Abstract: This invention is directed towards ophthalmic lenses used to assist during vitreoretinal surgery. More specifically, it is directed towards ophthalmic lenses that are constructed to generate a high-resolution image of the retinal surface during surgery while maintaining a minimal mechanical envelop all while using materials and assembly methods compatible with autoclave sterilization techniques.

Abstract: A laser diode based system for direct injection of selected thermal-infrared (IR) wavelength radiation or energy into articles for a wide range of processing purposes is provided. These purposes may include heating, raising or maintaining the temperature of articles, or stimulating a target item in a wide range of different industrial, medical, consumer, or commercial applications. The system is especially applicable to operations that require or benefit from the ability to irradiate at specifically selected wavelengths or to pulse or inject the radiation. The system is particularly advantageous when functioning at higher speeds and in a non-contact environment with the target.

Abstract: An autoclavable diagnostic ophthalmic lens system includes a biconvex lens element having front and rear surfaces and a housing in which the biconvex lens element is mounted. The biconvex lens element is fabricated from a glass having an index-of-refraction greater of 1.7 or greater. The glass composition meets the following parameters: (% SiO2 (by weight)+% B2O3) is less than 50%; % of alkali metal compounds+% of alkaline earth metal compounds is less than 10%; and (% SiO2+% B2O3)/(% rare earth compounds) is less than 1.

Abstract: This application relates to an apparatus and method for providing patterned illumination fields for use within process control and article inspection applications. More specifically, it pertains to the use of patterned illuminators to enable visual surface inspection of polished objects such as ball bearings. The use of patterned illuminators properly disposed in relation to a polished part under inspection allows small surface imperfections such as scratches and pits to become visible against the normal surface background. The use of carefully engineered illuminators facilitates advantageous defect-site scattering from generally dark field sources. The patterned nature of the illuminators defined by this invention allows the complete surface of three-dimensional parts to be effectively highlighted using dark field illumination fields.

Abstract: This application relates to an apparatus and method for automated inspection of formed metal containers. More specifically, it pertains to the use of machine vision systems to identify and correlate manufacturing defects occurring in formed food and beverage containers to specific manufacturing paths or sources of origin (eg., body makers) used in the container forming process. The disclosed invention is enabled by the placement of a machine-readable code on specific portions of the can body during the forming process and the use of illumination exposure techniques.

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.

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.
