US Patent:

7646969, Jan 12, 2010
Filed:

Nov 8, 2005
Appl. No.:

11/268849
Inventors:

Robert J. Calvet - Pasadena CA, US
Roman C. Gutierrez - Arcadia CA, US
Kumaraswamy Jayaraj - San Diego CA, US
Tim Quang-Tinh Ngo - San Diego CA, US
Assignee:

Siimpel Corporation - Arcadia CA
International Classification:

G03B 17/00
G02B 7/02
US Classification:

396 79, 359823
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.

Filed:

Oct 17, 2006
Appl. No.:

11/550119
Inventors:

Davy Tong - Temple City CA, US
Shi-Sheng Lee - Arcadia CA, US
Kumaraswamy Jayaraj - San Diego CA, US
Assignee:

Tessera MEMS Technologies, Inc. - Arcadia CA
International Classification:

G03B 3/00
G02B 7/02
US Classification:

396144, 359823
Abstract:

A method and system for mitigating undesirable motion of the optics of a camera are disclosed. The system can include a stage and snubber assembly for defining motion of the camera optics. The stage and snubber assembly can include a stage assembly having a stage to which the optics are attachable, at least one wing formed upon the stage, and a snubber assembly configured to cooperate with the wing(s) so as to limit motion of the stage substantially to the desired direction of travel of the camera optics.

Filed:

Feb 24, 2006
Appl. No.:

11/361608
Inventors:

Roman C. Gutierrez - Arcadia CA, US

Guiqin Wang - Arcadia CA, US
Kumaraswamy Jayaraj - San Diego CA, US
Assignee:

Tessera MEMS Technologies, Inc. - Arcadia CA
International Classification:

G03B 3/10
US Classification:

396133, 396439, 396452
Abstract:

A method and system for facilitating focusing of a miniature camera are disclosed. One or more lenses can be attached to a MEMS stage. The MEMS stage can be moved by a Lorentz actuator. The MEMS stage can be configured to limit movement of the lens(es) to a single degree of freedom to inhibit misalignment thereof with respect to an imaging sensor. The stage can be biased to a predefined position thereof, e. g. , for focus at infinity. A metal cover can inhibit electromagnetic interference and can limit movement of the lens(es).
