  • Patent number: 6252977
    Abstract: A reliable method of illuminating and imaging an eye through eyeglasses uses a carefully selected subset of multiple monochromatic light sources, a camera with an imager that exhibits minimal blooming, and a narrow-bandwidth optical bandpass filter to filter out most of the ambient illumination while passing most of the light from the system's own illuminator.
    Type: Grant

  • Patent number: 6088470
    Abstract: A reliable method and apparatus for illuminating and imaging eyes uses multiple light sources producing multiple images of a subject each created under illumination by different illuminators. A composite image of the subject is formed by selecting pixels based upon their gray scale values or using pyramid image processing. A composite image can be created which is free of bright spots commonly caused by reflection of illumination from eyeglasses that may be worn by a subject or for which is free of dark shadows or which is free of both bright spots and dark shadows.

  • Patent number: 5963664
    Abstract: A system for generating three-dimensional mosaics from a plurality of input images representing an imaged scene. The plurality input images contain at least two images of a single scene, where at least two of the images have overlapping regions. The system combines the images using a parallax-based approach that generates a three-dimensional mosaic comprising an image mosaic representing a panoramic view of the scene and a shape mosaic representing the three dimensional geometry of the scene. Specifically, in one embodiment, the system registers the input images along a parametric surface within the imaged scene and derives translation vectors useful in aligning the images into a two-dimensional image mosaic. Once registered, the system generates a shape mosaic representing objects within the scene.

  • Patent number: 5923791
    Abstract: Disclosed is a technique for deriving a composite video image by merging foreground and background video image data supplied from a plurality of separate video signal sources employing pattern-key insertion, rather than prior-art color-key insertion, for this purpose. Pattern-key insertion involves replacing a first pattern in a video scene with a second pattern. This is accomplished by first detecting the first pattern in the video scene and estimating the pose of this detected first pattern with respect to a reference object in the video scene. The second pattern is then geometrically transformed using the pose estimate of the detected first pattern. Finally, the detected first pattern is replaced with the geometrically-transformed second pattern.

  • Patent number: 5751836
    Abstract: Iris recognition is achieved by (1) iris acquisition that permits a user to self-position his or her eye into an imager's field of view without the need for any physical contact, (2) spatially locating the data defining that portion of a digitized video image of the user's eye that defines solely the iris thereof without any initial spatial condition of the iris being provided, and (3) pattern matching the spatially located data defining the iris of the user's eye with stored data defining a model iris by employing normalized spatial correlation for first comparing, at each of a plurality of spatial scales, each of distinctive spatial characteristics of the respective irises that are spatially registered with one another to quantitatively determine, at each of the plurality of spatial scales, a goodness value of match at that spatial scale, and then judging whether or not the pattern which manifests solely the iris of the user's eye matches the digital data which manifests solely the model iris in accordance

  • Patent number: 5161699
    Abstract: A collapsible display stand which comprises a plurality of boxes and a base structure. Each box has an end wall, top and bottom walls, and a pair of side walls. These walls of each box define an internal space for accommodating products. The end wall of each box closes a first end of the box. Each box has a second end opposite the first end. The boxes are fixedly stacked one on top of another to form a stair structure wherein each box is secured at its botttom wall near the first end thereof to the top wall of the lower adjacent box near the second end of the lower adjacent box. Each box has at least one opening for permitting access to its internal space. The base structure is separably engaged with one or more of the boxes, and supports the stair structure in a tilted manner such that the first end of each box is lower than the second end.

  • Patent number: 5016761
    Abstract: In a transportable display module for a plurality of containers, a base member supports a first layer of containers, and a plurality of layers each comprising a tier sheet alternate with a plurality of layers of containers. The tier sheets are identical, with a circumferential skirt surrounding each tier sheet. The top surface of each tier sheet includes an array of container bottom receiving recesses. The bottom surface includes an array of container top receiving recesses disposed concentric with the bottom receiving recesses. Each tier sheet has about its circumferential skirt an outwardly extending flange, and the module is surrounded by plastic film. The base member is a single piece including an upper portion having an additional one of the tier sheets, with a lower portion affixed thereto and including a plurality of supporting legs. Overlay sheets provide for loading other forms of containers, and a cap sheet enabling stacking of multiple modules is disclosed.

  • Patent number: 4589349
    Abstract: For use as a component of a display stand, an extendible shelf comprises a pair of elongated primary bracket elements each arranged for mounting at one end thereof on suitable supporting means such as a pair of upright elements forming components of a display stand, a pair of secondary bracket elements telescopically mounted respectively on said primary bracket elements, a main shelf element supported at its ends by the secondary bracket elements, and a collapsible shelf element including at least two hingedly connected parts one of which is hingedly connected with the rear of said main shelf element and the other of which is hingedly connected with said primary elements respectively, said collapsible shelf element being in collapsed condition when said main shelf element is in its retracted position and being effective to form a supplementary shelf at the rear of said main shelf element when said main shelf element and said secondary bracket elements are in their extended positions.
