  • Patent number: 7220378
    Abstract: A stretch blow molding system that condition preforms such that the temperature distribution within the cross-section of each preform is optimized prior to blow molding operations is provided. The system has a temperature measurement and control system capable of directly monitoring both the outside as well as inside surface temperature of preforms at different stages of transport throughout the thermal conditioning section of the system.

  • Patent number: 6967716
    Abstract: This invention relates to an apparatus and method for inspecting multi-layer plastic containers (10). More particularly, the invention relates to such an apparatus and method whereby optical energy absorbing compounds are added to the materials comprising the layer(s) of the container (10) to facilitate inspection thereof. Apparatus comprises a sensor unit (40), an illumination unit (30) for illuminating a portion of electromagnetic spectrum at a near IR wavelength to an inspection zone (20) which is located between the sensor unit (40) and the illumination unit (30). A processing unit (50) which receives an output of the sensor unit (40) and determines the attributes of the multilayer plastic containers (10).

  • Patent number: 6894775
    Abstract: An inspection system is provided comprising at least one detection element (60) sensitive to electromagnetic radiation (20) at a wavelength wherein the object (10) to be inspected is rendered opaque by naturally occurring material molecular absorptions. As such, material defects such as cracks and voids can be detected.

  • Patent number: 6872895
    Abstract: This invention relates to a method and apparatus for mass and/or volume measurements of manufactured articles. More particularly, this invention relates to a method and apparatus for mass and/or volume measurements that can be performed on-line in a part manufacturing process. On-line measurement of the mass or volume of material contained in a specific region of interest of the manufactured items is performed 100% on-line. Real-time process control information is based on real-time measurement of the mass or volume of material contained in a specific region of interest of a manufactured item. Automated quality control inspection for manufactured articles is based on real-time measurement of the mass or volume of material contained in a specific region of interest of manufactured items.

  • Patent number: 5936353
    Abstract: A solid-state lighting unit for automated visual inspection includes a high-density array of light emitting diodes. The packing density of said diode array being limited only by the physical size of the light emitting diode chips and the ability to perform die and wire bond operations on the bare chips. Each diode is disposed on an electrically insulated, thermally conductive base unit. The base unit is, in turn, in a thermally conductive path with a heat dissipator. The provisions made to ensure a thermally conductive path from the individual light emitting diode chips to the heat dissipator combined with the high chip packing densities work together to create a solid-state lighting array capable of producing extremely high illumination fields when operated in either pulsed or continuous current mode.
