  • Patent number: 8705018
    Abstract: An arrangement for, and a method of, accurately determining at least one optical property, such as coverage and/or symmetry, of a gemstone, employ an energizable, stationary light source for directing light rays at different orientations to an uncovered table of the gemstone, and an energizable, stationary backlight spaced away from a culet of the gemstone. A controller energizes the light source to generate return light from the gemstone for each light ray, and energizes the backlight to illuminate the gemstone from behind. An imager images the return light as a plurality of frontlit images, and images the backlit gemstone as a backlit image. The controller processes at least one of the images to determine the optical property of the gemstone.

  • Publication number: 20110205525
    Abstract: A gemstone to be optically examined is held by a holder having an internal compartment. A mounting plate supports the gemstone table-side up in an upright position within the internal compartment. A protective lid is mounted on the holder for movement between a closed position in which the lid overlies the mounting plate and the gemstone supported thereon, and an open position in which the lid uncovers the gemstone for optical examination.

  • Publication number: 20060041451
    Abstract: The present disclosure relates to simulating one or more lighting environments, allowing consumers to select and/or learn about beauty products and/or other products having and/or causing an appearance that varies depending on lighting conditions. Simulated lighting environments can also be used for development and testing of beauty products by determining the performance and interaction of one or more beauty products with other beauty products and/or various individual skin-tones, hair colors, etc. in the different lighting environments.

  • Publication number: 20050007780
    Abstract: A modular light assembly is provided. The light assembly includes a light housing with sides, an electrical light source inside the housing and connected to a connector on at least one side of the housing, and a pin for pivotally, electrically and detachably connecting the side with the connector to a side of another housing having the connector. The connector includes a quarter turn receptacle set into a dielectric medium, which is surrounded by a conductive metal ring. The electrical light source may be a plurality of LED lamps connected to a printed circuit board, which is connected to the connector. The light assembly may also be connected to other electrical and non-electrical devices having a connector.
