Abstract: A gas control valve includes two blocks with a mediate plate located therebetween. Each of the two parts has a gas path facing the mediate plate which has a passage which communicates with the two gas paths. A sleeve is engaged with a hole in one of the two parts and a rod is movably received in said sleeve. A first end of said rod is movably inserted in said second gas path and can be lowered to seal the passage in the mediate plate. A memory member or bi-metal has a first plate fixedly connected on a top of said sleeve and a second plate fixedly mounted to said second end of said rod. The memory member or bi-metal is located in the gas combustion chamber and can be deformed according to the temperature to lower the rod to obtain less gas flow.

Abstract: A method and apparatus for presbyopia correction are disclosed. The disclosed preferred embodiments of the system consists of a beam spot controller, a beam delivery device, a slit lamp, a visible aiming beam and a selected solid state laser having a wavelength of (0.9-1.4) microns.

The near infrared laser is focused and delivered by a gonio lens to the target zonnulas area and viewed by a surgeon using a slip lamp. The selected laser having an optimal absorption characteristics is tightly focused such that only the target zonnulas is heated, while the cornea, the lens body and the adjacent areas are not damaged.

Abstract: An optical coupler that provides for the direct mounting of integrated circuit(s). The coupler includes a two-part housing with grooves for accommodating optical fibers that are held in place when the two parts are put together. Circuitry is formed on the housing and solder balls, when heated to a liquid state and cooled (reflowed), are used to attach integrated circuit(s) onto the housing. At least one of these integrated circuit(s) is an optical die that is positioned in close proximity to the optical fibers to provide for the receipt and/or transmission of optical signals. The reflowing of the solder balls forms an electrical connection between the circuitry on the housing and the integrated circuit(s) and provides for alignment of these components. The housing is attached to a circuitized substrate using reflowed solder balls or wirebonds.

The block is heated and pressed against the complimentary articulating bearing surface, thereby forming the articulating bearing surface.

Abstract: An optical fiber guide includes a matrix of holes integrated directly into a substrate on which one or more optical chips are mounted. The substrate therefore functions both as a guide for optically coupling a plurality of optical fibers to an optical chip, as well as a carrier for the optical chip itself. The size of the fiber guide and its integration density is therefore improved over conventional fiber connectors. The substrate is preferably made of a material having a coefficient of thermal expansion substantially similar to the coefficient of thermal expansion of the optical chip. This ensures that the optical fibers will remain optically coupled to the chip through the matrix of holes in the substrate regardless of external temperature influences. If desired, integrated circuits may be mounted onto the substrate to increase the functionality of the fiber guide.
