Appl. No.:

09/839693

Inventors:

Winston Way - Irvine CA, US
Ming Chia Wu - Irvine CA, US
Ming-Bing Chen - Irvine CA, US

Assignee:

OpVista, Inc. - Irvine CA

International Classification:

H04B 10/04

US Classification:

398186, 398183

Abstract:

An optical carrier notch filter includes an optical coupler with at least first, second and third ports. The first port is configured to receive an output that includes an optical carrier and interleaved optical single sideband signals. An optical bandpass filter is coupled to a port of the optical coupler. The optical bandpass filter separates the output into a transmitted signal that contains the optical carrier, and a reflected signal that includes the interleaved optical single sideband signals. The reflected signal is reflected from the optical bandpass filter to the third port of the optical coupler.

International Classification:

H01H 51/22

US Classification:

335 78, 200181

Abstract:

A micro-electromechanical system (MEMS) switch formed on a substrate, the switch comprising a transmission line formed on the substrate, a substrate electrostatic plate formed on the substrate, and an actuating portion. The actuating portion comprises a cantilever anchor formed on the substrate and a cantilevered actuator arm extending from the cantilever anchor. Attraction of the actuator arm toward the substrate brings an electrical contact into engagement with the portions of the transmission line separated by a gap, thus bridging the transmission line gap and closing the circuit. In order to maximize electrical isolation between the transmission line and the electrical contact in an OFF-state while maintaining a low actuation voltage, the actuator arm is bent such that the minimum separation distance between the transmission line and the electrical contact is equal to or greater than the maximum separation distance between the substrate electrostatic plate and arm electrostatic plate.

International Classification:

G01J 5/00

US Classification:

2503381

Abstract:

A method for manufacturing a sensing device, such as a bolometer device or other devices. The method includes providing a substrate, e. g. , silicon wafer. The method includes forming a first reflection layer overlying the substrate and forming a first electrode layer overlying the substrate. The method includes forming a sacrificial layer overlying a portion of the first reflection layer and a portion of the first electrode layer. The sacrificial layer is patterned using photolithography techniques. The patterned sacrificial layer corresponds to a cavity region. The method also forms a second electrode layer overlying the sacrificial layer and forms an elastic layer overlying the patterned sacrificial layer. The elastic layer encloses the cavity region corresponding to the patterned sacrificial layer. The method releases the sacrificial layer to form an opening in the cavity region.

International Classification:

A61B 17/03

US Classification:

606213

Abstract:

A device, system, and method for providing access to, and sealing of, a body organ includes an implant device. An implant device has a main body having an internal access lumen, with a plurality of prongs extending from a distal end of the main body. The main body can include two lumens, one slidable within the other, to form a single continuous lumen with an adjustable length. The main body has an expanded configuration with an expanded diameter, and an unexpanded configuration with an unexpanded diameter. The prongs have a generally straight configuration where they extend distally of the distal end of the main body, and a bent configuration where the prongs bend around so that their tips extend proximally of the distal end of the main body. The device may include a hemostatic barrier to prevent fluid leakage therethrough when the main body is in the unexpanded configuration.

International Classification:

A61B 17/04

US Classification:

606232

Abstract:

Disclosed herein are exemplary embodiments of suture securement devices that replace the need to tie knots in sutures. Some embodiments comprise an annular outer body and one or more suture engagement tabs extending inwardly from the outer body. The devices can comprise a superelastic and/or shape-memory material and have a generally in-plane initial configuration. The suture engagement portions are deformable out-of-plane to an active configuration with the outer body compressed and the tabs interlocked with each other. The device can be heat-set in the deformed configuration. The interlocked tabs exert a pinching force on sutures passing between them that restricts the sutures from sliding through the opening in one longitudinal direction.

Abstract:

A method and apparatus for attaching tissue to bone in a shifted position without requiring surgical detachment of muscle or connective tissue joining the tissue layer to the bone layer. The skin layer is gently pulled in a non-surgical manner and a fastener of the invention is driven through the skin layer into the bone layer to effect a “skin tightening” procedure.
