Publication number: 20020101571Abstract: A projector having a polymeric housing containing an electrical light source, an image medium support assembly aligned in the light path of the light source, and a lens through which light emanating from the light source exits the housing after passing through an image medium disposed in the image support assembly. The projector is preferably adjustably mounted on a support member comprising a tubular section containing a transformer. The projector can be made with an electric motor inside the housing that causes a wheel comprising multiple fixed images to continuously or intermittently rotate the same or different images sequentially through the light path of the projector. A projector assembly is also disclosed in which a projector is mounted in a frame assembly in combination with a rotating mirror ball that simultaneously redirects the projected image in many different directions and continuously changes the image being projected onto a particular spot on surrounding viewing surfaces.Type: ApplicationFiled: October 22, 2001Publication date: August 1, 2002Inventors: Dale A. Panasewicz, Dennis Futo, Marc Louis Vitantonio, John R. Nottingham, John W. Spirk

Publication number: 20020080433Abstract: In a light unit that converts a false linear light into which a light from a point light source has been converted by a columnar light guide, into a planar light by a plate-shaped light guide, the point light source is arranged only at an end of the columnar light guide at which an angle between a longitudinal direction of the columnar light guide and ridge lines of recesses and projections forming a prism surface is obtuse. Thus, a positional relationship between the point light source and the ridge lines is set so that a main irradiation direction of band-shaped light emitted from the columnar light guide and which has been obtained by converting the light from the point light source to a false linear light is not substantially orthogonal to the ridge lines of the recesses and projections forming the prism surface of the plate-shaped light guide. Consequently, light obtained by totally reflecting this band-shaped light is unlikely to be viewed.Type: ApplicationFiled: December 21, 2001Publication date: June 27, 2002Applicant: NEC CorporationInventor: Masatake Baba

Patent number: 6408136Abstract: A portable zoom camera obscura comprising: a telescopic structure including an inner tube and an outer tube positioned concentrically and slidingly movable relative to each other; a cover with a small, centered imaging hole attached to the imaging end of the outer tube; a semitransparent screen covering the inner end of the inner tube; a cover having a viewing hole and attached to the viewing end of the inner tube; and a diaphragm disk or ruler mounted on the imaging end, and including an aperture which can be positioned in a series of continuous overlapping positions with the imaging hole. The diaphragm disk or ruler also include lenses with different focal lengths, which, when positioned in front of the imaging hole allow the camera obscura to function as a photo-camera.Type: GrantFiled: November 28, 2000Date of Patent: June 18, 2002Inventor: Yoel Netz

Patent number: 5909291Abstract: A color matching system initializes a translator by storing profiles of source and destination color devices which include the coordinates in a calibrated color space of the colorants produced in the source and destination devices and a tonal reproduction curve for each device. Mixing equations and parameters are precomputed to be used in matching calculations of an image including color pixels to be matched. The color gamut is divided into mixing regions in which a given point can be produced by a mixture of two chromatic colorants and the achromatic colorants of the destination device. A technique for selecting a mixing region is included which is based on the slopes of vectors defining the colorants of the destination device, and the sample color to be produced.Type: GrantFiled: June 7, 1995Date of Patent: June 1, 1999Assignee: Apple Computer, Inc.Inventors: Robin D. Myers, Keith McGreggor, Robert Johnson, Konstantin Othmer
