Patent number: 8391700Abstract: 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).Type: GrantFiled: September 1, 2010Date of Patent: March 5, 2013Assignee: Digitaloptics Corporation MEMSInventors: Roman C.

Patent number: 7792421Abstract: 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.Type: GrantFiled: October 17, 2006Date of Patent: September 7, 2010Assignee: Tessera MEMS Technologies, Inc.Inventors: Davy Tong, Shi-Sheng Lee, Kumaraswamy Jayaraj

Patent number: 7646969Abstract: 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.Type: GrantFiled: November 8, 2005Date of Patent: January 12, 2010Assignee: Siimpel CorporationInventors: Robert J. Calvet, Roman C. Gutierrez, Kumaraswamy Jayaraj, Tim Quang-Tinh Ngo

Publication number: 20070052132Abstract: A method for cleaning glass from a molded item includes applying hydrofluoric acid to the molded item. The molded item can be an injection molded item made from a glass filled polymer material. For example, hydrofluoric acid can be applied by immersion, spraying, exposure to vapors, or brushing. The molded item can be friction cleaned, e.g., scrubbed, and/or cleaned via oxygen plasma prior to the application of hydrofluoric acid.Type: ApplicationFiled: September 2, 2005Publication date: March 8, 2007Inventors: Roman Gutierrez, Kumaraswamy Jayaraj, Robert Calvet

Patent number: 6320257Abstract: A hermetically sealed package for at least one semiconductor chip is provided which is formed of a substrate having electrical interconnects thereon to which the semiconductor chips are selectively bonded, and a lid which preferably functions as a heat sink, with a hermetic seal being formed around the chips between the substrate and the heat sink. The substrate is either formed of or includes a layer of a thermoplastic material having low moisture permeability which material is preferably a liquid crystal polymer (LCP) and is a multiaxially oriented LCP material for preferred embodiments. Where the lid is a heat sink, the heat sink is formed of a material having high thermal conductivity and preferably a coefficient of thermal expansion which substantially matches that of the chip. A hermetic bond is formed between the side of each chip opposite that connected to the substrate and the heat sink.Type: GrantFiled: September 27, 1994Date of Patent: November 20, 2001Assignee: Foster-Miller, Inc.Inventors: Kumaraswamy Jayaraj, Thomas E.
