  • Patent number: 7137309
    Abstract: A modular split-axis stage is used to inspect and/or repair large flat glass media suitable for LCD/TFT applications. Low-precision air table sections are detachably mounted to a centrally located, high-precision granite inspection/repair section. Glass media held by a vacuum contact is transported on air cushions from the up-web air table to the central inspection/repair section. Vacuum nozzles integrated with porous medium pads precisely control the height of the flexible media above the central section during inspection or repair. Embodiments includes structures in which the media is either stationary or moving during inspection/repair. A first media can be loaded/unloaded while a second media is undergoing inspection or repair in a pipelined operational mode.

  • Patent number: 6683421
    Abstract: A photocuring device and a method of photocuring using it. The device includes a housing and a light emitting semiconductor array mounted to the housing, capable of emitting light energy having a light output wavelength suitable for initiating a photoreaction. The device also has a power source for providing power to energize the array to emit light energy and a controller coupled to the power source for varying the power provided by the power source to the array.

  • Publication number: 20020172048
    Abstract: A light source locking mechanism comprising a housing configured to receive a light source, wherein the housing has a central axis. The locking mechanism also includes an engaging mechanism coupled to the lamp housing and radially disposed about the central axis. The engaging mechanism comprises a plurality of rollers to releasably engage the light source as well as a biasing apparatus coupled to the rollers to flexibly bias the rollers towards the central axis.

  • Publication number: 20020114896
    Abstract: A method and system for curing reactive material. The system includes a generator capable of generating radiation, a power supply operatively coupled to the generator, and an emitter adapted to emit the generated radiation onto the material. The system also includes a temperature sensor capable of detecting the temperature of the material a controller adapted to control the power level of radiation emitted. The system also preferably includes a masking unit for shaping the emitted radiation to substantially match the profile dimensions of the reactive material. In one embodiment, the method includes the steps of generating radiation within the absorption spectrum of the reactive material; shaping the generated radiation to substantially match the dimensions of the reactive material; and emitting said shaped radiation onto the reactive material.
