costs associated with precision manufacturing of the snubber assembly.

Abstract: In accordance with an embodiment of the present invention, a miniature camera has a first stage and a first optical element formed to the first stage. A motion control assembly is configured to provide movement of the first stage in one degree of freedom while inhibiting movement of the stage in five degrees of freedom, so as to facilitate at least one of focusing and zooming the camera.

Abstract: Micromachined passive alignment assemblies and methods of using and making the same are provided. The alignment assemblies are used to align at least one optical element. The alignment assemblies may be configured with kinematic, pseudo-kinematic, redundant or degenerate support structures. One alignment assembly comprises a base and a payload, which supports at least one optical element. The payload may be coupled to the base via connecting structures. The base, the payload and/or the connecting structures may have internal flexure assemblies for preloading a connection, thermal compensation and/or strain isolation.

Abstract: A micromachined resonator mountable to an external support structure has a proof mass coupled to a base structure by a first spring structure, the base structure having a plurality of electrodes, and a second spring structure coupling the base structure to the external support structure.
