Abstract: A semiconductor wafer is inspected using a main laser beam and a secondary laser beam. The secondary laser beam leads the main laser beam and has lower power than the main laser beam. Using the secondary laser beam, a particle is detected on the semiconductor wafer having a size that satisfies a threshold. In response to detecting the particle, the power of the main laser beam and the power of the secondary laser beam are reduced. The particle passes through the main laser beam with the main laser beam at reduced power. After the particle has passed through the main laser beam with the main laser beam at the reduced power, the power of the main laser beam and the power of the secondary laser beam are restored in a controlled manner that is slower than a single step.

Abstract: The present invention relates to a fiber optic telecommunication cabinet for use in fiber optic telecommunication networks. The fiber optic telecommunication cabinet comprises a base and a housing. The base has a plurality of ports passing through the base to allow passage telecommunication cables into the fiber optic cabinet. The fiber optic telecommunication cabinet further includes an optical fiber termination block attached to the base. The optical fiber termination block has a plurality of optical modules supported by the mounting frame, wherein the optical modules may be rotated in a plane perpendicular to the longitudinal direction of the fiber optic telecommunication cabinet from a first storage position to a second accessible position.

Abstract: The present invention relates to a fiber optic telecommunication cabinet for use in fiber optic telecommunication networks. The fiber optic telecommunication cabinet comprises a base and a housing. The housing defines an internal cavity from an open first end that extends longitudinally to a closed second end. The base is configured for attachment to the open first end of the housing to provide an enclosed configuration. The base has a plurality of ports passing through the base to allow passage telecommunication cables into the fiber optic cabinet. A center support column extends from the base from the base. The fiber optic cabinet includes a plurality of patch panel frames disposed radially around the center support column and a patch cord management plate attached to the center support column above the plurality of patch panel frames.

Abstract: The present invention recognizes that the limiting structures to size reduction for an optical encoder were the laser diode/photo diode package and the photodetector with amplifier package(s). The invention includes removing the discrete components from the laser diode cover package and mounting the much smaller discrete components on a base framework. The photodetector with amplifier package of the invention have an altered photodetector/amplifier geometry including shortening the leads between them. This resulted in significant size reduction of the encoder, a reduction in required gain and resulting increase in bandwidth. The entire base framework is temperature cooled by disposing two thermo-electric coolers between the base framework and an adjacent heat sink. Such positioning of the two coolers between the base framework and it's adjacent heat sink stabilizes both the laser diode's and the photo detector's outputs.
